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. 
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: SIGNAL, MUX 
SIGNAL (Single connection mode) 
MUX (Multiple connection mode) ADDR: Local address (0 to 30
, the 
factory default setting is 0) 
Start Bit    8 Data Bits  Parity=None  Stop Bit 
 
1.6.2 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. 
  Interface Receiver REN_CONTROL, GO_TO_LOCAL, and 
LOCAL_LOCKOUT request. 
  Interface receive MsgID = TRIGGER USBTMC order information, 
and will pass TRIGGER order to the functional layer. 
Power USB488 device functions described as follows: 
  Devices can read all of the mandatory SCPI orders. 
  Device is SR1 enabled. 
  Device is RL1 enabled. 
  Device is DT1 enabled. 
1.6.3 GPIB interface 
First, Connect the GPIB interface on the power supply and the GPIB 
card on computer via IEEE488 bus, must be full access and tighten the 
screws. Then set the address, the address range of the power : 0 to 30, 
can set by the function key on the front panel, press the +
  key 
to enter the system menu function, find the GPIB address setting by 
button, type the address, 
key to confirm. GPIB address is 
stored in nonvolatile memory line.
