this analouge receiver,on the picture,i also have,it comes,from kathrein,but the remote is also missing..!

on the back side
this heavey box has a lot of connections for e.g
lnb in ,to rvcr to rvr from lnb

polarizer gain controll ,normal m1 m2 etc

weight around 5 kg!
now i dont know ,how i can connect this device,and what analouge receiver is needed?
is this a montery on the picture?
i dont know this type!
the problem,i have no remote for!
when i look on Ebay usa,the all sold without remote,maybe some one from amaerica ,can explain me,how i connect,and can use this device,maybe it is usless now ,i dont know!
this looks like a profesional system,that used maybe 15 years ago,but without remote,maybe i can not use it..
or a master analouge receiver,controlls it,like a slave box?
there are so many types of drake earthstations on Ebay usa,but what is the difrent,in each modell?
maybe a usa member knows it
