EA4TX – ARS-USB Manual – June. 2024 Page 2
Introduction
Thank you for purchasing the ARS-USB Product.
Presently, the ARS provides the most powerful highest performance and lowest cost
universal rotor interface available anywhere in the world. It can be connected into any
rotor providing 10 bits ADC resolution (2 ^ 10 = 1024 states).
It can work with any “azimuth rotor” or “azimuth & elevation rotor” and a large list of
control and tracking programs are also supported.
Moreover it will convert your rotor into the latest technology automated rotor tracking
system available.
It’s very important that you read this manual carefully. Failure to understand
the contents of the manual could lead to damaging the rotor or the ARS-USB
circuit board through incorrect wiring. Remember that the time you spend
reading the manual and understanding how the system works and how the
ARS-USB board will interface with your rotor could save you time and money
by avoiding an incorrect installation. If any questions occur when reading the
manual, please contact us. Our goal is to provide you will a state of the art
antenna tracking system.
The ARS System has been developed to operate with most rotators available at the
market. If you don't find your rotor mentioned in the Quick Start Guide, again you
should contact us. We will provide assistance to help you successfully connect your
rotor to the ARS-USB circuit board. It is certain that no changes will be required in
the ARS-USB circuit design.
This board is the product of design evolution of previous RCI-SE circuits beginning in
2002 and restyled again in 2011.
The board is not powered by the USB port from your computer. It requires a 12-
14Vdc from a power supply.
When connected to the computer and a 12-14 VDC regulated power supply, and the
proper driver installed (see note), a virtual COM Port will be added to your computer.
The ARS-USB firmware will emulate a Yaesu GS232A interface. Any 3
rd
party
program that supports a Yaesu rotator will be able to control the board.
Additionally, you may use a supplied program called ARSVCOM that will control the
board and allow adjustment and configuration of the ARS-USB product in an
attractive package.
Note: Since Windows 10 and 11, the driver is included by the operating system, so no additional driver
is required to be installed.
