The Cisco Physical Access Gateway
A Cisco Physical Access Gateway is installed near each door to provide processing and control for the
connected door hardware, such as card readers, locks, and other input and output devices. This
architecture allows access control to be deployed incrementally, door by door, eliminating the central
panel and simplifying system design, wiring, and planning.
The Gateway is required, and can control up to two doors. Each Gateway supports the following:
If additional connections are required, you can connect up to 15 optional modules using a three-wire
Controller Area Network (CAN) bus. These modules can be added or removed without affecting the
operation of the system or other modules. See the “Optional Expansion Modules” section on page 1-5
for more descriptions of the available modules.
Note The modules are connected using the CAN1 interface. The CAN2 interface is not supported in this
release.
