These boards allow the "WiFi" to interface a device featuring a RS232 serial port. Using the included software you can create a virtual COM port on a PC and set its parameters. You can also set the parameters for the Wifi network communication. You must consider, however, that a remote serial port has longer latency time than a cabled one. The maximum latency time is 50ms so issues with the communication software must be expected.

WS4 - RS232 to WiFi Converter on 5-24V

The WS4 converter is suited to different industrial applications, whenever it is necessary to turn a serial RS232 communication into wireless. It can be provided with a plastic casing (shown in the picture above) or "board-only", allowing for an easier integration with machine tools, switchboards or any other kind of equipment. If installed within a metallic container, the WS4 converter's antenna must be placed externally; for this particular situation, we can provide the necessary antenna cable extension.

The Sinai WS4 3.0 boards can connect to already-existing infrastructure networks or work in soft-AP mode, which allows the board to emulate an ad-hoc connection. Along with the boards, Sinai provides the WS4 Configurator utility and, on demand, the WS4 Redirector application, that can be used to connect to the board in ad-hoc mode and quickly set-up a serial communication. The prerequisites are using Windows 7 or later operating systems and the presence of a WiFi adapter.

Sinai can develop custom versions of both the WS4 boards and accompanying software.

PS1 - RP-SMA Antenna Extension for WS Modules

This extension is compatible with all WS boards and allows the antenna to be installed at up to one meter from the WS module. It is used to install the antenna outside the device, for example inside a cabinet.

Other models:

WS1 - 5V OEM RS232 to WiFi Converter

The board is especially suited for integration on industrial machines, where little space is available. The most common use is turning a cabled system into a wireless one. Given its small size, it can often be installed in every machine able to provide a 5Vdc power supply. It is ideal for embedded applications, where the producer of the device can integrate and cable the Wifi board himself. If a serial port is needed, the WS1 board has a built-in RS232 port for bypassing the Wifi communication. The WS1 also features a cable that allows you to install the antenna at a maximum distance of 100m from the board. This is important if you wish to install the antenna outiside the device.

Features:

• 5Vdc power supply (300mA maximum)

• RS232 interface for connecting to a PC

• bypass of the Wifi connection

• 2 outputs for status LEDs

• Antenna output: 100mm wire with screw connector

• 2.4GHz antenna included

• Board size: 65 x 45 x 15 mm
  

WS2 - RS232 to WiFi Converter on 9-24V DIN bar

This board is well suited for installation inside cabinets. It is tipically used to wirelessly connect a PC to a PLC or any other device equipped with a RS232 serial port. WS2 is mounted on a DIN <guida> support and accepts voltages between 9 and 24 Vdc. It features an antenna fitted on a R-SMA screw connector. The antenna can be placed at up to one meter from the board using a PS1 extension.

Features:

• 9 to 24 Vdc power supply (200mA maximum)

• RS232 interface via a 9-pin D-Sub connector

• 2 status LEDs

• Antenna output: R-SMA screw connector

• 2.4GHz antenna included

• Board size: 108 x 60 x 40 mm

• DIN bar support

WS3 - 2 Port RS232 to WiFi Converter on 9-24V DIN bar

As WS2 but features 2 RS232 serial ports.
