I included controlthink as a controller device in my network (shows up as a RS232 device). Anyway, now when I try and update my routes from the RZCPG hand controller, it stops at the controlthink device as indicates "not found". I can "update controller" fine using the RZCPG with controlthink as a device. I have controlthink running when I try and update the routes from the handheld unit. Any help as I've added some new modules and I don't think the programmer is finishing the route routing because it gets stuck at the controlthink contoller unit. Thanks. SJ
