LED Commands
The LEDs can be controlled individually or using a block formatted
command.
In order to ensure that LEDs are updated after a power failure or after an
interruption of the communications link, the LEDs should be refreshed
frequently by the CX9200. Therefore, Andover Controls recommends
using the block formatted command and updating all of the LEDs on a
regular basis.
The Block LED Command
The block LED command consists of a left parenthesis, followed by up
to 240 status characters, and ending with a right parenthesis. The first
status character controls LED 0, the second controls LED 1, and so on.
The status characters are as follows:
X Turns the LED ON
Z Turns the LED OFF
F Causes the LED to FLASH
For example, the following command would cause LED 0 and LED 3 to
turn ON, LED 1 and LED 2 to turn OFF, and LED 4 to FLASH:
(XZZXF)
Individual LED Commands
The LEDs can also be controlled individually. The led command
consists of a left parenthesis, followed by the LED number, followed by
the status character, and ending with the right parenthesis.
The LED number can be from one to three digits and any leading zeroes
will be ignored. The status characters are the same ones that are used
with the block LED command: X -> ON, Z -> OFF, F -> FLASH.
For example:
(1X)
Turns
ON
LED 1
(7Z)
Turns
OFF
LED 7
(3F)
FLASHES
LED 3
(03F)
