Explanation of Signals
Control signals are comprised mainly of 8-bit identification signals and of the data signals added to them. Data signals are
added to DIS and DCS signals.
Signal.....DIS (Digital Identification Signal)
Identification Signal Format.....00000001
Function:
Notifies the capacity of the receiving unit. The added data signals are as follows.
(Example)
