Hi, I am attempting to connect this device to my computer via RS232.

I am debating the simplest way of going about this and was inquiring if my Uno R3 could come into use, turning the analog symbols of 0-5 Vdc and 4-20 mA from the GFM into an output in serial port over a COM port. I have an RS232 to USB and I am just now tasked with completing this.
