Connecting the Base-station to a controller:
Wiegand:
Connect the following lines: CN7 Pin 4 (DATA0), CN7 Pin 3 (DATA1) and CN5 Pin
1 (GND) to the corresponding terminals on the controller. Ensure that switch SW2-
3 is ON.
Clock & Data:
Connect the following lines: CN7 Pin 4 (Clock), CN7 Pin 3 (Data), CN7 Pin 2 (Card
Present) and CN5 Pin 1 (GND) to the
corres-ponding terminals of the controller.
Ensure that SW2-3 is OFF.
RS232: This feature is only available on the RS232 m
odel. Connect CN7 Pin 5 (RS232 TX)
to the receive pin of the controller. Connect CN7 Pin 6 (RS232 RX) to the transmit
pin of the controller. Connect CN5 Pin 1 (GND) to the signal GND Pin of the
controller.
RS485: This feature is only available on the R
S485 model. Connect the following lines:
CN7 Pin 6 (RS485 A), CN7 Pin 5 (RS485 B) and CN5 Pin 1 (GND) to the
corresponding terminals of the controller. Ensure that each base station has a
unique address by setting switches SW1-1 through SW1-5.
Connecting the Base-station to a triggering device:
This is done when the Base-station is to operate in ‘Triggered’ mode. A vehicle detector
positioned directly in front of the Base-station unit is used to trigger operation.
The vehicle detector can be a loop detector, capacitive detector or any other unit capable of
providing a CONTINUOUS
relay closure whilst a vehicle is present. In the case of a loop detector
this requires that the unit is configured for PERMANENT PRESENCE.
Connect CN7 Pin 1to the N/O relay output of the triggering device, and CN5 Pin 6 to the RELAY
COMMON connection.
Operating multiple Base-Stations in proximity to one another:
When two or more Base-Station units are operated in proximity to one another they may cause
mutual interference if not synchronised. Synchronisation ensures that their transmissions do not
interfere with one another. To synchronise the units, connect the SYNC lines (CN5 Pin 6) and
GND (CN5 Pin 1) on the 6-pin power connectors to the corresponding pins on all units (i.e. Pin 6
to Pin 6, Pin 1 to Pin 1).
