I have a brand new MP40W on my tank hooked to the WXM module for Apex. No issues. To increase flow, I purchased a used MP40. It is a 2011 model (http://ecotechmarine.com/wp-content/uploads/2011/10/MP40-Manual.pdf).
When I try to hook to WXM, per the instructions here: http://www.neptunesystems.com/wp-content/uploads/2013/11/WXM_manual.pdf
It flashes blue/red, meaning it failed, instead of the blue/yellow.
It's about 4 feet from the module (other side of tank)
