Remote communications interfaces
You can choose from one of several communication interfaces to send commands to and receive
responses from the DMM6500.
The instrument automatically detects the type of communications interface (LAN, USB, GPIB,
RS-232, or TSP-Link) when you connect to the respective port on the rear panel of the instrument.
The GPIB, RS-232, and TSP-Link options require an optional accessory card. In most cases, you do
not need to configure anything on the instrument. In addition, you do not need to reboot if you change
the type of interface that is connected.
You can only use one communications interface to control the DMM6500 at a time. The USB
connection takes precedence over LAN connections. For other communications interfaces, the first
interface on which the instrument receives a message takes control of the instrument. If another
interface sends a message, that interface can take control of the instrument. You may need to enter a
password to change the interface, depending on the access mode.
