Q:

DSU 5600 Interface Pinouts

A:

The following charts give the pin assignments for the DSU 5600 connectors. They can also be found in the DSU 5600 User Manual, Chapter 2. Installation.

Network Connections

This interface consists of four leads paired to provide separate transmit and receive circuits. The four leads are provided on the eight position modular jack (RJ-48S) labeled TELCO on the rear panel of the DSU 5600.

Pin Assignments for Primary EIA-232 Connector

The data terminal equipment is attached to the connector labeled PRIMARY EIA-232 at the rear of the DSU 5600. The maximum cable length recommended is 50 feet.

The EIA-232 connector works up to 56 kbps with a low capacitance cable or with the external transmit clock option selected. The primary DTE rate is configured from the front panel. The primary DTE can operate in asynchronous or synchronous modes.

To prevent possible radio frequency interference emissions, a shielded cable is required.
