Binary Inputs and Outputs
What Is Binary I/O?
The Binary I/O ports are routing objects cooperating with the binary ports on the
Audio/IO/Relay board. Each port consists of a relay and a detector. Thus, the ports can
be used both for relay switching and relay state detection. The port has only a weak
current source and is not intended for switching door locks and similar equipment. If
completed with an appropriate external source, however, the port can be used for this
purpose too.
Binary Ports
The Audio/IO/Relay board can have four or eight binary ports. Each of them can be
used in the Output (switch), Input (detector) or bi-directional mode (switch and
detector). The function of each port also depends on the jumper hardware setting. For
available modes refer to the Hardware Manual, Chapter
.
The
setting contains a non-programmable Pulse filtering [ms] parameter, which is set to
a fixed value of 100ms. This means that changes on the input are detected every
100ms even if they came more frequently. The parameter helps protect the PBX
against overload.
The binary ports cannot be used as standard PBX virtual ports and should be assigned
to a specific routing object of the Binary I/O type. Each binary port can be assigned to
multiple Binary I/O routing objects.
Binary I/O Routing Object
The Binary I/O routing object can be set as a switch or a detector. The following
parameters are common for both the modes.
Name - displays the name of the selected object only. It cannot be directly
configured here.
Binary I/O - assigns an Audio/IO/Relay board source to a selected object.
Direction - defines whether the selected routing object controls the binary port
switch or detector.
Switch Setup
Switch status - this parameter displays the current status of the switch/relay
(Active, Inactive, Unknown). With the
option, the assigned binary port
Unknown
is probably configured as an input or the port or board is unavailable.
Do not pick up - this parameter helps execute the actions specified below
without the call being answered (the call remains in the alerting mode). Thanks
to this, for example, the relay can be activated and the call can be routed by the
PBX at the same time.
Tone - sets the announcement to be played to the calling user whenever a call
comes to this routing object.
Action at pick up - this section defines the action to be executed upon pick up
of a call or upon SMS coming to this routing object.
None - the relay does not respond.
