[amsat-bb] LVB Tracker & G-5500 Rotator

Hi All,

I am having problems trying to use the LVB Tracker/G5500 on the Serial 
Port. My box will not communicate. Mike Young sent me another box with 
the MAX232 chip and I am not able to communicate with it either. I can 
control the G5500 via the LVB faceplate.

I am using COM Port 1, 9600, 8-N-1 None and CAN communicate with 
hyperterminal with a loopback plug. When it is plugged to the LVB box I 
am NOT able to communicate via hyperterminal or SatPC32. The SDX Server 
is set correctly to COM1/9600, has been saved and SatPC32 recycled. 
Still no go.

My original box, when the USB chip is removed and a MAX232 chip 
installed appears to communicate with the G5500, but when the G5500 is 
powered off, both meters on the G5500 peg to the max. Very strange. 
Still not control via Serial port.

Anyone have any ideas? Mike & I are stumped on this one.
