  • Overview

iOptron RS232-RJ9 Cable

what our customer say this product:

  1. Shawn R. Verified Buyer – 29 December 2018

    When you paid this with the USB to serial adapter, you can easily drive the mount from your laptop. Works like a charm … MUCH easier than using the hand controller as you use the ioptron commander GUI on the laptop which isn’t as sensitive to the cold as the 8408 controller
