6 Channel Hub

The 6 Channel Hub allows you to connect six different 1-wire “sub-networks” in a star topology. (See our discussion of network topology for more information on hubs.)

The 6 Channel Hub has eight RJ45 connections. 6 Channel Hub One of the connections is a 1-Wire “in”, which should be connected to a Serial Adaptor or USB Adaptor using one of our Adaptor Cables, or your own adaptor cable. One of the connections is a 1-Wire “out”, and the six additional connections are the 6 hub channels. Each of the six channels, as well as the “out”, can be connected to a 1-wire sub-network using standard network cables. The “out” is a pass-through to the “in”, with the addition of supplemental power. The other six channels consist of three main channels and three auxiliary channels that are controlled by the three DS2409 chips. It does not matter which of these connections are used for the various parts of your 1-Wire network. You will need to specify, in your software, which of these channel is used for each of your devices. (Please see your software documentation for further details on how to specify hub channels.)

The 6 Channel Hub can optionally add supplemental power to the six channels and to the “out”, acting as a Power Injector. This adds regulated (5 volts) and unregulated (15 volts if using our Power Adaptor, or the voltage supplied by your power adapter) supplemental power to unused wires on the Cat 5 cable. Supplemental power is controlled by two jumpers on the board. Each jumper is clearly marked. The board is shipped with jumpers connected, providing both regulated and unregulated power to all outputs. If you do not want the hub to provide supplemental power, you can remove one or both of the jumpers. This will disable the appropriate supplemental power from all outputs; there is no way to control power output individually for each channel. Please see the description of our Power Injector for more details of power on the 1-Wire network.

If you need to know the actual wiring of our RJ45 connectors, please refer to our instructions on how to wire the cable connectors.

The 6 Channel Hub requires power, even if you do not use the supplemental power feature. It must be connected to a mains outlet through an AC power adaptor that provides 12-24 volts DC, 500mA, through a 2.1mm center positive connector.
