2 Default Settings The LaMarche Communications Card is shipped with the following default settings; Protocol: Set per customer order (DNP 3.0, Modbus ASCII, Modbus RTU, Modbus TCP) Default: DNP 3.0 Comm Port: RS232 (J2) Baud Rate: 9600 Data Bits: Fixed at 8 Stop Bits: Fixed at 1 Parity: Fixed at None Flow Control: Fixed at None Node Address: 4 (0100 Series Software), 90 (1100 Series Software) IP Address: Netmask: Gateway: TCP Port Number: Fixed at for DNP, Fixed at 502 for Modbus Changing the Settings In all likelihood it will be necessary to change the settings from the factory default settings to properly integrate a new charger into your SCADA Network. To change the above settings one must enter the "Customer Calibration" mode. This is accomplished by pressing the switch that activates Equalize and holding it in the "up" position for 5 seconds. When the control card enters the Customer Cal mode the display will show "CAL" for 2 seconds. During the time the display shows "CAL" release the switch. The purpose of the Customer Cal is to allow one to change settings in the field. The following setting changes are allowed in the following order: Low DC Current Alarm Threshold Low DC Current Alarm Reset Threshold Low Voltage 1 Alarm Voltage Threshold High Voltage Alarm Voltage Threshold Equalize Timer Mode Equalize Cycle Time High Voltage Shutdown Alarm Voltage Threshold Temperature Compensation Enable Modbus Address Scada Remote Configuration Mode Scada Protocol Scada Node Address (MSB, B4) Scada Node Address (B3) Scada Node Address (B2 Scada Node Address (B1) Scada Node Address (LSB, B0) Scada Comm Port Scada Baud Rate (Only when Scada Comm Port is either RS232 or RS485) Scada IP Address Quad 3 (Only when the Comm Port is set to TCP) Scada IP Address Quad 2 (Only when the Comm Port is set to TCP) Page 2 of 26

3 Scada IP Address Quad 1 (Only when the Comm Port is set to TCP) Scada IP Address Quad 0 (Only when the Comm Port is set to TCP) Scada Netmask Quad 3 (Only when the Comm Port is set to TCP) Scada Netmask Quad 2 (Only when the Comm Port is set to TCP) Scada Netmask Quad 1 (Only when the Comm Port is set to TCP) Scada Netmask Quad 0 (Only when the Comm Port is set to TCP) Scada Gateway Quad 3 (Only when the Comm Port is set to TCP) Scada Gateway Quad 2 (Only when the Comm Port is set to TCP) Scada Gateway Quad 1 (Only when the Comm Port is set to TCP) Scada Gateway Quad 0 (Only when the Comm Port is set to TCP) Scada Diagnostics Mode The control card when it enters the Customer Cal mode will display "CAL" for 2 seconds, then automatically move to display the first setting which will be the Low DC Current Alarm Threshold. While each setting is displayed, you have the option of changing it by pressing the "EQ" switch "UP" or "Down". "UP" is used to increase setting values and "DOWN" will decrease the settings. To advance to the next setting you must press the HVSD Reset Button. Setting the Modbus Address The following setting are used to set the Modbus Address so the communications card can communicate with the controller card: Modbus Address An Alternating display showing "Addr" for 1 second then the modbus address for 1 second. Hold the down switch until the display shows ALL. The ALL setting sets the controller card up so it will accept commands from the communications card. It also activates the following calibration settings. When the modbus address is not set to all the controller card may not be able to communicate with the communications card. To advance to the next setting you must press the HVSD Reset Button. Setting the Remote Configuration Mode This setting when set to YES places the communications card into a mode where it is then possible to set the card up using a configuration program supplied by LaMarche. This capability has been added in recognition of the shortcomings associated with showing characters on a 7 segment display. Please contact LaMarche if you are interested in using this as a configuration option. The default selection for this setting is NO (displayed as no). Setting this to YES causes the calibration sequence to jump to the end as it is expected the settings will be transmitted to the card using the software utility.. PLEASE NOTE YOU MUST RETURN TO THE CAL SEQUENCE TO DEACTIVATE THIS MODE OR RESET THE CONTROLLER CARD. To advance to the next setting you must press the HVSD Reset Button. Page 3 of 26

4 Setting the Scada Protocol The communications card is equipped with 4 methods of communicating, DNP 3.0, Modbus ASCII, Modbus RTU and Modbus TCP. The following setting is used to set the Scada Protocol: Protocol Each protocol setting is displayed using an alternating "SCdA" for 1 second followed by either " dnp", " ASCi", rtu or " tcp". To change the protocol from DNP to Modbus TCP, press the EQ switch "UP" until the display shows an alternating "SCdA" followed by " tcp". To advance to the next setting you must press the HVSD Reset Button. Setting the Scada Node Address The following settings are used to set the Scada Node Address: Scada Node Address (4), MSB Scada Node Address (3) Scada Node Address (2) Scada Node Address (1) Scada Node Address (0), LSB Each of these settings is displayed as follows: An Alternating display showing "Addr" for 1 second then "AX Y" for 1 second. The X represents the place of the address digit displayed and will be either 4,3,2,1,0. The Y is a single digit representing the actual address digit and will be either 9,8,7,6,5,4,3,2,1,0. Please note the highest possible address is thus the MSB will not increase beyond 6. It is your responsibility to make sure the address you set in is at or below For example: You would like to change the Node Address from the default setting of 4 to When the display is alternating between "Addr" and "A4 0" you would press the EQ switch and increase the setting until the display showed an alternating "Addr" and A4 1". When the display is alternating between "Addr" and "A3 0" you would press the EQ switch and increase the setting until the display showed an alternating "Addr" and A3 2". When the display is alternating between "Addr" and "A2 0" you would press the EQ switch and increase the setting until the display showed an alternating "Addr" and "A2 3". When the display is alternating between "Addr" and A1 0" you would press the EQ switch and increase the setting until the display showed an alternating "Addr" and A1 1". When the display is alternating between "Addr" and "A0 0" you would press the SELECT switch and decrease the setting until the display showed an alternating "Addr" and A0 0". The Node Address is now set to To advance to the next setting you must press the HVSD Reset Button. Page 4 of 26

5 Setting the Scada Comm Port The communications card is equipped with 3 methods of communicating, RS232, RS485 and TCP. NOTE: THIS SETTING IS SKIPPED IF YOU SELECT MODBUS TCP AS THE PROTOCOL. The following setting is used to set the Scada Comm Port: Scada Comm Port Each Comm Port setting is displayed using an alternating "POrt" for 1 second followed by either " 232", " 485" or " tcp". To change the Comm Port from RS232 to RS485, press the EQ switch "UP" until the display shows an alternating "POrt" followed by " 485". To change the Comm Port from RS232 to TCP, press the EQ switch "UP" until the display shows an alternating "POrt" followed by " tcp". To advance to the next setting you must press the HVSD Reset Button. Setting the Scada Baud Rate NOTE: THIS SETTING IS SKIPPED IF THE SELECTED COMM PORT IS TCP. The communications Card may be set to communicate over an RS232 or RS485 network at the following Baud Rates: 1200, 4800, 9600 The following setting is used to set the Baud Rate: Scada Baud Rate Each Baud Rate setting is displayed using an alternating "baud" followed by the baud rate "XXXX". To change the baud rate, press the EQ switch "UP" and increase the setting until the desired baud rate is shown. For example: to set the baud rate at 1200, hold the switch "Down" until the display shows "baud" and "1200", then release the switch. To advance to the next setting you must press the HVSD Reset Button. Setting the Scada IP Address NOTE: THIS SETTING WILL NOT APPEAR IN THE SEQUENCE IF THE COMMUNICATION PORT HAS BEEN SET TO RS232 OR RS485. The IP address in quad format is defined as follows Q3.Q2.Q1.Q0 where Q3, Q2, Q1 and Q0 may be represented by a 1 to 3 digit number thus the default IP of may be broken down as follows; Q3=192, Q2=168, Q1=0, Q0=6. The following settings are used to set the IP Address: Scada IP Address Quad 3, Q3 Scada IP Address Quad 2, Q2 Scada IP Address Quad 1, Q1 Scada IP Address Quad 0, Q0 Page 5 of 26

6 Each of these settings is displayed as follows: An Alternating display showing "IP X" for 1 second then a 1 to 3 digit number. The X will be either 3,2,1 or 0 and tells you which quad is being shown. The 1 to 3 digit number is the setting for that quad. For example: You would like to change the IP Address from the default setting of to When the display is alternating between "IP 3" and " 192" you would press the SELECT switch and decrease the setting until the display showed an alternating "IP 3" and 190. When the display is alternating between "IP 2" and " 168" you would press the SELECT switch and decrease the setting until the display showed an alternating "IP 2" and 160 ". When the display is alternating between "IP 1" and " 0" you would press the EQ switch and increase the setting until the display showed an alternating "IP 1" and " 10". When the display is alternating between "IP 0" and 6" you would press the SELECT and decrease the setting until the display showed an alternating "IP 0" and 3". The IP Address is now set to To advance to the next setting you must press the HVSD Reset Button. Setting the Scada Netmask NOTE: THIS SETTING WILL NOT APPEAR IN THE SEQUENCE IF THE COMMUNICATION PORT HAS BEEN SET TO RS232 OR RS485. The Netmask like the IP Address discussed above is defined as follows Q3.Q2.Q1.Q0 where Q3, Q2, Q1 and Q0 may be represented by a 1 to 3 digit number thus the default Netmask of may be broken down as follows; Q3=255, Q2=255, Q1=255, Q0=0. The following settings are used to set the Netmask: Scada Netmask Quad 3, Q3 Scada Netmask Quad 2, Q2 Scada Netmask Quad 1, Q1 Scada Netmask Quad 0, Q0 Each of these settings is displayed as follows: An Alternating display showing "Sn X" for 1 second then a 1 to 3 digit number. The X will be either 3,2,1 or 0 and tells you which quad is being shown. The 1 to 3 digit number is the setting for that quad. For example: You would like to change the netmask from the default setting of to When the display is alternating between "Sn 3" and " 255" you do nothing and wait for the cal sequence to auto advance. When the display is alternating between "Sn 2" and " 255" you do nothing and wait for the cal sequence to auto advance. When the display is alternating between "Sn 1" and " 255" you would press the SELECT switch and decrease the setting until the display showed an alternating "Sn 1" and 0. When the display is alternating between Sn 0 and 0 you would do nothing. Page 6 of 26

7 The Netmask is now set to To advance to the next setting you must press the HVSD Reset Button. Setting the Scada Gateway NOTE: THIS SETTING WILL NOT APPEAR IN THE SEQUENCE IF THE COMMUNICATION PORT HAS BEEN SET TO RS232 OR RS485. The Gateway like the IP Address discussed above is defined as follows Q3.Q2.Q1.Q0 where Q3, Q2, Q1 and Q0 may be represented by a 1 to 3 digit number thus the default Netmask of may be broken down as follows; Q3=000, Q2=000, Q1=000, Q0=000. NOTE: A Gateway setting of is equivalent to not having a Gateway Setting. Thus if you are not sure if you need to set the Gateway then leave it at the default of The following settings are used to set the Gateway: Scada Gateway Quad 3, Q3 Scada Gateway Quad 2, Q2 Scada Gateway Quad 1, Q1 Scada Gateway Quad 0, Q0 Each of these settings is displayed as follows: An Alternating display showing "rs X" for 1 second then a 1 to 3 digit number. The X will be either 3,2,1 or 0 and tells you which quad is being shown. The 1 to 3 digit number is the setting for that quad. For example: You would like to change the gateway from the default setting of to When the display is alternating between "rs 3" and " 0" you would press the EQ switch and increase the setting until the display showed an alternating "rs 3" and 192. When the display is alternating between "rs 2" and " 0" you would press the EQ switch and increase the setting until the display showed an alternating "rs 2" and 168. When the display is alternating between "rs 1" and " to auto advance. 0" you do nothing and wait for the cal sequence When the display is alternating between "rs 0" and " 0" you would press the EQ switch and increase the setting until the display showed an alternating "Sn 0" and 11. The Gateway is now set to To advance to the next setting you must press the HVSD Reset Button. Setting the Scada Diagnostics Mode This setting when set to YES places the communications card into a mode where it is then possible to utilize a program such a hyperterminal to check communications. This capability has been added in recognition that not all installers will have a software program capable of simulating a master station with the selected protocol. The default selection for this setting is NO (displayed as no). Setting this to YES places the communications card into a mode where you can confirm communications using hyperterminal. In this mode the communication board will send out an ascii character message that says Press a key The characters will be sent out using communications parameters you have entered. When you see this message you are confirming that the communications card is capable of transmitting Page 7 of 26

8 on the port using the settings you have selected. When you press a key the communications card will reply saying You pressed the X key where X is the key you pressed. If you see this then the card is transmitting and receiving properly. PLEASE NOTE YOU MUST RETURN TO THE CAL SEQUENCE TO DEACTIVATE THIS MODE OR RESET THE CONTROLLER CARD. To advance to the next setting you must press the HVSD Reset Button At this point the controller card will exit the calibration sequence and return to normal operation. Page 8 of 26

9 RS232 Port Connection RS232, RS485 & TCP Connection Information RS232 communications are accomplished through J2. The RS232 Port is a galvanically isolated interface. The RS232 interface is configured as DTE. The default settings are 9600 baud, 8 Bits, No Parity, 1 stop bit and no flow control. Page 9 of 26

10 RS485 Port Connection (s) For RJ11/Phone Jack Equipped Cards The RS485 (J3, J4) ports are parallel RJ11 jacks. Thus you may connect to either J3 or J4. The RS485 Ports are galvanically isolated. The RS485 interface is "two wire" thus no handshaking takes place. The default connection would be 9600 baud, 8 Bits, No Parity, 1 stop bit and no flow control. The RS485 interface may require configuration of jumpers JP1/JP2, JP3/JP4, JP5/JP6 on the P60-302S card. JP1/JP2, JP3/JP4 serve as biasing loads. JP5/JP6 serve as a terminating load. Each jumper is marked with RIN (the jumper position places the load resistor in the circuit) or ROUT (the jumper position places the load resistor out of the circuit). The positioning of these jumpers will depend on the configuration of your RS485 network. Typically a network using a device like B&B Electronics RS232 to RS485 converter (Part Number 485SD9RJ) would not require the use of the biasing load resistors thus the jumpers configuration for JP1/JP2 & JP3/JP4 would be to position the shorting jumpers on JP1 and JP3 for all P60-302S cards placed on this network. If you do not have these biasing resistors already somewhere on the RS485 network then you will need to place the shorting jumpers on JP2 and JP4, JP5/JP6 will need to be placed on JP6 for P60-302S's that are in the first and last position on the RS485 network. The B&B device I have mentioned above does not provide a terminating resistor. The RS485 jacks on the P60-302S board are 6 position RJ11 jacks. Only positions 2,4,5 have connections. Pin 2 is Data A (-), Pin 5 is Data B (+) and Pin 4 is the Signal Ground. RJ11 jacks are configured such that when you face them (looking into the jack) Pin 1 is left most position and Pin 6 is the right most. For good signal quality it is advisable to use shielded twisted pair cable in your RS485 network (B&B Electronics, Part Number ETC8504 or ETC8505). Page 10 of 26

11 RS485 Port Connection (s) for Terminal Strip Equipped Cards The RS485 (TS1) port is a 3 pin terminal strip. The RS485 Ports are galvanically isolated. The RS485 interface is "two wire" thus no handshaking takes place. The default connection would be 9600 baud, 8 Bits, No Parity, 1 stop bit and no flow control. The RS485 interface may require configuration of jumpers JP1/JP2, JP3/JP4, JP5/JP6 on the P60-302S card. JP1/JP2, JP3/JP4 serve as biasing loads. JP5/JP6 serves as a terminating load. Each jumper is marked with RIN (the jumper position places the load resistor in the circuit) or ROUT (the jumper position places the load resistor out of the circuit). The positioning of these jumpers will depend on the configuration of your RS485 network. Typically a network using a device like B&B Electronics RS232 to RS485 converter (Part Number 485SD9TB) would not require the use of the biasing load resistors thus the jumper s configuration for JP1/JP2 & JP3/JP4 would be to position the shorting jumpers on JP1 and JP3 for all P60-302S cards placed on this network. If you do not have these biasing resistors already somewhere on the RS485 network then you will need to place the shorting jumpers on JP2 and JP4, JP5/JP6 will need to be placed on JP6 for P60-302S's that are in the first and last position on the RS485 network. The B&B device I have mentioned above does not provide a terminating resistor. The RS485 jacks on the P60-302S board is a 3 position terminal strip. Pin 1 is Data A (+), Pin 3 is Data B (-) and Pin 2 is the Signal Ground. The terminal strip is positioned such that when you face it (looking directly into the strip) Pin 1 is the left most position and Pin 3 is the right most. For good signal quality it is advisable to use shielded twisted pair cable in your RS485 network (B&B Electronics, Part Number ETC8504 or ETC8505). Page 11 of 26

12 TCP Port Connection The TCP Interface will require the use of a Cross-over cable if you are going to connect the P36-302S card directly to a NIC on a PC. If you connect through a hub a straight through cable should suffice. The Ethernet Port on the P60-302S is 10/100 Base-T compatible. The TCP Connection is accomplished through a single RJ45 jack that is mounted to a daughter board on the P60-302S. Page 12 of 26

22 La Marche Communications Board Troubleshooting Guide 1) Verify operation of RED LED on 302S Board. The communications board (ECN and above) are equipped with a Red LED (LED1). This LED indicates the following: OFF: The board is not being powered or has failed. Check to see the cable is properly connected to the 3-pin connector J5 on the communications card. FLASHING: A problem with communications between the 302S and the 205T has occurred. If the charger is equipped with a 205T check to see if the 10-pin ribbon cable is connecting J1 (Slave Port) on the 302S is connected to J2 on the 205T. A flashing LED can indicate the cable is bad. This LED will also flash when the 205T are in either the Factory or Customer calibration modes. ON: This indicates the 302S and 205T are communicating properly. 2) Confirm proper configuration of 302S card for customer s application. The 302S card is shipped with the following default settings: Comm Port: RS232 (J2) Baud Rate: 9600 Data Bits: 8 Stop Bit: 1 Parity: None Flow Control: None Node Address: These settings may not be what are desired and the only way to change them is to enter the customer calibration routine. The settings displayed in the customer cal routine should be checked to make sure they coincide with the customer s application. 3) Confirm the correct type of cable is connecting the 302S to the customer s application. Refer to LaMarche 302S Cabling Guide Section in the 302S Card Manual for details. 4) Is the 302S card being used on an RS485 Network? For an RS485 Network to function properly it must be properly biased and terminated. The 302S card is equipped with 3 configuration jumpers. JP5 removes the termination resistor. JP6 adds in the termination resistor. JP1 & JP3 remove the biasing resistors. JP4 & JP6 add in the biasing resistors. Common practice with RS485 networks is to configure the last device in a network (the device furthest from the master) with a termination resistor and the device closest to the master or sometimes the master has the biasing resistors. Problems often occur when devices are added and removed from a RS485 network without reconfiguring/checking the termination and biasing resistor arrangement. 5) Testing Method. The 302S cards are tested at the LaMarche factory prior to shipment using the Triangle MicroWorks Test Harness software program. Each of the ports (RS232, RS485 and Ethernet) is tested. The next several pages show actual screenshots from a DNP Session that may assist in troubleshooting as they depict the actual settings that were required to test the board. Page 22 of 26
