2.4.3
RFBAND Switch
The RFBAND switch allows the user to select the Upper or Lower range of the available RF spectrum
for the RFDMX to operate in.
All TX and RX units in the same system must be set to the same RFBAND settings for correct operation.
In most installations, where a single RFDMX system is operating, the RFBAND will not need to be
changed.
In installations where there are two (2) RFDMX systems operating in close proximity to each other,
care must be taken to ensure the two systems are NOT using the same RFBAND setting.
2.4.4
NETID Switches
The NETID Switches allow the user to select up to 8 different spread spectrum channel hop sets.
All TX and RX units in the same system must be set to the same NETID settings for correct operation.
The NETID switches allow multiple RFDMX systems to co-exist over a wide area.
2.4.5
Transmitter (TX) to Receiver (RX) pairing
A single push-button is fitted to the RFDMX to initiate the pairing procedure.
The process for pairing RX units to a TX unit is as follows:
-
Ensure TX and RX units to be paired have the identical BAND and NETID settings on their DIP
switches.
-
Power up RX unit. Wait 5 seconds, then press SYNC button. The ACT LED will start to flash. RX
unit will remain in pairing mode, looking for a message from TX unit for 60 minutes.
-
Repeat for all other RX units that need to be paired synchronisation with the TX unit.
-
Power up TX unit. Wait 5 seconds then press SYNC button. ACT LED will flash for 5 seconds
and TX unit will send sync message to all RX units already set in pairing mode. After 5 seconds,
TX unit will return to normal operation mode.
-
All RX units within radio range and in pairing mode will receive sync message and bind
themselves to the TX unit. Once paired, the ACT LED will stop flashing and the RX unit will
return to normal operation, now linked to the TX unit.
The pairing process can be repeated as required to add new RX units to an existing system.
