2.2 Power Supply Wiring and Grounding
2.2.1 AC Power Supply Wiring and Grounding
Figure 4 - RS910W Power Supply Inputs
The RS910W AC power supply inputs should be connected as follows:
1. +/L should be connected to AC Line/Hot.
2. -/N should be connected to AC Neutral.
3. Surge Ground should be connected to the Chassis Ground via a braided cable or other
appropriate grounding wire. Surge Ground is used as the ground conductor for all surge
and transient suppression circuitry internal to the unit.
4. Chassis Ground must be connected to the AC ground terminal.
NOTES:
1. Equipment must be installed according to the applicable country wiring codes.
2. All line-to-ground transient energy is shunted to the Surge Ground terminal. In cases
where users require the inputs to be isolated from ground, remove the ground braid
between Surge and Chassis Ground. Note that all line-to-ground transient protection
circuitry will be disabled.

3.1.4 RS485 Wiring
Each RS485 port can communicate to multiple RS485 devices by daisy chaining devices over a
single twisted pair with transmit and receive signals on the same two wires (half duplex). The
following guidelines should be followed to ensure reliable continuous communication:
1. To minimize the effects of ambient electrical noise, shielded cabling is recommended
2. The correct polarity must be observed throughout a single daisy chain
3. The number of devices wired should not exceed 32, and total distance should be less than
4000 feet (at 100Kbps)
4. The COM terminals should be connected to the common wire inside the shield.
5. The shield should be connected to earth ground at ONE single point to avoid loop currents.
6. The twisted pair should be terminated at each end of the chain.
Figure 12 shows the recommended RS485 wiring.

3.1.5 Serial Port Transient Protection
RuggedCom does not recommend the use of copper cabling of any length for critical real-time
substation automation applications. However, transient suppression circuitry is present on all
copper ports to protect against damage from electrical transients and to ensure IEC 61850-3 and
IEEE 1613 Class 1 conformance. This means that during the transient event communications
errors or interruptions may occur but recovery is automatic. RuggedCom also does not recommend
to use these ports to interface to field devices across distances which could produce high levels of
ground potential rise, (i.e. greater than 2500V) during line to ground fault conditions.

4 Ethernet Ports
4.1 RJ45 Ethernet Ports
The RS910W has several 10/100Base-TX ports that allow connection to standard category 5
(CAT-5) unshielded twisted-pair (UTP) cable with RJ45 male connectors. The RJ45 receptacles
are directly connected to the chassis ground on the unit and can accept CAT-5 shielded twisted-
pair (STP) cables. If shielded cables are used, care must be taken to ensure the shielded cables
do not form a ground loop via the shield wire and the RJ45 receptacles at either end. The figure
below shows the RJ45 port pin-out.

4.2 Fiber Optic Ethernet Ports
Depending on the order code of the product, the RS910W can be equipped with several different
fiber optic ports. The Transmit (Tx) and Receive (Rx) connections of each port must be properly
connected and matched for proper link and operation. The drawings in the following figures show
each fiber optical connector style with a side and top view to allow the user to identify the proper
cable connection orientation.

8 Appendix A - RuggedWireless ™ Frequently Asked
Questions (FAQ)
What factors can affect wireless coverage/range?
Range estimates are typical and require line of sight. Basically that means you will need a clear
unobstructed view of the antenna from the remote point in the link. Keep in mind that walls and
obstacles will limit your operating range and could even prevent you from establishing a link.
Signals in the 2.4 Ghz generally will not penetrate metal or concrete walls. Trees and leaves are
also obstructions to 802.11 frequencies so they can partially (or even entirely) block the signal.
Other factors that will reduce range and affect coverage area include metal studs in walls, concrete
fiberboard walls, aluminum siding, foil-backed insulation in the walls or under the siding, pipes and
electrical wiring, furniture and sources of interference. Other sources of interference include the
microwave oven, other wireless equipment, cordless phones, radio transmitters and other electrical
equipment. Due to the increased gain, installing range extender antennas in the presence of
interference could actually yield either no improvement or worse range.
Which WiFi (802.11) Antenna type should I choose? Patch/Directional Antennas
Choose a patch if you want the signal more focused than from an omni-directional antenna . Patch
antennas typically transmit the signal with approximately a 30 degree beam width. This is ideal for
use in office locations, ie placed at one end of room to provide coverage for it's entire length. They
can also be used outdoors to provide short distance point to point links.
When would I choose a Parabolic Grid Antenna?
These antennas have a very narrow beamwidth and are ideal for point-to-point bridge links. Grid
antennas are highly directional and they should only be chosen to aim at one small (i.e.
concentrated) spot.
When would I choose an Omni-Directional Antenna?
Choose an Omni-directional antenna to provide a signal over a full 360 degree radius.
How many clients can associate with an access point?
An Access Point is a shared medium and acts as a wireless hub. The performance of each user
decreases as the number of users increases on an individual AP. Ideally, not more than 24 clients
should associate with the AP because the throughput of the AP is reduced with each client that
associates to the AP.
How do I convert between power expressed in ‘milliwatt’ and power expressed in ‘dBm’
units?
The formula used to convert stated ‘power’ levels to decibels (dBm – milliwatt @ 50 or 600 ohm
impedance) is given as: dBm = 10 * Log (Power in mW / 1 mW)
Conversely, the formula used to convert stated ‘power’ levels to milliwatts when expressed in dBm
is given as: Power (mW) = anti-log (dBm / 10)
