Serial Communication (SCOM) Interface 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.
Serial Communication (SCOM) Interface Pinout Assignments Pin Assignments - Multifunction Cable Outputs For Display Units (MMD/STD w/Multifunction Cable - RS-232). Connectors that are commonly available on the Multifunction Cable or customized cable. Connectors are seen from users Point Of View (POV).

Serial Communication (SCOM) Interface 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 # 0 1 2 3 4 5 6 7, etc 8 or 7+DATA=END ATTN ADDR CMD CMD CMD LEN IHCHK DATA IDCHK The minimum message size is 7 bytes (0x07).
Serial Communication (SCOM) Interface 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 Unit Type Page 0x42 0x52 0x54 "BRT" User Brightness Control W all 0x42 0x5A 0x5A "BZZ" Buzzer Control W all 11 0x45 0x54 0x43 "ETC" Elapsed Time Counter Query R all 12 0x44 0x4C 0x4E "DLN" Query available ECDIS packages R xxD 12 0x44 0x4C 0x3F "
Serial Communication (SCOM) Interface 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.
Serial Communication (SCOM) Interface “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%.
Serial Communication (SCOM) Interface “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 99999 hours (defined into 5 bytes, numbers 0 to 9 each), equivalent to 11 years.
Serial Communication (SCOM) Interface "DL?" - Query available ECDIS packages This command is ask the unit to return there are how many packets in ECDIS table available for download. 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’.
Serial Communication (SCOM) Interface “MAN” - Manufacturer ID This command is sent to the unit to request Manufacturer ID. No data shall be sent with this command. The unit will reply to this command with an ACK attention code. The DATA field indentify the manufacturer in a text string.
Serial Communication (SCOM) Interface “SNB” - Serial Number Query This query is sent to the unit in order to identify the unit serial number. No data shall be sent with this query. The unit will reply to this command with an ACK attention code. The DATA field will be set to an ASCII text string to indicate the specified Serial Number, e.g: “12345”. Note that the length of Serial Number is not limited to 5 characters.
Serial Communication (SCOM) Interface “TMP” - Temperature Sensor Query The unit features a sensor that measures the temperature inside. The unit will reply to this command with an ASCII string indication the temperature in Celcius degree (°C). 0x52 0x48 "R" = Read current temperature "H" = Read Temperature Histogram The histogram is a table for temperature -55 to 125 °C and be divided to 12 parts. The temperature range for each part is 16 °C and each part use two bytes.
Serial Communication (SCOM) Interface “VER” - Type/Model Number Query This query is sent to the unit in order to identify unit type by a preassigned code and establish the version of the serial communications interface software. No data shall be sent with this query. Any future revisions, such as additions or changes to the commands or data fields, shall increment the unit Version Number. The unit will reply to this command with an ACK attention code. The DATA field has a unique 1-byte unit model code.
Serial Communication (SCOM) Interface “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.

Serial Communication (SCOM) Interface 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.
Serial Communication (SCOM) Interface 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.
