The “I/O Settings” tab
The PCN-1001 can be interfaced and triggered by means of 2 independent optocoupled inputs and 2
independent optocoupled outputs.
The RS485 port is the main communications interface used when the PCN-1001 is installed on-board a
transportation vehicle.
Each modification to these settings will be automatically saved in the internal flash memory of the PCN-1001 and
takes immediate effect (a reset is not needed).
The “Optocoupled I/O functions” panel
The two inputs, GPI1 and GPI2 (GPI means General Purpose Input), can be used in four different modes.
These can be selected using the two drop-down menus.
Press the “Set” button to confirm the drop-down menu selection
• Do nothing: The system ignores any signals received on the input lines
•
Test: Allows the operator to test the two input lines (See ‘Optocoupled I/O test panel’ on next
page for more details)
• Reset counters: Sets the incoming and outgoing counters to zero when a rising edge is detected. In the
Wide-Gate configuration only the GPI2 can be set as reset. It has to be set connecting the
first PCN-1001 and the signal will be available on the last PCN-1001
• Enable/Disable
counting
When the GPI1 / GPI2 inputs receive a rising edge (they are enabled) the PCN-1001 will
start the counting process.
When the GPI1 / GPI2 inputs receive a falling edge (they are disabled) the PCN-1001 will
stop the counting process.
In the Wide-Gate configuration only the GPI1 can be set as Enable/Disable.
The default mode for the PCN-1001 when powered-up is “Counting Enabled”.
The counting will be Disabled / Enabled only when the GPI changes state.
Example 1:
a) The PCN-1001 is powered up: the counting will be enabled by default
b) The GPI is enabled: the counting was already enabled at power up and nothing change
c) The GPI is disabled: the counting will be disabled
Example 2:
a) The PCN-1001 is powered up: the counting will be enabled by default
b) The GPI is disabled: the counting will be disabled
c) The GPI is enabled: the counting will be enabled
