7. ECTION 1 GENERAL INFORMATION Introduction Thank you for purchasing the Accurate Technology Inc Wireless Encoder Receiver Transmitter system These units are designed to be used as a wire replacement system between a ProScale Digital Readout DRO and a Readhead Encoder Typical applications for the RF system include situations where it would be difficult and or expensive to route cabling between the DRO and the encoder Examples include Encoder cable lengths over 20 feet Installations where the encoder and DRO are located in separate rooms and or buildings e Applications involving excessive motion of the encoder cabling Applications that would require the encoder cable being installed in the same conduit wire way with high voltage cables over long distances greater than 10 feet The RF system is easy to install and requires minimum maintenance It is backwards compatible with all previously manufactured ProScale measurement products including all Incremental and Absolute encoders The system utilizes RF transceivers with the ability to provide two way communications This helps to guarantee the reliable transfer of position information and provides remote annunciation of transmitter low battery conditions and encoder status The RF system incorporates IEEE standard 802 15 4 radio modules operating at 2 4GHz which yield reliable data communications with worldwide acceptance Typical operating range
