I've been using the tester successfully in wired and wireless mode for over a month now. The other day when using it to turn on all my LE's using dimmer value 255 and channels set to ALL, the LE's would respond and then lock up within 30 sec to 1 min. I tried changing the batteries and had the same problem. It was not happening a few days ago. To rule out problems with the LE's and EX/RXs, I took a TX/RX configured in TX mode and connected the tester's wired output and reset all the LE's and it worked fine for several hours without locking up the LE's. Any ideas on where I can start to troubleshoot the tester?
Thanks,
Josh
