CTR-BlueLync: Serial

Our CTR-BlueLync Serial interface supports the RS232 interface used on Kenwood TS-2000 and Yaesu FT-1000 radios and other radios. The interface is shown with a DB9 female serial port connector for the FT-1000. Other radios may require a male connector.

NOTE: This interface does not provide "true RS232" signal levels. Its output is 0 (logic high) and +12 VDC (logic low) instead of -3 VDC or less for logic high. Most radios using RS232 interfaces accept these voltages.

CTR-BlueLync has been tested on the following devices and found to function satisfactorily (thanks Ken, W7KKE):

  • KAM+ @ 9600 baud
  • Kenwood TM-D700 @ 9600 baud
  • Garmin GPS-III+ @ 4800 baud
  • Kenwood TH-D7 @ 9600 baud
  • Yaesu FT-847 @ 9600 baud
  • Yaesu FT-857D @ 9600 baud
  • Nasa Marine AIS Engine @ 38400 baud

The interface requires external voltage (5 to 15 VDC) and is shown with a standard 2.1 x 5.5 MM coaxial power jack (center +) that fits many "wall-wart" type power supplies. You can also power the unit from the radio's power supply.

The schematic and board layout for this unit are shown below. The interface can be built on a standard perf-board.

Far Circuits carries the circuit board kit (under "Keyers") and the BlueSMiRF modules can be found at www.SparkFun.com. Contact these vendors directly for prices and availability.

The completed interface fits neatly in a Hammond 1551H plastic enclosure. The heads from clear plastic thumb tacks make excellent lenses for the BlueSMiRF LEDs.
