I'm trying to install DSS console in a KX-NS700XE system. The DSS i'm currently using is KX-DT590X which is compatible with KX-NS700XE. I've tried plugged to a regular port on a DLC16 card using the cord it came with and the DSS doesn't boot up / show any sign of connection between the DSS and PDX. I've even tried to select the DSS console setting through Web Maintenance Console but it gives me an error "E00030A operation cancelled. Please set appropriate settings". Is there any ways to solve this problem?
