Pari-mutuel Displays
Each pari-mutuel display model requires power, while one display may receive signal
and re-drive it to other displays (refer to Figure 31 for an example of re-driving signal).
All pari-mutuel displays are composed of two sections. In order for power and signal to
reach both sections, an interconnect cable from the primary driver in one section must
be connected to the driver in the other section. The location of these drivers varies, but
the connectors always include a 5-pin plug labeled P50 and a mating jack labeled J50 .
Refer to the schematic drawings in the service manual for detailed driver interconnect
diagrams.
Note: Since the PM-2101 has two sections but only one driver, it requires individual
digit harnesses to be routed from the top section down into the bottom and
connected to the appropriate jacks in the driver. Refer to the component
location drawing (attached to product specification sheet listed in Appendix A )
for the proper digit output numbers of the top digits.
