Figure 47. Bit Format of Character Data Being Transmitted in the Multi-Drop Mode
The “Master Station” communicates to the “Slave
Stations” by transmitting a character (typically a byte) with
an “Address/Data” bit flag appended to the end of the
character. This typically results in nine bits of being
transmitted for every character byte, as presented in
Figure 47.
When the “Master Station” wants to transmit a block of
data to one of several slaves, it first sends out an Address
byte that identifies the “Target Slave”. An address byte
differs from a data byte in that the ninth bit is a “1” in an
Address Byte and a “0” in a Data Byte.
