Step 3. Configure the Operating Parameters
The GPIB-BUF is shipped from the factory configured to operate at a GPIB
primary address of 5 with the SRQ-on-empty function disabled and device
clear recognition and pass through enabled.
The address specified on the configuration switches should match the GPIB
address of your target device. If the addresses do not match, you must
either change the primary address of your target device or change the
primary address of the GPIB-BUF so that they correspond.
To change the primary address of your target device, refer to the user
manual of the device.
To change the GPIB-BUF primary address, the SRQ-on-empty function, or
the device clear response method, you must open the unit and change the
configuration switches. The following steps describe how to change the
configuration switches.
1. Disconnect power to the GPIB-BUF and disconnect any cables attached
to the rear panel.
2. Remove the two screws on the opposite sides of the rear panel.
Warning: Most of the circuitry in the GPIB-BUF uses advanced
CMOS technology and can be damaged by static electricity.
Avoid touching any of the components and take any
necessary CMOS handling precautions.
3. Grasp the rear panel bezel and pull it straight away from the rest of the
unit. The board should slide out the back of the enclosure.
4. Locate the configuration DIP switch (U38) on the printed circuit board.
5. Set the switches for the desired configuration, as described in the
following section, Set Configuration Switches.
6. Close the unit and reinsert the rear panel screws.
