Wireless 900 MHz Frequency Hopping Data Radio

 T-SERIES RADIOS

License-free wireless data radio
(compatible with all leading brands of traffic signal controllers)
networks have been shown to be effective for traffic signal monitoring and control (170, 2070, NEMA), variable message signs, gate closures and other applications.
 


The new T-Series Family includes two models, the 900 MHz T-9 and the 2.4 GHz T-24. Both models employ proprietary frequency hopping technology to provide secure, reliable, error-free communications at line-of-sight ranges of up to 60 miles. Both models are designed to install into and draw power from a single slot in a standard loop detector card rack for convenient use with 170. 2070 or NEMA controllers. Both models are compatible with all leading brands of traffic signal controllers.

The T-Series models are fully compatible with the standard FGR 900 MHz or 2.4 GHz products and offer the same extensive set of features including user-programmable RS232/RS422/RS485 interface, 6 to 30 volt DC operation, 100% tested -40 C - +75 C operation, and 115.2 Kbps true network bandwidth. The T-Series models can be programmed to function as a master, slave, single-radio repeater, or single-radio slave/repeater. The number of radios that can be installed in a network is unlimited, and the number of repeaters that can be used in any network path is also unlimited.

The T-Series models are compatible with CommControl network management software and are provided with a two-year warranty.

Transportation Applications:

License-free wireless data networks have been shown to be effective for traffic signal monitoring and control (170, 2070, NEMA), variable message signs, gate closures and other applications. Whether deploying in municipal closed-loop systems or utilizing a regional transportation operations center with central control software, T Series  products deliver robust, reliable communications.
