Getting Started
A unique device address should be assigned to each device on the bus. No
two devices should share the same device address.
No more than 15 devices can be connected to any one bus.
Only one device should be connected for every 6 feet (2 meters) of cable used.
No more than 65 feet (20 meters) of cable should be used to connect devices
to a bus.
At least two-thirds of the devices on the network should be on while using
the network.
Connect the devices on the network in a star or linear con fi guration. Do not
use loop or parallel con fi gurations.
To Change GPIB Address
Settings
Your power supply must have a unique device address to function properly. The
default setting for the GPIB con
fi guration is GPIB Address 1. If there is more
than one GPIB instrument on the bus, you will need to change the default setting
on the power supply. To change the GPIB address settings, do the following:
1. On the instrument front-panel, push the Shift button and then the 1 button to
access the menu.
2. Press the down arrow key until you see System and then press the Enter
button.
3. Press the down arrow key until you see Address and then press the Enter
button.
4. You can now change the address of your GPIB port. This will set the GPIB
address on an attached TEK-USB-488 Adapter.
The power supply is now set up for bidirectional communication with your
controller.
Command Timing
The average time it takes to both send and receive every command is
approximately 20 ms. In the case of more complex commands, more time may
be required to complete transmission.
