But why have the expense of a computer if you are going to use X10? They have a little timer that will do it ... http://www.x10.com/products/x10_mt10a.htm -----Original Message----- From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx]On Behalf Of Sullivan, Glenn Sent: Monday, October 28, 2002 11:31 AM To: 'windows2000@xxxxxxxxxxxxx' Subject: [windows2000] Re: Small voltage output from a computer? Does the existing system use a simple momentary switch to turn on all the buzzers? If so, buy an X10 relay module, attach it in parallel with the existing switch, and then buy an X10 transmitter for the PC. Then use any number of even packages to kick off the buzzer. My favorite is AutoM8it: http://www.AutoM8it.com. $40 at the most, especially since AutoM8it is free right now...

That would work on each individual PC system. The problem is that we have an existing buzzer system spreading over the whole factory activating about 50 buzzers, this lets 450 workers know when to go home and if their running late! What we were hoping to do was get a small output from the 'controlled time' PC that could activate the buzzers on time. Whilst looking on the net I found some PCI cards which would do a similar job but were very expensive, I was wondering if there was a cheaper alternative? Thanks for the help in advance!!

If not then you could always use either CTS or RTS and GND (on a COM port) hooked to a relay to up the voltage (plus you'll need to write the code to turn it on/off), or you could just hook up a sound card and speakers - sample the sound the bell makes then just play it back !!!!! jmeadows@xxxxxxxxxxxxxxxxx wrote: Hi all Is there anyway to get a small voltage output from a computer? We are wanting a PC to activate our works 'buzzer' when it is time to start and finish work. The system we have in place at the moment can't synchronize it's time with our PC's. We are wanting a PC to activate the buzzer when the time is right, this requires a small voltage output. I think I read somewhere that COM1 will give a voltage output but I'm not too sure how to activate it? Any help would be much appreciated.
