5.2 Communication between Power Supply and PC
Before putting the instrument into remote operation, make sure that the baud rate, parity bit and communication
address settings on the power supply and computer side are identical, otherwise communication will not be
possible.
1． Address Range is 0 to 30. Default setting is 0.
2． Baud rate: 4800,9600,19200 and 38400 are selectable, default setting is 9600
3． Parity and Data bits： None/8 bits (default setting)
Even/8 bits
Odd/8 bits
4． Stop bits：1 (fixed)
5． Start Bits: 1 (fixed)

DB9 Interface Details
The DB9 connector in the rear panel of the power supply provides a TTL level signal .It can be connected to a
standard PC interface via the IT-E131 or IT-E132 isolated communication cable.
Note: Setting of the address is optional. It is not required to communicate with the instrument. The
address can be set from the front panel and is stored in non volatile memory. This feature is
