The asynchronous nature of the responses means that a user should never rely on the desired
update actually occurring and must simply watch for status updates from the Teranex Server and use
only these to update its local representation of the server state.
Timecode Syntax
Timecode values are expressed as HH:MM:SS:FF.
Checking Connection Status
While the connection to the Teranex Server is established, a user may send a special no-operation
command to check that the Teranex Server is still responding. In this case, a blank line is not
required following the command:
PING: ↵
If the Teranex Server is responding, it will respond with an ACK message as it does for any other
recognized command.
Closing Connection
To end a Telnet session in Mac, Windows or Linux, press and hold the Control (Ctrl) key and press
the ']' right bracket key, release the Control key, type quit and press the 'Enter' key. For example:
<CNTL>+]
quit ↵
Status Updates
When any parameter in the Teranex device is changed on the Teranex Server by any user, the
Teranex Server resends the applicable status block, containing only the items that have changed.
For example. if the output aspect ratio is changed to CentreCut, the following block will be sent:
VIDEO OUTPUT: ↵
Aspect ratio: CentreCut ↵
↵
Requesting a Status Dump
The user may request that the Teranex Server resend the complete state of any status block by
sending the header of the block, a LF, followed by a blank line. In the following example, the user
requests the Teranex Server resend the Video Output status:
