RS-232 DB9 Pinout and Usage What is RS485 Modbus protocol? One of the main features that differs RS485 communication from any other serial communication is the format of data exchanged. While RS232 devices connect over text (ASCII) protocols, most RS485 devices use Modbus. Modbus is a ser...
When this switch is in the “Off” position the receiver is enabled only when the RS-485 driver is disabled for use in 2-wire mode to prevent the transmitted data from echoing back on the RS-232 side. Connections Integrate – Expand – Simplify The RS-232 port has a female DB9 ...

Pinout Applications Example Duty Cycle & Pulse Width Modulation (PWM) Modes In duty cycle mode, the transmitter displays ON or OFF time in percent from 0% to 100% of period for repetitive pulse trains. In the illustration, duty cycle in percent is 100 x t/P. In pulse width modulation...
