The following is a description of the Data Inquiry-M–Traverse Response Characters.

Character 1 - STX:

This is the first character in the character string.

Characters 2, 3 Device Number:

This is the two character access address for the M–Traverse.

Character 4 -Error Code:

If there are errors in the transmission that the M–Traverse receives from the host

computer, the Error Code will display them. Use Table 3-42 to convert the ASCII

code to binary. Then the binary code can be decoded as follows:

Bit 7 Always “0”.

Bit 6 Always “1”.

Bit 5 Always “0”.

Bit 4 1 = Control Mask Error / Lockout during Run state.

Bit 3 1 = Minimum / Maximum Error (out of range).

Bit 2 1 = Data Error (invalid data).

Bit 1 1 = Parameter Error (invalid parameter or message type).

Bit 0 1 = Transmit Error (parity, framing, overrun, no STX or no ETX).

Note: The M–Traverse will only accept data if there are no errors. The ASCII error

code “@” (Binary code “1000000”) indicates that the Host Transmission

contains no errors. Also see MV-74 for the ASCII Error Code for the last

Response Message.
