External application/device profile plug in
The External Application/Device profile is a specialized profile that enables communication from LJ to
a 'plug in' type application rather than a DMX device. The plug in application may in turn control other
applications or external devices. The profile acts like a regular fixture profile - this means that the
external application or device can be controlled and programmed in the same contexts as a regular
DMX fixture (e.g. programmed in scenes/sequences/cues, statics etc).
An example of an eternal plug in application is LJ-RS232Send that allows control of RS-232 devices
from LightJockey - LJ-RS232Send can be found in <Main LJ Folder>\LJ-RS232Send\, please see LJ-
RS232Send help file for more documentation.
Capabilities
The capabilities of the External application/device link depends entirely on the external application
itself - the following section lists the possible options, which may or may not be implemented in the
external application.
String based interface
The external application link implements a string based interface where commands strings are sent
from LightJockey to the external application. Command strings may contain ASCII characters from
CHR(32) to CHR(127) with a length not exceeding 32 characters pr command (scene). If the external
application is controlling an external device, it is up to the external application to transfer the
command strings into something meaningful for the device.
DMX out & in channels
Besides the commands string, the external application link may transfer the value of up to 4 user
configurable DMX output channels and 4 user configurable DMX input channels pr profile. Note, there
is a maximum limit of a total of 8 DMX output channels unless the selected output channels are within
the addressing space of configured DMX transmitter hardware.
