Just installed pitch and roll servos, AP74, remote compass, and EFIS in a Glasair III. The EFIS and remote compass were already installed and operating for the last 3 years with no problems.
During configuration found the following:
The first config try found the efis, remote compass, ap74 and one servo. Double checked and ohms all leads to not found servo. moved inop servo to good servo connection and still no connectivity. Moved inop servo to previous connection and retried to config. Now neither servo will connect. I used the cabling from the STEC 30. Wonder if the non twisted pair cable is causing the connectivity issue with the servos. We used twisted pair between the EFIS and the AP74. Need some input.
