Escort Memory System HS900 PC-Bus Read/Write Controller an XT-type PC expansion board
Escort Memory Systems® (EMS) offers a field-proven Read/
Write Radio Frequency Identification (RFID) products and network interface modules. The system consists of Tags, Antennas and Controllers. Tags can be attached to a product or its carrier and act as an electronic identifier,
job sheet, portable database or manifest. Tags are read and updated via an EMS Antenna through any non-conductive material while moving or stationary.
The HS900 PC-Bus Read/Write Controller is an XT-type PC expansion board which serves as the interface between a PC, XT, AT or PCcompatible
personal computer and up to four HS-Series Antennas. The Antennas can be
used to both read and write data from the HS-Series Read/Write Tags. The connection between the PC-Bus Controller and each Antenna is via two twisted pairs (four wires), with a maximum cable length of 4,000 feet
(1200 meters). This is advantageous because the Controller portion of the RFID system is then afforded extra protection from noise that
could be generated by electrical equipment positioned near the Read/Write station. Interface between the PC and the HS900 is via 2KB dual-port RAM, which can be mapped into any available address of the PC’s memory.
Read/Write instructions for the HS900 are written into the dual-port RAM and read by the HS900’s on-board microprocessor. Once the Tag is read, the collected data is returned to the PC via the same dual-port. This Memorymapped nature of the HS900 makes interfacing fast and easy.
Sample interface routines are available in the popular C programming language. The HS900 is manufactured under the quality standards which have made EMS the industry leader in network interface modules
