As noted in the [url=http://www.cbusforums.com/forums/showthread.php?t=9994]other thread[/url] on here, the Wiser 1 has an undocumented 25 measurement channel limit even though PICED allows 100. The Wiser 1 was running the latest firmware and PICED is the latest as well. I've not tested it on the Wiser 2 or on a CTC but the PICED help file lists them also supporting 100 measurement channels. The spectrum touchscreen, B&W touchscreen and PAC are all listed as having a maximum of 25. There is a footnote mentioning that analogue measurement channels, pulse power meters and total power meters have separate limits but doesn't mention what they are. The measurement channels I was using were all analogue ones. Apologies for the crossposting but this limitation caused some issues on one of my sites until I worked out what was going on and found that old post on here.
