Error Code: Only For i-7540D’s COM3 (CAN port)

If the Error response function on the i-7540D module is set to be “Yes”(that mean enable) via the i-7540D Utility during the configuration period, the i-7540D will send the error code to the device of the host PC through the Ethernet port 10003 when the i-7540D produces an error message automatically during the operation mode. The meanings of these error codes are given below:

1

Invalid header

The RS-232 command string header is not “t”,”T”,”e”,”E”.

 

 

 

 

 

The length of command string is invalid. For example:

2

Invalid length

—

Error: t0013112233

 

 

 

Right: t0013112233<CR>

 

Invalid CAN

The CAN identifier bits depend on CAN specification

3

CAN 2.0A: total 11 bits, 0x000 ~ 0x7FF

 

identifier

CAN 2.0B: total 29 bits, 0x00000000 ~ 0x1FFFFFFF

 

 

 

 

The data byte of the CAN Message does not match the data

4

Invalid CAN

length of the CAN Message. For example:

data length

—

Error: t001512345<CR>

 

 

 

—

Right: t00150102030405<CR>

 

 

 

 

If the i-7540D CAN baud rate is not the same as the CAN baud rate on the CAN network, the ER LED on the i-7540D will be flash with a constant frequency and the TX LED will solid green because the i-7540D cannot send any CAN messages to the CAN network. Therefore, users will need to read the i-7540D status by using the command “99S” (in the section 4.5) to help users understand what is going in the module. In general, the following errors could occur: CAN media connection problem, terminal resistor problem, different baud rate configuration with CAN network and so on.
