Device Net question


I have a remote device net scanner SST-EDN-1 that I want to use to connect to a single chiller that is located ~40' away. this chiller has an integrated Device net card installed. My question is since I have no drops can I get away with a single 15m cable between both devices with two tees at the SST-EDN side, one for 24VDC and one for a terminator? Trying to eliminate a hub and I'm being told with only one device on the network I can have a cable length of 330'.
Rockwell has some good information on setting up DeviceNet networks, do a search in their literature library for DNET-UM072. Otherwise provide more information if you still need help: What cable you are using? What baud rate? Where is your second terminating resistor?
