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.

To specify a network interface for CAB control

1. On the Network screen, under CAB Control Interface, select a network interface for the CobraNet network.

   The details for the Local Area Connection interface are shown first, followed by the details for Local Area Connection 2.

2. Click Set to confirm the action.

   You will be asked to log on.

3. Specify your username and password. The default username is superuser; it has no password.
4. Navigate to the Special screen.
