RD022 splitter
RD022 cascadable splitter for three (3) digital interfaces/sensors, splits the 1 Wire interface into 3 channels. The splitters may be cascaded.
The RD022 splitter has RJ12 sockets on both shorter sides. These sockets use 1-Wire BBO standard and one of them shall be connected to one of free black 1-Wire BBO sockets inside XBB006 using Reversed cable. The other one can be used to connect the next RD022 splitter using Straight cable. Both pinouts are described in 1-Wire BBO and ICU pinouts chapter.
There are also 3 RJ12 sockets on one of the long sides. They have ICU 1-Wire pinout and can be used to connect digital sensors or interfaces.
An example of XBB006 with 2 RD022 splitters, one XBT006 PT100 interface with PT100 temperature sensor.
Straight cable
The straight 1-Wire cable has 2 RJ12 plugs with pin 1 on one side connected to pin 1 on the other end and so forth. The RJ12 tabs are on the opposite sides of the cable as shown below:
The straight cable is used to connect RD022 splitter to another RD022 splitter.
Reversed cable
The reversed 1-Wire cable has 2 RJ12 plugs with pin 1 on one side connected to pin 6 on the other end and so forth. The RJ12 tabs are on the the same side of the cable as shown below:
The reversed cable is used to connect XBBO006 1-Wire BBO socket with 1-Wire BBO socket of the RD022 splitter.
