Telemetry D Receiver upgrade USB/Serial lead interface
Part Number: FRS-FUL-1
The FUL-1 is basically a level converter that allows you to upgrade the firmware of the FrSKY telemetry DFT/DJT/DHT V1 transmitter modules and also the D8R V1 receiver to provide the following additional features: * Four different tones corresponding to four alarm sources * Improve the smoothness of servos when working with D8R * Provide two PPM modes: HS (9ms) if using high speed digital servos and FS (18ms) if using analogue servos. Please note that in telemetry (two-way) mode, both the module and the receiver need to be upgraded to V2 simultaneously; V1 and V2 are not compatible. This adaptor may also be used as a level converter for modified 9X radio installs with the FrSky system.
This adapter is NOT needed to update the firmware on the D8R-II or the D8RII-Plus.
