Figure 5 - DC Power supply wiring and grounding diagram

The 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 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.

3 Ethernet Ports

3.1 RJ11 Ethernet over VDSL Port

3.1.1 Overview

The Ethernet over VDSL (EoVDSL) port operates in pairs with one unit configured as the Master
and the other as the Slave. In VDSL literature the terms Central Office (CO) or Line Termination
(LT) are used interchangeably for the Master and the terms Customer Premise Equipment (CPE)
or Network Termination (NT) are used interchangeably for the Slave. The Master unit dictates the
line configuration settings to the Slave so all EoVDSL configuration is done on the Master. Data
flowing from the Master to the Slave is designated “downstream” while data flowing from the Slave
to the Master is designated “upstream”.

RuggedCom offers two flavours of VDSL: Universal EoVDSL and Long-Reach EoVDSL. Universal
EoVDSL ports are Master/Slave selectable and offer symmetric data rates up to 35 Mbps with
distances up to 2.5 km. Long-Reach EoVDSL ports are fixed as either Master or Slave but offer
asymmetric data rates up to 40 Mbps with distances up to 5 km. The Universal and Long-Reach
EoVDSL ports are physically indistinguishable from each other; however, you can determine which
port you have either from the order code or through the software.

3.1.2 Wiring

VDSL typically operates over 2-wire Category 3 (CAT-3) unshielded twisted-pair (UTP) wiring;
however, other categorized or uncategorized twisted-pair wiring will work although the performance
will vary depending on the distance and cable characteristics. It is important that the wiring used
does not have any open leads (also known as bridged taps or drop-lines) along its length because
this will impact performance by degrading the signal.

RS900 Family Installation Guide

3.1.3 RJ11 Port

EoVDSL data ports allow connection using RJ11 male connectors. The figure below shows the
RJ11 port pin-out and LEDs. On units with Universal EoVDSL ports the Master LED can be toggled
on or off depending on whether the port is set as a Master or Slave. On units with Long-Reach
EoVDSL ports the Master unit will have the LED permanently on while the Slave unit will have the
LED permanently off.

3.1.4 Configuration & Setup

If the units have Universal EoVDSL ports, use the software to configure one unit as a Master and
the other as a Slave. If the units have a Long-Reach EoVDSL port, no Master/Slave software
configuration is necessary since the ports will already be fixed as Master or Slave. Once configured
as Master and Slave and connected together, the units will then attempt to achieve the maximum
speed based on the line length and conditions. The unit’s link LED may flash on and off several
times before settling on a final link speed and declaring the port up. For detailed configuration
options please consult the Rugged Operating System (ROS) Software User Guide.

RS900 Family Installation Guide

3.1.5 Performance

The EoVDSL ports can be configured in two modes – Auto Mode and Manual Mode. In Auto Mode,
which is the default mode, the unit will step through the different speeds and automatically select
the best bit-rate based on current line conditions. In Manual Mode the user can select one of the
speed settings and the unit will only attempt to attain the set speed. If the line conditions degrade
(reducing the SNR) but the unit is able to maintain the link, an alarm will be triggered to notify the
user of the reduced SNR. If the line conditions degrade such that the unit is unable to maintain the
current link, the unit will restart the scan process if in Auto Mode or re-attempt to attain the set
speed if in Manual Mode.

On 24 American Wire Gauge (AWG) Polyethylene Insulated Cable (PIC) twisted-pair the following

NOTES:

1. The EoVDSL ports are designed to be used on private communications lines for point-to-point
connections and are not to be connected to the Public Switched Telephone Network (PSTN).

2. To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.

3. In Manual Mode, assuming the distance can support the speed setting; the time to port up is
typically 15-30 seconds.

3.2 RJ45 Ethernet Port

Units with 10/100Base-TX ports 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 shows
the RJ45 port pin-out and LEDs.

2. Pins 1, 4, and 6 are connected internally. Pins 7 and 8 are connected internally. The pins are
permanently asserted to 5V so that DTE devices that require DCD, DTR, or CTS signals will
operate. However, hardware flow control via RTS is not recognized.

3. The Common terminals are optically isolated; however, there is transient voltage protection
circuitry between the Common terminals and chassis ground.

4.3 Fiber Serial Port

The 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.

4.4 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 100 kbps).

4. The Common terminals should be connected to the common wire inside the shield.

5. The shield should be connected to earth ground at a single point to avoid loop currents

6. The twisted pair should be terminated at each end of the chain.

The figure below shows the recommended RS485 wiring.

5 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 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.
