Installation
Setting Jumper E6
If the backup amplifier is an EL-410C/D,
place jumper E6 in the right-hand
position. This connects the backup
amplifier input negative side to the
MXLV power supply.
Place the user key from the installation
kit in the OMM-1 card edge connector
for the ASC-1 (between positions 25-
26 and 27-28).

If one backup amplifier is shared by
more than one ASC-1, connect terminal
3 of the terminal block of the primary
ASC-1 to terminal 3 of the terminal
blocks of all of the other ASC-1 cards
that share the same backup amplifier.
If the system has NO backup ampli-
fier, place a jumper across terminals 3
and 4.
After the addresses and jumpers are
set, install the ASC-1 in the OMM,
being sure that the module is riding in
the card guides and is firmly seated in
the card edge connector.
Installing the ASC-2
The ASC-2 plugs into a half-width slot
on the OMM and comes with an
installation kit that consists of the
following:
One end of line resistor,
P/N 140-820405
One user key
Setting the Addresses on the ASC-2
Before installing the ASC-2 in the OMM,
set S1 and S2. Use S1, DIP switches
SW1-SW4 to set the network address.
Refer to the CSG-M configuration
printout for the address of the module.
Use the ASC-2 S1 Settings table to set
the address for this switch.
Set switch S2 for proper amplifier
supervision of the ASC-2. Check the
system wiring diagram for amplifier
and riser assignments. Set switch S2
DIP switches SW1 and SW2 using the
ASC-2 S2 Settings table. SW3 and SW4
on S2 are not used.
