Clear-Com HX System Frames - Manual (Page 44)

6.7 General Purpose Inputs (GPIs)
You can connect an external logic device (such as an external foot switch, a panel-mounted
switch, or the logic output of some other device) to the connector labeled GP IN on the rear
of the Eclipse HX matrix frame.
When the external logic device is activated, it sends a control signal into the matrix to
perform one of several preset functions, such as turning an intercom panel’s microphone on
or off, muting a microphone’s output, or turning a panel’s speaker off. The function to
perform and the panel upon which it is performed is configured using the Eclipse
configuration software (EHX).
The DB-25 connector labeled GP IN on the rear of the Eclipse matrix connects to eight local
general-purpose inputs. The GPIs are opto-isolated. Shielded cable should be used to
connect GPIs.
