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:

TB1-2 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.

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.
