A switch. I have 8 units that are doing this (all set to different static IP addresses), and I have talked to tech support who doesn’t seem to be having the same problem with their unit. So I am shipping one back to Blackmagic for evaluation/repair. I have made sure that the static IP set on the unit and my PC have the same domain. I am not successful with pinging the Hyperdeck or telnet (with HyperTerminal) on port 9993 or 23.
Hyperdeck Studio Firmware 3.8
Windows Pro 7 SP1 64-bit
Intel i5 2.40 GHz, 8 Gb RAM, 500 Gb Hard Drive
