1000 Brown Rd. Auburn Hills, MI 48326 248.754.1900 jrautomation.com TPM STEM OVERVIEW The purpose of this section is to provide an overview of the TPM valve stems. The scope of this manual is to cover the operation of the JR Automation antenna systems that communicate to the stems, not detailed information on the TPM valve stems themselves. But a general overview of how TPM valve stems operate will help the users understand the operation of the antenna equipment.
1000 Brown Rd. Auburn Hills, MI 48326 248.754.1900 jrautomation.com LF TRANSMISSION (125KHz) THIS MODEL ONLY GENERATES A CONTINUOUS LF TRANSMISSION The JR Automation TPM Antenna systems were developed to utilize the LF (Low Frequency) transmission to collect data from the TPM stem. The TPM stem responds with the 125 kHz wakeup signal can be of 2 different types – Continuous and Modulated LF. Each is described below. Continuous LF: A stem requiring a continuous signal or a signal with no change.
1000 Brown Rd. Auburn Hills, MI 48326 248.754.1900 jrautomation.com RECEIVING UHF SIGNALS After the TPM stem receives the wake up signal it will transmit a UHF data package. The stems transmit data in one of two frequency bands 315 MHz and 433 MHz bands depending on the stems design. Typically, 315 MHz is used in the U.S. and 433 MHz is used in export vehicles. The frequency used is governed by the FCC in the United States.
