Notes for GPIB installation
When the programmable power supply is set up with a GPIB system, please
check the following things:
z Only a maximum of 15 devices can be connected to a single GPIB bus.
z Do not use more than 20m of cable to connect devices to a bus.
z Connect one device for every 2m of cable used.
z Each device on the bus needs a unique device address. No two devices
can share the same device address.
z Turn on at least two-thirds of the devices on the GPIB system while
using the system.
z Do not use loop or parallel structure for the topology of GPIB system.
Computer’s Connection
A personal computer with a GPIB card is the essential facilities in order to
operate the programmable power supply via GPIB interface.
The connections between power supply and computer are following:
I. Connect one end of a GPIB cable to the computer.
II. Connect the other end of the GPIB cable to the GPIB port on the
programmable power supply.

The GPIB connection testing
If you want to test whether the GPIB connection is working or not, you can
send a GPIB command from computer. For instance, the query command
*idn?
should return the Manufacturer, model number, serial number and firmware
version in the following format:
GW.Inc,PSM-2010,A000000,FW1.00
If you do not receive a proper response from the power supply, please check
if the power is on, the GPIB address is correct, and all cable connections are
active.
