Make sure the correct communication cable is used between the MIO-CCE-3G/4K Port B and the ATSC
encoder. A null modem cable is used in almost all cases.
Avoid using gender changers, "home made" cables, or distribution boxes between the MIO-CCE-3G/4K
and ATSC encoder. Ensure a direct path is provided from the MIO-CCE to the encoder with a proper
working cable.
Ensure Port B is set to the proper protocol and baud rate using VistaLINK
Note: Only Port B supports SMPTE-333M and Grand Alliance protocol.
