Installation Instructions
August 12, 2005
1. Follow all shutdown procedures necessary to
prevent damage to any equipment or harm to any
personnel.
2. Turn OFF power to the MEC/MBC/RBC enclosure.
3. In the MXL enclosure, locate the NIM-1R or
NIM-1W module (hereafter referred to as the
NIM-1 module). This module will be plugged into
the connectors on a MOM-2 or MOM-4 module. If
it is plugged into a MOM-4 module, note whether
the NIM-1 module is plugged into the slot closest
to the terminal block labeled TB3 or TB4.
4. If the NIM-1 is plugged into a MOM-2 module,
or if it is plugged into the slot closest to terminal
block TB4, the following instructions apply to
connections on TB4. If the NIM-1 module is
plugged into a MOM-4 module, in the slot closest
to TB3, the instructions apply to connections on
TB3.
5. Connect one end of the shielded twisted pair
cable to terminal 1 and 2 on the appropriate
terminal block, as specified above. Terminal 1
is the negative (-) terminal, and terminal 2 is
the positive (+) terminal. There is no terminal
available for the shield, so it will be connected at
the driver. (See Figure 1 and Figure 2.)
6. Connect a 120-ohm, 1/4 watt resistor between
terminals 3 and 4 of this same terminal block.
See Figure 2.
7. At the MEC/MBC/RBC, attach the +, -, and S
leads of the RS-485 cable to an FLN/PMD trunk
connector. Allow an additional 12 inches (305
mm) of cable before terminating to the connector.
The standard practice used by MXL
installers would also require a 120-ohm
resistor between terminals 1 and 2.
Do NOT install a resistor across these
terminals.
8. Turn ON power to the MEC/MBC/RBC enclosure.
9. Start any other equipment that might have been
shut down for this installation.
