<45> Two byte ASCII Command 45 echoed back from the receiving unit (2 bytes).
Device type is an ASCII string transmitted by the receiving unit that defines the
unit family product code. For Millennium devices, the return ASCII string is “M-
485”. For Edward’s Visual devices, the return ASCII string is “S-485”.
Receiving Unit’s Firmware version and revision level.
The character has a value of 3 hexadecimal and is required at the end of
every message (1 byte).
Receiving unit calculates two-byte checksum and returns ASCII value. Refer to
Section 4.0 for Block checksum calculation and verification.
Example: Command: 014500A00
Response: 01M-485v1.084
