J52 Box Out Connections for the Model 494.43 Multibox Board
The J52 Box Out connector provides an interface for connecting multiple MTS
controller chassis together to allow sharing of station interlock status and a
master synchronization clock.
Last controller jumper
The last controller box in a chain must have a jumper plug (MTS part number
100-079-126) on its J52 Box Out connector. This jumper allows the return of the
composite station interlock signal for all controllers in the chain to monitor.
Note If there is only one controller, a jumper is still required on its Box Out
connector.
Cable specification
Use MTS cable part number 056-534-1xx.
