Extended Communication Interface
The GPIB communication interface can be expanded. The user should know the GPIB
address when using PC with GPIB to remote programming the Electronic Load. Every
device that connects to the GPIB interface will be assigned a unique address.

resistance increases to 5V, low level <0.6V, loading current = 10mA.
the user can use the input signal to control Load ON/OFF externally.
When DI1 and DI2 are both set to External Load ON/OFF, both
signals need to be HIGH to Load OFF and on the contrary both
signals need to be LOW to Load ON.
When DI1 (or DI2) is set to Remote Inhibit and Low, all channels in
the Electronic Load are Load OFF and a message of REMOTE
INHIBIT will appear. If this protection is not cleared, even the DI1 (or
DI2) is High, Load on cannot be executed. DI1 and DI2 are for
communication control and the action time should be less than 5ms.
