Base Band modem

&Modem Eliminator...

LCM16P is a complete and reliable base band modem to be used in point to point and multipoint communications on 2 and 4 wires leased lines, in full duplex and half duplex with fixed and controlled carrier. This modem is suitable for any telematic environment, for building, campus and local loop needs.

LCM16P is compatiblewith any base band modem, it can be used on leased lines which are lent by your public manager, owner of the lines themselves.

It is easy to programand it is in conformity with ITU-T V54 recommandation for diagnosticmanagement and tele- management, in point to point and multipoint mode.

This product comes from ASIC digicomtechnology used for DCE1 (completely digital modem for CDN network) and it is carried out also into version at 64 Kbit for special connections (LCM16P64) at high speed in local point to point environment without cascade connections.

LCM16P specifications

The Digicom LCM16P is a highly versatile and compact LCD module designed for various applications, catering to both hobbyists and professionals alike. Renowned for its ease of integration, the LCM16P offers a multitude of features that make it an ideal choice for embedded systems, industrial automation, and consumer electronics.

One of the most notable features of the LCM16P is its 16x2 character display capacity, capable of showing two lines of 16 characters each. This allows for the representation of a considerable amount of information in a space-efficient manner. The LCD utilizes the well-known HD44780 controller, ensuring compatibility with numerous microcontroller platforms. This widespread support simplifies the integration process, providing numerous libraries and resources for developers.

The LCM16P employs a standard parallel interface for communication, operating typically at 4-bit or 8-bit data formats. This flexibility allows developers to choose the method that best suits their application’s needs. Additionally, it operates on a 5V power supply, making it conveniently compatible with most commonly used microcontrollers.

In terms of display technology, the LCM16P utilizes a high contrast LCD panel that ensures visibility under different lighting conditions. Its background illumination is often available in various colors, enabling users to customize the display’s appearance for specific environments. Moreover, the module includes a built-in character generator that allows users to create custom characters, significantly broadening the creative possibilities for displaying information.

Durability is another key characteristic of the LCM16P. The module is designed to withstand the rigors of industrial use, with a robust build quality that enhances its lifespan. It typically features a wide operating temperature range, making it suitable for both indoor and outdoor applications.

Furthermore, the LCM16P supports various communication protocols beyond the standard parallel interface, including I2C and SPI options in some configurations. This adds another layer of flexibility, allowing users to connect the display with minimal pin usage, which is particularly advantageous in compact designs.

In conclusion, the Digicom LCM16P is a feature-rich LCD module that stands out for its ease of use, flexibility, and durability. Its compatibility with a range of microcontroller platforms, coupled with customizable display options, makes it an excellent choice for a diverse array of applications, from simple projects to complex industrial systems. Whether for educational purposes, prototyping, or full-scale deployment, the LCM16P is an invaluable tool for developers and engineers alike.
