    Danfoss FC100 on Johnson FC bus?

    Hello all,

    I have a couple danfoss drives I'm trying to get on my network. The drives have the BACnet interface card installed. I followed the steps in the literature for BACnet set up but once the drive is physically connected to the network it seems to wipe out the entire network on that trunk the other devices go offline in respect to the network. The addresses are all different that's the first thing I checked.

    Also I have two revisions of the literature the older rev has all the of the BACnet wires hooked up +,- and com, in the newer revision it only shows two of the three hooked up the +,-

    Typo? seemed strange.

    Thanks in advanced.
