I have a customer that wants to install an old 8x24 DR5 from storage. When I hook it up it works fine but will not detect the 0x16 attached to it. It has the 2 port copper expansion module and a 12x0 line module. I've tried reversing the ports on the expansion module. Tried swapping the expansion DS30 cables, I have even tried a different 0x16 module. Will the non DS software accept a 0x16?
