The USB to RS485 Converter Adapter module support WIN7 XP Vista Linux Mac OS provides an easy to use RS485 interface by means of a Virtual Com Port on the user’s system.
There are no command structures, whatever is sent to the Virtual Comm Port is automatically converted to RS485 and vice versa. The module is completely self-powered from the USB bus.
Controlling / Communicating with RS-485 devices from your PC has never been easier! This device is plug-and-play. It shows up as a serial/com port and is accessible from applications or hyper-terminal.
This converter provides half-duplex RS-485 communication. The Baud rate range is 75 bps to 115200 bps, maximum up to 6 Mbps. No need of external power supply for operation.Applications :

Our company deals in a variety of timers, we also provide A Type Timer to our clients. A TYPE timer is available with unique features such as two operational modes. They can be operated from device low power oscillator or in an asynchronous mode from an external clock source. Timer A type generally finds its application in Real time clocks. We offer these reliable and high performance timers at market leading prices.
This RFID Reader module has a built–in antenna in minimized form factor. It is designed to work on the industry standard carrier frequency of 125KHZ.
This LF reader module with an internal or an external antenna facilitates communication with read-only transponder – type UNIQUE or TK5530 Via the air interface. The tag data is sent to the host systems via the wired communication interface with a protocol selected from the module both TTL and weigend protocol.
The LF module is best suited for application in access control, time and attendance, asset management , handheld readers, immobilizers and other RFID enabled application.
Connect – 5 volts and GND
TX- TTL output can be directly connected to microcontroller (To convert TTL to UART use converter board).
D0 & D1 - Is used for weigend protocol.
· Connected – 5Volts and GND
· Plugs and play , needs +5V to become a reader
· Buzzer indicates tag reading operation
· Compact size and cost effective.
