3: Using a remote interface DMM6500 6½ Digit Multimeter
3-2 DMM6500-900-01Rev. A / April 2018
Supported remote interfaces
The DMM6500 supports the following remote interfaces:
• GPIB: IEEE-488 instrumentation general purpose interface bus
• Ethernet: Local-area-network communications
• RS-232: Serial communication data standard
• USB: Type B USB port
• TSP-Link: A high-speed trigger synchronization and communications bus that test system
builders can use to connect multiple instruments in a master-and-subordinate configuration
The GPIB, RS-232, and TSP-Link interfaces require an optional communications accessory card to
be installed in the instrument. Accessory cards include the KTTI-GPIB, KTTI-TSP, and KTTI-RS232.
For details about TSP-Link, see "TSP-Link System Expansion Interface" in the Model DMM6500
Reference Manual.
The rear panel connections for the remote communication interfaces are shown in the following
figure.

LAN communications
You can communicate with the instrument using a local area network (LAN).
When you connect using a LAN, you can use a web browser to access the internal web page of the
instrument and change some of the instrument settings. For more information, see
Using the web
interface (on page 3-15).
The DMM6500 is a version 1.5 LXI Device Specification 2016 compliant instrument that supports
TCP/IP and complies with IEEE Std 802.3 (ethernet LAN). There is one LAN port (located on the rear
panel of the instrument) that supports full connectivity on a 10 Mbps or 100 Mbps network. The
DMM6500 automatically detects the speed.
The DMM6500 also supports Multicast DNS (mDNS) and DNS Service Discovery (DNS-SD), which
are useful on a LAN with no central administration.
