4 iPort Message Center The iPort Message Center supports I2C Master Transmit and Master Receive activities for all MCC I2C Bus host adapters. With this program you can create, save, and execute scripts of I2C Master messages. Main Application The iPort Message Center allows a PC to become an I2C Master transmitter or receiving device, sending I2C messages between the PC and one or more I2C devices across an I2C Bus.
4.1 Message Center Operations Communicating with another device on the I2C Bus is easy. Just install the software as described in Section 3, then following these simple steps: 4.1.1 Starting the Message Center Click, Start *Programs *iPort Utility Pack*iPort Message Center 4.1.2 Selecting the Adapter Select the I2C adapter you are using by clicking the corresponding adapter image (see Opening Screen), or the Device Select checkbox (see Main Application Screen).
4.1.3 Select the Communications Port Use the “Using Com:” control to select the RS-232 communication port connected to the I2C adapter. Message Center supports USB and network connected local or remote RS-232 ports via the Windows Com driver. 4.1.4 Options Menu Use the Options menu to override default Baud Rate and I2C Bus Clock rate settings. Default settings and options are adapter dependant. 4.1.
Use the I2C Message Editor to: 1. Set I2C Address. The I2C Address is the I2C slave address of the slave device being addressed on the bus. All slave addresses are displayed as even numbers (00...FE), representing the 7 most significant bits of the 8-bit slave address transmitted on the bus (aaaa aaa0). The I2C adapter automatically supplies the 8th, least significant, Read/Write bit when it sends the slave address across the bus.
Sending an I2C message with doStop enabled will cause the message to be terminated with a Stop Condition. Sending an I2C message with doStop disabled will cause the message to end without a Stop Condition, allowing the next message to be sent with a Repeated Start. 4. Set Time Delay. Message Center supports time delays after the completion of a message. Time delays can be used to synchronize or sequence bus messages with the activity of external devices. 5. Specify Write Data or Read Byte Count.
4.1.8 Saving or Loading Message Lists Message Center I2C message lists can be saved to, or loaded from, a disk file. To save the current message list, click File|Save on the menu bar.

Diagnostic Set Up Screen 5.1.3.3 Diagnostic Setup (on supported adapters) On the Diagnostic Set-up screen you can set the following parameters: Log File Level A log file is available to troubleshoot RS-232 communication problems with the selected communication port. The log file is an ASCII text file viewable with any text editor. Select logging level. Level 1 provides minimum information. Level 4 provides maximum information. Log File Name Specify a log file name.
5.1.4 Sending I2C Messages 5.1.4.1 Master Operations 5.1.4.1.1 Specifying the Destination Address The Destination Address is the I2C slave address of the slave device being addressed on the bus. All slave addresses are displayed as even numbers (00...FE), representing the 7 most significant bits of the 8-bit slave address transmitted on the bus (aaaa aaa0). The I2C adapter automatically supplies the 8th, least significant, Read/Write bit when it sends the slave address across the bus.
5.1.4.1.3 Auto Repeat The situation often arises, where you would like to automatically repeat a master message operation. The Message Manager supports auto-repeat with the Auto Repeat checkbox. You can automatically repeat a master operation by checking the Auto Repeat control before clicking the Master Tx, Master Rx, or Master TxRx buttons. The master operation repeats until the Auto Repeat control is unchecked. 5.1.4.1.
Click OK to accept the data. Sending Master Transmit Messages Click the Master Tx button to write the specified Master Tx Data Bytes to the selected destination slave device. If Auto Repeat is checked, the message will automatically repeat upon completion. The Communications Events window on the main screen should report “Master Tx Complete.” If this message does not appear, check the slave device address, connections, and power.
Negative Acknowledge Last Byte On supported adapters, the doNak checkbox gives you the option to acknowledge, or negatively acknowledge, the last byte read from a slave device. Some Slave Transmitter Devices require a negative acknowledgment on the final byte read from the slave device. I2C adapters not supporting this option automatically negatively acknowledge the last byte read. 5.1.4.1.
