I did not make
any circuit this weeks. I just read this week's lab assginment and tried
to follow what they are and what I am able to use for the future project.
Here is the source
I found.
RS232
Interface
between a terminal (DTE : Data Terminal Equipment) to a modem (DCE :
Data Communications Equipment) Employing Serial Binary Data Interchange
(for the transfer of serial data) .

LANC
LANC was
developed by Sony, but Sony has licensed LANC to other manufactures
of 8mm and Hi8 camcorders. LANC support is found on all Sony camcorders
and most 8mm or Hi8 camcorders from other manufacturers. Sony also supports
LANC on its 8mm, Hi8, DV and top of the line S-VHS VCRs.
LANC connectors are usually 1/8" mini plugs - about the size of
a Walkman headphone. Some devices use a circular 5-pin DIN jack.
LANC sockets are normally labeled LANC, Control-L, Remote, or designated
with a special LANC symbol that resembles an "L" inscribed
in a circle. To determine whether or not your camcorder or VCR is LANC
compatible, refer to the lists below, check the camcorder or VCRs users
manual, ask your dealer, or contact the manufacturer directly.

LANC CONNECTOR RESEARCH
What?
The Lanc connector appears on Sony DV equipment. It is a means to serially
control the DV device. A 2.5 mm lanc connector cable attaches to the
DV device. The other end of the cable needs to be the typical serial
connection, as we have been using in class. These would be the RS-232
or the RS-422 connectors.
Why?
The Lanc connector can be used in editing and in remote controlling
the DV device. A referenced web page on the Lanc described it as being
possible to control practically all camera functions via the lanc connector
How?
The baudrate is 9600.
It is a two way open collector serial connection. An open collector
is defined as normally set to the high, or 5v. When sending commands,
the connection is pulled low, or to 0v. The data stream of information
is 8 bytes per frame with a break in between the frames. The serial
connection must sync to the device to display the signal. I think this
involves adjusting the parameter mask recognized by:

Subject: Ctrl-L or LANC on VCRs
Does anyone have experience of controlling Sony domestic VCRs through
the LANC (Ctrl-L/S) port, as the basis of a simple video-based motion
analysis
system? Or does anyone have a copy of the Ctrl-L specification they
could
lend? Or are there any commercial boxes which will convert AIO or DIO
lines from a PC into LANC?
The plan is to use digital IO from a PC to control frame-stepping and
to
read the RCTC signals. Any suggestions will be very welcome.
