Note 1: Upon receiving a Slave Transmit request from a Master Receiver device on
the I
2
C Bus, the iPort/LAN 2 outputs a Slave Transmit Request to its Host device,
and initiates an I
2
C Clock Stretch (SCL Low) until a Slave Transmit command is
received from the Host computer. While clock stretching, no other messages can be
transmitted on the I
2
C Bus.
Note 2: The tilde (~) character and the Carriage Return (CR) characters are used as
special marker characters within all iPort/LAN 2 transmitted text messages. These
characters may not be used within the text of a message, but must be replaced by
the following "Hex equivalent" characters:
Tilde replaced by "~7E"
Carriage Return replaced by "~0D"
iPort/LAN automatically translates "Hex equivalent" characters to their single-byte
value for transmission across the I
2
C Bus.
All entered data bytes are transmitted to the requesting Master Receiver device.
Slave Transmit stops upon receiving the first negative acknowledgment (Nack)
from the Master Receiver.
