The PC/104-GPIB is set at the factory with the jumper in place to
connect the logic ground of the PC/104-GPIB to its shield ground.
This configuration minimizes EMI emissions.
The PC/104-GPIB was tested for compliance with FCC and CE standards
with the shield ground connected to logic ground. Removing the jumper
might cause EMI emissions to exceed any or all of the applicable
standards.
If your application requires that logic ground be disconnected from
shield ground, follow these steps:
1. Refer to Figure 2-7 to locate the shield ground jumper W5 on the
PC/104-GPIB.
