An old genlock rig using MewPro 2 with Hero 3+ Black and Genlock Dongle can be upgraded to Hero 4. The post explains migrating from Hero 3+ Black to Hero 4.
Example Rig Migration
Suppose you have a 6-camera rig that consists of
- 6 GoPro Hero 3+ Black cameras
- 5 MewPro 2 boards
- 1 GoPro Dual Hero
- 1 Genlock Dongle
and these are connected in single dongle configuration:
Then the GoPro Dual Hero bacpac and the Genlock dongle are not necessary from now on. And now you’ll need one more MewPro 2 board and one MewPro Iliad as well as 6 Hero 4 (Black or Silver) cameras.
Remove the Dual Hero bacpac and the Dongle from your rig. Replace Hero 3+ Black to Hero 4. Burn the “MewPro4” software (https://github.com/orangkucing/MewPro4) to MewPro 2 boards.
The connection to each MewPro 2 board is the same as in single dongle configuration, however, TRIG signal is not used for Hero 4. And since Hero 4 can be fed power from side USB or herobus and works without internal battery the spare wire previously used for TRIG can be reused to connect 3.3V power from Iliad to each MewPro 2 board.
