Contacts

NEO can use the modem handshake signals present in a full-function serial line to detect switch closures and openings which can cause shortcuts to be fired. NEO can respond to switch events from a local serial port or a networked serial port using the Simple Network Management Protocol (SNMP).

To set up contact events, specify the “Com Port” to use. There are 4 signals that can be detected [Clear To Send (CTS), Data Set Ready (DSR), Ring Indicator (RI) and Carrier Detect (DCD)] and each can be linked to a shortcut for a closure event and/or an opening event.  Additional com ports can be configured by using the “Add” button.

The following diagram shows an example of how to wire switch contacts to a 9-pin serial port connector.
