The “Optocoupled I/O test” panel
The two outputs, GPO1 and GPO2, (GPO means General Purpose Output) have the purpose to react when a
person is counted:
• GPO1: By default is associated to incoming people
• GPO2: By default is associated to outgoing people
The optocoupled output electronics behave as low-side switches normally closed.
When the PCN-1001 detects a person, one of the two outputs (depending on the direction of the person) turns its
status to open for a period of “GPO-Open-Time” milliseconds.
The GPO-Open-Time (GPOOT) can be configured inserting a value (from 8 to 1020 milliseconds) in the two
GPO1 and GPO2 open time fields on the “Optocoupled I/O test” panels.
If two people walk in the same direction under the PCN-1001, the first signal will be immediately sent to the
appropriate output, the second will be queued for (2 x GPOOT) milliseconds.
In the Wide-Gate configuration the GPO1 used will be the one of the first PCN-1001.
The GPO2 will be the one of the last PCN-1001. In any case, both the GPO-Open-Times have to be set
connecting the first PCN-1001.
GPI1 Test / GPI2 Test
Follow these steps to test the inputs:
1. In the drop-down lists of the “Optocoupled I/O functions” panel select the option “Test” for either GPI1 or
GPI2
2. Press the “Set” button
3. Press either “GPI1 Test” or “GPI2 Test” button. If a rising edge is received on GPI1 or GPI2, the
corresponding grey rectangle will turn to white. If a falling edge is received it will turn to grey
NOTE:
The “Test” functions are only available via Socket API, not via RS485.
GPO1 Test / GPO2 Test
In order to test the outputs press the “GPO1 Test” or “GPO2 Test” button. The GPOOT value will be set to the
nearest multiple of four lower than or equal to the inserted value.
NOTE:
The “Test” functions are only available via Socket API, not via RS485.
