Manufacturer: Research Concepts Model#: RC2000A Nomen: Dual Axis Antenna Controller Condition: Used Return Policy: AS-IS The RC2000A antenna controller is designed to control a dual axis antenna with 36 volt actuators and pulse type position sense feedback. The RC2000A was designed with the requirements of the commercial user of satellite downlink services in mind. Features The controller utilizes a solid state drive system capable of providing 8 amps to the antenna actuators. The drive system has built in over current sensing with mechanical relay backup to disconnect the drive from the actuators in the event of a fault The controller can provide polarization control via a Chaparral type polarotor. The AutoPol feature allows the controller's polarization output to be slaved to a digital input or contact closure obtained from a satellite receiver The controller also has an internal expansion port that can accept optional daughter boards. Two daughter boards are available which can provide polarization control, designated RC2KPOL and RC2KHPP. The RC2KPOL is designed for use with the Seavey model ESR-124D motorized feed with potentiometer feedback. The Seavey feed requires 24 volts at 500 milliamps. The RC2KHPP option is designed for motorized feeds with potentiometer feedback which require 5 to 40 volts DC at currents up to 3 amps. Version 1.50 of the software supports the RC2KPOL option. Version 1.51 supports the RC2KHPP option Position sensing feedback can be supplied by any pulse-based sensor - reed switch, Hall effect, or electro-optical. There is no need for special sensors or actuators. The RC2000A keeps track of both rising and falling pulse edges from the pulse sensor for increased accuracy The non-volatile memory can hold position and polarization data for 50 geostationary satellites The Adapti-Drive variable speed control system allows the user to specify the desired slow speed for each axis. The Adapti-Drive system will then adjust the actuator voltage (via a pulse width modulation scheme) to maintain the speed selected by the user. This alleviates the problems of poor speed regulation with varying direction along a given axis and environmental conditions associated with constant voltage slow speed systems The RC2000A is equipped with an RS-422 communications port. This allows the controller to interface with a PC. The communication protocol used is compatible with the popular SA-Bus protocol. Two IBM PC compatible programs are included with the controller Powers up and responds to keypad but complete operating condition unknown; offered AS-IS. Accessories Included: ops-manual and software on CD, power cord. Local pick-up okay.

INTERNATIONAL SHIPPING International shipments are shipped via the eBay Global Shipping Program. We ship the item to the eBay freight forwarder, who then transships it to its destination. Once the item leaves the forwarder, it is then the responsibility of eBay. That is, if it is lost or damaged, eBay is liable for it, and any shipping claims must be handled through eBay. The international shipping amount will be computed by eBay and will be shown on the auction page. In the listing, the buyer sees Estimated Shipping Charges and Estimated Import Charges which will be charged when eBay submits the invoice. Their shipping method and charges are non-negotiable. We do not ship internationally by any method other than the eBay Global Shipping Program! PAYMENT TERMS Avalon Equipment Corporation accepts the following forms of payment: PayPal (preferred method - item shipped quickly) MasterCard/Visa/American Expres Check (will delay shipment until check clears) i-Escrow (escrow fees to be paid by buyer) CA Residents add applicable county sales tax WA Residents add 8.8% Sales Tax TX Residents add 8.25% Sales Tax Including Shipping SHIPPING POLICIES Every attempt is made to ship on the same day of payment Shipping charges are added to final bid price Most items are InstaPak foamed to ensure that equipment arrives in the same condition as shipped Unit(s) are guaranteed to be in good working order upon your receipt. Calibration not included unless explicitly stated in auction Local pick up okay Shipping can be billed to customer's account if wished (domestic only); contact us for details. CLICK FOR LARGER VIEW:
