3.6.4 What is Actually Sent in a Message?

Although you will send and read all messages as strings of ASCII characters, the actual message travels as a
sequence of bytes. Each character in a unicode message requires 2 bytes, whereas the non-unicode requires
only 1 byte. See example in Figure 3-41, which illustrates a "picture mute is off" reply from the projector:
NOTE: Use of unicode or non-unicode in messages is auto-detected from the TPC.

3.6.5 Available ASCII Codes

All available ASCII message codes, including those with multiple parameters, are listed and explained in
Appendix B: ASCII

3.6.6 Setup and Shutdown

SETUP
1. In the Admin: General menu, define which users (all, none or some) have remote access rights.
2. Open an Ethernet socket to the TPC address (socket = 5000). By default, the TPC address is
192.168.206.110. If you have additional TPCs, the installer should have defined their addresses as
192.168.206.111, 192.168.206.112, and so on, or used other addresses that are valid for your site.
3. Communication protocol should now be established (and can be confirmed with a PNG? if desired).
NOTE: The socket will automatically close after 15 minutes of inactivity. Program your controller to send
a PNG? message every 5-10 minutes to maintain communication and keep the socket functioning.
Important! To prevent shutdown of the socket, program the controller to send a PNG? every 5-10 min-
utes.
SHUTDOWN
Warning! You must close the application and shut down the socket properly before shutting down the control-
ler.
