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 3.29 below, which illustrates a “picture mute is off” reply from the projector:
Figure 3.29. ASCII as Non-Unicode and Unicode
NOTE: Use of unicode or non-unicode in messages is auto-detected from the TPC.
All available ASCII message codes, including those with multiple parameters, are
listed and explained in
Appendix B .
SETUP:

In the Admin:General menu, define which users (all, none or some) have remote
access rights.

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.

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 minutes.
SHUTDOWN:
You must close the application and shut down the socket properly
before shutting down the controller.
