Connecting Monitors
You can connect either one monitor (Single monitor configuration) or two monitors (Dual monitor configuration)
to the HDR 1800. In a Dual monitor configuration, the first monitor in the configuration must be connected to
the DVI-D connector on the HDR 1800; the second monitor can be connected to either the VGA or BNC
connectors.
To connect a monitor to the HDR 1800:
Plug the monitor cable into the corresponding video input (DVI-D, VGA, BNC-Composite) on the back of the
HDR 1800.

NOTE:
You can also connect a monitor that uses the HDMI interface to the DVI-D port on the HDR 1800.
You will need an HDMI male to DVI male adapter (
not provided
).
Connecting a CCTV Keyboard
The HDR 1800 supports all CCTV keyboards supported in Nextiva VMS. The HDR 1800 provides two serial
ports for connecting CCTV keyboards:
COM1: RS-232
COM2: RS-422
NOTE:
You can use the RJ45 to DB9 adaptor with some CCTV keyboards that uses an RJ45 connection,
but you need to configure the RJ45 to DB9 adaptor wires (color coded) to the appropriate pins on
the DB9.
To connect a CCTV keyboard:
Use the following wiring scheme to connect the CCTV keyboard’s serial cable to the corresponding serial
(DB9) port on the back of the HDR 1800.
Once the connection is done, you must set the baud rate, parity, and other parameters for the serial port in
Nextiva VMS Control Center; for more information, refer to the Nextiva
HDR 1800 User Guide
.
Powering On the HDR 1800
Once the power and network cables and monitors are connected to the HDR 1800, you can power it on.
To power on the HDR 1800:
1. Make sure the power adaptor for the HDR 1800 is connected to a power outlet (or surge-protection
device).
2. Make sure the monitors connected to the HDR 1800 are powered on.
