Jumpers are provided to select between differential and single-ended for each input. Differential mode is with the jumper towards the center of the board, single-ended is with the jumper away from the middle. When connecting single-ended inputs, the signal should be connected to the "+" input pins of the 37-pin CPC connector. No connection to the "-" terminal is needed. Jumper assignment is as follows :
Jumper # Signal
JP1 A 0
JP2 B 0
JP3 Z 0
JP4 U 0
JP5 V 0
JP6 W 0
JP7 A 1
JP8 B 1
JP9 Z 1
JP10 U 1
JP11 V 1
JP12 W 1
JP13 A 2

The mating connector AMP/Tyco 206305-1, Digi-Key A1359. The cable clamp is AMP 206512-5, DK A32502. The signal pins are AMP 66102-8, DK A25107CT. The power pins are AMP 66361-4, DK A1650. The AMP crimping tool "Service Tool I" is AMP 696202-1. Digi-Key doesn't have this in their catalog, but can get it at a high price. The best price I have found is from Newark Electronics.
