This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety
alert symbol, notices referring only to property damage have no safety alert symbol. These notices shown
below are graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger
will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning
relating to property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the

Tools/Materials Purpose
Phillips screwdriver For mounting the device to a panel.
4 x #8-32 screws For mounting the device to a panel.
1.4 Decommissioning and Disposal
Proper decommissioning and disposal of this device is important to prevent malicious
users from obtaining proprietary information and to protect the environment.
Decommissioning
This device may include sensitive, proprietary data. Before taking the device out of
service, either permanently or for maintenance by a third-party, make sure it has
been fully decommissioned.
For more information, refer to the associated Configuration Manual.
Recycling and Disposal
For environmentally friendly recycling and disposal of this device and related
accessories, contact a facility certified to dispose of waste electrical and electronic
equipment. Recycling and disposal must be done in accordance with local
regulations.
1.5 Cabling Recommendations
Before connecting the device, be aware of the recommendations and considerations
outlined in this section.
1.5.1 Protection On Twisted-Pair Data Ports
All copper Ethernet ports on RUGGEDCOM products include transient suppression
circuitry to protect against damage from electrical transients and conform with
IEC 61850-3 and IEEE 1613 Class 1 standards. This means that during a transient
electrical event, communications errors or interruptions may occur, but recovery is
automatic.
Siemens also does not recommend using copper Ethernet ports to interface with
devices in the field across distances that could produce high levels of ground
potential rise (i.e. greater than 2500 V), during line-to-ground fault conditions.

Introduction
1.5.2Gigabit Ethernet 1000Base-TX Cabling Recommendations
1.5.2 Gigabit Ethernet 1000Base-TX Cabling Recommendations
The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbit/s Ethernet
communications over distances of up to 100 m (328 ft) using all 4 pairs in category
5 (or higher) balanced, unshielded twisted-pair cabling. For wiring guidelines,
system designers and integrators should refer to the Telecommunications Industry
Association (TIA) TIA/EIA-568-A wiring standard that characterizes minimum cabling
performance specifications required for proper Gigabit Ethernet operation. For
reliable, error-free data communication, new and pre-existing communication paths
should be verified for TIA/EIA-568-A compliance.
The following table summarizes the relevant cabling standards:
Cabling
Category
1000Base-
TX Compliant
Required Action
< 5 No New wiring infrastructure required.
5 Yes Verify TIA/EIA-568-A compliance.
5e Yes No action required. New installations should be designed with
Category 5e or higher.
6 Yes No action required.
> 6 Yes Connector and wiring standards to be determined.
Follow these recommendations for copper data cabling in high electrical noise
environments:
• Data cable lengths should be as short as possible, preferably 3 m (10
ft) in length. Copper data cables should not be used for inter-building
communications.
• Power and data cables should not be run in parallel for long distances, and
should be installed in separate conduits. Power and data cables should intersect
at 90° angles when necessary to reduce inductive coupling.
• Shielded/screened cabling can be used when required. Care should be taken to
avoid the creation of ground loops with shielded cabling.
1.5.3 Supported Fiber Optic Cables
The following fiber optic cable types are supported under the stated conditions.

The Precision Time Protocol (PTP) module adds the ability to provide time
synchronization via Ethernet using the Precision Time Protocol (PTP) and Network
Time Protocol (NTP), and to synchronize with an external IRIG-B source or GPS
network.
The PTP module features BNC ports for AM OUT, TTL IN/OUT and GPS IN. It also
includes an LED to indicate when synchronization has been achieved.
Note
The PTP module can only be installed in slot 6. For more information, refer to

1.6.3 AM and TTL Outputs
The PTP card provides AM (Amplitude Modulated) and TTL (Transistor-Transistor
Logic) outputs.
The AM OUT port supports the IRIG-B AM signal format, while the TTL OUT port
supports the IRIG-B PWM and PPS signal formats. Enabling/disabling the output ports
and – in the case of TTL OUT – selecting the signal format is controlled through the
RUGGEDCOM RSG2288 operating system.
NOTICE
The input impedance of third-party AM inputs must be 100 Ω minimum.
The number of devices that can be connected to the AM OUT and TTL Out ports is
dependent on the cabling type and length, as well as the input impedances of the
devices. The following simplified circuit schematic shows the interface between an
IRIG-B source and connected devices.
