Writing Output Data

Since the serial device uses STX and ETX, configure the DeviceMaster to
automatically append STX and ETX for all output data.
1. Open the DeviceMaster web page, click Serial | Port 1.
2. Configure the Tx Append Delimiters from PLC section as shown in the following
figure.
3. For the demonstration purposes, use a watch table to modify output value
directly as shown in the following figure. Enter the following values:
• Change tag TxSeqNum value from 0 to 1.
• Set tag TxLength value to 5.
• Enter an ASCII string EFGHI as the value in tags TxData0..TxData4.
