125 kHz reader Syris RD200-LF
(Product ID: 1378)

The Syris RD200-LF is the most sophisticated RFID reader for 125 kHz and 134.2 kHz chips from our offer.

It is a USB plug-and-play device, which means that you don't need to install drivers.

By default, it works as a Keyboard Emulator, reading the chip ID and places on the display (inside the Excel table, Notepad, website, application input field, etc.).

It comes with software tools and it can be set to work as a serial port emulation reader as well.

It supports the reading of 125 kHz chips like EM4200, TK4100, EM4102, EM4100, encoded T5577 chips, 134.2 KHz chips, FDX-B, and more.

The RD200-LF reader is made by the trusted RFID reader manufacturer Syris Technology Corporation and operates on the frequencies 125 kHz and 134.2 kHz. It uses a standard USB interface and it stands out from the crowd in at least three features: 

- It reads well even the small 125 kHz tags with diameter 15 mm, 
- it supports different kinds of 125 kHz read only chips and even 134.2 kHz chips FDX-B which are usually used for animal identification. 
- and it comes with software tools so you have many options to customise the way it works.

 The RFID reader RD200-LF is usually used for:

-    Reading the chip UID code in various formats and place it into Excel table or Notepad
-    It can read the UID on Virtual COM port

Setup Options and SDK tools for software development

The SYRIS RD200-LF is by default a Keyboard Emulator reader and it reads the chip ID in the 8 HEX format. The popular reading format from other 125 kHz readers is 10 digits in the DEC format and could be set on RD200-LF, as well by simply choosing ID Format 8 HEX->10 DEC.

Its default enables the setting ‘Same Card Detection,’ which means that it will not read the same card twice if placed within the defined time period.

The RD200 reader includes a CD with many utility tools for setting up a reader and SDK software.

With the program RD100_RD200_RD300_Tools_V0271_20201204.exe you can set the format of the read UID code, control the buzzer, add prefix or postfix, set it as ‘AutoRead’ to automatically read data from memory or as Virtual COM reader, chip encoder, etc.

If you like to set is as a Virtual COM reader, you have to use the same software and simply upgrading the firmware with the other form a CD. When it works as Virtual COM, you get the UID code in the basic HEX format and it cannot be changed with the configurator. However, you need to change it after and this usually requires some programming. You can change the output format only when the reader is set as a ‘Keyboard Emulator.’ 

The CD provides software development tools, including API, sample codes for BCB6, VB6, VB.NET, and libraries for VC, VB, BCB, DevC, and C#.

The RD200 works on Apple computers and devices with Android OS, although the configurator is only designed for PC. If you set up the reader on a PC, then it will retain the settings on Apple computers and other platforms as well.

Reader connection and housing

The RD200 has a USB Mini-B connector on the housing and it comes with a black 1.5-meter-long cable with a standard USB-A connector on the other side. The cable is black and it has a shielding protection against electromagnetic interferences.

The Syris RD200 reader can be used with PC, laptop, tablets, and if you use a USB-A to USB-C converter, you can use it even on tablets or mobile phones. The converter is not included with a reader.

The housing is compact and nicely made. On the back of each reader is a label with the name of the reader and a bar code. On the top right corner, there is a LED light which is red when the reader is on standby, and it turns green when it successfully reads the transponder. 

Transponders and supported chips

Syris RD200-LF is suitable for working with different kinds of passive RFID transponders which operate on the frequencies 125 kHz and 134.2 kHz as well.

The most common types of transponders used with RD200-LF are RFID Cards, Key fobs, Stickers, Tags, and Wristbands.

The supported chis are EM4200, TK4100, EM4102, EM4100, encoded T5577 chips, and some 134.2 KHz chips with FDX-B modulation (not every animal chip).

This greater reading distance is achieved when RFID cards with EM4200 chip, but it works well even with other chips and smaller tags. We did some own tests and the EM4200 cards with rectangular antenna was read at a distance of 8 cm, the PVC disc tag with a 15 mm diameter, and the TK4100 chip is our smallest 125 kHz tag and was read at distance 3 cm.

Reading test

The reading distance between the proximity tag and the reader is affected by many different factors:

-    The quality of the reader and the tags.
-    The interferences of metal and electromagnetic signals
-    The distance defined by the chip manufacturers 
-    The size of the RFID tag antennas. 

We tested the reader RD200-LF and measured the reading distances for different kind of 125 kHz and 134.2 kHz tags form our offer. This is not an official test and it was made to inform you what reading distances you may expect with your application.

Below are the distances we measured with our test:
ID  RFID/NFC tag Reading distance with RD200-LF
1638  125kHz cards EM4200 with larger antenna for better reading 8 cm
1590  125 kHz EM Clamshell long range card 8 cm
1182 White 125 kHz RFID cards with chip TK4100 6 cm
1651 RFID key fobs with EM4200 chip 5 cm
1684 Thin RFID sticker with 125 kHz read-only chip 5 cm
1199 Dual frequency white RFID cards with HF and LF chips 5 cm
1406    RFID tag COB with 125 kHz chip 4 cm
1580 RFID Key fobs 125 kHz TK4100 3 cm
1037  Premium RFID key fob with 125 kHz chip  3 cm
1258 RFID disc tag with 125 kHz chip 3 cm

The chips that have not been successfully read or are not supported are EM4450, EM4550, EM4305, 7999, animal syringe tags, and. some other 125 kHz chips which are encoded by the different solution providers. For these kinds of chips, you can usually use only readers which are offered by the solution providers.    

Reader Applications

Some common uses for RFID readers RD200-LF are:

•    person identification for time attendance application
•    person identification for tracking and billing processes
•    person authentication for software applications
•    person authentication for access management 
•    goods, asset and equipment identification
•    contactless payments
•    animal chip management

The reader is not designed to work on a metallic surface. The reade’s magnetic fluxes will induce eddy currents within the conductor and will cause poor performance or the reader not to work at all.

To ensure that the reader will perform well, we recommend that you mount it on plastic, wood, or other non-conductive material with a thickness of at least 1 cm or more or you may use a special shielding material.
