Set the NEC-GPIB/TNT Shield Ground Configuration
The NEC-GPIB/TNT is set at the factory with the jumper in place to connect the logic ground of the
NEC-GPIB/TNT to its shield ground. Thisconfiguration minimizes EMI emissions.
Note
The NEC-GPIB/TNT was tested for compliance with FCC 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.
Most users do not need to change the shield ground configuration. If you feel you must disconnect
the logic ground from shield ground, follow these steps:
1. Locate the shield ground jumper W1 on the NEC-GPIB/TNT. (View the NEC-GPIB/TNT Parts
Locator Diagram.)
2. Remove the jumper and place it across only one of the jumper pins, as shown in the following
figure.
