The ODMB is a circuit card with connectors wired in parallel whereby up to 12 OD or DCCOD cards can be inserted. Using the ODMB cuts down on the wiring requirements and also enables the detectors to be distributed around the railroad. The power supply connections to the ODMB are slightly different depending upon whether you are using ODs or DCCODs. If more than 12 detectors are desired at any location, multiple ODMBs can be connected together or you can add on a section from an ODMB4 card.

All circuit boards come unassembled and less components. All holes are drilled and all circuit traces are tin plated for easy soldering. Where double-sided boards are provided, all feed through holes are plated-through. The SMINI, SUSIC, RS485, DIN32, DOUT32 and PGCC boards have solder masking on both sides, silk screen legend on component side and are factory tested against shorts and open circuits.
