---- To achieve serial communication via the Internet, WiFi cloud! 



 Product Innovation Award won in 2011, the 10th Chinese Automation Annual Award 

 WF232I type WiFi / serial converter adhering to the to Boshi converter consistent features: ultra-small form factor (80 * 23 * 47mm), IEEE802.11b / g standard wireless AP WiFi signal conversion for the RS-232/485 / 422, the virtual can become a local serial port, you can also achieve serial communication via the Internet WIFI cloud! 

 The Boshi WF232I is the world's smallest, but also the easiest WiFi / serial converter. The product itself with communication settings. Boshi new generation of patented products, Beware of imitations! Patent No.: 201 120 297 328

 WiFi signal of the wireless AP the Boshi WF232I wireless WiFi / serial converter will convert the RS-232, RS-485 or RS-422 serial port. WF232I high-performance, low-power IEEE802.11b / g wireless communication chip, built-in high-performance microprocessor the transparent transmission of serial data, work in the 2.4GHz global open ISM band, license-free use, can be widely used in various occasions short-range wireless communications, industrial control field. The product itself can be its own serial port to the computer with the configuration program the communication rate, format, encoding settings, without any other programming device. WF232I either one-on-one communication, can also be multi-machine communications, multi-machine communication method is equivalent to the serial port of the multiple independent address. Virtual local serial port, no need to modify the existing serial port software. 



 1, the hardware installation 

 WF232I the hardware installation is very simple: connect the power supply, install the antenna can be. Next to the power outlet, a small LED (light emitting diode), LED will be lit when the product is powered. 

 WF232I can directly access the WIFI port of the computer, without going through the wireless AP. At this point WF232I is equivalent to a wireless computer expansion RS-232/485/422 port. WF232I the IEEE802.11b / g standard (11M/54M). 

 WF232I's also in conjunction with the IEEE802.11b / g wireless AP. With the wireless AP can be achieved through the Internet cloud serial communication. The If multiple WF232I access can also be achieved in the same wireless AP network wireless communication between multiple WF232I. 

 WF232I DB-9 pin serial port 2 usefulness: a transparent transmission mode as WiFi converter serial mode is set used on WF232I product reset settings. Note that the computer's RS-232 port to connect to WF232I the RS-232 port, as long as RXD, TXD, GND can, but must be RXD-the TXD cross-connect. 

 RS-232/485/422 serial port side in the the Boshi WF232I product is a DB-9 pin holder, with the RS-232, RS-485, RS-422 all pins. Exactly the same as RS-232 port and PC DB-9 pin RS-232 port 2,3,5-foot allocation. As RS-422, T +, T-refers to send out from WF232I products, the R + R-point products within the receiver. Note RS-232/485/422 communication suggested that the grounding line (5 feet). RS-485/422 signal reference ground GND of the RS-232 is the same.
