2. 2 Telemetry Connection

Multiple DVRs and keypads may be connected via RS-422 (PORT A). Up to two PTZ serial communication lines are supported via RS-485/422 (PORT A, PORT 1 & PORT 2).

2. 2. 1 PORT A RS-422

There are two RJ-11 connections for PORT A which can be used to “chain” the DVR with other devices. The primary use of PORT A is to interconnect two or more DVRs and/or keypads (optional).

PORT A can also be used to connect PTZ cameras by using the RJ-11 Terminal Block.

Note

Even though there are two physical connections PORT A is a single port designed to connect multiple devices in a single communication line.

2. 2. 2 PORT B RS-422/RS-485

PORT B is a 5-pin terminal connection. It can be used as either a full-duplex RS-422 port or a half-duplex RS-485 port.

Use this port to connect PTZ cameras, DVRs or keypads (optional).
