VXi VT1529A/B 사용자 설명서

The back of the terminal module PCB (printed circuit board) provides surface mount 
pads which can be used to add serial and parallel components to any channel's signal 
path. Figure 2-17 shows additional component locator information (see the 
schematic and pad layout information on the back of the terminal module PCB). 
Figure 2-18 shows some usage example schematics.
