Product Description 
Scope 

This document describes the functional requirements and software features contained in the 
newly designed 

tres900 Enhanced GEN2 Reader 

hereon

 

known as

 tres900s

. This document 

lists the product specifications, as well as performance, and operational criteria. 

Summary 

The

 tres900

 is the brand name for a new line of 902~928 MHz RFID Readers and Tags. We 

are  a  U.S.  based  company  comprised  of  seasoned  RFID  professionals,  including  engineers, 
marketing, and distribution specialists. We have designed a product line that is ideally suited to 
the parking, supply chain, document tracking, and many other markets. We will be selling our 
products  through  Systems  Integrators,  Distribution  and  OEM  channels.  The 

tres900s

  is 

designed and manufactured in the USA to be an enhance version of the present 

tres900

 GEN2 

UHF Reader.  
The 

tres900s

 is designed to reduce the number of electronic components needed for a traditional 

Product. This is accomplished by using a custom integrated RF IC in place of many individual 
components. The product will offer the following features: 

 

Wiegand Output Format, multiple and custom formats, 3-wire  

 

EMI protected I/O lines, i.e. 2 each for Wiegand Output, 1 each for Trigger Input, 2 each for 
RS232, 2 each for RS485, etc.  

 

Reverse Polarity and Over Voltage protection on the input voltage 

 

Serial RS232 + RS485 Bi-directional, used for configuration and data output 

 

Buffer (100 mS to 60 sec), read tag + output tag + buffer tag, read and output after buffered time 

 

Timer read (10 mS to 1 sec), time between read and output data 

 

Multiple tag reads, single tag process the strongest RSSI read from tags 

 

LED flashing and Audio (Piezo) tone for power on and for a tag read 

 

Ethernet TCP/IP Output, daughter board (optional) 

 

Controller functionality w/relay, Site Code and ID range configurable 

 

SPI Flash IC to restore the program and store valuable settings

The 

tres900s 

will be given an engineering part number
