· RS232 data can be sent from the dialing codec to all end-points of a multi-unicast
connection. Note: Bidirectional RS232 data is only available on the first connection
dialed when multi-unicasting.
17.10 Monitor Control Port I/O Status
It is possible to monitor the status of the two relay inputs and two opto-isolated outputs available
using the DB15
CONTROL PORT IN / OUT connector. To monitor status:
1. Press the SETTINGS button.
2. Use the navigation buttons to select Control Port I/O and press the button.
3. Select Inputs and then press the button to view input status.
4. Select Outputs and then press the button to view output status. Select an output and
press the button to toggle the output state from Off to On . Note: Input states cannot be
changed in this way.
17.11 Configuring TCP/UDP Ports
In TCP and UDP networks the codec port is the endpoint of your connection. Software network
ports are doorways for systems to communicate with each other. For example, several codecs in
your studio may use the same public static IP address. Unique port numbers can be used to port
forward audio to each codec.
Tieline Codec Default Port Settings
By default, the codec uses a TCP session port to send session data and a UDP port to send
audio. The session port uses the TCP protocol because it is most likely to get through firewalls –
ensuring critical session data (including dial, connect and hang-up data) will be received reliably.
The default session and audio port settings in Tieline codecs, for both TCP and UDP connections,
are outlined in the
Installing the Codec at the Studio section of the manual. This section also
contains useful information for configuring port forwarding and troubleshooting IP connections.
Changing Codec Port Numbers
Reasons for adjusting the port setting on your codec include:
