Besides the front panel control, DMM supports RS-232 serial interface and GPIB parallel interface for
remote control. You can use only one interface at a time. Standard Commands for Programmable
Instruments (SCPI) is fully supported by the RS-232 and GPIB interfaces, however they use different
hardware configurations and communication protocols.

Selecting an interface
Model DMM multimeter supports three built-in interfaces:
USB device interface
RS-232 interface(optional)
GPIB bus interface (optional)
You can use only one interface at a time. The factory interface selection is the RS-232 interface. You can
select the interface from the front panel. The interface selection is stored in non-volatile memory. It does not
change when power has been off or after a remote interface reset.

USB
You can operate the USB device interface as if it's a RS232 interface from the computer, after the USB
driver is installed. All the instrument setups for RS232 interface are applicable for the USB interface (or
virtual RS232 interface). Please refer to RS-232 setup and operation.
5.1.2
RS-232
You can connect RS-232 interface with a computer. Some considerations will draw your attention:
You must define the baud rate
You must use the SCPI programming language
