Installation
This section describes how to install the TVN 21 unit.
Installation environment
When installing your product, consider these factors:
• Ventilation
• Temperature
• Moisture
• Chassis load
Ventilation: Do not block any ventilation openings. Install in accordance with the
manufacturer’s instructions. Ensure that the location planned for the installation of the
unit is well ventilated.
Temperature: Consider the unit’s operating temperature (-10 to +55 ºC, 14 to 131 °F)
and noncondensing humidity specifications (10 to 90%) before choosing an installation
location. Extremes of heat or cold beyond the specified operating temperature limits
may reduce the life expectancy of the NVR. Do not install the unit on top of other hot
equipment. Leave 44 mm (1.75 in.) of space between rack-mounted NVR units.
Moisture: Do not use the unit near water. Moisture can damage the internal
components. To reduce the risk of fire or electric shock, do not expose this unit to rain
or moisture.
Chassis: Equipment weighing less than 15.9 kg (35 lb.) may be placed on top of the
unit.
Unpacking the TVN 21 and its accessories
When you receive the product, check the package and contents for damage, and verify
that all items are included. There is an item list included in the package. If any of the
items are damaged or missing, please contact your local supplier.
Items shipped with the product include:

SATA HDD, CD/DVD-RM.
6. Connect to a power cord.
7. Connect to speakers for audio output.
8. Connect to a VGA monitor.
9. Connect to an HDTV. The HDMI connection

13. Connect to a keyboard (KTD-405 shown).
14. Connect up to 16 alarm input cables to relay

15. Connect up to four alarm relay outputs.
Wiring the keypad
The keypad uses RS-485 simplex wiring. The signal is transferred by a single twisted
pair line. A shielded STP CAT5 network cable is recommended. Ground one end of the
cable, either the first or last device on the RS-485 line.
The maximum number of devices that can be installed in one bus is 255, with a
maximum cable length of 1200 m. The cable length can be expanded using a signal
distributor.
Both the first and the last device in series should be terminated with 120 Ohm
resistance to minimize line reflections. See Figure 2 below.

Use an RS-485 signal distributor to increase the maximum number of devices on the
bus as well as the total range. Each distributor output provides another RS-485 bus,
extending the output an additional 1200 m. Up to 31 NVRs can be connected to each
output. See Figure 4 below.

several keypads.
See section “RS-485 por ts ” below to configure the RS-485 port communication settings.

The NVR is supplied with an infra red (IR) remote control unit. Like the mouse, it can be
used to operate all of the main functions o f th e TVN 21.
The IR remote control can be programmed with a unique device ID address so that the

programming is necessary if using a single TVN 21.
The device ID address only applies when using a remote control and not when using a
keypad.
