Serial to wi-fi converter is a wireless networking device, which is used for connecting rs232rs485 serial equipment to your pc over a standard wi-fi network. This device can be configured through android mobile phone or pc. Data can be transferred using tcpip or udp or http protocol using the 802.11 bgn wireless infrastructure which allows you to use existing wi-fi network connectivity. This device allows you to connect a standard rs232rs485 serial device to any secure or open wireless network or access point. This converter also support modbus communication over rs485 serial interface with the connected device.

Our range of converters include: rs232 to rs485rs422, usb to rs232 & usb to rs485, usb drive module, wigand to rs232 serial etc. Usb 232 m is a product that connects to a pc�s usb port providing a high-speed asynchronous, for the rs 232 serial port to communicate with rs 232 devices. The usb 232 m is provided with txdrxd leds to indicate communication status and supports a maximum speed of 500kbps. Rs 232 serial port is furnished with a 9 pin d-type male connector, which is similar to that found behind a pc. When the device is connected to pc�s usb port, the usb 232 m is automatically detected and is installed as a native com port, and is compatible with existing serial communication applications. Users can addremove this device once plugged into the usb port of the pc, since this appears as a com port the serial interface consists of two data signals � txd (transmit) and rxd (receive) as well as six control signals � rts, cts, dsr, dtr, dcd and ri. The serial interface supports rtscts, dsrdtr and x-onx-off handshaking the product is programmable to support a variety of data formats and baud rates

Ead is a protocol converter which transmits the serial data sent by equipment as tcpip packets to the lannetwork and converts back the tcpip data received from the lannetwork as serial data to the equipment. Ead also supports udp protocol for broadcasting the applications. Ead�01 is of low cost, serial rs 232rs 485rs 422 to ethernet lan 10100 mbps connectivity system using the tcpip protocol and is based on arm cortex m4 high speed 32�bit microprocessor. Ead�01 has built-in web server for the configuration through web browser and a factory default load switch to load the default configuration setting.

Application : Protection, Isolation

The rs 232 serial port isolator � iso 232 m is primarily intended to provide complete isolation between expensive computer or system from the serial device, so that they are protected against any inadvertent damage due to electrical disturbances. The iso 232 m also provides necessary immunity to a computer or a system against electrical noise and differential ground. Iso 232 m is available as a compact unit enclosed in a plastic casing, which takes power from the supplied power adaptor. The converter is populated with surface mount components for good reliability and to reduce the size. At the same time, it is equipped with good and reliable isolation to data signals and protection to serial port from high voltage (2500 v)

Application : Protection, Isolation

Input Voltage : 5V

Converts radio waves returned from the RFID tag into a form that can be passed on to Controllers, which can make use of it. The tags and readers have to be tuned to the same frequency to communicate. The frequency supported by the reader is 125 KHz. Designed as a Plug & Play Module and can be plugged on a Standard 300 MIL – 28 Pin IC socket form factor. Supports reading of 64 Bit Manchester Encoded cards. Pins for External Antenna connectio

4 Port Device Server is a protocol converter which transmits the Serial Data sent by Equipment as TCP packets to the LANNetwork and converts back the TCPIP data received from the LANNetwork as Serial data to the equipment. EAD also supports UDP Protocol for Broadcast applications. EAD-04 is a low cost, Four Serial RS 232 to Ethernet LAN 10100 Mbps connectivity system using the TCPIP protocol and is based on ARM Cortex M4 High speed 32 � bit Microprocessor. EAD�04 has built-in web server for configuration through Web browser and a factory default load switch to load the default configuration setting. This also support one RS 485422 Serial Port for connecting over LAN.

The eth io � 2.0 unit enables the user to monitor the analog and digital inputs, control relay outputs. The status of the slave units are connected to it through modbus protocol. A single box of eth io � 2.0 contains 8 analog inputs, 8 digital inputs, 8 potential free relay contacts, a query based response unit on the rs 232 bus, and a rs 485 port to connect to the slave units. Up to 6 slave units can be connected through the rs 485 interface. Using the lan (rj45 connection), all of the information of the inputs and the status of the different units which are connected to it , will be sent to the main server.

Can (controller area network) data logger is a standalone data collecting unit, which can collect and store the data from can bus by sending appropriate queries. It has storage capacity up to 16 gb, to store captured data. The device supports communication rate from 20 kbps to 500 kbps.
