Infrared communications
The infrared connection provides a non-intrusive wireless connection with the instrument
and maintains NEMA4X AND IP66 integrity.
No need to get access to the back of the controller to communicate with the instrument,
no need to take your screw driver to wire the communication cable, no wiring mistake
possible. You can now duplicate an instrument’s configuration, upload or download a
new configuration in a matter of seconds, just by pointing your Pocket PC in the direction
of the instrument.
It takes just a few seconds to upload a configuration from an instrument. You can then
save the configuration file onto your PC or pocket PC for review, modification or
archiving. Furthermore, this software also gives you important maintenance information
on the controller: instantly, get information on the current operating parameters, digital
inputs and alarm status, identify internal or analog input problems.
Question: What if I have several controllers on the same panel? How can I be sure I am
communicating with the correct one?
Answer: The infrared port of the controller is normally “off”. You activate the infrared
port by pressing any controller’s key. You can now communicate. After 4 minutes, the
port will be shut down again. Each controller may also be assigned a different
communications address.
