I pulled tb0123-2007 D Channel Diagnostic Procedure off the Tadiran website. But all it gives is the hex on Layer 2. Where can I find Layer 3.

Next question to get me in deeper trouble. What are the rest of the dipswitches on the MCP2?

If this needs to be over in the installers forum. Let me know.

Never blame on malice, what can be adequately attributed to STUPIDITY!!
