Sending an I

C message with doStop enabled will cause the message to be

terminated with a Stop Condition. Sending an I

C 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.

Enter the hexadecimal data you want to write to a slave receiver device, or the

number of data bytes to read from a slave transmitter. Message Center

supports up to 32 bytes of 8-bit data per message.

NOTE: The data you send may have special meaning to the receiving slave

device, but to the Message Center, and the I

C adapter, message data has no

special meaning. Consult your slave device’s data sheet for details.

Click OK to accept the message and enter it into the spreadsheet.

Master Write messages display the message data in the spreadsheet. Master Read

messages display 0xFF placeholders in the spreadsheet. Upon execution, actual data

received from a slave transmitter replaces the placeholders in the message

spreadsheet.

Repeat above steps for additional messages. The Message Center supports up to

32,000 messages in a list.

4.1.7 Inserting and Deleting Messages

You can insert a new message between existing messages by clicking once on a

message below where you want to insert, then press the “Insert” key on your

keyboard. The Message Editor also remembers the last message displayed, so

double clicking on a blank spreadsheet row will allow you to copy a message.

Delete a message by single clicking on the message row and pressing the “Delete”

key on your keyboard.
