Hello Kristen, My name is Ron, I'm life in Kiel in Germany and I'm a owner of a ISC Pathfinder. It's very complicated to contact the ISC Headquarter to get any information. Naturally...I have a manual....but there I can read, that's all the same where I connect the plugs for Handset Shearwater ....Primary or HUD. It's not so. The ISCAN is devided in primary and secondary network. They are not really connected..... if you set the setpoint on first plug with the Handset ....you need it at the second to.... Do you have any other information...yailbreak...content...about the ISCAN..... Thanks in advance... Ron
