Secondary Serial Interface (AUX Interface) on TGW-100 DIN-Rail
On the TGW-100 DIN-Rail-version, the AUX interface socket is located on the lower
side of the unit. This interface allows the implementation of special applications, e.g.,
switching of the data-flow through this interface by a command, or feeding data from a
predefined ISSI to this port rather that to COM.
This secondary interface is provided through a 6-pin RJ-12 connector and equipped
default with an RS-232 interface. The unit can be ordered optional with an RS-485
interface (RS-422 is not possible on the AUX port).
