Description

USB-485 Converter USB To RS485 with TVS Transient Suppression Protection Function with Signal Indicator

Product introduction:

• This product is completely designed in accordance with industrial-grade standards. It has anti-lightning and anti-static shock, limited slope drive, effectively restrains electromagnetic interference and solves the superposition of valid and invalid signals on the transmission circuit. Error-free data transfer rate up to 115200bit.

• Therefore, the communication data line of this product can be used with ordinary data lines. You can rest assured about the performance of our products!

Product Features:

• With TVS transient suppression protection function to prevent the internal chip from being damaged due to level incompatibility, with receiving and sending lights; anti-high pulse voltage protection function. Super convenient wiring method.

• Overvoltage Transient Protection

• Lightning protection, anti-static discharge, anti-surge impact, transient interference such as overvoltage caused by power system switching, etc., for these transient interferences, we use protection circuits to protect and bypass harmful transient energy. to ground

Applications

• Parameter setting, data transmission communication, etc. of various devices with RS485 port. LED display communication data (many display companies have used it in batches, and it is compatible with almost all manufacturers' control cards and is very easy to use after testing)

• Better support for notebook USBO than similar products

• Fully compliant with USB2.0 standard, compatible with USB1.1

• Can work in the extended temperature range of -40℃ to +85℃ Supports plug and play and hot swap (USB side)

• The communication distance can reach 1.2KM, and it has the anti-dry ability of the industrial site.

Features

RS485 communication adopts special industrial grade 485 chip, which has the following characteristics:

• true failsafe receiver

• Robust slew rate control for error-free data transmission

• Enables error-free data transmission up to 500kbps

• The receiver has 1/8 unit load input impedance

• Up to 32 transceivers can be attached to the bus.

Instructions for use

• First download and install the driver, then wire the device according to the page method, then insert the RS485 module to the computer, check the mapped serial port number in the system's "Device Manager", and then select the corresponding serial port number in your application software

• (Some device software automatically matches, no need to select settings separately), open the serial port to send and receive data, so simple.
