How the compatible Casi-Rusco C10106 40-bit (ProxLite) works
The Casi-Rusco C10106 40-bit (ProxLite) is a 125 kHz low-frequency proximity credential — the band most legacy prox readers use. Its data structure is 40-bit C10106: non-standard FC split; ~38-bit card, facility number must begin with '15', card serials 0-457,681; Non-standard pulse scheme; reader internally re-manipulates the 40 bits before sending to the panel (proprietary, undisclosed by UTC/Lenel). When you present a credential, the reader decodes that exact structure and passes it to your access-control panel as a card number it recognises.
We build the compatible Casi-Rusco C10106 40-bit (ProxLite) by encoding the identical data structure onto a programmable T5577 chip. Once written, the reader cannot tell the difference between our credential and the original — it presents the same bits, the same facility code, and the same card number. That is what "compatible by specification" means: not a generic look-alike, but a credential engineered to read exactly as the original does, matched to your facility code and card-number range.
To order, tell us the part number or format printed on your existing Casi-Rusco card, along with your facility code and card-number range, and our specialists confirm the encoding before anything ships. Bulk and reorder quantities are welcome — pricing is a fraction of OEM list, and every credential is verified to read on your existing equipment.
