Installation Instructions G5
Revision C, September 2019
Figure 15 shows the wiring configuration between a Basestation and the components of a Dual-Lane drive-thru. If the installation is for a
Single-Lane operation, refer to Lane 1 wiring in the illustration above.
Vehicle Detector 1 (D1_12V, D1_GND and D1_DET) must always be used for Lane 1 Basestation operation and Vehicle Detector 2
(D2_12V, D2_GND and D2_DET) must always be used for Lane 2 Basestation.
Figure 15.
K. Auxiliary Detector Relays
You can use the Basestation’s vehicle detection circuits to operate an auxiliary relay for a number of convenient uses (typically an external
greeter or timer module, but could also be used to operate a vehicle approach chime or other device that is independent of the intercom
system). Virtually any device that can be activated by opening or closing a switch can be linked to vehicle detection.
The relay terminals are numbered according to the vehicle detector they are paired with. For example, R_NC, R1_NO, and R1_COM are
paired with Vehicle Detector 1.
There are several other sources from which to obtain the vehicle detector relay signals. They are:
1. The 1_NO and 1_COM from Lane 1 connector and 2_NO and 2_COM from the Lane2 Connector.
2. The 16 logical GPIOs can be configured via the basestation’s System Menu, to pair up with the vehicle detectors for Lane 1 or
Lane 2.
