the full frequency band when DVR-LX is not enabled or to block certain frequencies
when DVR-LX is active to ensure interference-free communication.
When the DVR-LX is paired with a non-APX8500 MSU, the switch bypasses the filtering
at the output of the MSU when a DVR-LX disabled talk group (TG) is selected on the
MSU control head.
To enable the RF bypass switch operation, the following must be configured via
Futurecom Repeater Configurator (FRC) in the Hardware Setup menu (Figure 2):
•
MSU RF Bypass Switch = checked (enabled)
•
Relay Use- Relay 1 = MSU RF Bypass Sw.
RF Bypass Switch with APX8500 MSU with Triplexer and Single Band Antennas
If installing an in-band DVR-LX, it comes equipped with an internal RF bypass switch.
This switch bypasses the filtering at the output of the MSU as required to allow access to
the full frequency band when DVR-LX is not enabled or to block certain frequencies when
DVR-LX is active to ensure interference-free communication.
When the DVR-LX is paired with an APX8500 MSU using a triplexer and single band
antennas, the switch bypasses the filtering at the output of the MSU when a DVR-LX
disabled talk group (TG) is selected on the MSU control head.
To enable the RF bypass switch operation, the following must be configured via FRC in
the Hardware Setup menu (Figure 2):
•
MSU RF Bypass Switch = checked (enabled)
•
Relay Use- Relay 1 = MSU RF Bypass Sw.
