AXIOM photonSDI is an extension board that's designed to utilise both available module slots on AXIOM Beta Main Board adding 6G SDI connectivity to the camera's features.
 
The board has two independent 6G SDI outputs that can both output the same image, different images, or be used in a dual 6G configuration that allows the transmission of 4k video material at 60 frames per second. Additionally the board contains a 6G SDI input for synchronisation and blending and a legacy synchronisation input.

AXIOM photonSDI is an extension board that's designed to utilise both available module slots on AXIOM Beta Main Board adding 6G SDI connectivity to the camera's features.

The board has two independent 6G SDI outputs that can both output the same image, different images, or be used in a dual 6G configuration that allows the transmission of 4k video material at 60 frames per second. Additionally the board contains a 6G SDI input for synchronisation and blending and a legacy synchronisation input.
