7.3.1 kGetModInfo (frame ID 1
d
)
This frame queries the module's type and firmware revision number. The frame has no
payload. The complete packet for the kGetModInfo command would be:
0005 01 EFD4
Where “0005” is the byte count, “01” is the kGetModInfo command, and “EFD4” is the
CRC-16 checksum
7.3.2 kModInfoResp (frame ID 2
d
)
This frame is the response to kGetModInfo frame. The payload contains the module type
identifier followed by the firmware revision number.
Type Revision
UInt32 UInt32
Payload
2
Frame ID
kUlnt8
Note that the Type and Revision can be decoded from the binary format to character
format using the ASCII standard. For example, the hex string “00 0D 02 54 43 4D 35 31
32 30 38 C7 87” can be decoded to read “TCM5 1208”. Also, the TCM XB is referenced
as Type “TCM6” since the number of Type characters is limited to 4.
