Command format

All commands consist of 3 alpha characters followed by a request, all enclosed in “greater than” and “less than” signs. The request can be a read request (indicated by a “?”) or a write request (indicated by 1 to 4 ASCII digits).

A read request format: <AAA?> where

<starts the command

AAA denotes the command

? denotes the read request

> ends the command

A write request example: <AAA=####> where

<starts the command

AAA denotes the command

=#### denotes the value to be written (leading zeros not necessary)

>ends the command

Some commands have ranges, while others are absolute. If a number greater than the maximum range is received, it is automatically set to the maximum number for that function. With absolute settings, “0” is off, 1-9999 is on. The one exception is the Power command, where 0 is off and 1 is on.
