Attaching A Video Input; No Circuitry Protection - Matrox Meteor Installation And Hardware Reference

Attaching a video input

Attaching a video input
Matrox Meteor and Matrox Meteor/RGB have three connectors
on their brackets:
Use the PC-OCABLE-4 or PC-OCABLE-10 cable when
connecting to the DB-9 input connector. These cables work with
composite or RGB input.
To connect to the S-VHS (for Y/C or trigger input) or phono input
(for single composite input), use standard video cables available
from local electronic stores.

No circuitry protection

Warning
The trigger signal on Matrox Meteor/RGB is not buffered or
conditioned. The circuits on Meteor/RGB are sensitive to static
electricity and surges. Please be careful about what is hooked
to the trigger input of the board since there is no circuitry
protection.
There are several ways to provide circuitry protection. For
example, you can add an opto coupler between your TTL trigger
source and Matrox Meteor/RGB trigger input. This would help
isolate the rest of the circuitry from any potential surges.
