USB to RS 422/485 converter 4-way DB9 hub ( FTDI )

The product is a universal USB to RS422 / 485 converter, compatible with USB, RS422, RS485 standard, can be single-ended USB signal into four RS422 / 485 signal, providing surge protection power per line to ensure RS422 / 485 interface, RS422 / 485 terminal through the DB9 male connector connector makes it easy to achieve the USB host computer and multi-channel RS422 / 485 bus system and data transmission between devices.

The main means of communication:

1. Point to point four-wire full-duplex

2. Point to multi-point four-wire full-duplex

3. Point to point two-wire half-duplex

4. Point to multi-point two-wire half-duplex

In order to prevent signal reflection and interference, a matching resistor (parameter: 120Ω 1 / 4W) must be connected to the termination of the line when the converter is in full or half duplex wiring.

Performance parameters:

In line with USB1.0, 1.1, 2.0 standard;

Meet EIA RS422, EIA RS485 standard
