5.2 USB Interface
Connect the load and the computer using a cable with two USB interfaces
(each end). All functions of the load can be programmed via USB.
The functions of load USB488 interface are as follows:
 The interface is 488.2 USB488 Interface.
 The interface receives requests of REN_CONTROL, GO_TO_LOCAL and
LOCAL_LOCKOUT.
 The interface receives the command MsgID=TRIGGER USBTMC and
conveys the TRIGGER command to the functional layer.
The functions of load USB488 device are as follows:
 Capable to read all common SCPI commands.
 SR1 enabled.
 RL1 enabled.
 DT1 enabled.
5.3 GPIB interface
Firstly, connect load GPIB interface and computer GPIB card through IEEE488
bus and ensure sufficient contact. Tighten them with screws. Set address. Load
address range: 0 to 31. Press [Shift] + numeric key 8 (System) to enter system
menu functions. Press Left/Right key to find Communication. Select GPIB and
set address. Input address and press [Enter] for confirmation. The load works
by setting GPIB address on front board. GPIB address is saved in NVM.
