inexpensive operator interface (mini-terminal)

Jul 07, 2005 7 Replies

I'm trying to locate something for a customer to connect to one of our SBC's.



Why can't I find an inexpensive operator interface? You know, something like a mini-terminal with RS-232.



A squared away design where you can cut out a rectangiular hole and drill 4 mounting holes and put it on a panel inside a NEMA box or something. Not pretty, but inexpensive and useful.



(Not some PIC project, I have found most of them. I have also found all the so called inexpensive PLC oriented ones for $500. Not those either.)

Sorry to followup my own post, but I forgot to clarify: I haven't used any of these, and have no connection whatever with either company. They just look like interesting parts.

How about a PDA? I used to use a Newton for this sort of thing, which had RS232 built in, but you can probably get a palm pilot for $100, write or contract the interface program, and mount it without too much trouble. This way, you could have a nice, customized touch pad display for your widget.

Actually, this isn't a bad product idea, for those who have the channel to get it out there. Licensing the guts and OS from palm or whomever is probably not a big deal, since they would make most of the money.

Not enough demand, off the shelf PDA's/small laptops could be adapted to do what you want.

The local home improvement big box has a "inventory control" system that uses a Palm Pilot for the input device. It is mounted inside the enclosure, but if you look, just right, you can see the unit. I have seen ads in one of the trades where some Asian company has a Palm Pilot rip off that is basically a PDA with none of the OS goodies installed, along with some development tools to get it going, if I stumble across the ad again I'll post a link here.

Which PDAs have still a serial interface?

Palm "Zire" don't:

"Please note that Palm Zire Handhelds DO NOT support serial (cabled) connections to the computer."

What a pity.

I have used Two Technologies a few years back and remember the smaller units to be reasonable.
