Installation Instructions
Model NIM-1M
Network Interface Modem Module
OPERATION
The Model NIM-1M plug-in modem board from
Siemens Industry, Inc., mounts to and is connected to
the NIM-1W board to provide modem communication
capability for an MXL System XNET network.
The modem transmission line connected to the
NIM-1M can only be Style 4 and can be made using
standard 18 AWG shielded twisted pair or data
grade phone lines.
Note: A pair of NIM-1W / NIM-1M board sets is
referred to as a “bridge” in this document.
INSTALLATION
Remove all system power before installation,
first battery and then AC. To power up, connect AC
first, then the battery.
Setting the Switches
Before mounting the NIM-1M modem module on the
NIM-1W, set all the switches and configuration
jumpers on both modules. Refer to the NIM-1W
Installation Instructions, P/N 315-099165 for infor-
mation on setting the switches on the NIM-1W.
NIM-1M SETTINGS
The NIM-1M has three configuration headers (refer
to Figure 1). The NIM-1Ms are always connected in
board sets, or pairs, with NIM-1Ws to form the
bridge. Designate one board set as NIM-1M LOCAL
and the other as NIM-1M REMOTE. Program the
NIM-1Ms as shown in Table 1.

Mounting
The NIM-1M is mounted on the NIM-1W with 4 nylon
spacers.
1. Snap the 4 nylon spacers into place in the holes
on the underside of the NIM-1M board in the
positions indicated in Figure 2.
2. Position the 4 spacers on the NIM-1M over the 4
holes on the component side of the NIM-1W.
Refer to Figure 3 for representative location of
the NIM-1M on the NIM-1W. Press the spacers
firmly into place in the NIM-1W one at a time.
Cable Connections from NIM-1M to NIM-1W
The NIM-1M has a cable attached to the underside
of the board that connects to JP1 of the NIM-1W.
The cable plug is polarized and connects one way
only. Refer to Figure 3 for the location of JP1. Refer to
the NIM-1W installation instructions, P/N 315-
099106, for installing MXL WAN.

NOTES:
1. "ON" IS WHEN THE JUMPER IS IN THE PROPER POSITION
OVER PLUGS JP1, JP2, OR JP3.
2. THE CABLE THAT CONNECTS THE NIM-1M TO THE NIM-1W
IS ATTACHED TO THE UNDERSIDE OF THE NIM-1M.

ELECTRICAL CONNECTIONS
Note: All connections to the NIM-1W / NIM-1M board
set are power limited to NFPA 70 per NEC
760. All connections are also supervised.
NIM-1M Modem Connections
Modem connection to the NIM-1M can be made
through the standard RJ11 jack (P2) or through TB1
(refer to Figure 2). If TB1 is used, connect TB1-1 TIP
Local to TB1-1 TIP Remote and TB1-2 RING Local
to TB1-2 RING Remote. P1 is for factory use only.
TB1 terminal assignments are as follows:
TB1-1 TIP
TB1-2 RING
TB1-3 LOCAL EARTH GROUND
TB1-3 must be connected to local earth ground. If
shielded cable is used, connect shield to local earth
ground at one side of modem connection only.
Note: When an MXL XNET network using the model
NIM-1W with model NIM-1M board set is

Mounting the NIM-1M Module Board on the NIM-1M Module Board
brought on line, there may be some delay in
network communications while the modems
on the model NIM-1M board establish com-
munications. This may cause a temporary
system trouble which can be cleared once
communications are established.
Refer to the NIM-1W Installation Instructions, P/N
315-099165, to continue with the installation of the
NIM-1W / NIM-1M board set.
