- Built-in error detection/correction for maximum data integrity
Applications include remote file transfer, RTK, OTF and
Differential GPS - Lightweight, moulded weatherproof housing conforming to IP65 12.5kHz or 25kHz channel spacing
- 10mW, 500mW or 2W transmitter power output
- 10W base station variant in marine grade IP67 housing
- Individual channel squelch level setting via front panel switch or serial set up
Designed using the latest technology, Tracs-COM is ruggedly built to meet mobile and static data transmission requirements including land survey RTK, land seismic exploration, mobile tracking and monitoring, agricultural land management, Differential GPS applications and SCADA. Tracs-COM can be operated in Rx only mode, Tx burst mode, Tx continuous mode, Tx/Rx mode and repeater mode. Repeater mode provides a secondary link to extend the operating range in areas where direct communication is obstructed. The system uses Gaussian Minimum Shift Keying (GMSK) with a sophisticated error detection and correction code to ensure that the data is received reliably even under adverse conditions. External data interface is via two RS232 serial ports at rates up to 19,200 baud. The over-air bit rate is selectable for optimum performance at different ranges. Operating parameters are easily set up through the RS232 interface using a supplied PC program. Link status is displayed by front panel LED indicators. Channel selection is by means of a front panel switch or via a serial setup message
