Information About the EVM-IPVS-16A Network Module

The EVM-IPVS-16A network module enables Cisco integrated services routers to capture analog video

signals. The EVM-IPVS-16A network module supports up to 16 simultaneous composite video inputs,

such as video surveillance cameras. The EVM-IPVS-16A network module also provides alarm input

detection, control relay outputs, and RS-485 serial communication interfaces. Figure 1 shows the

EVM-IPVS-16A network module faceplate.

Note You need a router that supports the EVM-IPVS-16A network module. For a list of supported platforms,

see the Cisco Analog Video Gateway Network Module (EVM-IPVS-16A) Data Sheet.

RS-485 Serial Communication Interfaces

The EVM-IPVS-16A network module supports a half-duplex, two-wire RS-485 communication

network, which sometimes is called a ring. The EIA/TIA RS-485 communications standard supports up

to 32 devices (driver/receiver pairs) on a cable of up to 4,000 feet. The EVM-IPVS-16A network module

has two RS-485 ports, supporting up to 64 devices. The EVM-IPVS-16A network module typically acts

as the master for each of the two RS-485 networks.

The RS-485 ports can be used to control camera pan, tilt, and zoom (PTZ) functions, as well as other

RS-485 devices. Because PTZ camera types use different protocols, the EVM-IPVS-16A network

module only supports pass-through mode. In pass-through mode PTZ commands and other data will not

be interpreted.

Alarm Inputs and Control Relay Outputs

The EVM-IPVS-16A network module supports eight contact closure interfaces. Interfaces A0, A1, A2,

and A3 can be configured as alarm input or relay output, the other interfaces are input only. They are

used to detect contact trigger events and control external devices.

In most cases, the contact closure interfaces will be connected to a patch panel through the two terminal

block ports on the network module. The patch panel can provide the bias to the circuit.

Caution The alarm signal input and output (I/O) connections on this unit are intended only for connection to

NEC/CEC Class 2 or equivalent circuit. This means that the voltages applied to alarm signal I/O

connections should not exceed 42.4 Vpk or 60 Vdc and it should be a limited/fused power source. For

more details on Class 2 circuits, refer to the National Electrical Code/Canadian Electrical Code.

Gigabit Ethernet Port

The external Gigabit Ethernet port is disabled by default. If you enable the Gigabit Ethernet interface, it

can act as a routable interface in your network.

Note The EVM-IPVS-16A network module can only be installed in slots that support extension modules. For

information about which slots support extension modules, see Table 1-1 on page 5

Wiring the Terminal Block Connectors

Wire the provided terminal block connectors using the pinout information provided in Table 4. (See

Figure 4.)

Note The wires used to connect to the terminal block are required to be between 26 AWG and 18 AWG.

Figure 4 Wiring the Terminal Block Connectors

Table 4 lists each pin on the terminal block, and the corresponding port information.

Tip When you wire the terminal block connector, label each wire with the pin number, so you can easily

connect the wires to the alarm or RS-485 devices in your network.

Note In Table 4 a plus (+) sign and minus (–) sign are used to note the polarity for the contact closure and

RS-485 ports. For contact closure ports, pins noted with a plus sign must be connected to positive

potential; pins noted with a minus sign must be connected to negative potential. For RS-485 ports, pins

noted with a plus sign must be connected to an RS-485 device non-inverting terminal; pins noted with a

minus sign must be connected to an RS-485 device inverting terminal.

This section describes how to connect the EVM-IPVS-16A network module to devices in the video

surveillance network.

Note If an installation technician has already connected the EVM-IPVS-16A to the devices in your network,

then do not perform this task. Instead, proceed directly to the software configuration for your

EVM-IPVS-16A network module. See the Cisco Analog Video Gateway 1.0 Installation and Upgrade

Guide at:

http://www.cisco.com/en/US/docs/video/cavg/cavginstall/cavginstall.html

Prerequisites

•Install the EVM-IPVS-16A network module in the router chassis. See the Installing Cisco Network

Modules in Cisco Access Routers guide at:

http://www.cisco.com/en/US/docs/routers/access/interfaces/nm/hardware/installation/guide/InstNe

tM.html

•Wire the provided terminal block connectors. See the “Wiring the Terminal Block Connectors”

section on page 6.

Steps

To connect the EVM-IPVS-16A network module to the network, follow these steps:

Step 1 Take the DB-37 end of the provided DB-37 to BNC video breakout cable, and connect it to the VIDEO

connector on the EVM-IPVS-16A network module.

Step 2 Connect the BNC ends of the video breakout cable to the cameras in your network. The cable ends are

labeled with the corresponding port number (0-15).

Step 3 After you have wired the provided terminal block connectors according to the pinout information

provided in Table 4, connect the terminal block connectors to the terminal block on the EVM-IPVS-16A

network module and tighten the screws using a small slotted screwdriver.

Step 4 Connect the other end of the wired terminal block connectors to the RS-485 and contact closure devices

in your network. In most cases, the wires will be connected to a patch panel.

Step 5 (Optional) To connect the EVM-IPVS-16A network module to an external device, use a straight-through

two-pair Category 5e unshielded twisted-pair (UTP) cable, and connect the RJ-45 Gigabit Ethernet port

on the network module to a switch, hub, repeater, server, or other Gigabit Ethernet network device.

What to Do Next

Proceed to the software configuration for your EVM-IPVS-16A network module. See the Cisco Analog

Video Gateway 1.0 Installation and Upgrade Guide at:

http://www.cisco.com/en/US/docs/video/cavg/cavginstall/cavginstall.html

Performing Online Insertion and Removal of the EVM-IPVS-16A Network

Module

The online insertion and removal (OIR) feature enables some Cisco modular access routers to support

the replacement of network modules without switching off the router or affecting the operation of other

interfaces. Also, routing information is maintained during OIR of network modules.

Note If your router does not support OIR, do not perform this task to replace your EVM-IPVS-16A network

module. Instead, see the Installing Cisco Network Modules in Cisco Access Routers guide at:

http://www.cisco.com/en/US/docs/routers/access/interfaces/nm/hardware/installation/guide/InstNetM.

html

Restrictions

•Only the Cisco 3845 router supports OIR of the EVM-IPVS-16A network module.

•All connections made through the EVM-IPVS-16A network module are reset during OIR.

•You must perform OIR with similar modules. If you remove a network module, install another

network module exactly like it in its place.

Steps

To perform OIR of the EVM-IPVS-16A network module in your router, follow these steps:

Step 1 Initiate a console session with your router.

Step 2 Enter configuration mode and shut down the interface:

Router> enable

Router# configure terminal

Router(config)# interface video-Service-Engine slot/0

Router(config-if)# shut

Router(config-if)# shutdown

Router(config-if)# exit
