Using Software Commands
INTRODUCTION
The KODAK Motion Corder Analyzer SR series all have an RS232C connection
on the rear panel of the Processor. If you connect one of your personal computer
COM ports to the RS232 connector you can control the Motion Corder from your
computer keyboard using the terminal program that comes with all versions of
Microsoft Windows.
There are eight commands, each command corresponding to a button on the
Processor's control panel. After you have setup and are running a terminal
program pressing the "r" on your computer's keyboard will have the same affect
as pressing the MENU/ENTER button on the Processor's control panel. The
parameters to use when configuring your terminal program follow.
RS232C SERIAL COMMUNICATIONS PROTOCOL
The Motion Corder is configured for eight data bits, two stop bits, and no parity.
The baud rate default is 4800 bps. Set flow control to none. The Motion Corder
responds to eight bit binary commands shown in this manual as two hexadecimal
characters.
The TX lines of your computer must be wired to the RX lines of the Motion
Corder and the TX lines of the Motion Corder must connect to the RX lines of
your computer. Check the documentation that came with your computer or I/O
card for the correct TX and RX pin numbers. A null modem cable connected
between a COM port on your personal computer and the Motion Corder will
accomplish this in most instances. The Motion Corder RS232C port uses a
25 pin D-subminiature connector with standard RS232C pinouts.
CONTROL CODES
The codes below are in hexadecimal and can be sent to the Motion Corder from a
program that you write. If you use a terminal program, the computer keyboard
letters indicated in the "Key" column will transmit the code to the Motion Corder.
