This is a special version based on the ARS-USB that was re-designed to be used as a rotor controller or replacement for a Yaesu Control Unit (or similar rotators) that operates 24Vdc

The ARS-USB_Yaesu is a direct replacement control box for Yaesu rotators (G800, G1000, G2800, G450ADC/G450CDC) 

It includes the same features as the standard ARS-USB adding some extra as:

  • Simple and easy calibration at any rotor position in few steps.
  • Soft start and stop via a PWM. It allows to have a soft starting/stopping ramp.
  • It detects if the potentiometer is out of range and will prevent any accidental problem with the antenna coax. Any problem with the potentiometer or cables are detected inmediately
  • If the motor is jammed by any reason, an alarm will be displayed and the appointment will stop. The user will be noticed.

All those watch-dog systems (and some more options) will prevent to generate a problem if the potentiometer is damaged by any cause (any wire broken, moisture, a wrong cable connection, etc).  

This model include a 24Vdc DC-DC module which is necessary for Yaesu motors (G800, G1000, G2800 or new G450DC) and It can operate on emergency power and battery (12Vdc)

SKU: ARS-USB_YAESU Category: Tags: , , ,


The ARS-USB_YAESU is a special version based on the ARS-USB that can be used as a replacement or controller for any rotor that operates 24Vdc. Some Yaesu models suported are:

  • G800S, G800SA, G800DXA, G800SDX
  • G1000A, G1000SA, G1000S, G1000DXA, G1000SDX, G1000DXC
  • G2800DXA, G2800DXC
  • or the new G450ADC

But it can be used with any motor that works in DC and uses a potentiometer (for instance Emotator 1200). It includes a 5 pin connector for simple wiring with any Yaesu motor.

The ARS-USB_YAESU  can be connected to the computer via USB and it’s detected as a serial port, so any program will be able to control it via this serial port. Moreover it emulates a Yaesu GS232A interface; this fact has the advantage that any program that supports a GS232A will support directly the ARS-USB_YAESU.

A program to guide during the setup and calibration is included: ARSVCOM (ARSConf).The calibration of a unit is very simple and includes a step by step guide. Also it allows controlling the rotor with a graphical and friendly user interface. It’s a nice option when you want to control the antenna local or remotely via Internet.

A tool for upgrade the firmware of the ARS-USB is included: Teleloader. With this software, you will upload new releases of the ARS-USB_Yaesu firmware.

There is an optional pigtail cable that can be ordered to mate with existing Yaesu cable. Yaesu (white plastic) 6 pin connector for Yaesu (A, SA and DXA controllers)
There is also an optional PCB (POT2-3) that will adjust the input level of rotors that use only 2 wires (current) to the voltage input required by the ARS-USB. This is the case of the G450ADC.
