SparkFun (PID 10124) Transceiver Breakout - RS-485

SparkFun (PID 10124) Transceiver Breakout -

This is a breakout board for the SP3485 RS-485 transceiver IC, which will convert a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps. This board requires a very low amount of power and can operate from a single +3.3VDC supply. This breakout board includes the SP3485 RS-485 transceiver, filter capacitor, and other components shown on the schematic. We've broken out the RS-485 output to three different connections: (1) an RJ-45 connector, (2) a 3-pin 3.55mm screw terminal, and (3) a 3-pin 0.1" pitch header; none of these output connectors come populated. Connectors (RJ-45, 3-pin 3.55mm screw terminal and 3-pin 0.1" pitch header) not included

ICP DAS USA ICP-I-7520 Isolated RS-232 to RS-485 Serial Converter with Din Rail Mount.

ICP DAS USA ICP-I-7520 Isolated RS-232 to RS-485

The I-7520 is an Isolated RS 232 to RS 485 Converter with Auto Tuning function, auto switching baud rate, and is made of fire retardant materials. Most industrial computer systems provide standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range, and networking capabilities. The RS-422 and RS-485 standards overcome these limitations by using differential voltage lines for data and control signals, which transparently converts RS-232 signals into RS-485 signals with no need to change any hardware or software. The I-7520 lets you easily build an industrial grade, long-distance communication system using standard PC hardware. Supports operating temperatures between -25 to 75C (-13F ~ 167F).
