If you need this feature prior to the release of 11.4.0 then please email me. Note that you need an SCS Professional Plus or higher license to use Telnet Control Send cues.Several Sanyo Projectors support Telnet Control for features such as opening and closing the shutter, although in the Sanyo Telnet documentation these commands are actually defined as Video Mute Off (message C0E) and Video Mute On (message C0D). However, to control a Sanyo Projector by Telnet, a valid password must first be supplied in response to the message PASSWORD: which is sent by the projector when an application such as SCS establishes a Telnet connection. If the supplied password is correct (it may be blank) then the Sanyo Projector returns the message Hello. Only then will the projector accept commands such as C0E. If the supplied password is not correct then the projector immediately closes the Telnet connection.
If that weren't enough to contend with, the Telnet connection is timed out by the projector after 30 seconds of inactivity, ie if no Telnet command is received for 30 seconds then the projector closes the Telnet connection. SCS receives notification of the closing of the connection, so marks the connection internally as 'closed'. If SCS subsequently tries to send a Control Message to the projector, then because the connection is now closed SCS will re-establish the connection and wait for the 'Hello' message that indicates 'Device now ready to receive commands' and will then send that Control Send message. Tests have shown this operation to be very fast, so the projector should respond to Control Send commands 'immediately', whether or not the Telnet connection was open at the time.
Thank you, Mikk Mengel and Brian O'Connor, for your assistance in supplying information and testing the new feature.
