4 Quick Start Guide
4.1 Hardware Wiring
1. According to the RJ-45 port instructions in chapter 3, properly wires every pin of 5-pin terminal.
2. According to the CAN interface instructions in chapter 3, properly wires at least pin 2 and 4. Noted it is
not the right time to power on.
3. Check the wiring is correct in manual instructions.
4. Power on the module, enter into the run mode.
4.2 Software Installation
Double click the installation package and install the configuration software SST-EC-CFG.
4.3 Communication Debugging
1.Please connect the Ethernet port to PC when GT200-MT-CA is first used, and turn the DIP switch to
2ON1OFF(configuration mode), then power on the module. The IP address should be 192.168.0.10. The segment
of the PC should match with 192.168.0.X. Use Crossover cable when the gateway connects with PC directly,
when they are connected by switch or router, then use straight-through cable.
2. Open SST-EC-CFG, search current network equipment for statically configured devices.
3. According to the method of software configuration, configure the related parameters of CAN and Modbus
TCP according to the actual application requirements.
4. Switch the DIP switch to 2OFF1OFF(run mode) and reboot the system and the configurations will become
effective.
5. Install GT200-MT-CA to standard DIN rail, power on and use it.

5.1 Precautions
1. Please set the DIP switch (bit 2) to ON as the product is used for the first time, and configure the
parameters in the static configuration. Noted the IP conflict will cause the start-up failure of the product.
2. Users can upload/download configuration in the static configuration, the product cannot communicate

6 Working Principle
6.1 Modbus TCP/CAN
6.1.1 Data Exchange
The receiving and sending of CAN frame is FIFO.
6.1.2 The Relationship between Them
The following is how to encapsulate a CAN frame with 16-byte (8 registers)
a) Modbus TCP input register
Use function code 04 to read the Modbus input register, that is CAN receive data.
The starting address is 0.
Every frame has to read 8 registers (16 bytes), or it will return Modbus exception response.

If GT200-MT-CA received CAN frame on CAN network, the sequence number of input frame will add 1.
Users decide whether to use these CAN frame according to the needs.
b) Modbus TCP output register
Use function code 16 to write the data to Modbus output register of GT200-MT-CA, that is the CAN frame
needs to send.
The starting address is 0.
Every frame must include 8 register (16 bytes), or it will return Modbus exception response.

c) Bytes Definition
Byte 0 to 3 are controlling bytes
Byte 0: it indicates sending this sequence number of CAN frame once if it is zero, and it indicates sending
this sequence number of CAN frame periodically if it is non-zero, the cycle value is decided by this byte value:
period of transmission=the value of byte 0 * 10ms. For example, if the value of byte 0 is 10, the period of
transmission is 100ms, that is to say sending the frame one time every 100ms.
Byte 1: indicates the data number of CAN frame, the range is 0~8.
Byte 2: sequence number. The initial value of sequence number in output frame is non-zero (any value except
zero), if the mode is single transmission mode, the number must add 1 when sending a new frame, the gateway
will recognize that it is single transmission data, if the number reaches 255, the number will be 0 when adding 1.
CAN frame sequence number sends now must be different with the entire CAN frame sequence number sent last
time, or it won’t do any operation to current CAN frame.
Byte 4 to 7 are CAN frame header and CAN frame mode control (29 bit CAN ID). If the current CAN ID of
CAN frame is same with one in a cycle of transmission, the latter is removed, the current CAN is frame kept into
the buffer.

Time stamp: the time that GT200-MT-CA received CAN frame from the CAN port.
(Explanation: Only if the time stamp function is enabled in SST-EC-CFG will GT200-MT-CA adds the
receiving time of CAN frame to CAN frame header automatically. At this point, the CAN frame that GT200-MTCA forwarding to Ethernet is 17 bytes long frame with time stamp. Additionally, GT200-MT-CA applies 13 bytes
long CAN frame without times tamp)
Control byte: occupies one byte including the extended frame signs, remote frame flag and the frame data length;
EXT: Extended frame flag, 0 indicates the standard frame, 1 indicates the extension frame;
RTRTAG: Remote frame flag, 0 indicates that the data frame, 1 indicates the Remote frame;
Frame data length: the range is 0~8.

8 Operation Maintenance and Cautions

Prevent great pressure or it will damage the panel.

Prevent collision or it may damage the inside elements.

Supply voltage is DC 9V-30V; it must be controlled within the range of manual demand to prevent the
module burned.

Prevent water or it will affect the normal work.

Please check on the wiring before powering on. Make sure there is no wrong wiring or short circuit.
