Why do we need another rotator interface?
Hardware PC interfaces have changed
but rotator interfaces haven’t
Kansas City Tracker – ISA slot
Many others use COM ports or LPT ports
USB is a new standard
TCP/IP is now a de facto standard

The ISA Slot/COM/LPT port problem
ISA slots are non-existent in new PCs
COM
(RS-232) ports are becoming less common in new equipment, laptops in particular
LPT ports also less common, and also difficult to program control signals from applications under newer OS’s
Lack of interrupts on PCs!

USB – The ‘new’ standard
USB is now very common
Traditionally very difficult
to develop USB drivers, so only economically viable for large volumes
Each OS has a completely different driver model
