Looking for a simple non-programmable message display

Well I would say that 2 lines of 16 characters each would be about the minimum. But ideally I'd like to pack as many lines and characters as could fit in, say, the space required for a 4" HMI.

The code might get ugly, but it's certainly doable.

Surely this is the winner. Looks like you can just plug it in and it displays whatever you put in the holding registers.

Looking at the options on a UMD* you could get a HMI for a fraction of the cost with much higher functionality.

*Which confused me until I clicked the link, I was wonder what application a Universal Media Disc had on this forum.

Yes, this is the closest thing I've seen to what I need. Thanks drbitboy!

If your looking for a larger alpha numeric display.

larger is more expensive

Silicon Craft has several options. Easy to set baud rate and other info for the protocol. ASCII, RS232/485, Modbus are all options. I have used many of the 4 digit 7 segment LED for a machine that I upgraded. (The original used a 2 digit 7 segment LED that flashed a 4 digit code. Now there is no flashing just the code.) Would have used the 4 or 2 line LCD's but I tried to keep it as close to same as the original for the operators. A

Schneider had XBT N200 and N400 LCD series, but it is allready obsolute. It was modbus serial.
