This test shows that you have a terminator in place, and also that you have continuity of Data- and
Data+ between installed devices. If the measured resistance is significantly less than 100 ohms,
(say 40-80 ohms) it suggests you may have multiple terminations in place. Check that any
terminator switches on light fixtures are OFF. If impedance is very low, check for wiring shorts.
RDM Connections
RDM refers to ANSI E1.20, a control protocol in the entertainment industry gaining popularity and
essentially an “extension” of DMX512. The use of RDM is optional – but it does require a DMX512
cable connection.
Important – RDM and RDM Integration
RDM (Remote Device Management) is an ANSI standard that adds bidirectional discovery and
status monitoring to a standard DMX network connection. No additional wiring is required for
RDM operation.
DEC3’s RDM implementation allows system integrators to set up remote control and status
monitoring of all attributes and sensors, including:
•
Temperature
•
Humidity
•
Lamp Current
•
Elapsed Lamp Hours
•
Lamp Relay Status
•
Fan Relay Status
•
Heater Relay Status
•
DMX Status
•
DMX Start Address
•
DMX Personality (RDM Mode)
•
Device Type
•
Device Label
•
Software Version
Tempest Lighting warrants that its RDM products are compliant to the RDM standard, but does not
directly support RDM system integration. Tempest Lighting will however provide introductions to
qualified RDM system integrators for customers requiring assistance in this area. Links are
provided on the Tempest Lighting web site (www.tempestlighting.com).
