Morningstar RM-1 arrived early and in perfect condition. It works as described in manuals RM-1 MS-ZMAN-RM01-A and SSMPPT MS-001178 v3.7, Counter Board SSMPPT.APP MS-ZMAN-RM03-B and SSMPPT Error and Alarm Codes. No surprises and it's more convenient for me than using MSView to query for the same options.
