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.
