Most TPC projector functions can be controlled remotely, typically at a controller,
via simple bi-directional ASCII messaging on an Ethernet communication link.
WHAT SETUP IS NEEDED?
controller, you must open an Ethernet socket between your controller and the valid
TPC address. See complete instructions in Setup and Shutdown later in this section.
Note that only one "physical" connection is permitted at any given time, and access
to remote functions may be limited by the installer. Do not use an RS-232 (serial)
link.
All "remote control" information passes in and out of the TPC as simple messages
consisting of command code and any data related to it. Such messages can be a
command to set a projector parameter at a specific level, such as changing to a certain
channel. Or the controller can request information, such as what channel is currently
in use—the projector then returns the data in a reply message. Regardless of message
type or origin, all messages use the same basic format and code as shown in Figure
3.28. Where applicable, a message can expand to include additional parameters of
related data.
