A bureau of the original network has two MCU, but no cascade, independent of each other. Council now wants two MCU cascaded to mutual control. Determined on the lower level and cascaded MCU, MCU has been found to lower membership, but switching image, no display, two MCU can not see each image.

Has membership, can not see images. There are two possibilities:
1, the membership displayed incorrectly, fake membership.
2, has membership, but the ability does not match, the result can not see images.
View diagnostic interface port has been found to synchronize, in order to further determine whether the port is true synchronization, respectively, in two MCU is done from the ring, the synchronization is no problem, you can exclude the first possibility; checking two MCU's ability to set up and found two the ability to set the MCU has many inconsistencies, the ability to modify the settings, re-admission, you can see the image. Problem solved!
Two MCU ability we're set to inconsistent, causing capacity to not match, so no mutual control.
