Couple of basic questions about our aging, but reliable DS-2000 system. Finally installing 3.22.12 software. I believe it now has 3.14.xx. First of all, do you feel this is a wise move, or might I be inviting potential problems by disturbing our current status-quo? Secondly, I need some advice about making a connection between this older system and a new laptop. Access into the CPU is through a standard (NEC) 8-lead cable w/RJ45. The original specs called for this to terminate at the PC via a serial jack. Problem is, my new PC has USB, Ethernet & HDMI connections, but none of the older style. The Ethernet connection would appear to directly accept the RJ45 cable and I believe the wiring config is the same. Question is, can I "talk" to the DS system this way, or will I risk frying something? I'm certain you pros have already remedied this problem, so I'm asking for your help. Thanks in advance! Dan
