Our plant utilizes 1540 Galil controllers, In the past we used WSDK32 for Trouble shooting and tuning. We recently purchased the latest version of Galil tools. We connect via a RS232 serial connection main front port. I am not able to make a connection with Galil tools yet the old version of WSDK32 still works fine. Is there possibly a firmware issue here with our controller and Galil tools.
