system = SQ6 to AB168 through to a MEU ending at a single ME-1.
When I attempt to connect through the ABA168, I get no pass through however if I connect the MEU directly to the SQ6 I get connection lights on S link. I have tested with short CAT cables and all components work as required. I have replaced the 200’ board to stage CAT cable numerous times and recently purchased a CAT7E shielded, heavy duty cable and still receive NO signal to AB168. What am I doing Wrong ? Original installation company for our church system has ghosted us and refuses to return calls. I am at a loss for correction. Any suggestions?
