# Transcore Encompass 4 RFID Reader (AVI)

TransCore's Encompass® 4 is a family of fully integrated, self-contained 915 MHz wireless radio frequency identification (RFID) readers that are specifically targeted at high performance applications in parking, security access, electronic vehicle registration (EVR) and traffic management. Each Encompass 4 reader includes a radio frequency (RF) module, digital signal processor (DSP), power supply, antenna (unless external antenna option is selected), input/output interfaces, and RS–232 or RS–422 serial communications interface.

The Encompass 4 family includes models capable of reading any two of the following standard protocols: Super eGo, eGo (ISO 18000 6B), American Trucking Associations (ATA), Association of American Railroads (AAR), and Interagency Group (IAG). Additionally, for compatibility with existing security systems, Encompass 4 can read half-frame and full-frame ATA tags and Wiegand formatted tags and identification cards.

All Encompass 4 readers provide unparalleled flexibility by offering a real-time clock; expanded tag read buffering; programmable RF power; 250 KHz programmable frequency steps; system integrity checking; and programmable group select. Encompass 4 readers are quickly and easily installed, tested, and maintained by TransCore trained, authorized personnel. The Encompass 4’s command set is compatible with TransCore’s SmartPass® and Encompass 2 readers.
