Niles Audio MRZ-6 - Manual (Page 12)

Distributing IR Commands Between Units
Using the IR DATA IN and IR DATA OUT
The IR DATA IN and IR DATA OUT jacks are used to cascade IR data (TTL level, active high) from one unit to the next.
• In a multiple MRZ-6 system, the Master MRZ-6 always receives the data coming in from the Slave MRZ-6
units. See Figure 15
• The ZONE DIP switches route IR data received at the MRZ-6’s IR DATA IN jack to the Dedicated flasher.
All data is passed to the Common flashers regardless of the DIP switch settings. See Figure 15, page 19 of
the MRZ-6 manual.
