Firmware update information Last updated : November 17, 2016
The HF/50MHz All-mode transceiver TS-590S firmware has been updated from Version 2.02 to Version 2.03 as follows.
We are offering the firmware updating program to the TS-590S owners.
You can update the TS-590S firmware by connecting the TS-590S to the PC by using a USB cable or an RS-232C cable.
The firmware updating program is not applicable for the TS-590SG.
The TS-590S is no longer in production. The firmware updating program Ver.2.03 is applicable for all units of the TS-590S.
Attention
Updating the firmware from Ver.1.08 (or before) to Ver.2.03 resets the transceiver automatically due to internal memory address reallocation. If you do not want to lose user data, save the data using the latest version Radio Control Program ARCP-590 (Ver.2.02) before updating the firmware and write the data back after updating the firmware.
About virtual COM port driver
A virtual COM port driver needs to be installed onto the PC to use the firmware updating program with a USB cable.
ATTENTION:Do not connect the transceiver to a PC using a USB cable before installing the virtual COM port driver.
