Important Note:
· WheatNet logic I/Os allow Tieline WheatNet-IP enabled codecs to activate functions
across a WheatNet-IP network. See Enabling Relays & RS232 Data for more info.
· A non-WheatNet-IP Tieline codec can be configured to trigger a WheatNet LIO in a Tieline
WheatNet-IP codec.
See the section titled Creating Rules for more information.
Configuring RS232 Data
Once Data is enabled, the codec can be connected to external devices and transport RS232-
compatible data via the serial port on the rear panel of the codec.
1. Press the SETTINGS button.
2. Navigate to System and press the button.
3. Select RS232 Config and press .
4. Use the navigation buttons to select the correct baud rate.
5. Next, press to toggle flow control On to enable flow control.
Important Notes:
· When connecting to G3 codecs only in-band data is available via the Music and
MusicPLUS algorithms. See RS232 Data Configuration for more details.
· It is important that you enable serial port flow control within the codec. Flow control
regulates the flow of data through the serial port. If disabled, data will flow unregulated and
some may be lost.
· Ensure you match the serial port baud rate to match the rate of the external device you are
connecting to. Ideally the settings on both codecs should match, or you could have data
overflow issues.
· Only the dialing codec needs to be configured to send RS232 data to another Tieline G5
or G6 codec. Session data sent from the dialing codec configures the answering codec.
· RS232 data can be sent from the dialing codec to all endpoints of a multi-unicast audio
stream if your codec is capable of these connections. Note: Bidirectional RS232 data is
only available on the first connection dialed when multi-unicasting.
