4 RS485 SLAVE OPTIONS RS485 SLAVE OPTIONS There are three (3) wiring options available for the JACQUES RS485 Slave, and must be quoted when ordering them. The options are: 1) RS485 SLAVE OPTION 1: (page 5) The Slave comes with two on-board Combicon connectors (J14, J15). These connectors allow connection to two Auxiliary Audio Channels. 2) RS485 SLAVE OPTION 2: (page 5) The Slave comes with two on-board Combicon connectors (J14, J15). These connectors allow connection to two Auxiliary Audio Channels, as well as the provision for the Microphone Output audio signal. 3) RS485 SLAVE OPTION 3: (page 10) The Slave comes with one on-board Combicon connector (J14). It does not have the facility for Auxiliary Audio Channels or Microphone Output audio signal. Power is supplied to the Slave via this one connector. 4

5 Connections WIRING (OPTIONS 1 and 2) The JACQUES RS485 Slaves are connected directly to a separate JACQUES Controller, or daisy-chained to another RS485 Slave. Figure 1 shows the wiring connections from the RS485 Slave, using the two PCB connectors (J14, J15). Figure 1: Connection diagram from the RS485 Slave using J14, J15. Note #1: Cat-5, 4-pair data cable This Cat-5 cable can either be: Star-Wired directly into the Slave Port of a JACQUES Controller Daisy-Chained wired into another RS485 Slave, which eventually is connected back into the Slave Port of a JACQUES Controller! The Green/White and Green pair is not used. A maximum of up to 32, RS485 Slaves can be wired on a single data run. Any more than 32 Slaves, requires additional JACQUES Repeaters to be added to the system. continued 5

6 Note #2: Single-pair shielded cable (Refer to Figure 1, previous page) This cable is only connected when the Microphone Output is used, (on the RS485 SLAVE OPTION 2). The Microphone Output is a feature of the RS485 Slaves, which is ONLY available as a factory option (OPTION 2) and must be specified when ordering. If Microphone Output is used, this cable is Star-Wired directly wired into an Audio Recorder or Audio Monitoring Device. (Refer to Figure 3)! The Microphone Ground Shield should be connected at the Audio Recording Device only.! The Microphone Output cables are NOT to be wired into a Controller. Note #3: Fig-8 cable This Fig-8 type cable is specifically used for wiring up the Slave s power supply cables (+ve 20V DC, Ground). The cross sectional area of the cable used depends on the total number of Slaves used and the length of the cable run. The longer the cable run, the larger the cross-sectional area of the Fig-8 cable must be. (Refer to Table 3, Page 14 for specifications on power-supply cable area) This Fig-8 power supply cable can either be: Star-Wired directly into the 20V DC power-supply connections Daisy-Chained wired into another RS485 Slave, which eventually is connected back into the 20V DC power-supply connections Note #4: 2-pair shielded audio cable This cable is used for the distribution of the two Auxiliary Audio Channels (Aux Audio Ch#1, Aux Audio Ch#2). Only 2-pair type shielded audio cable is used Do not use Cat-5 type cable. It makes servicing a lot easier with 1x Cat-5 and 1x Audio cable, rather than having 2x Cat-5 cables. This 2-pair shielded audio cable can either be: Star-Wired directly into the Slave Port of a JACQUES Controller Daisy-Chained wired into another RS485 Slave, which originated from the Slave Port of a JACQUES Controller 6

7 Wiring Diagram The following Figure 2 shows the wiring diagram of the cables from the RS485 Slave to the Concentrator, using the two PCB connectors (J14 and J15).! The Audio Shield is not connected at the Slave, but is connected to the 0V at the Controller end. These shields need to be connected through if Daisy-Chained. Figure 2: Connection wiring diagram: RS485 Slave to a Controller Slave Port, using J14, J15. 7

8 Wiring Table The following Table 1 shows the pin-to-pin cable wiring of the RS485 Slave to Controller Slave Port connections, using the two PCB connectors (J14, J15).

9 Auxiliary Audio Channels The Auxiliary Audio Channels (Aux Audio CH#1, Aux Audio Ch#2) are wired using 2- pair shielded audio cable, with the following colour codes: Use Blue and Blue/White colours for Channel #1 Use Orange and Orange/White for Channel #2! The Audio Shield is not connected at the Slave, but is connected to the 0V at the Controller end. These shields need to be connected through if Daisy-Chained. Microphone Output (OPTION 2 only) Refer to Figure 3. The Microphone Output is only available as a feature on the RS485 Slaves OPTION 2 and must be specified when ordering. If using an OPTION 2 board, the Microphone Outputs can be directly wired into an external Audio Recorder or Monitoring device. This allows direct monitoring of the call Send and Receive conversations. Note that the output signal is a Balanced Audio, Line-Level output. Figure 3: Block diagram of Microphone Output connector. 9

10 WIRING (OPTION 3) Connections The JACQUES RS485 Slaves are connected directly to a separate JACQUES Controller, or daisy-chained to another RS485 Slave. Figure 4 shows the wiring connections from the RS485 Slave, using the one PCB connector (J14). Figure 4: Connection diagram from the RS485 Slave, using J14 only. Note #1: Cat-5, 4-twisted pair cable This Cat-5 cable can either be: Star-Wired directly into the Slave Port of a JACQUES Controller Daisy-Chained wired into another RS485 Slave, which eventually is connected back into the Slave Port of a JACQUES Controller! The Green/White and Green pair is not used. A maximum of up to 32, RS485 Slaves can be wired on a single data run. Any more than 32 Slaves, requires additional JACQUES Repeaters to be added to the system. continued 10

The cross sectional area of the cable used depends on the total number of Slaves used and the length of the cable run. The longer the cable run, the larger the crosssectional area of the Fig-8 cable must be. (Refer to Table 3, page 14 for specifications on power-supply cable area) This Fig-8 power-supply cable can either be: Star-Wired directly into the 20V DC power-supply connections Daisy-Chained wired into another RS485 Slave, which eventually is connected back into the 20V DC power-supply connections 11

14 Power Supply Wiring (All OPTIONS) Power Supply Wiring When wiring up the JACQUES RS485 Slaves, be sure to use the correct Fig-8 cable, cross-sectional area for the power-supply cable run. The Slave power-supply cable cross sectional area depends on the total number of Slaves used and the total length of the cable. The following Table 3 shows the cross sectional area of the cable than needs to be used in number/length situations. Table 3: Power-supply cable type used with the RS485 Slaves. TOTAL NUMBER OF RS485 SLAVES USED TOTAL CABLE LENGTH (IN METRES) to 3 4 to 7 8 to to to mm sq. 2.5mm sq. 2.5mm sq. 2.5mm sq. 14

15 Configuration (All OPTIONS) DIP Switch settings Each individual RS485 Slave requires it to have a specific Address identifier number. It is used to identify itself to the rest of the system. The Address number is set by the DIP Switches (Figure 4), found on the board of the RS485 Slaves. Refer to Table 3 for value details. The Address number can be a number between (and including) 1 and 255. The number is coded using the Binary number system. Figure 4: Location of the DIP switches on the Slave PCB. See over (Table 4) for DIP Switch values and settings. 15

16 DIP Switch Table The DIP Switches (SW1) are used to set an Address number between (and including) 1 and 255. The Address values are set up using the Binary number system.
