make certain that the included terminator plugs are connected properly at the input bus of the
master unit and the thru bus on the last unit in the network as the following illustration

network system have a unique ID number assigned. In addition, there can be only one
master unit assigned for the network to function properly.

one of the utility menu will show all device ID number currently in the DriveRack™ network

modem cable be used.
