USB to TTL / RS485 Serial Converter Adapter

This module interfaces USB to RS-485.  It has Auto Direction control, making it easier to use as RS-232/TTL Serial Interface replacement.

RS485 is used for Serial Communications over longer distances than direct RS232 or TTL, and supports multiple units on the same bus (Multi-Drop)

Features

• Support Windows98 / ME / 2000 / XP / WIN7 / Vista / Linux / Mac
• Support devices with RS485 interface: surveillance cameras, video capture device, fingerprint attendance machine, PBX, CNC machine, microcontroller, etc.
• This converter provides two way serial communications signal
• Conversion between the RS485
• To and from a personal computer USB port
• Using virtual serial COM port
• Self-powered from USB w/ FT232RL + 75176 chips

Descriptions

• Standard: USB2.0 standard, backward compatible, in line with the standard RS485
• Direction control: the use of automatic data flow control, auto distinguish and control data transfer direction
• Baud: 300-9216000bps, automatically detecting the serial signal data rate
• Load capacity: support multipoint, each converter allows RS485 interface device to connect 32
• Interface Protection: TVS tube protection, USB self-recovery protection
• Size: Approx. 76 x 18.5 x 16mm

Package included

1 x Serial Converter Module

This converter provides two way serial communications signal conversion between the RS485
to and from a personal computer USB port using virtual serial COM port. Can have up to 32 devices on the bus.

The 4 jumpers connect the USB interface to the RS485 interface. If the jumpers are removed, the USB interface may be used as a TTL Level Serial port.

The drivers for Windows can be loaded by this program from FTDI:

Plugging the USB interface in then should show a Virtual Serial Port in Device Manager.

Self-powered from USB  Uses  FT232RL+75176 chips

Can be used to connect PC to one or more Arduino or other Microcomputers with RS-485 modules.
