The H-Link is the connection between an H2000 or H3000 and a PC. It is also used to connect the H3000 to the Zeus unit (not the Zeus Touch).

There is some difference between H2000 and H3000 H-link:

  • Different connector
  • H2000 has a <CR> as a delimeter
  • H3000 has a <CR><LF> as a delimeter
  • H3000 uses a checksum (8 bit exclusive OR, http://www.lammertbies.nl/comm/info/crc-calculation.html) at the end of the sentence (e.g. *2F)
  • H3000 speed: Baud Rate 115200, Parity  None, Data bits  8, Stop bits  1
  • H2000 speed: Baud rate      9600, Parity  Even,  Data bits  7, Stop bits  1 (default RS232 setting: 6.2)
  • Columns and rows are swapped for polar and other calibration tables
  • Less commands?
  • H2000 is not compatible with the Zeus Touch
  • H2000 H-link uses the RTS and CTS options

Also the H3000 has 2 "levels" of H-link, H-link LT and H-Link Pro, the Pro is only available at H3000 systems with polars, the Hercules Performance and Hercules Motion. This is because the polar data is only available at the Hercules Performance and Hercules Motion. H-Link LT only gives you access to the True Wind Correction tables
