INSTALLATION

Before the RFL VF-15C can be placed in service, it must be installed in a multiplexer shelf.

Installation involves determining the module slot in the Main Shelf or Expansion Shelf where the

module will be installed, inserting a Module Adapter into the rear of the shelf behind the module slot,

connecting all signal and power wiring to the Module Adapter, checking the settings of all switches,

and inserting the module into the front of the shelf.

NOTES

Power supply and time slot considerations may affect the installation of this module into an

existing multiplexer shelf. Refer to the multiplexer manual for more information.

The following instructions are provided for installing an RFL VF-15C module into an existing system.

If the module was included as part of a system, installation was done at the factory. Otherwise, proceed

as follows:

1. Carefully inspect the module for any visible signs of shipping damage. If you suspect damage

to the module, immediately call RFL Customer Service at the number listed at the bottom of

this page.

2. Determine the module slot in the Main Shelf or Expansion Shelf where the module will be

installed.

RFL VF-15C module occupies one module slot in the Main Shelf or Expansion

Shelf.

3. Determine which Module Adapter will be used to make connections to the RFL VF-15C

module.

Each module in the IMUX 2000 multiplexer requires a Module Adapter. The

module adapter provides the appropriate connector for the desired interface.

There are four Module Adapters compatible with the RFL VF-15C:
