Information for Yaesu FTDX101D(MP) and FTDX10 users
For communication between the radio and amplifiers OM2500A / OM4000A / OM3500A use FT991 setting. If FT991 is not
present in your current firmware, please contact us and inform us about your amplifier model and S/N.
Upgrading firmware and restoring EEPROM
If you have a newer version of firmware in your power amplifier (see table), you can upgrade it or backup/restore
EEPROM with Firmware loader software v3.7 from our download section.
This process can be done over the serial port or LAN for automatic power amplifiers and only through serial port
for manual power amplifiers.
| Amplifier type | FW versions for Loader v3.7 |
| 4001A, 3501A, 2501A | 2.42 and above |
| 4001HF, 3501HF, 2501HF, 3006+ | 2.29 and above |
| 2000A+ | 4.33 and above |
In case you have an older version of firmware in your amplifier (lower then in table), you can upgrade it
only through serial port with the older Firmware loader software v2.8. You can download it through
this link.
