Maxon SD-1710EX-V Data Radio of RF wireless modems offer Phase Lock Loop Synthesizer (PLL) microprocessor controlled and offer one to five watts of power with 16-channel capability. Programmable sub-audio squelch system (CTCSS & DCS) and two-tone squelch system are newly added to the signal level detect squelch system (RSSI). GPS Data handling is provided to interface and control internal GPS receiver. The SD-170EX Series incorporates the most often requested mechanical footprint, DE9 male connector, and BNC antenna connection. Maxon has been a trusted name in the data/telemetry market for over 20 years.
