Help, Electronic pulse by a serial port?

[BluiSh]

Hello everybody!

I´m have already an aplicattion for the access of members in a gym, I need to open the entrance main door with my system but I need send an electronic pulse through the serial pulse to an electronic device, anyone knows if there is already a plug in for this activity? where can I get it?

I look already for for troi plug ins but I´m not sure if this can work and apart of that I think is too expensive for the only thing that I need it???

Please Help!!!

Thank you people

Hi BluiSh

What you need is a Mac FMP to external electronic connection as I understand.

So You need an external Micro controller which You can address by USB and e.g. applescript from FMP.

There are devices which use Rs 232 (serial) but than you need Troi plug in again ( The demo of the troi serial plug in works after the demo period but with a startup screen and delay )

You also would need some extra relais so You switch the door opener over a long cable switched by the relais at the micro controller.

A POS Cash Drawer Interface probably is very much the same what You need.

To give You some idea what I am talking please have a look at 2 sample “electronics” I have found

IO-Warrior - The "Universal" for USB http://www.codemercs.com/E_index.html
