Yes, this is correct. �The only way that you will be able to control the RadioRa2 is through a MSC400.
While serial control of RA2 is preferred and allows for much more, it isn't the only option.

It may be less expensive to purchase another keypad and install it near your equipment. Program the desired scenes or loads and run an IR cable from the MRF350 to the IR on the keypad.
Regarding a repeater, if you chose to upgrade to MSC400 for serial control, is it possible to simply relocate your main repeater to the location of the MSC400?
