DS215UDSAG1A is a Display/Keyboard Interface Board with EPROM manufactured and designed by General Electric as part of the Mark V Series used in GE Speedtronic Gas Turbine Control Systems. A Display/Keyboard Interface Board with EPROM (Erasable Programmable Read-Only Memory) is a hardware component that facilitates communication between a display unit, a keyboard, and a microcontroller or computer system. The EPROM stores firmware or software instructions that control the operation of the interface board. Here's a high-level overview of the components and functionality of such a board:
Display Interface: The board provides a means to connect and control a display unit, such as an LCD (Liquid Crystal Display) or LED (Light-Emitting Diode) panel. It includes the necessary drivers and circuitry to interface with the display unit and display text, graphics, or other visual information.
Keyboard Interface: The board includes circuitry to connect and interact with a keyboard or keypad. It may utilize a matrix or other keyboard scanning technique to detect keypresses and send corresponding signals to the microcontroller or computer.
EPROM: The EPROM is a non-volatile memory chip that stores the firmware or software instructions for controlling the display and keyboard interfaces. The EPROM is programmable, allowing the firmware to be written during the manufacturing process or updated later if necessary.
Microcontroller/Computer Interface: The interface board typically connects to a microcontroller or computer system using standard communication protocols such as UART (Universal Asynchronous Receiver-Transmitter), SPI (Serial Peripheral Interface), I2C (Inter-Integrated Circuit), or parallel interfaces. This connection enables the exchange of data and commands between the display/keyboard interface board and the controlling device.
Power Supply and Signal Conditioning: The board may include voltage regulation and signal conditioning circuits to ensure proper power supply levels and signal integrity for the display and keyboard components.
