Gen2 Passive Reader


EPC Class 1 Gen 2 Passive RFID products comprising good performance multi-protocol tags and readers, enables solutions for transportation & mobility area and in medical & health specification. It is the first products locally produced by USM. It features range is about 2-7 meters long. This product is based on Passive RFID reader. The reader interfaces with personal computers (PC) via RS-232 serial communication. It is also integrating the TCP/IP network interface to the reader so that it would be able to download data from the tags that are being read to a PCs or Computer Servers via Local Are Network (LAN). It will be cheaper product compared to similar products in the market.

Passive RFID reader supported multi-protocols of EPC Class 1 Gen 1, EPC Class 1 Gen 2 and Read and Write protocols. However for these products, its technical specification supported the protocols of EPC Class 1 Gen 2.  The operating frequency is at UHF 919-923 MHz. The architecture used for these project are 8051 core processor, 32 KByte RAM and 32 KByte Flash.  Power consumption for these products can be considered lower as 9-12V DC 500 mA. In order to show operation message and key-in data these products used LCD display of 16 x 2 character and keypad of 3 x 4 matrix keypad.

As mentioned before, these products use RS-232 and LAN TCP/IP for communicating these products with other computer or any other controller board such as Peripheral Interface Controller (PIC) from Microchip and 68HC’s families from Motorola. The serial RS-232 commonly connected through DB9 and LAN TCP/IP connected through RJ-45.

Network protocol for these products is Transmission Control Protocol/Internet Protocol (TCP/IP.), the suite of communications protocols used to connect hosts on the Internet. TCP/IP uses several protocols, the two main ones being TCP and IP. TCP/IP built into the UNIX operating system and used by the Internet, making it standard for transmitting data over networks.
