To Set the RS232 Parameters

Connect the RS232 interface to the PC or data terminal equipment (DTE) using

RS232 cable and set the interface parameters (baud rate, parity bit, etc.) that match

the PC or terminal equipment. At this point, you can control the instrument remotely.

RS232 Interface


Press UtilityI/O Config RS232 to open the RS232 parameter setting
interface.

1. Baud Rate

Press Baudrate to select the desired baud rate (4800, 7200, 9600, 14400,

19200, 38400, 57600, 115200 or 128000, the unit is Baud).

2. Data Bit

Press Data Bit to select the desired data bit (5, 6, 7 or 8).

3. Stop Bit

Press Stop Bit to select the desired stop bit (1 or 2).

4. Parity Bit

Press Parity Bit to select the desired parity mode (“None”, “Odd” or “Even”).

5. Hardware Flow Control

Press Flow Ctrl to enable or disable the hardware flow control.

This power supply uses RTS/CTS hardware flow control mode. The instrument

monitors the status of the CTS pin. When the status is “True”, the instrument

sends data; when the status is “False”, the instrument stops sending data. The

instrument sets the CTS pin to “False” when the input buffer area is almost full

and sets the CTS pin to “True” when the input buffer area is available again.
