I. Summary
With rapid development of computer industry, USB is taking the place of
various kinds of traditional low speed peripheral interfaces. However, RS-232
interface designs are still used in many of the important facilities under
current industrial environment, therefore, converter is used by many users to
implement the data transmission from USB of a computer to RS-232
equipments.
UT-860 is a universal USB/RS-232 interface converter. No external power
supply needed. Compatible with USB and RS-232 standards, UT-860 is
capable to perform the conversion from single-ended USB signal into UART
signal of RS-232. DB9 male connectors are used for connection from RS-232
interface. The unique I/O circuit of the internal zero delay auto transceiver
contained in the converter controls the data stream direction automatically.
The converter is plug-and-play. All these features ensure a universal
application on all the existing communication software and hardware
interfaces.
The data communication rate can be as high as 300-921.6Kbps by the point-to-
point communication by UT-860 interface. Power indicator light and data
traffic indicator light are also available with the converter for malfunction
indication. Conversion from USB to RS-232 is supported.
II. Functions
UT-860 interface converter supports the following communication mode:
1. Point-to-point communication mode.
III. Hardware installment and application
Read the user manual carefully before installing the UT-860 interface
