iPort Message Manager Software for Windows
Introduction to Message Manager
The MCC iPort Message Manager Software, when used in
conjunction with an MCC iPort allows a PC to become an I
2
C
Master or Slave device, transmitting or receiving I
2
C messages
between the PC and one or more I
2
C devices across an I
2
C Bus.
The iPort Message Manager is designed to be a simple application
for experimenting with I
2
C messages. It provides methods to:
1. Set the device’s I
2
C Slave address, General Call Enable, and
other operating parameters.
2. Master Transmit ASCII text or Hex [~00...~FF] data to a
specified I
2
C Slave Receiver device.
3. Master Receive data from a specified I
2
C Slave Transmitter
device.
4. Perform Master Read after Write operation.
5. Slave Transmit data to a requesting I
2
C Master Receive device.
6. Display Slave Receiver data.

7. Assert or release the INT signal (iPort/AFM only).
Each iPort Message Manager I
2
C message can include up to 23
bytes of 8-bit ASCII binary data, although the iPort itself is capable
of sending or receiving I
2
C messages up to 64K bytes in length.
