5. Digital I/O
Female DB-25 connector. Use a cable equipped with a male DB-25
connector (Keithley Instruments part number CA-126-1A; L-com part
number CSMN25MF-5).
Pins provided:
â–ª Fourteen digital input or output pins
â–ª Seven GND pins
â–ª Three +5 V pins
6. IEEE-488

9. USB port
This USB-2.0 receptacle (Type B) located on the rear panel is used to
connect the instrument to a computer. You can use this connection to send
commands to the instrument.
10. Ground
