3. CAMERA OPERATION
3.1 Introduction
The MegaPlus camera, Model ES 4.0/E, does not have any manual controls on the camera itself.
Camera operation is accomplished by commands sent to the camera through a serial data link
from a personal computer (PC). The camera serial data link may be either RS232 or RS422. In
either case, the command syntax is the same.
The commands in this chapter are in the order that you would use to setup a camera for the first
time. A list of the camera functions, commands and appropriate page numbers follows:
NOTE: The commands can be entered in either upper or lower case.
NOTE: These same commands and their argument ranges are alphabetized and
summarized on page 3-12.

3.2 Serial Interface Protocol
The camera uses a full duplex UART type asynchronous system, using standard nonreturn-to-
zero (NRZ) format (one start bit, eight data bits, one stop bit, no parity). The baud rate is fixed at
9600. The character code is ASCII standard.
The character flow control protocol is XON/XOFF. XON is assigned DC1 (control-Q) and XOFF
is assigned DC3 (control-S). The receiver sends the XOFF character when it wants the sender to
pause in sending data and an XON character when it wants the sender to resume.
