5 Introduction This document defines the electrical interface, serial data format, and communication protocol of the Serial Communication Control Interface. The purpose of this interface is to enable a computer application to control one or more units. Units refer to either displays or panel computers. Serial Interface Configuration The serial interface can have different configurations, selected by the OSD menu. The configurations are defined as follows: RS wire RS-485/RS-422 One computer controls one unit, no individual address One computer controls max 16 units, each with individual address. 2-wire RS-485 One computer controls max 16 units, each with individual address. Cables A cable with an overall shield terminated at the back shell should be used. Electrical Interface Electrical signals shall conform to RS-485, RS-422 or RS-232. Only Receive Data, Transmit Data, and Signal Ground are used. The same conditions apply for both 4-wire and 2-wire, and will just be referred to as RS-485 in this document. Hardware handshake is only supported by loopback handshake for RS Display (Maritime Multi Display - MMD) based units with Multifunction Cable (VSD series): SCOM RS-232 : 1 x 9P DSUB (female) COM1 RS232 SCOM RS-422/485 : Multifunction Cable customized/optional on request IND

8 Data Rates The unit is configured to transmit and receive data at 9600 bits/second (Serial mode) Data Format Serial Mode Data shall be transmitted with no parity, 8 data bits, one start bit and one stop bit. Message Format The basic message format shall be as follows: Byte # , etc 8 or 7+DATA=END ATTN ADDR CMD CMD CMD LEN IHCHK DATA IDCHK The minimum message size is 7 bytes (0x07). The maximum message size is 82 bytes (0x52), consistent with the EN standard. Colors will be used throughout this manual to indicate byte positions. Every byte sent are viewed in this document as HEX values and are based on standard characters in the ASCII table (0 to 255) to send or receive messages in a human readable input/output. No further decoding or decrypting functionality is needed or required. Every command sent and received should always end with a 0x00 (null byte terminator). ATTN Attention (ATTN) This single byte is used to identify a start of message. 3 values are possible: ATTN 0x07 0x06 0x15 Description Command, also known as ASCII BELL Acknowledge, also known as ASCII ACK Negative Acknowledge, also known as ASCII NAK A device shall send a command using the 0x07 Attention Code. The unit will respond to the command with either an ACK if the command completed successfully, or a NAK if the command failed. NOTE: A complete HEX, ASCII, BIN and Character table overview are available in the APPENDIX chapter. ADDR Address (ADDR) This single byte is used to specify a particular unit to receive a Command and to identify the unit responding (ACK or NAK) to a Command. All units will support the broadcast address. The factory default adress is 0x00, while in this manual illustrated throughout as 0xFF. The Address field shall have the following values: ADDR 0xFF 0x00 to 0x0F Description Broadcast - Addressed to all units Address of a specific unit, 0 to 15 (max 16 units) 8

9 CMD Message Commands and Queries (CMD) Contents The command can be one of the following values and consists always of 3 bytes in positions 2,3,4: Byte 2 Byte 3 Byte 4 ASCII Description I/O Page 0x42 0x52 0x49 "BRI" Backlight Minimum Value (*3) W 11 0x42 0x52 0x54 "BRT" User Brightness Control W 11 0x42 0x5A 0x5A "BZZ" Buzzer Control W 12 0x45 0x54 0x43 "ETC" Elapsed Time Counter Query R 12 0x44 0x4C 0x4E "DLN" Query available ECDIS packages (*2) R 13 0x44 0x4C 0x3F "DL?"

(*2) "DL?/DLN" = Command not available on units manufactured before May (*3) "BRI" = Command not available on units manufactured before October

10 LEN Data Length (LEN) This single byte defines the length of DATA in the message in bytes. The maximum value for this field is 74 bytes (0x4A in HEX). The minimum value is 0 bytes (0x00 in HEX). IHCHK Inverse Header Checksum (IHCHK) This single byte is a simple 8-bit checksum of the header data, message bytes 0 to 5 on which a bit-wise inversion has been performed. The checksum shall be initialised to 0. The 8-bit sum (without carry) of bytes 0, 1, 2, 3, 4, 5 and 6 shall be 0xFF (255 in value). If the unit receives a message with an incorrect checksum, the unit will reply with the attention code set to NAK and no data field. This does not apply to Broadcast messages in RS-485 mode, in which case there will be no reply. DATA Data Field (DATA) The single byte is the DATA field which shall only be transmitted if LEN is greater than 0. This field depends on the CMD transmitted. IDCHK Inverse Data Checksum (IDCHK) This single byte shall only be transmitted if LEN is greater than 0. This is a simple 8-bit checksum of the data field, message bytes 7 to 7+(LEN-1) on which a bit-wise inversion has been performed. The checksum shall be initialised to 0. The 8-bit sum (without carry) of bytes 7 through 7+LEN inclusive shall be 0xFF. The receiver will reply to any message that the checksum has failed with the attention code set to NAK. This requirement does not reply to broadcast messages in RS-485 (for units that support it) mode, in which case there will be no reply. Basically this byte is located at the very end of a received stream. NOTE: A complete HEX, ASCII, BIN and Character table overview are available in the APPENDIX chapter. 10

11 "BRI" - Backlight Minimum Value Set the backlight minimum value. Range from 0x00 to 0xFF (0% - 100%). Command to set 50% Brightness: 0x07 0xFF 0x42 0x52 0x49 0x01 0x1B 0x80 0x7F *Note: Command NOT available for JH 22T11 xxd-xxx-xxxx - 22 inch and HM 19T14 MMD-AAT-AOBA - 19 inch models. BRT - User Brightness Control This command is sent to the unit to command the backlight brightness control setting.the brightness value shall be sent as one byte in the DATA field. A setting of 0x00 will indicate off. A setting of 0xFF (255 in value) will indicate maximum brightness. Intermediate values will control brightness over the range from minimum to maximum luminance. LEN = one data byte. After any power cycle the BRT will be set to 100%. If the data checksum is valid and the brightness was set, the unit will reply to this command with an ACK attention code. The DATA field in the reply shall indicate the resulting brightness control setting. If an invalid checksum was received and the message was not Broadcast and RS-485, the unit will reply with an NAK attention code. The DATA field in the reply will indicate the current brightness control setting. If BRT is 100%, the user can adjust the brightness from 0-100%. If the BRT is set to 60%, the visual brightness is set to 60%. The user can adjust the brightness from 0-100% within the 60% set by BRT. If the user sets the potensiometer to half, the visual brightness will be 30% (half of 60%). If BRT is set back to 100%, the visual brightness will be 50% (half of 100%). Command to set 60% Brightness: 0x07 0xFF 0x42 0x52 0x54 0x01 0x10 0x99 0x66 Acknowledge was set to 60% Brightness: 0x06 0xFF 0x42 0x52 0x54 0x01 0x11 0x99 0x66 Negative Acknowledge 40% Brightness: 0x15 0xFF 0x42 0x52 0x54 0x01 0x02 0x66 0x99 11

12 BZZ - Buzzer Control This command is sent to the unit to control buzzer on/off if there is a buzzer present. LEN = one data byte. 0x00 0xFF Turn the buzzer off Turn the buzzer on If the data checksum is valid, the unit will reply to this command with an ACK attention code. The DATA field will indicate the buzzer state. If an invalid data checksum was received and the message was not broadcast and RS-485, the unit will reply with a NAK attention code and the current control setting. Command to set Buzzer Enable: 0xFF 0x07 0xFF 0x42 0x5A 0x5A 0x01 0x02 0xFF 0x00 Acknowledge Buzzer status was set to Enable: 0xFF 0x06 0xFF 0x42 0x5A 0x5A 0x01 0x03 0xFF 0x00 ETC - Elapsed Time Counter Query The unit features an elapsed time counter which counts the total number of hours that the unit has been operated. No data shall be sent with this command. The unit will reply to this command with an ACK attention code. The DATA field will be set to a 3 byte string, where the most significant byte is transmitted first. The ETC has a limit on maximum hours (defined into 5 bytes, numbers 0 to 9 each), equivalent to 11 years. If this number is reached, the ETC will stop counting, and the ETC command will always reply with maximum number of hours (99999). Command to Query ETC: 0x07 0xFF 0x45 0x54 0x43 0x00 0x1D Acknowledge = (combined or 58 hours): 0x06 0xFF 0x45 0x54 0x43 0x05 0x19 0x30 0x30 0x30 0x35 0x38 0x02 The ETC value has been hardcoded to 5 bytes, prefixed with 0. 12

13 "DLN" - Download ECDIS package table x Before send this command, use "DL?" to get there are how many available packets in each ECDIS table, like "DL?" command, if we at Calibration VGA mode the ACK is data in VGA table, and also at DVI mode. We can not use this command at No Calibration. Every packet has a head (Byte 7 and Byte 8), Byte 7 is this packet number and Byte 8 is "-" with ASCII, and follow Bytes are data.(without last byte, it is checksum for data. If packet is full the data is Byte 9 to Byte 38).

Each calibration mode is separate. If we at Calibration VGA mode, we will get the available packets number at VGA table, and also on Calibration DVI. But there is no available packet at No Calibration. Packets = Size of Table / 32 bytes per packet Command to read package #3: 0x07 0xFF 0x44 0x4C 0x3F 0x00 0x2A Acknowledge: DL? 3 available packets: 0x06 0xFF 0x44 0x4C 0x3F 0x01 0x2A 0x03 0xFC 13

14 DST - Display State This command is sent to the unit to control the unit on/off or query the on/off state of the unit. LEN = one data byte. NOTE: This command is available from version SW G09 and upwards. 0x00 0xFF 0x3F Turn the unit off Turn the unit on? - Query the state of the unit. The returned DATA field will indicate the state. 0x00 = Unit is off. 0xFF = Unit is on. If the data checksum is valid, the unit will reply to this command with an ACK attention code. The DATA field will indicate the unit sate. If an invalid data checksum was received and the message was not broadcast and RS-485, the unit will reply with a NAK attention code and the current state. Query Display State: 0x07 0xFF 0x44 0x53 0x54 0x01 0x0D 0x3F 0xC0 Acknowledge Display state, unit is on: 0x06 0xFF 0x44 0x53 0x54 0x01 0x0E 0xFF 0x00 Acknowledge Display state, unit is off: 0x06 0xFF 0x44 0x53 0x54 0x01 0x0E 0x00 0xFF MAN - Manufacturer ID This command is sent to the unit to request Manufacturer ID.

18 MCC - OSD Control Functionality This command gives remote access to the unit s OSD menu settings. The commands are transmitted in the DATA field. For future products, it can not be guaranteed that all commands will still be available. If the checksum is valid, the unit will reply to this command with an ACK attention code, where the data field contains the original MCC command followed by acknowledge from the controller. If the checksum is invalid and the message was not broadcasted, and if RS-485, the unit will reply to this command with a NAK attention code, where the data field contains the original command. It is expected that you already have knowledge on how to send, receive and interpret the commands by having studied the examples prior to the MCC command table below. The list below is a compressed version of the HEX values you need to send and will apply to all units (ADDR set as FF ). For readability the prefix 0x has been removed in the table and seen as a complete HEX string as values from 00 to FF (2 by 2 letters). Every command will contain the MCC (0x4D, 0x43, 0x43) ASCII letters as default indicator. The functional byte positions in the table below are indicated with Red Color. The counting of values (xx,yy) should always be sent as HEX, not numerical values, which means 64 is not 64 in numerical, but rather 100 as numerical. The single byte that represent MCC Command ID is marked with Green Color. The checksum is marked with Blue Color. The other byte positions in Black Color are defined as in the Message Format seen in the beginning of this chapter.

Note that this feature is only available when using the Unit OSD Control MCC command. This command is a write command which will change the current value. 25

26 Operational Requirements The following sections define the operational requirements. Serial Message Failure If serial messages stop being transmitted or are corrupt, the unit will remain at the last commanded brightness. Periodic Messages The Brightness Command shall be transmitted to the unit at a repetition no faster than 4 Hz. Keep-alive Alarm The VER query can be used for keep-alive alarm logic in the application software on the computer. It is recommended to limit this function to one query per second. Individually Addressed Command Response Time The unit will output the required response within Tr = 2.5 character periods after the last byte of a command message is received (2.6ms at 9600 bit/sec), except as specified herein.. Broadcast Command Response Time In response to Serial mode RS-485 broadcast command messages, after the last byte of the command message is received, all units will reply within the time period defined for Te, below. Further more, any gap between these individual responses will be less than the Intermessage Gap, defined below: Te = (Tr + Lr) * N, where Lr = length of the ACK/NAK message response Tr = response time N = the total number of units* *) As the units reply in order to their address, the units must be given subsequent addresses, starting at zero, for N to equal the total number of units. If not, N = the highest unit address + 1. The maximum Lr for a selected command set are shown in the table below: Command BRT BZZ ETC DST MAN POT SNB SWI TMP TYP VER MCC Lr xx For the BRT command, and 8 units, this corresponds to Te = (2.5 * * 10) * 8 / 9600 = 95.8 ms Intermessage Gap - Serial Mode Following an individually addressed command, the next command shall not be issued until at least Tg = 5 character periods after the ACK or NAK message received. At 9600, that is 5 * 10 / 9600 = 5.2ms. Following the issue of a broadcast command message, the next command shall not be issued until at least Tc = Te + Tg, where Te is as defined for Broadcast Command response and Tg is defined above. 26

27 Unit Response and Addresses When individual unit addressing is supported by an installed configuration of units in a RS-485 (for units that support it) system, a separate ACK or NAK message for each unit will be transmitted providing each unit s individual address in response to any broadcast addressed Command. NAK messages will not be generated when an error in a Broadcast message is detected. When individual unit addressing is not supported, the unit will only respond to the broadcast address and will include the broadcast address in the ACK and NAK messages. NAK messages will not be generated when an error in a Broadcast message is detected. When a unit receives an incomplete message and the next byte is not received until after a time equal to the Intermessage Gap, the next bytes received shall be processed to check for the start of a new command (0x07, ASCII Bell). If the header checksum is valid, but the first byte of the command message is not 0x07, as specified, the unit may wait until after the next inter-message gap to resume checking. A NAK message shall not be generated. If the header checksum is valid, but the value of the CMD field does not equal one of the defined commands, the unit shall reply by generating a NAK message as though a VER command had been received. If the header checksum is valid, but the value of the LEN field is greater than the maximum allowed, the unit shall ignore the message. A NAK message shall not be generated. If the data checksum is valid, but the value in the DATA field associated with a command is invalid (out of range, undefined, etc.), the unit shall generate a NAK message indicating the current data value in the DATA field. Additional Commands In time, additional commands and corresponding data fields may be defined. These additions will not conflict with the operation of the interface as defined herein in this document. 27
