You can get USB to RS232 cables for very little, so any laptop should work.
And how cool would you look carrying your laptop like an attache case, with dongles and wires hanging off it? No thank you. If I need to interface with cold war era serial hardware, this is the way I'm going to do it.
You do realise there is equipment being manufactured today that uses RS232?
Yes. Cold war era tech being manufactured today. You do realize there are plows being manufactured today that are intended to be drawn by oxen?
It was a tongue in cheek comment and you've already displayed elsewhere in the thread how much you know about RS232 but you couldn't let it slide.
We have brand new machines that use RS232 and RS485. We just did some configurating on one of them last week.
So do some fire panels, come to think of it. They use RS232 for programming, and either RS232 or RS485 for communication between modules.
Yep. Coincidentally, part of that job involved a fire panel.
It falls under the KISS principal - and if it ain't broke, why fix it?
Oh, definitely. There's a lot of products in the fire industry that haven't fundamentally changed since the 80s or 90s, maybe a few tweaks.
People have reported those not working very well with STAR / DAS I believe. You can usually buy the kit with a laptop included, I just figured I'd wanna try if it runs on something made less than 23 years ago.
