1175.0. "DEMON question" by KAOFS::R_YURKIW (reward those who bring bad news!!) Wed Jun 29 1994 11:53

    I have a question regarding the DEMON 4 port ethernet hub. Is this
    device a full, half or no repeater. I have a situation that the
    customer wants a 10BaseT connection to a remote area fo the plant and
    he wants to keep his wiring twisted pair.
    
    #1) He has a central hub (Chipcom I believe) with 10BaseT repeater cards
    in them. From here I am thinking of going out into the plant some 250ft
    to a DEMON and then another couple hundred feet to the workstation. I
    think this is ok by itself but can someone confirm this.
    
    
    #2) the larger picture here is that we effectively have two of these
    arrangements coming off two separate chipcom hubs that are
    interconnected by a synchronous fibre link. (see diagram). I am not
    sure if this breaks repeater rules or not. Can someone help..
