spacing. The sensors can be held in place by tape over the
bottom of the hole. If you must glue them in place, be sure to
use a water based, clear drying glue.
Connect the sensor cables to the TrainSpeed 4 unit on
connectors J1, J2, J3 and J4, being sure to align the red stripe
on the cable to the pin 1 marking on the TrainSpeed board (see
figure 1).
Do not use staples to hold the cables in place as they can cut
the insulation and cause shorts. If you must anchor the cables
to the benchwork, staple a cable tie to the benchwork and then
wrap the cable tie around the sensor cable.
You now need to configure the TrainSpeed’s jumpers to use
the sensor spacing selected from the previous tables. The
factory configuration is set to 1/100 of a mile (or Km). Using
this table set the option jumpers for the chosen sensor spacing.
