USB-CIF31:USB to RS232 adapter(standard DTE) with LED

Convert cable from USB to RS232(standard DTE interface), 1 meter, with communication indicator, support traditional RS232 PLC prgramming cables.
USB-CIF31 is the real USB to RS232 interface converters. Under the control of computer-driven driver, the programming cable makes it possible for the computer's USB interface to simulate the traditional serial (known as COM interface), thus various existing programming software such as communications software, monitoring software and other applications can be normally used. The working power supply of this cable is directly from the USB port, but not the PLC programming interface. The two-color LED on the converter box indicates data’s transceiving status.
The RS232 ports of the USB-CIF31 are standard DTE interface (DB9M-Block, the same with the computer's serial port RS232). Its signal as shown below:

Pin signal Description
1 DCD Carrier signal
2 RXD Receive data
3 TXD Sent data
4 DTR Data ready
5 GND Signal GND
6 DSR MODEM ready
7 RTS request
8 CTS clean
9 RI Ringing signal

USB-CIF31 do a very good simulation as a RS232 serial port, and even direct operate hardware by I/O. for the user,just like to visit the physical RS232 ports. USB-CIF31 can be used to support majority of the traditional PLC cable programming, and this point is different from similar products on the market .the appendix will show the test results of the USB-CIF31 connection with various traditional RS232 interfaces with PLC programming cable communications.

USB device drivers should be installed before using USB-CIF31 programming cable, which are available on the CD-ROM sold together with the cable. And for the specific installation steps, please refer to the instruction files on the CD-ROM drivers, and details are not necessarily listed here.
After completing Driver installation, the corresponding COM port for the USB-CIF31 programming cable will be displayed in the “Device Manager” of Window. The step next is just to choose this COM port in the programming software and other application software and keep other communication parameters as in the Default settings. And the following steps are exactly the same as in the traditional programming cables with RS232 interfaces..
