• Signal State - shows if the signal is present and error free.
• DMX Rate: shows the number of DMX frames per second.
• Slots DMX: shows how many data slots are in the DMX packets.
• MBB: Mark Before Break - high value pause at the end of the last data
packet, of variable length.
• BRK: Break - low value pause to denote the beginning of a new data
packet.
• MAB: Mark After Break - high value pause to separate break from the
ensuing data.
