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 HP 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.
