Interface Configuration 1 Interface Configuration A command can be sent either using the serial interface (RS232 or RS485) or the Ethernet interface via UDP.
Ethernet Communication 2 Ethernet Communication In addition to serial communication via the built-in RS232- and RS485 interfaces, Lauer Navigation Monitors also support Ethernet communication for remote controlling, device configuration and firmware update. For a wide range of software support, the firmware includes standard network protocols such as TCP/IP, HTTP, UDP and WINS. The main communication channel uses UDP (User Datagram Protocol), which is a connectionless and simple protocol.
Ethernet Communication UDP UDP (User Datagram Protocol) is a connectionless protocol. SCOM messages are encapsulated within UDP, which allows sending and receiving them via Ethernet. Connectionless means that no individual destination address is specified. Instead, UDP packets are sent to the predefined broadcast address 255.255.255.255, at which any Lauer Navigation Monitor listens. Individual addressing is done in the upper protocol layers, such as SCOM and TCP/IP.
Ethernet Communication WINS WINS (Windows Internet Naming Service) allows a Lauer Navigation Monitor to register a unique name (host name) and map it to its IP-address. Once registered, the Lauer Navigation Monitor can be accessed using this configurable name, without the knowing its IP-address.
Message Format and Description 3 Message Format and Description A SCOM message is a stream of bytes, containing the destination, type of message and the corresponding data, if available. The complete stream is protected by two checksums. Data transfer is initiated by sending a command message. Depending on the command, a response message may be sent back. Some commands may contain sub-commands and data, which are sent in the data field of the message.
Message Format and Description Byte 5 Field LEN Value 0 to 74 (0x00 to 0x4A) Size 1 byte Description The size of the DATA-field in bytes. To protect the message header (bytes 0 to 5), a simple 8-bit checksum is calculated as follows: 6 ICHKH ... 1 byte 1. Calculate the sum of bytes 0 to 5. 2. Reduce the sum width to 8 bits (AND 0xFF). 3. Invert all bits. The result is ICHKH. The checksum is verified as follows: 1. Calculate the sum of bytes 0 to 6. 2. Reduce the sum width to 8 bits (AND 0xFF). 3.
Monitor Addressing 4 Monitor Addressing By default, a Lauer Navigation Monitor supports the standard SCOM addressing scheme, which allows a total count of 16 monitors within a network. The address of a monitor is set with four DIP switches. If a SCOM command is sent to a monitor, the ADR field must contain either the broadcast address 0xFF, or the address of the destination device set by the DIP switches. To eliminate this limit, a new addressing scheme is introduced first with Lauer Navigation Monitors.
Protocol Description and Timings 5 Protocol Description and Timings The protocol used for transferring SCOM messages and receiving response messages is optimized for easy software implementation. Regardless of the type of interface, a connected monitor is always passive and listening for a command to be received by any available communication interface. A monitor never sends SCOM messages by itself, unless it is configured as a remote controller.
Protocol Description and Timings Conditions for Response Message The conditions for a response message generated by the monitor are described below: Interface RS232 RS485 Ethernet Address condition Command status Response Address does not match monitor address not EXECUTED No response not EXECUTED No response Address matches monitor address if COMPLETED ACK if FAILED NAK Address is Broadcast address (0xFF) if COMPLETED ACK if FAILED NAK Address does not match monitor address not EXEC
Protocol Description and Timings The Lr value depends on the command, for which the response message is generated. Detailed information and the “Maximum Lr value” for each response message can be found in Command Reference chapter. Note: The given “Maximum Lr value” is specified for a valid command. If an invalid command with a data field exceeding the specification is sent, the Lr value will grow accordingly.
Command Reference 6 Command Reference The Lauer SCOM protocol exposes many commands for remote control of a Lauer Navigation Monitor by a dedicated software. It supports all standard SCOM commands, as well as the new Lauer command set for special purpose functions.
Command Reference 6.1 BRT Backlight Brightness Sets the backlight level to the given value. This command affects only the brightness of the backlight lamp or LED array, not the brightness value of the video controller. Supported since Firmware Version MT223 NAV-230G: 1.0 MT226 NAV-230G: 1.
Command Reference Maximum Lr for this Command 9 Example 1 Set the backlight level of monitor at address 0.7 (group 0, address 7) to 130 (0x82): 0 1 2 3 4 5 6 7 0x07 0x07 0x42 0x52 0x54 0x01 0x08 0x82 8 0x7D Monitor at address 0.7 (group 0, address 7) has acknowledged the new backlight level 130 (0x82): 0 1 2 3 4 5 6 7 0x06 0x07 0x42 0x52 0x54 0x01 0x09 0x82 8 0x7D Example 2 Send an invalid “BRT” command to the monitor at address 0.7 (group 0, address 7).
Command Reference 6.2 MAN Manufacturer ID Requests the manufacturer ID from the monitor. The manufacturer ID is a short, max. 7 character ASCII-string containing the manufacturer specific code. For monitors manufactured by Elektronik-Systeme Lauer GmbH & Co. KG, the returned code is always “LAU”. Supported since Firmware Version MT223 NAV-230G: 1.0 MT226 NAV-230G: 1.0-DSCALE2 Command Stream 0 1 0x07 ADR 2 0x4D 3 4 5 6 0x41 0x4E 0x00 ICHKH 5 6 7...
Command Reference 6.3 VER Unit ID and Model / Version Number Requests the preassigned unit ID and model code, and the version of the serial communications interface software. For compatibility reasons, this code is always static and does not return information specific to Lauer Navigation Monitors. To get device informations specific to Lauer Navigation Monitors, such as firmware version etc., use the Lauer Extension command “LAU”. Supported since Firmware Version MT223 NAV-230G: 1.0 MT226 NAV-230G: 1.
Command Reference 6.4 POT Local Control Enables or disables the local backlight level control. If the local backlight control is enabled, the backlight level can be changed using the front panel buttons and by remote control (serial or Ethernet interface, analog or digital input). If the local backlight control is disabled, the backlight level cannot be changed using the front panel buttons. It can be still changed by any remote control option. Supported since Firmware Version MT223 NAV-230G: 1.
Command Reference Maximum Lr for this Command 9 Example 1 Disable the local control of monitor at address 0.7 (group 0, address 7): 0 1 2 3 4 5 0x07 0x07 0x50 0x4F 0x54 0x01 6 0xFD 7 8 0x00 0xFF Monitor at address 0.7 (group 0, address 7) has acknowledged, that the local control is disabled: 0 1 2 3 4 5 6 7 8 0x06 0x07 0x50 0x4F 0x54 0x01 0xFE 0x00 0xFF Example 2 Send an invalid “POT” command to the monitor at address 0.7 (group 0, address 7).
Command Reference 6.5 MCC Unit Control Command This command is used for remote configuration of the video controller within the monitor. The video controller is an independent device, which controls the LCD panel. Because each monitor model can be equipped with different kind of LCD panel (size, resolution, type etc.), the used video controller can be also different from model to model. The MCC command is a container for video controller specific commands.
