Notes:
1. All initiated messages are prefixed with Axx, where “A” is an ASCII upper case
character (Hex code = 41). “xx” is a two-character hex code address in the range
00 to FF representing an ASCII code address range from 0 to 128. Hex address
00 is the general broadcast address to all devices.
2. All commands & responses end with an ASCII carriage return character
(Hex code = 0 D)
3. Any command can be aborted prior to sending a carriage return by sending a
Cancel (Hex = 18), or Escape (Hex = 1B) character. The PDU will discard any
previous characters, and immediately look for a valid address header.
4. PDU’s that receive messages with a correct address, but fail to recognize the
specific command parameters, or have illegal command parameters, will return a
response with the command that was entered followed by a “?”
5. Unit will respond to a broadcast command with address “00” only if the “Start”
button is depressed while the PDU is in the remote operation mode.
6. Lowest measured temperature is 0° C. There is no indication of minus temperature.
