Pole or gantry mounting:
1. When mounting on a pole, refer to the dimensions and recommended minimum size on the goose
neck mounting plate drawing in Appendix B.
2. A hole in the centre of the flange with a diameter of 30 mm will allow for hidden cable access.
3. Ensure that the unit faces the window area of the vehicles to be monitored.
4. Mounting instructions are the same as for the above.
5.1.4. Wiring
Refer to Section 6.1 for connector Pin assignment and to Appendix A for additional information.
Refer to section 5.3.1 for switch locations and settings.
5.1.4.1 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.
RS-232: This feature is only available on the RS-232 model. Connect CN7 Pin 5 (RS-
232 TX) to the receive pin of the controller. Connect CN7 Pin 6 (RS-232 RX) to
the transmit pin of the controller. Connect CN5 Pin 1 (GND) to the signal GND
Pin of the controller.
RS-485: This feature is only available on the RS-485 model. Connect the following
lines: CN7 Pin 6 (RS-485 A), CN7 Pin 5 (RS-485 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.
5.1.4.2 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 Pin1 to the N/O relay output of the triggering device, and CN5 Pin 1 of the screw
terminal block to the RELAY COMMON connection of the triggering device.
5.1.4.3 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 (ie. Pin 6 to Pin 6, Pin 1 to Pin 1).
(Refer to section 6.1)
In addition to the SYNC function, the Base Station also has Base Station ID switch settings. When
several units are operating on the same site, setting different ID’s for each unit ensures that they only
receive codes from the Tags that they themselves have actuated. That is, Base Station ‘A’ will not
receive the code from a Tag actuated by Base Station ‘B’. See Section 4.3.1 for more information.
