Below are the differences between the MA0185000 and the MA0185100 including revision:
MA-0185-000
A Product introduction. No revision marking on the tap label.
B Redesign to improve return loss.
C Redesign to improve the network 75Ω impedance match. This is the lowest recommended revision that should be used.
Although it was allowed to mix the –000 revision B and C taps, performance was limited to that allowed by the older B version which did cause communication problems.
The –000 part number was obsoleted at this revision.
MA-0185-100
A No design change. Supercedes –000 Model. Logo and color change only. –100 suffix required for documentation purposes.
B No design change. Removed “F” connectors from the shipping bag.
C No design change. Internal documentation issue that standardized many product descriptions. No stock purge required.
