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.
Figure 4-1 Cisco Input Module
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 Cisco Input Module includes the following:
•20 resistors (1K) for input supervision
•2 mounting brackets, with 4 screws for each bracket
•Regulatory compliance and safety information
•Quick start guide
•Connector plugs:

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 the "Power Options and Requirements" section on page 1-12 for more information.
•Verify that you have the necessary mounting brackets or other hardware. See the "Mounting a Gateway or Optional Module" section on page 1-14.
Procedure
To install the module, complete the following procedure:
Step 1 Mount the module to a wall. See the "Mounting a Gateway or Optional Module" section on page 1-14 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 the "Power Options and Requirements" section on page 1-12 for more information.

DC power GND (ground) Connects the DC ground wire to the module. |

|
DC power Voltage In (VIN) Connects the DC Voltage In (VIN) wire to the module. |
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 the "Optional Expansion Modules" section on page 1-5 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 Cisco Physical Access Manager User Guide for information to configure the module ports.
