After MMU setup and successful firmware flash, still seeing MMU N/A

Printer: Mk3S (upgraded from mk3 during MMU installation)
MMU: MMU2S

Printer firmware: prusa3d_fw_MK3S_3_7_2_2363.hex

MMU Firmware: prusa3d_fw_MMU2board_1_0_5.hex

I completed the MMU setup this afternoon and successfully flashed the printer, but under the Support menu on the LCD screen I still see MMU: N/A. The MMU has one green LED lit; the printer LCD displays MK3S on the info page. I've tried re-seating the MMU data cable but it hasn't helped. Any ideas?

Sorry, while doing a continuity check I reseated the data cable again and it worked. looks like user error!

Thanks for the tip. Same thing happened to me. The 2 data cables were not properly seated in the rambo box.

I took the board out of the box to check and properly connected them. I could not fully  see them while inside the box.
