RT-CDM  the single green countdown are using isolated RS485 and access to Wireless Mesh Networks constitute of the LANs, offers 255 nodes、250K rate、1.5 km distance and the detection of digital damage, for the real-time、reliability、expansibility and so on needs to be carefully to design. Strictly enforcement of the road traffic signal countdown displays (GA/T 508-2004) the relevant standards.

Advantages:

● Based on wireless, ISM Things technology（MANET）

● Support the red / yellow / green tricolor countdown in seconds

● 2500V common-mode rejection the Lightning RS485 access

● Independent the red / yellow / green digital dimming function

● Compatible with two kinds of LEDON and international agreements NTCIP

● The detection of digital damage function

● Countdown the digital in advance to flashes display function

● High-speed pulse the synchronous signal to sampling techniques

● Scrolling drop half-time countdown the display way

●The Real-time Communications Priority self-learning function

Features:

 Accurate real-time countdown the remaining green light seconds can improve passage efficiency, in advance Flashing and three-color digital，can be able to reduce the rush the Red / yellow snap controversy.Can also be connected to the true solar time that multi-period digital dimming function. So that drivers can clearly grasp at any orientation signal status, Improve safe driving distance, Really let traffic participants "idea in mind" to pass. Using the high quality components designed strict production and the testing processes to ensure product safety and reliable operation in harsh environments,so that to build a high-availability, cost-effective, powerful, leading intelligent transportation equipment as to the goal.
