Product Overview
1 Product Overview
1.1 Functional Overview
RuggedServer™ RS416 represents a family of industrially hardened serial device
servers with integrated, fully managed, Ethernet switches. The RS416 is designed to
operate reliably in electrically harsh and climatically demanding environments. Featuring
a modular design that can support up to 16 serial ports, up to 4 Ethernet ports, and
optional IRIG-B support, the RS416 is able to interconnect multiple types of intelligent
electronic devices (IEDs) that require different methods of communications. Using the
RS416 results in fewer connectivity devices (which reduces overall system costs) and
also extends the useful life of existing legacy IEDs (which minimizes capital expenditure
for new equipment).
The RS416 provides a high level of immunity to electromagnetic interference and heavy
electrical surges typical of environments found in electric utility substations, factory floors
or in curb side traffic control cabinets. The RS416 meets or exceeds a wide range of
industry standards including IEC 61850, IEEE 1613, IEC 61000-6-2, IEC 61800-3, and
NEMA TS-2. The RS416 also features a wide operating temperature range of -40°C to
+85°C allowing it to be installed in virtually any location.
For applications requiring high availability, the RS416 provides the option for integrated
dual redundant power supplies, each capable of accommodating a wide range of input
voltages for worldwide operability. Also unique is the ability to have each power supply
fed from different voltage levels and/or sources thereby providing great flexibility in
creating high availability systems. The RS416P provides IEEE 802.3af standard Power
over Ethernet (PoE) on its 10/100BaseTx ports.
The embedded Rugged Operating System (ROS®) within the RS416 provides advanced
layer 2 and layer 3 networking functions, advanced cyber security features, and a full
array of intelligent functionality for high network availability and manageability. These
features, in addition to the ruggedized hardware design, make the RS416 ideal for
creating mission-critical, real-time, control applications in any harsh environment. The
RS416 is also backed by RuggedCom's all inclusive five year warranty and unsurpassed
technical support.
The RS416 implements both the Precision Time Protocol (PTP - IEEE 1588 v2) and
IRIG-B for high-precision time synchronization across both Ethernet and legacy
networks.

2.1 Mounting
The RS416 has been designed with maximum mounting and display flexibility.
Customers can order an RS416 that can be mounted in a standard 19” rack, 1” DIN Rail,
or directly onto a panel. For rack mount installations, the RS416 can be ordered with
connectors on the front of the unit, or located on the rear of the chassis to allow for all
data and power cabling to be installed and connected at the rear of the rack. See Figure
2 for rack mount orientation examples.

2.1.1 Rack Mounting
The RS416 can be rack mounted using the included rack mount adapter assemblies
shown in Figure 3. Secure the one rack mount adapter to the front of each side of the
chassis using the included black PAN head Phillips screws in the positions shown in
Figure 4. The entire chassis can then be mounted to a standard 19” rack. An additional
two rack mount adapters are included to optionally secure the rear of the chassis in highvibration, or seismically active locations.
Figure 3: 19” Rack Mount Adapters
Figure 4: Rack mount adapter mounting location
NOTE: Since heat within the RS416 is channeled to the enclosure, it is recommended that 1 rack
unit of space (1.75”) be kept unpopulated and free of equipment above each RS416 product to
allow for a small amount of convectional airflow. Although forced airflow is not necessary, any
increase in airflow will result in a reduction of ambient temperature that will improve long-term
reliability of all equipment mounted within the rack space.

Serial Ports
3.6 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.

Serial Ports
3.7 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 using 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.

IEEE 1588 is designed to fill a niche not well served by either NTP or IRIG-B. IEEE1588
is designed for local systems requiring accuracies on the order of 100 nanoseconds.
IEEE 1588 is also designed for applications that cannot bear the cost of a GPS receiver
at each node or for which GPS signals are inaccessible. Every Ethernet port on the
RS416 supports IEEE1588.
4.1 IRIG-B Ports
The IRIG-B output ports described in sections 3.3 and 3.5 derive their time from the
IRIG-B module, which occupies one slot in lieu of a two-port Ethernet module. The IRIGB module has one dedicated input and one dedicated output. These ports operate in
IRIG-B PWM mode (IRIG-B006 or IRIG-B007) only.

4.2 IRIG-B Connection Considerations
The number of IRIG-B devices that can be connected to a given IRIG-B output is
dependent on the cabling type and length as well as the input impedances of connected
devices. Figure 25 shows a simplified circuit diagram of the interface between an IRIG-B
output and connected devices.
SourceCablingDevice

Vs
Figure 25: IRIG-B Output Simplified Schematic
RL/N
The maximum number of devices (N) that can be connected to the source is determined
by verifying that the source current (IS) required to drive the connected devices is less
than the maximum drive current the output can provide, and that the load voltage (VL)
seen by the connected devices is greater than their minimum required voltage. Refer to
section 6.3.2 for IRIG-B port specifications.
5 Ethernet Ports
5.1 Copper Ports
The RS416 may have up to 4 10/100BaseTX ports that allow connection to standard
CAT-5 UTP cable with RJ45 male connectors. All RJ45 Ethernet ports feature auto-

negotiating, auto-polarity, and auto-crossover functions. On the RS416P, these ports
support PoE, providing up to 15.4W per port at a nominal 48VDC, auto-sensing and
auto-power off when cables are disconnected. The RJ45 receptacles can also accept
and take advantage of screened (commonly known as “shielded”) cabling. Figure 26
shows the RJ45 port pins configuration.
NOTE: 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.

5.2 Fiber Optic Ports
Depending on the order code of the product, the RS416 can be equipped with several
different types of fiber optic ports. The Transmit (TX) and Receive (RX) connections of
each port must be properly connected and matched for proper link and operation.
Modules populated on the top row of the device typically have locking mechanisms or
tabs towards the top of the unit. Modules located on the bottom row of the device have
locking mechanisms or tabs towards the bottom of the device.
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.If
modules are populated on the bottom row of the device, the transceiver orientation will
be reversed (i.e. RX and TX will be reversed).
