  • all of the documentation links are broken right now

  • Roving Networks list 3 variations - please confirm the model offered here is the RN-240M (RS232 with pins). Thx

  • I bought two of these to get a wireless link going. They work fine, but configuration was a headscratcher until I realized that there is no echo of the characters you type until you hit the Enter key.
    To make a DIY battery pack, get size H DC power plug from Radio Shack (274-1571) and a 9v battery snap (270-324) and some batteries. Works great!
