Table 7: Pin configuration of the GPO connector (DB-25M)
Connections using general-purpose inputs (GPI’s)
The DB-25 connector labeled GP IN connects the matrix to eight local general-
purpose inputs (GPIs).
An external logic device (such as an external foot switch, a panel-mounted switch,
or the logic output of some other device) can be connected to the GP IN connector.
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
programmed from the EHX software.
A shielded cable should be used.
