I am having a problem with scan time. i have a chart for each serial port to scan head. all six charts need to run at the same time and ars triggered by the same sensor. it works but i need it faster and it some times looses a port and it gets hung up. I am running at 115.2k. I think with my other charts two others it is causing me trouble. does anyone know of a better way to do this maybe a script or one chart or something. under the gun and I am desprate    Report

If so, have in mind that each call to StartChart or CallChart will use about 100 milliseconds. I would try having the 6 charts running in parallel all the time (cycling). Of course, also consider the possibility of merging all serial communications into a single chart, even though that complicates developement and maintenance. If I'm far from reality, please give more details Good luck    Report

Did I read correct that the scanners are no longer slaved together, that they now communicate to indivual serial ports? If so, what was the reason for that?    Report
