Introduction
The P25 Digital Vehicular Repeater ( DVR-LX ) is used to extend portable radio
communications. When the DVR-LX is interfaced to a Motorola Mobile Subscriber Unit
(
MSU ), the complete equipment package is referred to as Digital Vehicular Repeater
System ( DVRS ).
When a Portable Subscriber Unit ( PSU ) has difficulty reaching a system tower, a DVR-
LX can help by linking the PSU to a higher power mobile radio or MSU. The DVR-LX is
designed to be seamlessly interfaced to:
•
Remote Mount APX Series MSU with or without a Control Head (O2, O3, O5,
O7, O9, or E5)
•
For full list of compatible MSUs refer to compatibility chart at Futurecom.com >
Support > Documentation and Software > DVR-LX/DVR/VRX1000
NOTES:
•
MSU must be configured as Remote Mount to be compatible with the DVR-LX.
•
APX8500 MSU may require interface kit. Please refer to the DVR/VRX1000
Ordering Guide.
•
The MSU configured for DVRS operation can support up to two control heads.
•
All control and status of the DVR are provided by the APX MSU control head.
The control head is mounted in the front of the vehicle while the DVR-LX and
associated filtering is housed in the back.
