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
6.2 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.
