5. INSTALLATION
5.1 VHF Antenna
There are two VHF antennas to be connected.
It’s very important to choose a proper location for VHF antenna as a metal object close to the antenna could affect
receiving sensitivity.
The following instructions are helpful:
- The antenna should be kept at least 0.5m from a vertical metal object to avoid RF reflection.
- The antenna should be kept at least 3m from other high power radiator, such as radar antenna.
- Two VHF antennas should not be installed at the same height. One VHF antenna can be installed either under or
above another VHF antenna. The distance between should be more than 2.8m. If two antennas have to be installed
at the same height, the distance between should be more than 10m.
For the cabling, please refer to below suggestions:
- The shorter the cable, the less the loss. The low-loss cable is recommended if the cable is longer than 10m.
- Watertight treatment is required for outdoor connecting.
- The RF cable should be kept at least 10cm from the power cable. The cable cross should be avoided.
5.2 Transceiver
Four screws are supplied to mount the transceiver. The transceiver can be installed either on table or on wall.
Care must be taken when mounting the transceiver to ensure that there is sufficient space for cables and connectors.
Especially, sharp bending of the RF cable must be avoided.
5.3 CONNECTION
5.3.1 POWER SUPPLY
The power cable with a rated capacity of 10A should be used. Suggest using NSR PS-10 Power Supply Unit (DC
24V output).
5.3.2 GNSS DATA INPUT
The input data format should be NMEA0183/4800bps, as IEC61162-1 standard. Refer to the installation drawings.
5.3.3 CONNECT TO PRINTER
As an optional device, NSR NPT-100 is recommended as the printer used for NVR-3000.
