In this case you need to use a splitter cable . As an example of this: supposing that you wanted to develop a system that used two external analogue sensors. The Sensor board only has the capability for one external analogue sensor, so you need to use a splitter cable and the patch system to make the appropriate connections. The resulting system would look something like this:  The splitter cable allows you to connect one upstream port to two downstream ports using IDC (Insulation Displacement Connector) connectors and ribbon cable. You can see that the analogue sensor input on the top board is the default connection: bit 3. On the lower board the link blocks are moved to the "patch" position and a small wire is used to connect the second analogue sensor to bit 2. The resulting system allows you to connect one analogue sensor to bit 3 and the other to bit 2 on the upstream board. (:nl:)(:table style="clear:both":)
