USB232GH3 type 




 The world's smallest, most new generation 

 Across the high-speed optical micro-USB / serial converter 



 The world's smallest high-speed optical converter every USB/RS-232/485/422 0-115.2Kbps 



 Adhering to a new generation of Boshi USB232GH3 high-speed optically isolated micro-USB / serial converter Boshi consistent feature of the converter, with ultra-small form factor, RS-232, RS-485, RS-422 general-purpose, can be virtual local COM ports (COM1 -COM256), 2500V optical isolation, support 0-115200bps rate. No need to modify the existing serial communication software. 

 The Boshi USB232GH3 is the world's smallest optical separated USB / serial converter. USB232GH3 is Boshi latest generation of products, and USB232GH1 size the same, but the driver changed the FTDI. Patented product, Beware of imitations! Patent No.: 200 630 307 752. 



 The distinction of four kinds of products 
 Different in shape and drive the same (PL) 
 Different in shape and the same driver (FTDI) 

 The same shape (large), different drive 
 USB232GH (large) 
 USB232GH2 (large) 

 The same shape (small), a different drive 
 USB232GH1 (small) 
 USB232GH3 (small) 




 Boshi USB / serial converter USB and RS-232/RS-485/RS-422 serial devices to communicate with each other, a protocol conversion device (USB protocol - serial communication protocol). Communication host (USB) and RS-232/RS-485/RS-422 between serial devices, whether it is communicating hosts send a message to the specified RS-232/RS-485/RS-422 serial devices or RS-232 / the RS-485/RS-422 serial devices to send information to the designated host of communication, can be easily and accurately transfer. The Boshi USB232GH3 product to provide a USB port, an isolated RS232 / RS485/RS422 serial port. 

 Hardware Installation 
 Will USB232GH3 USB / serial converter USB estuary into the computer's USB port can be. 

 RS-232/485/422 serial port side in the the Boshi USB232GH3 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 USB232GH3. Note RS-485 and RS-422 communications, suggested that the grounding line (5 feet). RS-485/422 without jumper selectable. RS-485/422 signal reference ground GND of the RS-232 is the same.

 USB232GH3 achieve 2500V optical isolation between the USB and serial (RS-232/485/422). The highest communication rate of USB232GH3 of RS-232/485/422 to 115.2Kbps. The Boshi USB232GH3 built-in 600W anti-lightning surge protector. 



 Software Installation 

 The USB232GH3 the driver supports Windows me/2000/XP/vista/7, LINUX, iMAC, etc., with Boshi USB232GH2 driver software (FTDI driver). 

 Follow these steps to to install USB232GH2 converter driver software: 

 USB232GH3 USB cable plugged into the computer's USB port, the computer will automatically detect USB232GH3 and displays the "Found New Hardware" will USB232GH3 supporting the CD into the drive of the computer, the computer will automatically find the drivers automatically find, and finally press "Finish". 

 Users can view the "Control Panel" "System \ Device Manager \ port" will be automatically assigned to a new COM port number in USB232GH3. Remember the COM port number. Users can view the "Control Panel" "System \ Device Manager \ port" will be automatically assigned to a new COM port number in USB232GH3. Remember the COM port number. If you want to change the COM port number under Windows XP, desktop à My Computer \ attribute à Hardware à Device Manager à port à communication port (find USB232GH3 of) \ Properties à port settings à Advanced àCOM port number, the user can change the COM port number. Can be forcibly changed to the COM port number is already in use. 



 Performance characteristics 

 We can look at the real ability of USB232GH3 The product has a the Boshi RS-485 zero-latency automatic switching core technology, built-in DB-9 plug a USB-UART interface chip, an RS-232 interface chip, an RS- 485 interface chip, an RS-422 interface chip, the DC / DC isolated power supply and 2500V optical isolation, etc., but also with 600W anti-lightning surge protection. 

 From the ease of use, new of USB232GH3 to switch to a fixed USB cable, do not have to worry about the USB cable loose. If you still prefer the previous shape, Boshi also continue to provide models for USB232GH2 of products for users to choose the same features and use a large volume. 

 - Direct the extrapolation USB port, no external power supply! - The world's smallest the isolation USB/RS-232/485/422 converter! 

 - Serial RS-232/RS-485/RS-422 Universal! - Automatic identification serial number, as a new COM port! 

 - The software simply modify the serial number, do not have to re-write. - Driver software with the Boshi USB232GH2 converter. 

 Appendix: the FTDI, and ProLific USB-UART difference 

 In most cases, the user may experience less than the difference between the two. But they are clearly differentiated. On the driver, after the WIN XP/VISTA/7 ProLific only provide the driver of the SETUP.EXE executable form. Can not say the driver of SETUP.EXE is not good, but there are a number of occasions WINDOWS reminded found that USB devices need to install the driver and requested to point out the location of the driver, time, SETUP.EXE is invalid, you must run SETUP.EXE and then plug USB device the job. Such as access Ethernet / USB server, WINDOWS can not automatically recognize the USB device required to specify the location of the USB driver, run SETUP.EXE to drive on the local computer is not valid, because the USB device is not local but on the remote. FTDI's driver INF configuration file with the installation of information instead of the EXE file in the WINDOWS version of GM, would not there SETUP.EXE. The Boshi electrons through a large number of applications that: when used alone, the FTDI with ProLific of USB-UART almost experience any difference, but when cascaded with other products used in sending and receiving data in some cases feel ProLific obvious delay FTDI almost no delay. FTDI's advantage is that the delay is much smaller than ProLific, although most cases do not affect the user. FTDI's costs are significantly higher than ProLific, we think it should have its reasons. ProLific the advantage of application is very large, and the product specification is complete, accounting for the majority of market share.
