Interfacing with a CAB device
The nTouch 180 unit can interface with CAB devices, including the CAB 4n. This in turn
allows control of external devices via the GPIO port, relays, RS-485 port etc. on the CAB.
The nTouch 180 unit has two Ethernet ports, allowing a number of different configurations. In
the example below, the nTouch 180 unit can communicate with the CAB via the first of its two
Ethernet ports, labeled Local Area Connection in the web interface.
In the next example, in order to communicate with the CAB, data must be sent via the second
Ethernet port, labeled Local Area Connection 2 in the web interface.
You need to specify which Ethernet port is to be used for communicating with CAB devices on
the network.
