BSV TR-14

The trolleybus controlled unit over the RS-485 bus of the BSV system is characterized by FSK modulation in the area above 120 kHz (free band according to General License No. VO-R/10.3.2007-4 Article 10 with a transmission rate of 4800 bit/s. The length of the transmitted payload information is typically 36 bits. Security is by CRC-12 code. A rate of 4800 bit/s means that one data frame is transmitted in about 15 ms. In that time, the trolleybus travels a distance of 15 cm at 36 km/s.

Basic features: 

• Inductive build method in 125 kHz frequency modulation band (FSK)
• Generation II - transmitting transmission rate of 4.8 kbit/s
• Automatic adjustment of the resonant frequency of the transmitting circuit
• Control via RS 485 interface or current loop
• Single +12V to +30V power supply
• Transmitted data is secured by CRC-12 method
• Low power consumption of the unit - up to 6W
• Remote adjustment of transmitted power
• Output isolation > 5 kV
• Easy installation
• Can be used for intersection preference
