AD200 not displaying TCM properly

I have a new AD200 with the Pentax R2Pro trigger. I have the trigger set up for the AD200. When I shoot in TTL, I should get the equivalent manual reading when I push the TCM button. Instead I get 1/1 full power setting. My firmware is 2.1 on the AD200. There is a firmware upgrade of 2.2 but I am waiting for a USB to USB male cable to come in from Amazon. Will this upgrade solve my problem? Also, most of the time, the TTL exposure is about 3 stops too dark. I have to do a +3 on the setting. Will the upgrade fix this?

Glad to report that version 2.2 on the AD200 will incorporate the TCM function and will fix the severe underexposure problem in TTL. Hope this helps later Pentax users.

Nice to hear. BTW, just to double-check, when you say you have the trigger set up for the AD200, do you mean you have the C.Fn TCM set to 200j, so that the Xpro-P knows an AD200 is the light being used for TCM?
