Thanks to everybody for all the help on this.
Lot¡¯s of interesting tests. It¡¯s clear that programming isn¡¯t always reliable, but there didn¡¯t seem to be a case where Paged mode worked and Direct Byte did not work. So that makes the case easy.
Starting with the next test releases, Digitrax programming will first try Direct Byte mode.
Thanks again.

I have a DCS51 but had a DCS50 previously. I could only get it to read an older QSI decoder in Direct Mode with a PR3.

But there¡¯s still the open question as to whether (some) DCS100, DCS200 and DCS50 command stations have trouble reading and/or writing in Direct Byte mode some or all decoders. QSI decoders were mentioned several times in that context.
Is there anybody out there with one of those command stations and QSI decoders who could test reading and writing in Paged Mode and Direct Byte Mode?

Bob,
I tried QSI V7 and V9 decoders with both a PR4 and with a DCS100's programming outputs.
-The PR4 using Paged mode correctly read CV's 1 and 66 on both the V7 and V9 decoders, but corrupted CV29 (wrote 255 to it) on both of them. Writing 34 back to CV29 worked okay (verified by reading in Direct).
-The PR4 using Direct mode correctly read CV's 1, 34, and 66 on both the V7 and V9 decoders. Writing to these CV's worked okay.
-The DCS100 using Paged mode correctly read CV's 1 and 34 on the V7 decoder, but repeated read attempts all returned the same incorrect value for CV66. However, it did NOT corrupt this CV as a subsequent read with Direct returned the correct value. I did not attempt any writes with this combination.
-The DCS100 using Direct mode correctly read CV's 1, 34, and 66 on the V7 decoder. I did not attempt any writes with this combination.
-The DCS100 would not read the V9 decoder in either Paged or Direct mode. I did not attempt any writes with this combination.
HTH,
