GPIB-PRL User Manual
Step 3. Configure the Operating Parameters
The GPIB-PRL is shipped from the factory configured to operate in G mode
and set to the GPIB primary address of 5. If you wish to use the GPIB-PRL in
P mode or wish to change the GPIB primary address, it is necessary to open
the unit and set the configuration switches. To change the configuration
switches follow these steps:
1.
Disconnect power to the unit and disconnect any cables that may be
connected to the unit.
2.
Unscrew the two screws on the opposite sides of the rear panel.
3.
Grab the rear panel bezel and pull it straight away from the rest of the
unit. The card should slide out the back of the enclosure.
4.
Locate the configuration DIP switch (U22) on the printed wire board.
5.
Set the switches for the desired mode of operation. Refer to Set
Configuration Switches later in this manual.
Caution:
Most of the circuitry in the GPIB-PRL uses advanced
CMOS technology and can be damaged by static
electricity. Avoid touching any of the components and
take any necessary CMOS handling precautions.
6.
Close the unit and reinsert the screws removed in Step 2.
