Command Format
All commands consist of 3 alpha characters followed by a request, all enclosed in parentheses. The
request can be read request (indicated by a "?") or a write request (indicated by 1 to 4 ASCII digits).
Error Conditions
Not all commands consist of 3 alpha characters followed by a request, all enclosed in parentheses. The
request can be a read request (indicated by a "?") or a write request (indicated by 1 to 4 ASCII digits).
Read Requests
A read command returns a text string or the range and the current setting, for example:
Function
Volume
Source
Lamp Hours
Max Lamp Life
Command
(VOL?)
(SRC?)
(LMP?)
(LIF?)
Returns
(0‐20, 12)
(0‐3, 2)
(0‐9999, 42)
("5000")
Write Requests
Some commands have ranges, while others are absolute. If a number greater or less than the maximum
range is received, it will return an error "?".

Source
Ceiling Set

Write/Read Requests
Most commands have a "& Return" option you can use by adding a "!" before the final parenthesis. This
will add a read command after the write command has been processed. For example, (PWR1!) would be
equivalent to entering (PWR1)(PWR?).
