Specifications

Baud Rate
You can select one of the following baud rates from the front panel, which is stored in non-volatile
memory:
2400 4800 9600 19200 38400 57600 115200
The default baud rate is set to 9600.
RS-232 Returned String Format
For non-query commands: OK + LF + CR;
For queries: OK + LF + CR + returned value + LF + CR + OK + LF + CR.
Note: Using RS-232 interface to get the voltage or current read back value, a minimum 50 milliseconds
delay must be added to the application program.
RS-232 Troubleshooting
If you are having trouble communicating over the RS-232 interface, check the following:
x The computer and the PD unit must be configured for the same baud rate, parity, number of data
bits, and flow control options. Note that the PD unit is configured for 1 start bit and 1 stop bit
(these values are fixed).
x The correct interface cables or adaptors must be used.
x The interface cable must be connected to the correct serial port on your computer (COM1, COM2,
etc.).
ETHERNET CAPABILITIES OF THE POWER SUPPLY
(ETHERNET OPTION ONLY)
The power supply provides an Ethernet programming interface as optional. All SCPI commands are also
available through Ethernet programming. When the Ethernet interface is selected, the GPIB interface and
RS-232 interface should not be operated.
Obtain Network Information
To connect the power supply to the network, you only need a network cable with RJ-45 connector. No
transceiver is necessary. However, you need to obtain the following information from the power supply
unit and your network administrator:
1. Power supply Ethernet MAC Address:
It’s a twelve digits string that unequally identifies the power supply unit. It can be obtained from the control
board.
2. Network information:
1) DHCP server enabled? Yes or no.
2) Power supply IP address:
. . .
3) Gateway IP address: . . .
4) Subnet mask: . . .
