Connecting to the RS-485 Port

Figure 9 — RS-485 Connector.
The DVR can be controlled remotely by an external device or control system, such as a control
keyboard, using RS-485 half-duplex serial communications signals. The RS-485 connector can
also be used to control PTZ (pan, tilt, zoom) cameras. Connect RX-/TX- and RX+/ TX+ of the
control system to the TX-/RX- and TX+/RX+ (respectively) of the DVR. See Chapter 3 —
Configuration and the PTZ camera or remote controller manufacture's manual for configuring the
RS-485 connection.

Connecting to the Network Port

Figure 10 — Network connector.
The DVR can be networked using the 10/100Mb Ethernet connector. Connect a Cat5 cable with an
RJ-45 jack to the DVR connector. The DVR can be networked with a computer for remote
monitoring, searching, configuration and software upgrades. See Chapter 3 — Configuration for
configuring the Ethernet connections.

Connecting to the RS-232C Port

Figure 11 — RS-232C connector.
An RS-232C port is provided to connect an external modem for remote monitoring, configuration
and software upgrades, text input, and to connect a remote control keyboard. Use a modem cable
with a DB-9S (female) connector to connect to the DVR. See Chapter 3 — Configuration for
configuring the modem.
