RS-232 Interface Configuration

Connection to a Computer or Terminal

To connect the power supply to a computer or terminal, you must have the proper interface cable. Most computers and terminals are DTE (Data Terminal Equipment) devices. Since the power supply is also a DTE device, you must use a DTE-to-DTE interface cable. These cables are also called null-modem, modem-eliminator, or crossover cables.

The interface cable must also have the proper connector on each end and the internal wiring must be correct. Connectors typically have 9 pins (DB-9 connector) or 25 pins (DB-25 connector) with a “male” or “female” pin configuration. A male connector has pins inside the connector shell and a female connector has holes inside the connector shell.

If you cannot find the correct cable for your configuration, you may have to use a wiring adapter. If you are using a DTE-to-DTE cable, make sure the adapter is a “straight-through” type. Typical adapters include gender changers, null-modem adapters, and DB-9 to DB-25 adapters.

The cable and adapter diagrams shown below can be used to connect the power supply to most computers or terminals. If your configuration is different than those described, order the Agilent 34399A Adapter Kit. This kit contains adapters for connection to other computers, terminals, and modems. Instructions and pin diagrams are included with the adapter kit.

DB-9 Serial Connection If your computer or terminal has a 9-pin serial port with a male connector, use the null-modem cable included with the Agilent 34398A Cable Kit. This cable has a 9-pin female connector on each end. The cable pin diagram is shown below.
