Protocol Encoding; Examples - Planar LookThru LO552 Series User Manual


Note that enumerated and integer values can be written either in decimal or hexadecimal. For
example, a decimal value of '50' can be written in hexadecimal as '0x32'.

TERM is the termination character for the command. This can either be the ASCII carriage return
character (0x0D), the ASCII line feed character (0x0A) or a semicolon. The response will use the
same termination character.

5. Protocol Encoding


All parts of the command structure are case insensitive (e.g. "BRIGHTNESS", "brightness" and
BrIgHtNeSs" are all the same). Responses will always be in capital letters.

Excessive white space is allowed (e.g. "BRIGHTNESS=50", "BRIGHTNESS = 50" and
"BRIGHTNESS

Modifiers and operands can be separated by commas, spaces or both (e.g. "GAIN=100,100,100",
"GAIN=100 100 100" and "GAIN=100, 100, 100" are all the same). Responses will always
separate with one space between modifiers and operands).

6. Examples

[CR] is the ASCII carriage return character (0x0D).
Command
brightness = 100 [CR]
brightness = 100;
200=100 [CR]
brightness+ [CR]
brightness- [CR]
gain = 101 102 103 [CR]
gain(current red)+
gain(zone.1, all) = 104,105,106 GAIN(ZONE.1 ALL):104 105

Notes
Sets the Brightness value to 100
Also sets the Brightness value to 100,
but uses the ';' termination character
instead of [CR]. The response uses the
same termination character.
"200" is the numeric command code for
"BRIGHTNESS"
Increments the current Brightness value
Decrements the current Brightness
value
Example command with multiple
operators (sets Red Gain to 101, Green
Gain to 102 and Blue Gain to 103, on
the current zone)
Increments the Red Gain on the current
zone
Example command with multiple
modifiers, multiple operators and
different separators between the
modifiers and operators (sets Red Gain
to 104, Green Gain to 105 and Blue
Gain to 106, on Zone 1)
Example command with a string
operator
Example action command (no operator
or operand)
