A wireless modem employs a radio frequency (RF) transponder system components to remotely access the memory of an electrical or electro-mechanical device by providing an exciter/reader/writer (ERW) circuit free of electrical contact with the electrical or electro-mechanical device and a transponder including a transmit/receive antenna, a reading circuit, a programming circuit, and a transponder memory. The transponder memory is directly connected to the device memory. TheERW circuit initially generates an RF excitation signal powering the transponder. In response to the RF excitation signal, the transponder generates a RF response signal using the reading circuit that is transmitted back to the ERW circuit. The RF response the ERW circuit, which in turn generates an RF write signal that is transmitted to the transponder. The RF write signal powers the transponder and programs the devicememory using the programming circuit of the transponder.

L'invention est un modem sans fil utilisant les éléments d'un transpondeur radiofréquence (RF) pour avoir accès à distance à la mémoire d'un dispositif électronique ou électromécanique. Le modem de l'invention contient un circuit d'excitation, de lecture et d'écriture (« ERW ») sans contact électrique avec le dispositif électrique ou électromécanique et un transpondeur comportant une antenne d'émission-réception, un circuit de lecture, un circuit de programmation et une mémoire directement connectée à la mémoire du dispositif. Le circuit ERW produit initialement un signal d'excitation RF qui alimente le transpondeur. En réponse à la réception de ce signal d'excitation RF, le transpondeur produit un signal de réponse RF à l'aide du circuit de lecture et le transmet au circuit ERW qui à son tour produit un signal d'écriture RF qui est transmis au transpondeur. Le signal d'écriture RF alimente le transpondeur et programme la mémoire du dispositif en utilisant le circuit de programmation du transpondeur.
