RS-232 Troubleshooting:
If there is RS-232 connection problem, check the following:
 Computer and power supply must configure the same baud rate, parity,
data bits and flow control options. Note that the power configuration as a
start bit and a stop bit (these values are fixed).
 As described before in RS-232 connector, you must use the correct
interface cable or adapter. Note that even if the cable has the right plug, the
internal wiring may be wrong.
 Interface cable must be connected to the correct serial port on the
computer (COM1, COM2, etc.).
Communication Settings
Before communication, you should first make the following parameters of
power supply and PC matches.
Baud Rate: 9600 (4800/9600/19200/38400/57600/115200). You can enter the
system menu from the front panel, and then set the baud rate.
Data bits: 8
Stop Bits: 1
calibration (none, even, odd)
EVEN 8 data bits, have even parity
ODD 8 data bits have odd parity
NONE 8 data bits, no parity
Local Address: (0 ~ 31, the factory default setting is 0)
Parity=None Start Bit 8 Data Bits Stop Bit
5.2 USB interface
Use a Cable with two USB port to connect the power and the computer. All
power functions can be programmed via USB.
The USB488 interface functions of the power supply described as below:
 Interface is 488.2 USB488 interface.
 Interface Receiver REN_CONTROL, GO_TO_LOCAL, and
LOCAL_LOCKOUT request.
 Interface Receive MsgID = TRIGGER USBTMC order information, and will
pass TRIGGER order to the functional layer.
Power USB488 device functions described as follows:
 Devices can read all of the mandatory SCPI orders.
 Device is SR1 enabled.
 Device is RL1 enabled.
 Device is DT1 enabled.
5.3 RS485 interface
IT6726C power supply, via the RS485 interface, provides multi-unit control
function for up to 30 units (If connecting more than 10 units, add a 120Ω
resistor terminator to the last unit as shown in the figure below). Access the
menu tree Menu → SYST SET → COMM → RS485 to set the RS485
settings.
