Serial data can be transmitted in both directions (half duplex) at a data rate up to 2.5Mbps. The modules operate from a standard 5V power supply and use 5V logic levels allowing them to be interfaced to the hardware serial ports of microcontrollers such as Arduino\/PIC etc. Direction of communication can be controlled with just one digital pin (see diagram). It is also possible to connect multiple modules together for communication between 2 or more devices. For even greater distances two modules can be configured as a repeater.<\/h3>\n<p>Each module contains one driver and one receiver. Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.<\/p>\n<p>Data connections to the modules are provided by a standard 0.1\u2033 pitch header pins which can also be soldered into standard prototyping PCB and breadboards. Screw terminals provide convention connection to the actual data cable.<\/p>\n<p><strong>pinout:<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>VCC\u2026\u2026..5V<br \/>\nA\u2026\u2026\u2026\u2026Non-inverting Receiver Input and No-ninverting Driver Output.<br \/>\nB\u2026\u2026\u2026\u2026Inverting Receiver Input and Inverting Driver Output<br \/>\nGND\u2026\u2026.0V<\/p>\n<p>R0\u2026\u2026\u2026.Receiver Output (to Rx pin of microcontroller)<br \/>\nRE\u2026\u2026\u2026.Receiver Output Enable (Low to enable)<br \/>\nDE\u2026\u2026\u2026.Driver Output Enable (high to enable)<br \/>\nDI\u2026\u2026\u2026..Driver Input (to Tx pin of microcontroller)<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>TTL to RS485 Module This low power transceiver module is based on the Maxim MAX485 IC to allow serial communication over very long cable runs (up 4000 feet \/ 1200 meters).
