Updating the firmware

Use this procedure to update the firmware of the receiver, charging station, and transmitter to the latest version.

  1. On the menu, click “Tools” -> “Firmware Update”.

    The Wireless Firmware Update Tool will launch.

  • An internet connection is necessary to download the firmware.
  • There are two types of the ESW-R4180DAN: the “ESW-R4180DAN” and the “ESW-R4180DAN (S-1)”. The firmware differs between these two receivers. Although incorrect firmware will not install, it is best to confirm your receiver type before updating the firmware. You can check the type of your receiver by consulting the rating label on the back of the unit. For the “ESW-R4180DAN (S-1)”, “S-1” is written on this label. You can also check the type of the receiver by viewing the "Version" section of the “Device Setting” screen in Wireless Manager.

Installing the firmware

Install the downloaded firmware to the device.

  1. Current installation statuses are displayed.

    • Click “Download” or “Install” to switch between the two tabs.

    1. Click the icon to refresh the display.
    2. Displays the current firmware version of the device.
    3. Displays downloaded firmware versions.
    4. Click the button to close the “Wireless Firmware Update Tool” screen.

  2. Select devices to install the firmware by clicking “Add to Queue”.

  3. Click “Install Queued”.

  4. Click “OK”.

    Firmware installation will start. Perform the installation by following the on-screen instructions.

  5. Installation results will be displayed once installation is complete.

    • If “Error” is displayed, the installation has failed. If the “Retry” button is enabled, restart the firmware installation. If the “Retry” button is disabled, a malfunction may have occurred. In this situation, contact your local Audio-Technica dealer.
    • If “Missing” is displayed, the installation has failed. Make sure that the network is connected properly. Also make sure that the transmitter has been inserted properly into the charging station. If the info icon is displayed next to “Missing”, also check this icon. After checking all these items, click the update button in the upper-right corner of the screen to carry out the installation again. Perform a forced update if the device cannot be detected. If the firmware update process is interrupted, “Unknown Tx” may appear as the model name for the transmitter. This is normal, so please reinstall the update.
  • When installing the firmware, make sure that the transmitter is inserted into the charging station.
  • When installing, do not remove the transmitter from the charging station.
  • Dirt easily adheres to the charging terminals of the transmitter and charging station. The firmware update operation may fail if these products are used with dirty terminals. If these terminals are dirty, wipe away this dirt with a cotton swab or something similar. Be careful not to apply too much force when doing so.
  • The transmitter battery will continue to drain if the firmware installation fails. If the transmitter is left as is, its battery will drain until it is almost empty, at which point it will not be possible to install the firmware, so immediately carry out the installation again.
  • To enable installation again on a transmitter whose battery is almost empty, insert the transmitter into the charging station and perform preliminary charging. During preliminary charging, one status indicator lamp on the charging station flashes in red.

When firmware installation fails and the device is not detected (forced update mode)

If firmware installation fails, the device may not be detected by Wireless Manager. However, running forced update mode in this situation will enable the device to be detected.

  1. Set the IP address of the PC to the same segment other than “192.168.0.20/24”.

    • If the firmware installation fails, the failed device will start up on “192.168.0.20/24”. Therefore, the PC must be set to the same segment other than “192.168.0.20/24”.
    • It is necessary to manually switch the charging station to forced update mode. With the charging station off, press and hold its reset button and turn it on. Continue to hold down the reset button (for approximately 10 seconds) and release it when the power indicator lamp flashes in blue. The charging station switches to forced update mode.

  2. On the “Wireless Firmware Update Tool” screen, click “Forced Update Mode”.

  3. Select a device.

    • When a connection with the device is established, “Established” is displayed for “Device Connection”.

  4. Click “Start”.

    Forced update mode will start.

  5. Once forced update mode finishes, click “Close”.

    • If an error occurs, restart forced update mode.

  6. Restart firmware installation.
