Flymaster devices have undergone several manufacturing series that use different communication protocols. On the Flymaster site, we apparently no longer find the communication drivers alone. Flymaster Designer can be downloaded with drivers included. Problem : this will not work with the first scale (B1/B2).
The Flymaster USA importer has done an excellent job of summarizing the various devices. This table can be consulted on theirsite. However, the link on the referenced driver 2.08.30 is dead. On the site FTDI, we were able to find a driver with the same reference that works… You can download this driver on our website.
