Power

Two-pin connector for Voltage In (VIN) and Ground (GND) to connect a 12 to 24 VDC external power source.

CAN interfaces

A 3-wire CAN bus is used to connect additional modules.

Note Modules are connected using the CAN1 interface. The CAN2 interface is not supported in this release.

CAN terminator

The CAN terminator switch is set to ON for the last device in a CAN wiring bus. This switch is set to set to OFF for all other devices in the CAN bus.

Serial Interface

The RS-485 interface is not supported in this release.

Wiegand Interface

One 10-pin Wiegand/clock and data reader interface. This interface can be configured as two 5-pin Wiegand/clock and data interfaces for installations where a 5-pin interface is sufficient.

Note Disconnect power from the Gateway or Reader module before connecting reader devices to the modules. Connecting a reader device when the modules are powered can cause the Gateway or Reader module to malfunction.
