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.
Information About the EVM-IPVS-16A Network Module
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.
Table 1 Alarm Input and Output Interface Specifications
Specification Range
Alarm Input Sense Voltage Range 12 V to 24 V
Alarm Output Current Load Range 0 mA to 170 mA
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.
