FT 817 Tested on This keypad has been developed on a FT817ND I Italian version with serial number SHOOxxxx The keypad firmware uses both CAT commands from the User s Manual and Internet pages detailing the extended command set for FT817 serial number 1D21 Given the combination above there are good chances that this keypad will work on all FT817 ND worldwide Reports of working keypad on your flavour of FT817 are welcome Doc v 20090418 7 IK1ZYW Keypad for FT 817 How it works This keypad is operated through the 4x4 matrix keyboard Several functions are programmed in the microcontroller and are accessible via one or more key press as detailed further down The keypad waits for a key press that initiates a command input sequence the green LED is lit if installed Each key press is confirmed by a short blink of the red LED if installed and the green LED goes off when the keypad is waiting for further input before sending data to the radio Once the sequence is complete the keypad microprocessor sends the appropriate command to the radio which should react accordingly and the green LED lights up Each key press is subject to 50 milliseconds of debounce and 200 milliseconds of repeat delay Keeping a key pressed longer than 250 milliseconds is equivalent to a second press These values have been found to be a reasonable compromise between dial speed and dial accuracy In order to minimize RFI and data corruption
