Any Ponemah 5.x version before v5.20-SP6 and any Ponemah 6.x version before v6.10 has an incompatibility with CLC firmware v0.1.25 that will cause a crash. This will necessarily include any third-parties that have implemented early versions of DSI-LINK as well.
The problem is that between CLC firmware v0.1.24 and v0.1.25, the formatting of the current frequency string a CLC reports changed. For example “F1-A1” (firmware < v0.1.25) became “F1_A1” (firmware v0.1.25)
Although this does not crash newer versions of DACSS (greater than or equal to 1.4) it does cause the configuration wizard to not correctly report when other CLCs are on the same frequency.
This is corrected in CLC firmware v0.1.26.
