Programming Strings

AMX Lighting PROlink/AXlink Programming

To determine if a AMX Lighting level is in the 'UNDEFINED' state you must use the PROlink

string command for single dimmer status as described in PROlink - Status section under the

heading 'Dimmer status'. The AXlink layer could report a level as FF (all on), but at the same time

the PROlink layer has assigned that channel as 'UNDEFINED'; this will make a difference when

recording presets. Presets are stored using the PROlink layer, not the AXlink layer.

Levels are returned in AXlink as an 8-bit figure with 256 steps from 0 to 255. Use the formula

x = (x*100/255) [where x is the dimmer level] to express an 8-bit level in percent. This will give an

approximate percentage level, with a 1% accuracy.

Buffers

The recommended way to determine a AMX Lighting response to a buffer is to use this format:

LTS_RESPONSE = REMOVE_STRING (LTS_BUFFER,"13,10", 1) '

There are a few constants that may help in PROlink string manipulation. Presets use the 'GOTO'

command, levels are preceded by the word 'LEVEL', and time values are preceded by the word 'IN'.

Responses

The responses from the AMX Lighting controller can be turned Off in order to quickly send

commands. Commands can be sent faster if there is no waiting for a response after each command

is sent. The default mode at startup is RXON, which will allow responses to be sent from the AMX

Lighting controller. It is recommended to send a command and wait for the response, then send

another command. Use the RXOFF mode to avoid data collisions. This will disable most of the

return responses from PROlink and speed up the data transfer rate. It will also stop all feedback.

Dry Closures

Dry closures are read in sequential order and are assigned to AXlink channels 147 - 154. If two

buttons are pressed simultaneously, only one channel will be active. Buttons on closures must be

pushed sequentially to have more than one channel active. Pushing dry closure #1, then #2, then #3

will activate all three channels (AXlink channels 147, 148, 149). All eight closures can be used at

once.

Refer to the Create_Buffer subsection on more information on creating a buffer.
