I am totally new to mikrotik and sr9’s.I am only doing this to get high speed back to my house (from my friends house 5 Miles away) without the high cost and latency problems with Hughesnet.I have connected with avalan transparent bridge (plug and play) 900 mhz radios until they died.. What i have is 
1) Rb133c , (1) Rb 112 , AND (2) SR9 cards. I would be very thankfull if somone that knows these boards could tell me the settings to where they connect and communicate . I have tried some settings that I have foiund on this site , but the “units” will find each other but wont “connect”.So please if you can share some info and guidance I would be appreciative ..

Thank you for the reply ,I tried to do it in “win box” but no luck.I may be looking at the wrong pic or something, its on my behalf Im sure .I think im going to try it in “console” It may work better I hope .I will see if it works better for me.Thank you again.
