What is the maximum device capacity on the NFS2-640 in FlashScan mode vs. CLIP mode, and can you mix protocols on the same SLC loop?

In FlashScan mode, the NFS2-640 supports 318 devices per loop, consisting of 159 detectors and 159 modules (Page 8) [1].

The total system capacity is 636 points across two loops (Page 1) [1].

In CLIP mode, input modules must be set to address 19 or lower, though the manual states there are "no limits" to detectors or output modules (Page 47) [1].

I could not find information in the manuals regarding whether protocols can be mixed on the same SLC loop, though the documentation specifies that loops are "configured to run" in CLIP mode (Page 47) [1].
