SUBJECT: 9160 Wireless Gateway Installation Guide
ORIGINATOR: Gabrielle Neff

DISTRIBUTION: TA and FCN Distribution List
IMPORTANT: The 9160 must be installed by qualified Psion Teklogix personnel.
Choosing The Right Location
Typically, Psion Teklogix conducts a site survey in the plant and then recommends the preferred locations
for the 9160s. These locations provide good radio coverage, minimize the distance to the host computer or
network controller, and meet the environmental requirements.
Environment
The 9160 Wireless Gateway should be located in a well-ventilated area and should be protected from
extreme temperature fluctuations (i.e. direct heater output, shipping doors or direct sunlight). If a
protective cover is required, it must have enough ventilation to maintain the 9160’s surface at or near
room temperature.
Refer to “Chapter 25: Specifications” in the 9160 Wireless Gateway User Manual for a more detailed
description of environmental requirements. Keep in mind that the long term stability of this equipment
will be enhanced if the environmental conditions are less severe than those listed in this manual.
The 9160 should be situated away from the path of vehicles and free from water or dust spray. The 9160
should only be mounted in the upright position, as shown in Figure 1 below. This orientation minimizes
the risk of water entering the 9160, should the unit accidentally be sprayed.
The 9160 is attached to a vertical surface using four fasteners on the rear plate (type of fasteners are
dependent on mounting surface). The top two holes in the rear plate are slots, allowing the unit to be hung
in position before the remaining bolts are installed. The bolts used for installation are SAE 1/4-20.

Maintenance
The 9160 has no internal option switches and does not require physical access; all configuration settings
are done remotely (see “Navigating to Basic Settings” in the 9160 Wireless Gateway User Manual).
Environmental and radio communication considerations do still apply.
Radios
Mini-PCI 802.11g radio without integrated antenna (standard).
Mini-PCI 802.11a/g radio without integrated antenna (optional second radio).
Power And Antenna Cables
Power
To prevent accidental disconnection and stress on the 9160, antenna and power cables should be secured
within 30 cm of the unit. Secure the cables with ties to the cable tie mounts on the 9160 (see Figure 1
above). A single phase power outlet (range 100 to 240 VAC rated 1.0A minimum) should be installed
within one metre (3.1 feet) of the 9160. The 9160 automatically adjusts to input within that power range.
The power cable is removable and is available in the power type specific to your location. The 9160 AC
power supply has a universal input via a standard IEC320 connector.
To eliminate the need for AC wiring, the 9160 Wireless Gateway is compliant with IEEE 802.3af and can
be powered over its Ethernet connection. For detailed information, see “Power Over Ethernet
Requirements” in the 9160 Wireless Gateway User Manual.
WARNING: To avoid electric shock, the power cord protective grounding conductor must always be
connected to ground.
Antennas
The type of antenna required for each installation depends on the coverage requirements and the
frequencies used. For more detailed information on the Psion Teklogix antennas available for use, please
refer to TA071. Generally, a site survey determines the appropriate antenna.
The 9160 has four reverse-thread SMA jacks on top. The two front connectors can connect to RA2060
(802.11g), and the two rear SMAs can connect to RA2050 (a/g). See Figure 2.

The RA2050 and RA2060 radios support transmit and receive antenna diversity. With transmit diversity
the radio decides if it wants to transmit on the main or diversity antenna port. Transmit diversity switching
is much slower than diversity switching, typical dwell time is in the order of seconds. Diversity switching
is done on each packet received.
Normally the same antenna is used for both the main and diversity port. There is a special case where
different antennas are used, such as setting up a WDS link in Europe where the EIRP puts a limit on the
gain of the main antenna. Please refer to TA# 065 for more information.
A dual band ‘screw-on’ articulated blade antenna is available for small areas. A maximum of two screwon antennas is allowed, and they can be used with either Radio 1 or Radio 2. In other words, you can
install the screw-on antennas on SMA jacks 1 and 3 (for Radio 1), or 2 and 4 (for Radio 2) ONLY. Never
install them in any other combination, doing so will cause interference between the radios (even if one
operates in the 2.4 GHz and the other in the 5 GHz band.)
WARNING: Never operate the 9160 without a suitable antenna or a dummy load.
IMPORTANT!
1. FCC Requirement
To meet FCC regulatory approval, the max RF power in the 9160 must be set according to the
type of antenna used. As professional installers, Psion Teklogix personnel must abide by this rule
or risk legal action brought against the company.
To set the maximum RF output from the radio follow these steps:
• telnet to the 9160.
• Enter “max_tx wlan0 xx” to set maximum transmit power to xx% of Radio 1’s default
value. Similarly, “max_tx wlan1 xx” sets the maximum transmit power for Radio 2 (a/g).
Example: if max_tx is set to 60% and "Transmit power" on the web UI is set to 50%, the
total power transmitted is 30%, (0.6 x 0.5 = 0.3). See Table 1 for values.
Tip: determine the radio type (RA2050 or RA2060), then determine if operating in a
country that follows FC or ET regulations, and finally, read the % value for the antenna
in use.
