vides front and rear views of the LDM-16. The nest requires access to 120Vac

power. It is equipped with a 2Amp fuse located along the rear panel.

TTACHING THE NETWORK LINES

The LDM-1 is designed to operate with four-wire private line networks. Both

the transmit and receive channels are polarity sensitive. The network’s + con-

ductor must always be wired to a corresponding + input at the rear panel.

Network lines are secured to appropriate screw-down terminals at the quick-

disconnect plug. The rear panel silk screening clearly labels each connector

position. The cable that connects the LDM-1 to the network should be lim-

ited to 100ft. in length.

ONNECTING TO THE DTE

The LDM-1 can be used with any DTE that utilizes an RS-232 interface. The

LDM-1’s operation is asynchronous. It uses the Baud rate selected by the

DTE. The DTE connects to the DB-25 female connector located at the

modem's rear panel. The pin assignments for the modem’s DB-25 connector

are listed in Figure 7 on page 31. It is wired in accordance with DCE stan-

dards.

This completes the chapter on how to set up and install the various LDM

products. The next chapter describes how to operate the modem and how to

use its self-test features.
