5 Remote Operation
Users can program the power supply by using the SCPI (Standard Commands for Programmable
Instruments) commands over the TTL remote interface (via USB virtual com with IT-E132B).
Communication cables
The power supply has a DB9 connector on the rear panel that allows remote communication via
the IT-E132B adapter.
Do not connect the DB9 connector to a standard RS-232 serial port.
Doing so may damage the instrument. The instrument outputs TTL
signal levels only, and must be used with IT-E132B adapter to
connect to a USB port (virtual com) on a PC.
USB to TTL Adapter IT-E132B
Use the IT-E132B USB to TTL adapter to connect a PC to the instrument for remote
communication.
Connect the INSTRUMENT side of the adapter to the DC load DB9 connector. Connect the
COMPUTER end to a USB port on your computer.
When connected, the computer will automatically install the appropriate drivers (For Windows®
7 or above).
Upon successful installation of the driver, the USB connection will be registered as a virtual COM
device. It can be accessed and control via the assigned COM port (This can be verified in
“Device Manager”) the same way as you would with RS-232 serial interfaces.
Note: The RMT indicator will appear on display when the power supply is successfully
connected to a PC remotely through any remote interface. Keys on the front panel will be
locked until the instrument is in LOCAL mode. To return to LOCAL mode from the front
panel, press the key. The RMT indicator will disappear when the instrument is in
LOCAL mode.
