Precision Time Protocol (PTP) Support
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 Chapter 3,
Communication Ports.

Section 1.3.1
Supported Time Synchronization Sources
The following time synchronization sources are supported by the RUGGEDCOM RSG2288, with or without the
PTP card:
NTP (Network Time Protocol) is the standard for synchronizing the clocks of computer systems throughout the
Internet and is suitable for systems that require accuracies in the order of 1 ms.
IRIG-B PWM
IRIG-B time synchronization is an even older, established, inter-device time synchronization mechanism providing
accuracy in sub-milliseconds.

üü

GPS
The Global Positioning System (GPS), as a source of accurate time, requires an external GPS antenna input to
provide accurate time signals comparable to 500 ns. The RUGGEDCOM RSG2288 can use the GPS receiver on
the PTP module to provide the time base for the system.

Installation Guide
IEEE 1588
IEEE 1588 is designed to provide networked, packet-based time synchronization between different networking
nodes (PTP devices). The RUGGEDCOM RSG2288 supports PTP v2, which is defined in the IEEE 1588-2008
standard. IEEE 1588 is designed to fill a niche not well served by either of the two older, dominant protocols,
NTP and IRIG-B. 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.
The RUGGEDCOM RSG2288 supports ordinary clock, boundary clock and transparent clock modes. An ordinary
clock can be configured as either a Grandmaster Clock (GM) or a Slave Clock (SC) within the master-slave
hierarchy.
Every Ethernet port on the RUGGEDCOM RSG2288 supports IEEE 1588. For more information, refer to
Section 1.3.3, “IEEE 1588 Support”.
Section 1.3.2
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 ROS operating system.
Chapter 1
Introduction
IMPORTANT!
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.
Figure 3: IRIG-B Simplified Circuit Schematic
1. Source 2. Cabling 3. Device
The maximum number of devices (N) that can be connected to the source is determined by checking if the source
current (IS) required to drive the connected devices is less than the maximum drive current the source can
provide, and verifying that the load voltage (VL) the connected devices see is greater than the minimum required
voltage.

NOTE
For detailed dimensions of the device with either rack, DIN rail or panel hardware installed, refer to
Chapter 5, Dimension Drawings.
The following sections describe the various methods of mounting the device:
• Section 2.1.1, “Mounting the Device to a Rack”
• Section 2.1.2, “Mounting the Device on a DIN Rail”
• Section 2.1.3, “Mounting the Device to a Panel”
Section 2.1.1
Mounting the Device to a Rack
The RUGGEDCOM RSG2288 can be secured to a standard 48 cm (19 in) rack using separately purchased rack
mount adapters. The adapters can be installed at the front or rear of the chassis.
Each adapter kit includes four adapters.
CAUTION!
Vibration hazard – risk of damage to the device. In high-vibration or seismically active locations, always
install four rack mount adapters (two at the front of the chassis and two at the rear).
CAUTION!
Electrical/mechanical hazard – risk of damage to the device. Before installing the device in a rack,
make sure of the following:
• When installing the device in a closed or multi-device rack, be aware that the operating ambient
temperature of the rack may be higher than the ambient temperature of the room. Make sure the
rack is installed in a suitable environment that can withstand the maximum ambient temperature
generated by the rack.
• Make sure each device in the rack is separated by at least one rack-unit of space, or 44 mm (1.75
in), to promote convectional airflow. Forced airflow is not required. However, any increase in airflow
will result in a reduction of ambient temperature and improve the long-term reliability of all equipment
mounted in the rack space.
• Do not exceed the maximum number of devices or weight restrictions specified by the rack
manufacturer.
• Do not overload the supply circuit. Refer to the over-current protection and power supply ratings
specified by the rack manufacturer.
• Make sure the rack and all devices have a proper ground-to-Earth connection. Pay particular
attention to power supply connections other than direct connections to the branch circuit (e.g. power
strips).
To secure the device to a standard 48 cm (19 in) rack, do the following:
NOTE
The device can be ordered with the communication ports located at the front or rear of the device.
Placing the ports at the rear allows all data and power cabling to be installed and connected at the rear
of the rack.
1.Make sure the rack mount adapters are installed on the correct side of the chassis.
