78 ADLINK DIN-68H
All jumpers on DIN-68H are used for the setting of pull-up or pull-
down resistor termination. The proper termination setting can
reduce signal refection during high-speed data transfer. The below
diagram is the schematic of AF6, AF7, and D0 to D31. The default
jumper setting of DIN-68H is set to 50Ω pull-down termination.
When you change the jumper setting to 5V pull-up termination,
you have to apply +5V power to +5V
IN
connector. If you don't want
to set termination on specific channels, just remove the corre-
sponding jumpers on the DIN-68H..
