Data-Linc Modems support solar car project

Data-Linc Group provided Power of One solar car project with the SRM6210E wireless Ethernet modem for transmitting crucial telemetry data. The project utilizes top-of- the-line technology from all fields of engineering. When complete, the car will attempt to set a distance record by crossing the North American continent twice via the Transcanada highway starting in Toronto, ON, proceding east to St.John's, NL and then heading west to finish in Victoria, BC.

Requiring highly reliable and hassle free equipment, the project's Electronic Integration team chose Data-Linc Group’s SRM6210E. The solar car and its support vehicles will be equipped with the wireless Ethernet radio modem. The radio modems will be used to transmit important backup monitoring data including temperature, power status and energy consumption.

The project mission statement is “To fulfill a dream and inspire others to accomplish their dreams in a positive way to benefit mankind and the environment” with a commitment to the promotion of clean and sustainable energy.

Data-Linc Group is proud to be a part of this endeavor and wishes the Power of One team ultimate success. Track their progress.

Shipping: Tug to Barge Communication in the Gulf of Mexico

Two of Data-Linc's license-free wireless modems are part of a system that provides data communication between a tug and its barge in the Gulf of Mexico. The control console in the bridge on the tug is connected to a PLC which interfaces with Data-Linc's license-free SRM6000 radio modem. The control and feedback signals are transmitted bet ewe en the SRM6000 via omni directional antenna on the tug to a second SRM6000 with an omni directional antenna connected to another PLC on the barge allowing the tug to control lighting and other devises. The SRM6000 radio modems transmit data from the PLC to provide input and consolidation of command console inputs for the control. (See diagram)

Supervisory Data Collection of Track-side Signals

A major urban Mass Transit Authority selected Data-Linc Group MDL500 FSK Modems for a track-side data collection system. They required a modem with multi-drop ability and exceptional immunity to noise. The MDL500 was the perfect choice to withstand railcar induced surges of over 200V. Its features include:

• Transparent operation over two copper wires
• Long range communication of up to four miles with multiple drops
• Transformer isolation for surge protection to 1500 volts

Remote Control of Hydraulically Operated Rail Switch Stands*

The Data-Linc SRM6000 Radio Modems were chosen for license-free operation, positive visual feedback/status confirmation, high performance, long-range and simple operation. The system provides:

• Operation in license-free 902-928 MHz band
• High level of security that prevents unauthorized external access
• Visual status indicators of all switch positions
• Reliable communication in high interference conditions
• Excellent transmission in rail yard environments- even between railcars
• Push button controls that can be operated while wearing gloves
• Extended operating temperature of -40° to 167°F (-40° to +75°C).

^*This system was co-developed with FGR Automation, Inc. for control of
the Railway Technology, Inc. Hydra-Switch.

Data-Linc Radio Modems Used for British Columbia Ferry Corporation

Historically, on-ship personnel had to keep manual maintenance logs and other records, which were later entered into BC Ferry’s computer network after the vessel reached shore. The project started using a commercial wireless Ethernet system, which provided an Ethernet interface and a radio frequency (RF) data rate of 2 Mbps but communication could occur only when the ship was at or near dock. BC Ferry wanted continuous data communications – even when the vessels were 20 to 30 miles out to sea. But the commercial units weren't designed for such a range. Data-Linc Ethernet radio modem offered a highly sensitive RF receiver combined with a reasonable data rate that supported long range communication without requiring a parabolic directional antennas.
