RS-232 Troubleshooting:
If there is RS-232 connection problem, check the following:
1. 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).
2. 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.
3. 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: (SIG,MUX)
SIG a single instrument is connected to the communication
MUX 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 ～30, default set is 0）
Local Address: (0 ~ 30, the factory default setting is 0)
Parity=None
Start Bit
8 Data Bits
Stop Bit
4.2 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 Receive REN_CONTROL, GO_TO_LOCAL, and
