USB to RS232/422/485 Converter

Name: USB to RS232/422/485 Converter
Brand: Atc
SKU: ATC-850

Stock Code: ATC-850

Opens a USB port onto RS-232, RS-422 and RS-485 buses

An industrial serial converter that plugs into the USB port of a computer. The host detects the device automatically and exposes it as a local COM port, so existing serial software needs no change.

Key specifications

Interface and connectorsComplies with the EIA/TIA RS-232-C and RS-485 standards. A Type-A connector serves the USB side; a DB9 male connector and six terminals serve the serial side.

SpeedCarries full-speed USB at 12 Mbps, and on the serial side up to 460.8 kbps for RS-232 and 921.6 kbps for RS-422/485.

Data formatHandles 5, 6, 7, 8 data bits; 1, 1.5, 2 stop bits; none, even, odd, space and mark parity. Flow control runs over RTS/CTS and XON/XOFF.

RangeAn RS-485 line takes up to 32 nodes and reaches out to 1200 meters.

Isolation and protectionApplies 15 kV ESD protection on every interface and 3500 V RMS, 500 VDC continuous isolation. It guards the RS-232 line with 600 W and the RS-422/485 lines with 1000 W lightning and surge protection per line.

Housing and environmentThe metal shell is anti-static, blocks interference and clips onto a standard DIN rail. It works from -20 °C to 70 °C and across 10% to 90% relative humidity.
