Arduino Shield - Camera power control?

Are there any commands that can be used to control the on/off power of a connected camera? No commands are listed in the shield manual, but I think the ATEM can do such control. If so, shouldn't it be possible to send the same commands via the shield?

Hi Bill,

It is possible to power on/off via the Bluetooth Camera Control protocol only. There is no equivalent command in the SDI Camera Control protocol.
