[amsat-bb] Question regarding Yaesu G-5500 AZ/EL Rotor

[Bernie and Cheryl]

Dear Folks:

I am looking into getting a satellite tracker box to connect my computer 
to my G-5500 rotor so I don't have to manually track satellites any 
more.  I get the impression that I would hook the tracker box into the 
back of the rotor control box (where the 8 pin DIN female connector 
is).  However, the manual for the 5500 states as follows:  "If the 
optional GS-232 Computer Control Interfaces Unit is installed, the 
RS-232C cable from the computer routes through this grommet ..."

This implies that I need to buy something else from Yaesu and install it 
in the control box in order to utilize a tracker box. But, I've never 
heard of anyone doing that.  So, has someone out there hooked up a 5500, 
and did you have to buy an optional unit for the Yaesu rotor control box?

Thanks for your help.  73 de Bernie, KF0QS
