SC-2057
The SC-2057 has one jumper, W1, shown in Figure 10-5. Jumper W1
connects the shield of the SH96-96 cable to the mounting rack or the digital
ground of the VXI-DIO-128 to the mounting rack.
Figure 10-7.
SC-2057 Shield Jumper Location
Setting jumper W1 to the position between the two labels CABLE SHIELD
and CHASSIS GND connects the shield of the SH96-96 cable to the four
metal standoffs. If the board is installed in the 19-in. rack, this setting
grounds the shield of the SH96-96 to the rack. If jumper W1 is positioned
between the two labels CHASSIS GND and DIGITAL GND, the digital
ground of the VXI-DIO-128 is connected to the four metal standoffs. If the
adapter is installed in the 19-in. rack, this setting grounds the digital ground
of the VXI-DIO-128 to the rack. Removing jumper W1 will isolate the
shield of the SH96-96 and the digital ground of the VXI-DIO-128 from the
rack.
The SC-2057 is shipped from the factory with the jumper W1 set to the
position between the CABLE SHIELD and CHASSISGND. Figure 10-8
shows the ground settings for SC-2057 jumper W1.
