If you have a full version of NI-VISA on your system, you can run NI-MAX or the VISA Interactive
Control utility. See the National Instruments documentation for information.
GPIB communications
The DMM6500 GPIB interface is IEEE Std 488.1 compliant and supports IEEE Std 488.2 common
commands and status model topology.
You can have up to 15 devices connected to a GPIB interface, including the controller. The maximum
cable length is the lesser of either:
•
The number of devices multiplied by 2 m (6.5 ft)
•
20 m (65.6 ft)
You may see erratic bus operation if you ignore these limits.
To use the GPIB interface your computer will need a GPIB card. Check the documentation for your
GPIB controller for installation information and where to acquire drivers.

Unpack and inspect
Make sure to handle the KTTI-GPIB carefully. Always grasp the card by the side edges. Do not touch
board surfaces, components, or areas adjacent to electrical contacts. Contamination from foreign
materials such as dirt, dust, and body oils can substantially degrade card performance.
To unpack and inspect your instrument:
1. Inspect the box for damage.
2. Open the box.
3. Remove the card and inspect for any obvious signs of physical damage.
4. Report any damage to the shipping agent immediately.
Installation
Slot covers must be installed on unused slots to prevent personal contact with high-voltage
circuits. Failure to recognize and observe standard safety precautions could result in
personal injury or death due to electric shock.
