PON
Power On. Power has been turned off and on since the
last time the event register was read or cleared
Query status register provide some information of the power, such as
over voltage, over temperature, over current, you can also monitor the
change of the constant current and voltage status via the register, for
example, data bit 0 is the constant current mode of the power supply,
data bit 1 is constant voltage mode of the power supply, and so on.
Bit
Definition
0
Voltage
The power supply is/was in the constant current mode.
1
Current
The power supply is/was in the constant voltage mode.

Status byte register records the information of other registers. The query data is
temporally stored in the output buffer of the power supply, and feedback to
customer through BIT4 bit. The data bits in Status byte group will not be
latched, when the information in event register is changed, the correspo0nding
bit in status byte register will subsequently be changed.

QUES
One or more bits are set in the questionable status
register (bits must be “enabled” in the enable register).
4
MAV
Data is available in the power supply output buffer.
5
ESB
One or more bits are set in the standard event register
(bits must be “enabled” in the enable register).

1.7 Remote Operation
IT6700 series power supply is provided with three communication interfaces to
communicate with a computer for selection, including S232, USB, RS485 and
GPIB. IT6722A has not standard GPIB communication interface.
RS232 interface
There is a DB9 connector at the rear of the power supply, when connect to
computer, you need to select a cable with COM port on both side; to active
communication, you need to enable the settings in menu to be the same with
