INSTALLATION
Before the RFL DS-961DE module 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 DS-961DE 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.
The RFL DS-961DE module occupies one module slot in the Main Shelf or
Expansion Shelf.
3. Each module in the IMUX 2000 multiplexer requires a Module Adapter. The module adapter
provides the appropriate connector for the desired interface.
The DS-961DE Data Module uses an MA-404A Module Adapter. The MA-404A
accepts up to five RS-232C lines via RJ-11 modular input connectors. Figure 1
shows the input jack arrangement. If you are setting up the module for two
channels at 19.2 kbps each, use only the first two jacks. For three channel
operation, use the first two jacks for 19.2 kbps and the fifth jack for 9.6 kbps. The
modes of operation are illustrated in Figure 2.
Jumpers on the MA-404A are used to select normal or three channel mode of
operation. For NORMAL mode (two or five channel), set jumpers J1, J2 and J3 to
the NORMAL position. For THREE CHANNEL mode, set jumpers J1, J2 and J3
to the THREE-CHANNEL position. Figure 3 illustrates these jumper settings.
4. Insert the MA-404A Module Adapter into the rear of the slot which will hold the RFL DS-
961DE module, and make all connections to the module adapter.
Connect the RJ-11 input lines, and insert the MA-404A into the rear of the slot
that will hold the DS-961DE module.
