Runco LS-3, LS-5 operation manual 2.Serial Commands

Serial Communications

Decrement	-	Subtracts 1 from the current value.
Execute	(none)	Performs an action such as a reset.

Table 6-2lists 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]
Input: op sharp.mode = 1 [CR]
Response: OP SHARP.MODE =	1 [CR]
Input: op sharp.simple = 50 [CR]
Response: OP SHARP.SIMPLE	= NA [CR]
Input: op sharp.simple ? [CR]
Response: OP SHARP.SIMPLE	= NA [CR]

The last three commands show what happens when a control is grayed out. In this case, the sharpness mode was set to advanced (value = 1) and then the simple sharpness slider was attempted to be adjusted and queried. The response was “NA” or not available.
