Operations Commands Operations commands allow more flexible and direct control of the projector. The syntax
for operations commands is as follows:
op <operation> <command>[CR]
(Precede <operation> and <command> with a space.)
The command type can be one of 5 functions:
Table 6-2 lists the valid operations commands. For all but Execute functions, the response
from the projector is the command and “= <value>” where <value> is the current value or
“NA” if the value is not available. For Execute functions the response is the same
command. All responses are in UPPERCASE.
Some operations command examples:
Input: op bright ? [CR]
Response: OP BRIGHT = 100 [CR]
Input: op bright + [CR]
Response: OP BRIGHT = 101 [CR]
Input: op bright = 127 [CR]
Response: OP BRIGHT = 127 [CR]
Input: op bright - [CR]
Response: OP BRIGHT = 126 [CR]
Input: op resync [CR]
Response: OP RESYNC [CR]
