DataTalker Owner’s Manual

5.1 Introduction

This chapter describes how to connect the DataTalker to your system (Table 5-1) and how to move the RS232/V.35 shunt when a V.35 interface is used (Table 5-2). Then it describes how to power on your DataTalker, check that the unit is cabled and configured correctly, and what to do if you run into problems.

5.2 Cabling

Connecting the DataTalker to your system requires two to four cables, depending on how you intend to use the DataTalker. Each cable connection will be explained in detail in the following procedures. When you cable the unit, you should consider how you configured it in Chapter 4. For instance, if you configured the unit for a sync data channel, you cannot connect a standard RS232C cable to the DATA/COMMAND connector on the back of the DataTalker. The following cabling procedures relate the cables to the configuration.

2If you are using your DataTalker with an internal composite link device, connect one of the two phone cables supplied with your unit to the appropriate internal composite connector:

MMH2834 Modem, Dial-up

Connect the RJ-11 phone cable supplied with the DataTalker from the internal modem DIAL- UP jack on the back panel to the dial-up line jack.
