F.4 TP64 Installation
Normally, the TP64 is shipped with the Main and Standby transmitters per the customer order.
The receiver end of the link does not require a TP64 for a redundant standby configuration.
Main/Standby Retrofit
If the TP64 is to be installed in an existing site to convert a standalone unit to a main/standby,
particular attention must be made to set up all of the parameters as discussed in this manual.
STARLINK STL transmitters in a redundant standby retrofit are relatively simple to setup in the
field. The system installer may want to call Moseley Technical Services for assistance.
F.4.1 TP64 Rack Installation
The TP64 Transfer Panel is normally mounted between the Main and Standby radios to allow
the shortest possible lengths of transmission cable.
The TP64 is designed for mounting in standard rack cabinets. The chassis has mounting holes
for Chassis Trak C-300-5-1-14 rack slides. If rack slides are used, be sure to leave at least a
15-inch service loop in all cables to the equipment.
If rack slides are not used, use the rack mounting brackets (“rack ears”) and hardware included
with the TP64.
F.4.2 TP64 Power Supply
The TP64 main power (+12/+15 VDC) is supplied by the shielded RJ45 cable from both radios
and therefore requires no external power connection. The Main and Standby radio supplies are
summed internally in the TP64 so that if power from one radio fails, power to the TP64 will not
be interrupted.
Turn on the internal supply of the TP64 by switching the rear panel power switch up. This
supplies the internal electronics of the TP64. This switch should be left ON all the time.
Optionally, a wall-mount AC-DC power converter may be used for added back-up. The
converter may also be useful for testing and troubleshooting. If you require an AC power
converter, contact Moseley. Specify 115 Volt or 230 Volt when ordering. DC-DC converters
may also be used, contact Moseley for availability.
