ARS USB Interface:......

The ARS-USB Rotator Interface allows computer controlled operation of an antenna rotator.
The interface is connected to the computer with just one USB cable (included). The drivers (included) simulate a virual serial port (COM port) which can be used with nearly any satellite tracking or contest software.
Due to the flexible design of the interface hardware, the ARS-USB can be used with nearly any rotator.
Rotators with and without brake are supported.

The protocol (the commands) used by the ARS-USB is the same as used by Yaesu, so any program supporting Yaesu rotators can be used with the ARS-USB.
Before operating the interface it must be calibrated to the rotator.

ARSVCOM software:.....

The included ARSVCOM software (for Windows) allows a computer control independently from any other satellite or contest program. This software is also used for calibration.
The ARSVCOM program can be used at the same time as another rotator control program.

The power supply of the interface is not done by USB, but requires an external 12VDC .200mA
A open ended DC cable is included, as well as an USB cable. CD ROM contains the english manual and the ARSVCOM software.
