AC Control Via Serial Port


Thread Starter

Rick Saavedra

I need information on building an adapter that will be controlled via the serial port. It will be used to be able to turn on/off a camera attached to it. Does anyone have any ideas where I can get info or has anyone done this already. Thansk in advance. Rick
Hi Rick,
Can you be more specific?, as to what exactly you want in terms of power required by the switching circuitary.

I think that using a miniature relay can help you. It can be signaled using the com port.

If you need power to drive the relay, an externally powered line driver can help.
