Antennae
IMPORTANT NOTE: The Ranger or Ultraview 1030/1050 wireless antenna and the WNI antenna are
different:
• The Ranger or Ultraview 1030/1050 wireless use the 117-0029-00 Ranger 2.4 GHz Dipole Antenna
(stubby antenna), which has a gain of x2. Do NOT
use this antenna with a 90310 Wireless Network
Interface (WNI)! Do NOT use the WNI antenna (650-0521-00) with a wireless monitor (90309 or
90367 / 90369)!
• The 90310-A/-B/-C WNI uses the 650-0521-00 Base-Mounted WNI Omni-directional Antenna (with
6' cable), which has a gain of x1. Do NOT
use this antenna with 90309 or 90367 / 90369 Wireless
monitors. Do NOT
use the 117-0029-00 antenna with a 90310!
DO NOT
try to use an Ultraview 1030/1050 wireless as a Master to do a site survey! Obviously, if
you set an Ultraview 1030/1050 wireless to be a Master to use in place of the 90310 WNI, you will get
TWICE the received signal level that a real WNI would produce because of the higher antenna gain. If
this is done for a site survey, this will result in designing a layout that will be too cold to work with a real
WNI Master.
WNI / 90486 / antenna wall mounting
The WNI uses the same wall mounts as the 90485 remote module housing.
Power Source
The power for the WNI (Wireless Network Interface) Master unit comes from a 90486 power supply. Each
WNI (90310-A, -B, or -C) should have its own dedicated 90496 external power supply.
Cables
There is no direct connection between a WNI and a central station monitor; they communicate using
ethernet. The cables for communication from the ethernet repeaters use the same 15 pin AUI cables as
existing SMI network cables. The 90310 housing utilizes the same DC power cables as the 90485 Module
Housing.
