Figure 2-53 "GPIB" Tab Interface 
 
The load supports GPIB (extended from the USB-GPIB interface converter), USB, 
RS232, and LAN. Remote control can be realized via these interfaces. When you 
select GPIB, RS232, or LAN, please set the parameters for the interface first. 
 
 
 
Set the GPIB address 
 
Before using the GPIB interface, use the USB-GPIB interface converter to extend the 
GPIB interface, and then use the GPIB cable to connect the load to the PC. 
 
Procedures for setting the GPIB address are as follows: 
(1) Press Interface to enter the communication interface tab. By default, "GPIB" is 
selected and it is highlighted. 
 
(2) Use the numeric keys to set the GPIB address. 
 
(3) Press OK to confirm it. 
 
The GPIB address is an integer ranging from 0 to 30. By default, it is 2. The setting is 
stored in the non-volatile memory, which will not be affected even if you restore the 
load to its factory defaults. 
 
  W
hen the load is connected to power source, you can also connect/disconnect 
USB and LAN interfaces. 
  GPIB, USB, RS232, and LAN interfaces cannot be used synchronously. Each 
time, only one type of interface can be used.
