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 on the 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
MODE:
（

multiple sets of instrument communication with PC at the same time, in this
situation, instrument address must be set to distinguish among all the units(address 0
