Frequently Asked Questions
Does it work without a Tracer SC+?
No. The bridge integrates Comm3 and Comm4 devices into a Tracer SC+ system; it is not a standalone converter.
Where is the missing screw?
At one terminal block position next to the BACnet serial connector. The terminal can be used with a replacement screw of the appropriate size.
How is it set up?
With existing Tracer Summit software, after a service pack upgrade.
Will it replace a bridge board labeled BRD NO. 50100956?
Yes, if your old board reads 50100956 Rev A. This board carries that label beside its status LEDs, so match the number before you swap it. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
Five terminal groups line the bottom edge, BACnet at one end and COMM5 at the other, and the whole strip is short exactly one screw. Find its match in the parts drawer before the board goes in.
