Description
HM01 USB to RS485 converter
USB-RS485 converter HM01 serves as a converter from a USB standard to a half duplex RS485 standard (ANSI TIA / EIA 485-A-1998; Approved: March 3, 1998; Reaffirmed: March 28, 2003).
The device is powered directly from the USB port, and there is no need for additional external power. Suitable for most applications, including industrial, commercial and general office. It provides two-way half-duplex communication between the sUSB and the RS485 bus.
It contains reliable components from manufacturers such as Analog Devices and Silicon Labs that guarantee top-notch performance.
The galvanic isolation between the inputs and the output of the circuit is 4 kV.
The light-emitting diodes signal the presence of power (red), data transmission (green) and data reception (yellow), making it easy for the user to operate the USB-RS485 converter HM01.
The device at its output contains a line lock of 120 Ohm.
