Posted 4 Nov 2016 I'm not sure of a solution at the moment but if you want to try Com A, set Com B to 'None'. Then you should be able to set Com A to Host Link. 1 person likes this Share this post Link to post Share on other sites
Posted 4 Nov 2016 Attached is the correct pin out for the cable. Make sure the CJ1M Serial Port is set for Host Link and the correct communication parameters. Hope this will help. NT31C-CN320-EU.pdf 1 person likes this Share this post Link to post Share on other sites

Posted 5 Nov 2016 What is the PT Control Area set to? This area controls what screen you are on. 1 person likes this Share this post Link to post Share on other sites
