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 Utility  I/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.
