Functional Description

DS200UDSAG is a Display/Keyboard Interface Board developed by GE. It is a part of EX2000 excitation system. This board provides the human-machine interface (HMI) functionality, enabling operators to monitor, control, and interact with system parameters locally. It integrates both a visual display and keypad input system and connects with other control components via serial communication, typically RS-232C.

Hardware Components

• A -24 V to 5 V switching power supply, capable of delivering a minimum of 3 A at 5 V, powers the board and its peripherals.
• The microprocessor core manages data handling, user interface logic, and communication protocols.
• RS-232C interface circuitry allows the board to communicate with other EX2000 system components or external diagnostic tools.
• The keypad scanning interface detects user input across multiple key switches and translates those actions into system commands.
• LED interface circuitry tracks key status and provides operator feedback via embedded indicators.
• A display driver handles communication with the onboard dot matrix display.
• PWM dimmer circuitry allows adjustable brightness for both the display and the status LEDs, enhancing visibility in different lighting environments.

Display System

• Two rows with 40 alphanumeric characters each.
• One additional row with 12 characters for compact status or control readouts.
• This layout allows for the clear presentation of system data, messages, and diagnostic information, supporting a wide range of operational and configuration tasks.

Keypad and User Input Features

• One keypad consists of 32 keys, divided into two sets of 16 configurable keys. These keys can be mapped to different control or monitoring functions depending on the system setup. Each key is paired with a status LED to provide visual feedback, such as on/off states or fault indications.
• The second keypad comprises 16 keys that are primarily used for numeric input, local mode control, and diagnostic navigation. These are essential for performing system calibration, configuration changes, and executing specific control commands directly from the panel.
