Chapter: Connecting a Cisco Reader Module
Connecting a Cisco Reader Module
Overview
The optional Cisco Reader Module (Figure 3-1) is similar to the Cisco Physical Access Gateway, providing the same ports for Wiegand readers and other input and output devices. The Cisco Reader Module is attached to a Cisco Physical Access Gateway to provide additional connections for one or two doors, but does not include Ethernet connections for the IP network. Power is supplied using the 2-pin connector for 12 to 24 VDC external power.
Figure 3-1 Cisco Reader Module
The Cisco Reader Module is connected to a required Cisco Physical Access Gateway using a CAN connection, as shown in Figure 3-2.

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 |
|
|
|
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 |
|
|
|
Input interfaces Three input interfaces used to sense the contact closure. Each input can be configured as supervised or unsupervised and can be configured to sense a Normally Open (NO) or Normally Closed (NC) contact. • • |
|
|
|
Output interfaces Three Form C (5A @ 30V) relay output interfaces. Each output can be configured as either Normally Closed (NC) or Normally Open (NO). • • Notes: • • • – – |
|
|
|
PF Power fail input: an unsupervised input that raises a "power fail" alarm when the circuit is open. Can be configured as an additional unsupervised port. An unsupervised input indicates only normal or alarm. The corresponding LED is red when circuit is open (when no input is connected). |
|
|
|
TM Tamper input: an unsupervised input that raises a "tamper" alarm when the circuit is open. Can be configured as an additional unsupervised port. An unsupervised input indicates only normal or alarm. The corresponding LED is red when circuit is open (when no input is connected). |

Status LEDs
Table 3-1 describes the Gateway module status LEDs:
Installing the Cisco Reader Module
Installing the Cisco Reader Module is similar to installing the Gateway, except for the following:
•There are no Ethernet ports. The Cisco Reader Module is not directly connected to the IP network, and is not directly configured.
•The Cisco Reader Module does not support Power over Ethernet (PoE). The device is connected to a DC power source.
•The Cisco Reader Module must be terminated if it is the last device in a CAN wiring bus. See the "CAN Bus Connections for Optional Modules" section for more information.
Before You Begin
Before you install a Cisco Reader Module, verify the following:
•Verify that the module has access to a power source. See the "Power Options and Requirements" section for more information.
•Verify that you have the necessary mounting brackets or other hardware. See the "Mounting a Gateway or Optional Module" section.
Procedure
To install the Cisco Reader Module, perform the following procedure:
Step 1 Mount the module to a wall. See the "Mounting a Gateway or Optional Module" section 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 3-5)
b. Connect the Voltage In (VIN) and ground (GND) wires.
See the "Power Options and Requirements" section 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 Gateway using a CAN bus:
a. Insert a three-pin connector plug into the CAN1 port, as shown in Figure 3-6.
b. Connect the CAN wires to the CAN bus, as shown in Figure 3-7
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 for more information:

Figure 3-7 CAN Bus Wiring
Step 4 Connect one or two door reader devices to the Wiegand interface using one of the following configurations:
•Connect a single door reader using all 10 Wiegand interface pins.
•Connect one or two door readers using 5-pin Wiegand interface connections (for installations where a 5-pin interface is sufficient).
Figure 3-8 shows the location of the Wiegand interface connections. The table describes the connections for 10-pin and 5-pin reader interface connections. The wire connectors from the reader device are shown in parentheses. If attaching a second reader, use the alternative connections shown in the column on the far right.

Step 5 Connect input devices to the module:
a. Insert two-pin connector plugs into the input ports (Figure 3-10).
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 3-9 shows the terminator installation for a Normally Closed (NC) and Normally Open (NO) input connection.
Figure 3-9 Input Connections: Cisco Physical Access Gateway and Reader Module
c. Connect the wires from the input devices (Figure 3-10).
Note Each of the input connections can be configured as supervised or unsupervised. The tamper and power fail 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.
Figure 3-10 Input Connections: Cisco Physical Access Gateway and Reader Module
Step 6 Connect output devices to the module:
a. Insert three-pin connector plugs into the output ports (Figure 3-11).
b. Connect the wires from the output devices.
–Common (C) is always used, and either NC or NO is used to complete the connection.
–If the relay is normally open, use the C & NO connections. The circuit is closed when triggered.
–If the relay is normally closed, use the C & NC connections. The circuit is opened when triggered.
