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.. utp utp fibre utp utp +-----+ +-------+ +-------+ +-------+ +-----+ +-----+ | w/s |---| demon |----|chipcom|******|chipcom|---|demon|---| w/s | +-----+ +-------+ +-------+ +-------+ +-----+ +-----+ ^ ^ ^ ^ ^ ^ ^ ^ 10BT 4 port 10BT Fib Fib 10BT 4 port 10BT device repeater port port port port repeater device thanks in advance for the help
