 I would like to use an Arduino UNO to read an input from a Fluke device. This device only has RS232 capabilities. From reading the ACC4LV manual i could update the IDE library with a RS 232  shield's library and then modify it to run with LV. Is that roughly accurate?

Being that I have minimal C- coding experience I need to find a different solution. I could just run a standard LV program and use a serial converter to talk to the Fluke device. But i would rather utilize the UNO since I am using it for part of the test already.

Is there any other options to consider? Or would the modification to the 232 shield code be fairly minimal and maybe I could stumble through it? 

 

Thanks

Yes, u have to connect ur UNO to fluke on pin no. 0 & 1 and make ground common of UNO but make sure u put TTL to RS 232 converter in between. 

Programming in LV will be different as you have to use only complier specific VI's there, but make sure u take care of memory management as smaller boards has smaller memory so be cautious.

Rest thumbs up for your trails.

Do update later ur experience.

Thanks, Diwan

I will give this a try and post my experience.

As Lovediwan was saying all you need to do is use a RS232 to TTL converter IC like a MAX232 and connect it to pins 0 and 1 on the Arduino (Rx  and Tx)

Then communicating with it would be just like communicating with any other serial device using an Arduino.

Thanks for the reply's. I ended up writing a driver in LV 2015 for the Fluke 1524 meter. There was none available for it.Then had to make a cable to connect to the 232/ USB converterand connected the the PC. Its a relatively new Reference thermometer. I then wrote a program to write the sensor data to an ini file and then reading the file with a already developed data logging program. I want to do the least amount of data compiling after the test. 

I would like to try some 232 comms with Arduino still. I'll probably have another application for it in the future.
