Video Ports

16 video ports are provided, video ports 0 and 1 can be configured for input or output. The remaining 14 video ports can be configured for input only.

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.
