702-W DIN RAIL MOUNTING
Install the unit on a standard 35mm Din-Rail. Recess the 702-W unit to allow at least 3” of horizontal
clearance for copper cable bend radius.
DIN-Rail Mounting
To mount the unit to the 35mm DIN-Rail, place
the top edge of the bracket on the back of the
unit against the DIN-Rail's top edge at an upward
angle. Then, rotate the unit downward and back
against the DIN-Rail until it snaps into place.
You may need to adjust the angle of the antennas
depending on the amount of clearance available.
To remove the vertically mounted unit from
35mm DIN-Rail, carefully apply downward
pressure on the unit. Then, rotate the unit
upward and away from the 35mm DIN-Rail and
lift up for removal.
19” Universal Rack Mounting
Most N-Tron™ products are designed to be
mounted on industry standard 35mm DIN-Rail.
However, DIN-Rail mounting may not be suitable
for all applications. Our Universal Rack Mount
Kit (P/N: URMK) may be used to mount the 702-
W to standard 19" racks as an option.

APPLYING POWER (702-W Side View)
Unscrew & Remove the DC Voltage Input Plug from the Power Input Header
Install the DC Power Cables into the Plug (observing polarity).
Plug the Voltage Input Plug back into the Power Input Header.
Tightening torque for the terminal block power plug is 0.5 Nm/0.368 Pound Foot.
Verify the Power LED stays ON (GREEN).
Notes:
Only 1 power supply must be connected to power for minimal operation. For redundant power
operation, V
1
and V
2
inputs must be connected to separate DC Voltage sources. This device will
draw current from both sources simultaneously. Use 16-28 gauge wire when connecting to the
power supply.
The LAN port supports Power over Ethernet and can be used redundantly with the power input
mentioned above.
Recommended 24V DC Power Supplies, similar to: N-Tron’s P/N NTPS-24-1.3:
Input AC 115/230V
Output DC 24-28V
Output Current 1.3A @ 24V

Connecting the Unit
For the 10/100 Base-TX port, plug a Category 5E twisted pair cable into the RJ45 connector. Connect the
other end to the far end station. Verify that the LNK/ACT LED is ON once the connection has been
completed. Use a standard Category 5E straight through or crossover cable with a minimum length of one
meter and a maximum length of 100
meters.
N-Tron recommends the use of pre-
manufactured Cat5E cables to ensure the
best performance. If this is not an option
and users must terminate their own ends
on the Cat5E cables; one of the two color
coded standards shown to the right should
be utilized. If a user does not follow one
of these two color code standards then the
performance and maximum cable distance
will be reduced significantly, and may
prevent the unit from establishing a link.
RJ45 CONNECTOR CRIMP SPECIFICATIONS
Please reference the illustration below for your Cat5 cable specifications:
Revision 04062009 Page 15 of 52
N-TRON SWITCH GROUNDING TECHNIQUES
The grounding philosophy of any control system is an integral part of the design. N-Tron switches are
designed to be grounded, but the user has been given the flexibility to float the switch when required. The
best noise immunity and emissions (i.e. CE) are obtained when the N-Tron switch chassis is connected to
earth ground via a drain wire. Some N-Tron switches have metal din-rail brackets that can ground the
switch if the din-rail is grounded. In some cases, N-Tron devices with metal brackets can be supplied with
optional plastic brackets if isolation is required.
Both V- legs of the power input connector are connected
to chassis internally on the PCB. Connecting a drain wire
to earth ground from one of the V- terminal plugs as
shown here will ground the switch and the chassis. The
power leads from the power source should be limited to 3
meters or less in length.
Alternatively, users can run a drain wire & lug from any of the
Din-Rail screws or empty PEM nuts on the enclosure. When
using an unused PEM nut to connect a ground lug via a machine
screw, care should be taken to limit the penetration of the outer
skin by less than 1/4 in. Failure to do so may cause irreversible
damage to the internal components of the switch.
Note: Before applying power to the grounded switch, you must
use a volt meter to verify there is no voltage difference between
the power supply’s negative output terminal and the device
chassis grounding point.
If the use of shielded cables is required, it is generally recommended to only connect the shield at one end to
prevent ground loops and interfere with low level signals (i.e. thermocouples, RTD, etc.). Cat5e cables
manufactured to EIA-568A or 568B specifications are required for use with N-Tron devices.
In the event all Cat5e patch cable distances are small (i.e. All Ethernet devices are located the same local
cabinet and/or referenced to the same earth ground), it is permissible to use fully shielded cables terminated
to chassis ground at both ends in systems void of low level analog signals.
Drain wire with lug connecting switch chassis to known grounding point.

TROUBLESHOOTING
1. Make sure the PWR (Power LED) is ON.
2. Make sure you are supplying sufficient current for the version chosen. Note: The Inrush
current will exceed the steady state current by ~ 2X.
3. Verify that Link LED is ON for the connected port.
4. Verify cabling used between stations.
5. Verify that cabling is Category 5E or greater for 100Mbit operation.

System Information
Base Station SSID: The Name of the 802.11 Service Set (established by the Host Access Point) the device
is connected to:
While operating in Station mode, displays the BSSID of the Access Point where the device has associated.
While operating in Access Point mode, displays the BSSID of the wireless device itself.
AP MAC: displays the MAC address of the Access Point where the device has associated while operating
in Station mode. MAC (Media Access Control) is the unique HW identifier on each 802.11 radio.
Signal Strength: displays the received wireless signal level (client-side) while operating in Station mode.
The represented value coincides with the graphical bar. Use the antenna alignment tool to adjust the device
antenna to improve the link with other wireless devices. The antenna of the wireless client has to be adjusted
to get the maximum signal strength. Signal Strength is measured in dBm (the Decibels referenced to 1
milliwatt). The conversion is defined as dBm=10log10(P/1mW). So, 0dBm would be 1mW and –72dBm
would be .0000006mW. A signal strength of –85dBm or better is recommended for stable links.
Antenna Alignment: This utility allows the user to optimize the antenna direction for maximum link signal.
More information is provided in the Tools sub-section.
TX Rate and RX Rate: displays the current 802.11 data transmission (TX) and data reception (RX) rate
while operating in Station mode. Data rates at 1,2,5.5,11Mbps (802.11b) and 6,9,12,18,24,36,48,54Mbps
(802.11) are possible. Typically, the higher the signal, the higher the data rate, and consequently the higher
the throughput. For maximum throughput (54Mbps), typically a –70dBm or better signal is required.
Frequency: This is the operating frequency and channel of the 802.11 Service Set (hosted by AP) the client
is connected to. Device uses this frequency to transmit and receive data. For 802.11Na operation, the range
of available frequencies are 5.745-5.825Ghz and for 802.11b/g/n operation, 2412-2472 MHz. However, the
specific frequencies that can be used will vary depending on local country regulations.
ACK Timeout: displays the current ACK Timeout value, which is set on the device manually or adjusted
automatically. The ACK Timeout (Acknowledgment Timeout) specifies how long the N-TRON 702-W
device should wait for an acknowledgment from a partner device confirming packet reception before
concluding the packet must have been in error and requires resending. ACK Timeout is a very important
outdoor wireless performance parameter. The ACK timeout is in microseconds. More information is
provided in the Advanced settings section.
Security: This is the current security setting. More information is provided in the Link Setup section.
Uptime: This is the running total of time the device has been running since last power up (hard-reboot) or
software upgrade. The time is expressed in days, hours, minutes and seconds.
Date: indicates the current system date and time, expressed in the form “year-month-day
hours:minutes:seconds”. System date and time can be retrieved from the Internet services using NTP
(Network Time Protocol).
LAN cable: displays the current status of the Ethernet port connection. This can alert
operator/user/technician that the LAN cable is plugged into the device and there is an active Ethernet
connection.
