13. SERIAL COMMUNICATIONS COMMANDS & PROTOCOL
PROGRAMMING
Communication protocol: 9600 Baud No Parity
8 Bits 1 Stop Bit
The following definitions are taken from the
"c"
source file which runs in the Pan
and Tilt Micro Controller. If you are writing an application to talk to the Pan and
Tilt, this file contains all the command definitions for communicating with the
units.
A host contmller, such as a PC or Control Panel, sends only two types of bytes to the pan
and tilt. This limited number of serial data transmissions has been developed to optimize
system performance over serial control lines. The "Header Byte" may be sent only once
followed by several "Function Data Bytes" or sent every time along with trailing data.
