UT-8890, Interface Converter, UTEK
USB to RS-232/485/422,3 in 1
USB-A 2.0, male
Serial port DB9 male & terminal block
Baud rate: 300-921,600bps
Operating temp: -40℃ ~ 85℃
Features
- Point-to-point / four-wire full duplex
- Point-to-multipoint / four-wire full duplex
- Point-to-point / two-wire half duplex
- Point-to-multipoint / two-wire half duplex: When the converter operates in full-duplex or half-duplex mode, a terminal matching resistor (120Ω 1/4W) should be connected to prevent signal reflection and interference.
