3.3.2 Card Edge Serial Port
The 4-pin header at the card edge (J8) contains a serial port that must be used to set the IP address of
the card. This requires an Evertz WA-S76 rainbow cable, also known as a 7700 Upgrade Cable. This
cable is shipped with every Multiframe and is common to all 7700/7800 modular cards.
