The Maxon data radio with FSK module modification is a versatile solution for wireless applications. It supports baud rates from 1200 to 9600, AC/DC audio coupling, and advanced squelch systems (CTCSS, DCS, two-tone, and RSSI). With GPS data handling, adjustable power output, and a compact DE9 and BNC connector design, it ensures reliable performance.
Product Features:
- The Maxon SD-125E Series operates within the 148–174 MHz VHF frequency band.
- It supports 16 dip switch-selectable channels.
- It features an adjustable transmission power of 5W/1W for optimized energy use.
- It offers channel bandwidth options of 12.5 kHz and 25 kHz.
- It incorporates CTCSS, DCS, two-tone squelch, and RSSI-based squelch systems for interference management.
- The baud rates are configurable from 1200 to 9600, allowing flexible data transmission.
- AC and DC audio coupling enhance signal processing.
- Integrated GPS functionality enables seamless location-based data handling.
- A time-out timer prevents excessive transmission to maintain system integrity.
