Product overview
The ComNav CDL5 UHF External Datalink provides transmit, receive and repeater functions for GNSS RTK survey systems. It operates in half-duplex mode across 410-470 MHz, with field channel changes, 12.5 kHz channel spacing and selectable 9600/19200 bps air baud rates. Repeater operation relays real-time data to extend working coverage. Transparent, South, Mac and TT450 protocols support communication with compatible datalink products. Six selectable transmit power levels—2W, 5W, 10W, 15W, 20W and 30W—provide a range of output settings.
A fully metal enclosure provides IP67 dust and water protection, including temporary immersion to a depth of 1m. The CDL5 is designed to survive a 2m drop onto concrete and operates from -40°C to +75°C. It weighs 1.3 kg and measures 11cm × 18cm × 9.3cm with its connector. Connections comprise a 7-pin Lemo serial port, a 2-pin Lemo power port and an external 50 Ohm N-TYPE female RF connection. A digital display and dedicated power, channel and power selection buttons provide local control.
