I know nothing about this equipment so please don't ask!
See this Zetron Introductory Information page for background and other useful information.
Default passwords - for those units that need them - can usually be found in the manuals.

The cable that plugs into the 38A is part number 709-7112 (and the price in fall 2006 was US$35). This is the generic cable with flying leads (as opposed to one that has a connector that is designed to plug into some other manufacturer's equipment).
BTW the differences between a 38 and a 38A are changes to both firmware and circuitry. They are similar in function and name but internally they are essentially different products. It's not really practical to attempt a field upgrade.
Anybody have the 38A Brochure or Repair Manual?

Anybody have the Instruction Manual, Repair Manual or Schematic?
Zetron, Simplexor, Worldpatch, Microconnect, Repeaterman, Europatch, DeadBolt and probably a few other terms are either service marks, trademarks, or some other legal mark and no infringement is intended. If Zetron had these files on their public web site we wouldn't need to.
