AMX Lighting PROlink/AXlink Programming
PROlink commands should not be sent while the PROlink buffer is responding to the previous
command or a data collision could occur. In Axcess programs there should be at minimum a 3/10-
sec. wait (WAIT 3) between commands sent to the controller. Repetitive commands should have a
½ second wait (WAIT 5) between commands for greater accuracy. The dimmers all have the ability
to turn On or Off in 1/10 of a second.
A <CR> or '13' is sent before a command string will also clear the PROlink buffer allowing more
reliable data transfer.
A dimmer or group of dimmers can be excluded from a preset using the 'Undefined' command.
Undefined is a level command that allows a dimmer to be ignored during the recording of a preset;
it has no defined level. A preset can be created where dimmers 1 and 2 can be set to 50% while
dimmers 3 and 4 are set to undefined levels.
The following example shows a command line where any undefined dimmers wouldn't be included
in a preset:
If all lights were on full before this preset was recalled, then only dimmers 1 and 2 would go to 50%
while dimmers 3 and 4 would stay at full. This is useful where one AMX Lighting enclosure must
service several rooms or when a preset is needed for only one light in the entire room. The 'All
Levels Undefined' command is often used before recording a preset to clear the scene to a 'neutral'
level. A preset stored with all levels undefined will have no affect on the dimmers when recalled.
The following example shows a command line where any undefined dimmers wouldn't be included
in a preset.
Use this type of preset to initiate unique actions that do not change the lighting. All unique action
presets can be assigned to AXlink, PROlink, or dry closure panels. This allows any AMX Lighting
panel to do non-lighting functions. A non-lighting preset could be used to turn on music or set an
alarm. A preset using all levels undefined will still be counted as one of the available 128 presets
and there can be many presets that do nothing to the lights.
PROlink Command Structure
Sample format:
Send_String <device>, "'<n>L<m>T<t>', 13"
Variables: • <n>: This is the dimmer number from 1-60 (Any combination of dimmers
• <m>: This is the dimmer level percentage 0-100
• <t>: This is the time value, 0-255 in seconds
Example:
Send_String LTS, "'1L57T3', 13"
PROlink response example:
C
001 LEVEL 57 IN 003
• Example:
Send_String LTS, "'3-4LU'"
• PROlink response example:
C
GROUP LEVEL UN IN 000
AXlink cannot 'Undefine' a single channel.
• Example:
Send_String LTS, "'ALU', 13"
• PROlink response example:
C
ALL LEVEL UN IN 000
