Abstract
A dual mode transponder for engaging in RF communications with a roadside reader from a vehicle. The transponder includes an antenna, an electronic toll collection (ETC) component, and an external interface. The ETC component implements a pre-defined ETC communications protocol to detect and interpret received signals and generate response signals when operating in an ETC mode. The ETC component also includes a bypass port. The external interface is coupled to the bypass port and has an external port for receiving input signals. The ETC component includes a bypass module for receiving a bypass instruction and entering a bypass mode. In the bypass mode the ETC component refrains from implementing the ETC communications protocol. Instead, the ETC component transmits the input signals relayed from the external interface to the ETC component to the reader.
