General product
SPECIFICATION:
DESCRIPTION: An RS232 to TTL Serial Interface Module is a device that facilitates communication between devices using RS232 (Recommended Standard 232) and TTL (Transistor-Transistor Logic) voltage levels. It acts as a bridge between RS232-level signals, commonly used in older computer systems and industrial applications, and TTL-level signals, which are prevalent in microcontrollers and modern embedded systems.
Here are some key features of an RS232 to TTL Serial Interface Module:
Signal Level Conversion: The module converts the RS232 voltage levels (-12V to +12V) to TTL voltage levels (typically 0V to 5V), allowing compatibility between devices using different voltage standards.
DB9 or DE9 Connector: The module typically comes with a DB9 or DE9 connector, which is the standard connector used for RS232 communication. This connector provides a convenient interface to connect the module to devices using RS232 signals.
Voltage Regulation: The module may include voltage regulation circuitry to ensure stable power supply for the TTL side.
Serial Communication Parameters: The module may support configurable parameters such as baud rate, data bits, stop bits, and parity, allowing you to adjust the communication settings according to your requirements.
Transceiver IC: The module often incorporates a dedicated RS232 transceiver integrated circuit (IC) to handle the signal level conversion and provide the necessary electrical isolation between the RS232 and TTL sideApplications of the RS232 to TTL Serial Interface Module include interfacing microcontrollers or other TTL-level devices with devices that communicate using RS232, such as legacy computer systems, industrial equipment, and certain communication modules.
