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.
5.1.4.1.4 Master Transmitting Data
Specifying Master Tx Message Bytes
Master Tx Message Bytes is the ASCII or Hexadecimal data you want to transmit to
a slave receiver device. With the Message Manager, entering master transmit data is
easy. On the main application screen, click on the Master Tx Message Bytes box to
open the data editor.
In the data editor, enter one or more ASCII text characters or hexadecimal data
bytes. Each hexadecimal byte is entered as two ASCII-Hex characters (00 to FF)
preceded by a tilde (~) character. ASCII text and hex data can be intermixed, as
long as each hex byte is preceded by a tilde.
For example, to enter hex data bytes 0x00, 0x01, and 0x02, enter the characters
~00~01~02 into the text box.
Each iPort Message Manager I

C message can include up to 80 bytes of 8-bit ASCII
binary data.
NOTE: The data you send may have special meaning to the receiving slave device,
but to the Message Manager, and the I

C adapter, message data has no special
meaning. Consult your slave device’s data sheet for details.
