Firmware Update

From time to time, Datavideo may release new firmware to either add new features or to fix reported bugs in the current DAC-91 firmware. Customers can update the firmware themselves if they wish or they can contact their local dealer or reseller for assistance should they prefer this method.

This section describes the firmware update process and it should take approximately few minutes to complete. Once started, the update process should not be interrupted in any way as this could result in a non-responsive unit.

1. Latest firmware files
   ♦ Firmware 1: MCU
   ♦ Firmware 2: FPGA

2. A Male USB A to Male mini-USB cable not longer than 2 meters

3. A Windows PC with USB 2.0 ports

Firmware 1 Update Procedure

1. When power is not connected, set DIP SW 2-4 to 110 as shown in the diagram below:
   

2. Connect the DC 12V Power:
   PWR LED will be turned ON and the device will enter the Firmware 1 update mode.

3. Connect the PC via mini-USB port and the “ Removable Disk ” dialogue box will appear on the PC (if the device is connected to the PC for the first time, you will then see a “ DAC-91 Datavideo FW1 USB Drive ” prompt appearing at the bottom right corner of the screen). You will see an empty drive after it is opened.
   

4. Copy the MCU Firmware 1 file (DAC-91-FW1-V1.xxBIN) to the removable disk and after about five seconds, the user should be able to see the file:
   

5. Click on the “Safely Remove Hardware and Eject Media” icon to eject the Datavideo Removable Disk. After the “Safe to Remove Hardware” prompt appears, disconnect the mini-USB cable and unplug the DC 12V power.

   ♦ Set DIPSW 2-4 to a setting other than 111 or 110, for example, you can set DIPSW 2-4 to 000.
   ♦ Connect the DC 12V power and the PWR LED will be turned ON.
   ♦ After 7 seconds, the Audio LED will be turned ON and then faded out, indicating that the device is functional and the update is successful.

Firmware 2 Update Procedure

1. When power is not connected, set DIP SW 2-4 to 111 as shown in the diagram below:

2. Connect the DC 12V Power:
   PWR LED will be turned ON and the device will enter the Firmware 2 update mode.

3. Connect the PC via mini-USB port and the “ Removable Disk ” dialogue box will appear on the PC (if the device is connected to the PC for the first time, you will then see a “ DAC-91 Datavideo FW2 USB Drive ” prompt appearing at the bottom right corner of the screen). The disk name is DAC91FW2XXX (XXX corresponds to the previous version number X.XX). You will see an empty drive after it is opened.
   

4. Copy the FPGA Firmware 2 file (DAC-91-FW2-Vx.xxBIN) to the removable disk and the update will finish after about 30 seconds:
   

5. Click on the “Safely Remove Hardware and Eject Media” icon to eject the Datavideo Removable Disk. After the “Safe to Remove Hardware” prompt appears, disconnect the mini-USB cable and unplug the DC 12V power to complete the update.
   Remark: When DIPSW 2-4 is set to 111, you can check the disk drive label for the updated firmware version if the mini USB connection is not removed and the power is still connected.
   

6. To check if the update is successful:
   ♦ Set DIPSW 2-4 to a setting other than 111 or 110, for example, you can set DIPSW 2-4 to 000.
