V-4EX: How to Update

Items Needed:

  • V-4EX Hardware

  • USB 2.0 cable, Type A to Type B

  • A computer with a USB 2.0 connector ( Windows 8 / 7 / Vista / XP, MacOS X )
    • Note that MacOS 10.15.4 Catalina may not work, please use an earlier version
  • V-4EX RCS for Windows or V-4EX RCS for Mac OS X




  • Never apply this update data to any product other than the V-4EX. This update data may destroy the data or system program of other products.

  • Never power-off your V-4EX while the update is in progress! If a power failure or similar accident occurs during the update process, the V-4EX won’t be able to start up in normal operating mode. This will require service, please contact support if this occurs.





Step 1

Get the System Program Firmware update file from the V-4EX Downloads Page.

Click on the System Program link, scroll to the bottom of the page, and download the .zip file.





Step 2

Please open/extract the downloaded “v4ex_sys_v1530.zip” file on your computer to access the .bin update file in the “v4ex_sys_v1530” folder.



Do not open this file, it is not a program or installer. You will later upload it to the V-4EX using the RCS software.


Step 3

If you have not already, download the V-4EX RCS Software from the V-4EX Downloads Page.

Once downloaded, extract the contents of the .ZIP file, and run the program on your Windows PC or Mac.

The Windows version does not have an installer, the program is contained entirely in the .exe file.



Step 4

Connect the V-4EX and your Windows PC or Mac with a USB 2.0 cable.


Step 5

Power-on the V-4EX while holding down the [MENU] and MONITOR [INPUT] buttons on the V-4EX panel.



Keep holding those two buttons down until the four INPUT SELECT buttons on the right-hand side of the V-4EX all flash green repeatedly.



Step 6

Start the V-4EX RCS software that you downloaded, and click the [Update] button.


The Update dialog box appears and the top "V-4EX" text field should read, "Update Mode".

If it displays "---", disconnect and reconnect the USB cable.



Step 7

Drag the program file "V4EX_ver1530.bin" to the Update Mode dialog box and let go of your mouse button to drop it in.


Check that the following appears:
version: 1.530
V-4EX Video Mixer

Step 8

Click [ Update ] on the dialog box to start the update.

When the update is completed, the message "Update Complete" appears and the V-4EX is automatically powered-off.



Step 9

Disconnect the USB cable and power-on the V-4EX.

Step 10

Check that the update has succeeded by following the steps in "How To Tell The Version".
