Setup Guide for the RadioRA Chronos System Bridge
66
Section 5 - RS-232 Programming
Overview
RS-232 Port Programming
This section contains information on how to setup the Chronos
TM
System Bridge for RS-232 integration with
other systems. The RadioRA
®
RS-232 Protocol and Programming Guide (P/N 044-038) contains information
regarding the RS-232 command set and how to interface the
Chronos
System Bridge with equipment external to
the
RadioRA
System. The
Chronos
System Bridge RS-232 port allows an external device to control
RadioRA
lighting loads and provides an external device with feedback of
RadioRA
activity.
Zone Numbers must be assigned to have an external device:
• Individually control a zone.
• React when a zone is changed locally.
Master Control Numbers must be assigned to have an external device:
• React when a Master Control button is pressed.
• Control the LED of a Master Control button which has no
RadioRA
loads assigned to it.
• React when a Raise/Lower button is pressed on a Master Control.
• React when a Cordless Master Control wakes up or goes to sleep.
Phantom Buttons must be assigned to have an external device:
• Activate Phantom Buttons 1-15, ALL ON (Phantom Button 16), or ALL OFF (Phantom Button 17).
• Monitor the status of Phantom LEDs 1-15.
For details on the commands required to perform the above functions, refer to the
RadioRA
RS-232 Protocol
and Programming Guide (P/N 044-038).
Depending on the application, Zone Numbers, Master Control Numbers, or Phantom Buttons may not have to be
assigned.
