Connecting a Terminal or Computer

To connect the 58502A to a terminal or computer, you must have the proper interface cable. Most computers are DTE (Data Terminal Equipment) devices. Since the 58502A is a DTE device, you must use a DTE-to-DTE interface cable when connecting to a computer. These cables are also called “null-modem” cables. The rear-panel RS232 port is DTE.

The interface cable must also have the proper connector on each end and the internal wiring must be correct. Connectors typically have

9pins (DE-9 connector) or 25pins (DB-25 connector) with a “male” or “female” pin configuration. A male (m) connector has pins inside the connector shell and a female (f) connector has holes inside the connector shell.

To simplify interface cable selections, the following subsections tell you which cables to use.

To Connect a Terminal or Computer to the 58502A

Use an HP 24542U interface cable (or equivalent RS-232 null-modem cable with DE-9S female connectors at each end) to connect the 58502A’s rear-panel RS232 port to a terminal or computer as shown in Figure 3-3.
