Interface Cable
In order to command the power supply over the remote interface, you must
connect it to a computer terminal.
Usually, the computer terminals are DTE (Data Terminal Equipment). The
power supply is also DTE, so you need a DTE to DTE interface cable. These
cables are called null-modem or crossover cables.
There are 2 types of serial connectors: DB-9 and DB-25. The power supply has
a male DB-9 connector.
Here is cable pin diagram for DB-9 connector:
The rest of the pins are not connected.
If the serial port from your PC has a DB-25 connector, you must use a DB-25
to DB-9 adapter.
