Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Chapter: Connecting a Cisco Input Module
Connecting a Cisco Input Module
Overview
The optional Cisco Input Module (Figure 4-1) is attached to a Cisco Physical Access Gateway or Cisco Reader Module to provide additional connections for up to ten input devices. Each connection can be configured as supervised or unsupervised. A supervised connection is a four- state connection to determine if the connection is (1) short (2) is open (3)normal state or (4) alarm state. An unsupervised input indicates only normal or alarm.

The optional Cisco Input Module is connected to a Cisco Physical Access Gateway or Cisco Reader Module using a CAN connection to provide connections for additional input devices, as, as shown in Figure 4-2.

Each input port includes a status LED that indicates the following information:
Installing the Cisco Input Module
Install a Cisco Input Module is provide additional input connections for a Cisco Reader Module or Gateway
Before You Begin
Verify the following:
•Verify that the module has access to a power source. See Power Options and Requirements, page 1-10 for more information.
•Verify that you have the necessary mounting brackets or other hardware. See Mounting a Gateway or Optional Module, page 1-11.
Installation Procedure
To install the module, perform the following procedure:
Step 1 Mount the module to a wall. See Mounting a Gateway or Optional Module, page 1-11 for more information.
Step 2 Connect the module to the DC power source:
a. Insert a two-pin connector plug into the DC power port (Figure 4-5)
b. Connect the Voltage In (VIN) and ground (GND) wires.
See Power Options and Requirements, page 1-10 for more information.

Step 3 Connect the module to the CAN bus:
a. Insert a three-pin connector plug into the CAN1 port, as shown in Figure 4-6.
b. Connect the CAN wires to the CAN bus, as shown in Figure 4-7
c. Turn the CAN terminator ON if the device is the last device in a CAN wiring bus.
Note The CAN terminator switch in included on the Reader, Input and Output modules only (the Gateway is always the first device in the CAN bus). Set the terminator switch to OFF for all other modules in the CAN bus.
Note The CAN2 interface is not supported in this release.
See Optional Expansion Modules, page 1-6 for more information.

Step 4 Connect input devices to the module:
a. Insert two-pin connector plugs into the input ports.
b. (Optional, for supervised input connections only). Install two End-Of-Line (EOL) 1K termination resistors in each supervised input interface (one terminator in each connector). Figure 4-8 shows the terminator installation for a Normally Closed (NC) and Normally Open (NO) input connection.
Figure 4-8 Input Connections: Cisco Physical Access Gateway and Reader Module
c. Connect the wires from the input devices.
Note Each of the input connections can be configured as supervised or unsupervised. The tamper (TM) and power fail (PF) inputs can be configured as additional unsupervised ports. A supervised input supports four states: normal, alarm, open and short. An unsupervised input indicates only normal or alarm.
Step 5 See the User Guide for Cisco Physical Access Manager for information to configure the module ports.
