Section 1: Introduction
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 Messages .
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.
