2.1 Din Rail Mounting

An optional DIN rail mounting bracket is available for the RS910W. The figure below details mounting instructions for the standard 1” DIN Rail.

Figure 3 - RS910W DIN Rail Mounting

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.

2.2.2 DC Power Supply Wiring and Grounding

Figure 5 - DC Power supply wiring and grounding diagram

The RS910W low voltage DC power supply features reverse polarity protection and dual independent inputs. The latter feature allows the connection of two DC sources with the same nominal voltage to provide redundant power supply inputs.

The RS910W DC power supply inputs should be connected as follows:

1. Connect to the DC inputs according to the polarity markings on the unit.

2. 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.

3. Chassis Ground must be connected to the protective earth.

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.

2.2.3 Dielectric Strength Testing

Units which are to have dielectric strength testing (HIPOT testing) done in the field must have the braided ground cable disconnected during the test. This is required in order to prevent the surge suppression circuitry, which is connected to surge ground, from being activated.

Figure 6 - Dielectric Strength Testing

2.3 Failsafe Output Wiring

The Failsafe output relay is provided to signal critical error conditions that may occur on the RS910W. The contacts are energized upon power up of the unit and remain energized until an alarm condition or power loss occurs. The behavior of the failsafe relay is configurable via the RuggedSwitch Operating System. Consult the RuggedSwitch Users Guide for details.

Figure 7 - RS910W Failsafe Output Relay

2.4 RS232 Console Port Wiring

The RS232 port is used for configuring the RS910W. A straight-through serial cable with a DB-9 connector is required. There is no need to crossover the TxD and RxD signals from the PC side since this has been done internally as is shown in the figure below.

Pin Signal

1 Internal Connection 2 Transmit Data 3 Receive Data 4 Internal Connection 5 Ground 6 Internal Connection 7 Internal Connection 8 Internal Connection 9 No Connection

Figure 8 - RS232 Female DCE pin-out

NOTE: This port is not intended to be a permanent connection and the cable length should not

exceed 2m (6.5 feet). Pins 1,4,6 are connected internally, and pins 7, 8 are connected internally.

3 Serial Ports

The RS910W can be equipped with a Fiber Serial Interface, RS232/RS485/RS422 DB9 serial ports or RS232/RS485/RS422 RJ45 serial ports.

3.1.1 Fiber Serial Interface

The RS910W can be equipped with a Fiber Serial Interface (ST connector only) which allows RS485, RS422, or RS232 devices to communicate over secure, noise immune, optically isolated, fiber optic cabling at extended distances as well as protocol independent conversion to multimode fiber optics.

Figure 9: Fiber Serial Interface (ST Connector)

3.1.2 RS232/RS485/RS422 via DB9

Each port is individually selectable via software to be RS232, RS485 or RS422. The DB9 port and pin-out is shown in Figure 10.

NOTE: Pins 1, 2, and 3 are connected internally. Pins 7 and 8 are connected internally. No internal termination is provided.

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.

Figure 12: Conceptual recommended RS485 wiring diagram

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 twistedpair (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.

NOTE: RuggedCom does not recommend the use of CAT-5 (10/100Base-TX communications)

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 recommended 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.

4.2 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)
