Ok great, 38400 did the trick! Thanks

Hi, The default port settings for Modbus are 38400,8,N,1. You either use the same on your scanner or change it using the command line interface (check the online help for details).

Thank you, Alex.Just for clarification — does "Calibrate input channel, the calibration must be done in 2 points" mean that I should connect a known voltage (for example, 5 V) to di...

Hello Alex,Thank you for the information. I tried the firmware update, but it looks the same as before.Board firmware version is 1.4. Without input: With 5V input: After calibration for 5V...

Hi, The latest firmware version is 1.4. Calibration must be done at two points to be complete. The two points must be as close as possible to the two ends of the measurement scale for good results.

Hi Jan, We recently discovered that we have a bug in the firmware, and we took care of it. Please update the card firmware, instructions here. Anyway, for good results, you need to calibrate the c...

Thanks for your time James

Hi, IGND is pin 1, and OUT is pin 2. You can vary the schematics as long as current flows from OUT (pin2) to IGND(pin 1).

Thanks.

You are right, the two extra pins are for RGB backlight type display. You can ignore these two pins for the monochrome version. As far as the buy options of the RGB display are limited, the Adafrui...

I have a couple of the SMS display adapter cards for RasPi and am mating these with 2004A display cards. that are said by mfgr to be RasPi compatible. The SMS card has an 18 pin interface, but the ...

My power supply connector on the board was not snapped in all the way for the 24VAC.

Well my Triacs are back to misbehaving again. The triac will close, when it is commanded to, then it will not stay closed. The relay that it is controlling will drop out, then a few seconds later...

I am glad you managed to communicate with all the cards. I did not realise you had no delay between reads. Sorry, the port number does not match the serial port names. I guess you found the corresp...
