The RuggedServer™ RS416 is an industrially hardened serial device server with an integrated,
fully managed, Ethernet switch, designed to operate reliably in electrically harsh and climatically
demanding environments. Featuring a modular design that can support up to 16 serial ports and up
to 4 Ethernet ports, the RS416 is able to interconnect multiple types of intelligent electronic devices
(IEDs) that have 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.
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. Coupled with the ruggedized hardware
design, the RS416 is 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

4 Installation
4.1 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.
Figure 2: RS416 Series Rack mount chassis orientation options – Front and rear mount.

2008 RuggedCom Inc. All rights reserved Rev104
4.1.1 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 Philips 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 high-vibration, 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.

2008 RuggedCom Inc. All rights reserved Rev104
4.6.4 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.
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.

4.7 Ethernet Ports
4.7.1 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. The RJ45 receptacles can also accept and take advantage of
screened (commonly known as “shielded”) cabling. Figure 19 shows the RJ45 port pins
configuration.
NOTE: RuggedCom does not recommend the use of copper cabling of any length for critical realtime 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.

2008 RuggedCom Inc. All rights reserved Rev104
4.7.2 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).
