G233 - Diagnostic Board with Front Display

Interactive OLED Display

The G233 is a 3U CompactPCI Serial board featuring a 3.12" OLED display for showing diagnostic status and error messages. Two control buttons at the front panel can be used for user interactions, e.g. scrolling or doing set-up. Eight programmable LEDs are provided for user-defined functions.

Simpler Troubleshooting and Less Downtime

The G233 provides an easy to use, interactive diagnostics interface suitable for train maintenance personnel during troubleshooting or performing routine service checks. The displayed information is fully customizable. Any status or fault message visible to the host CPU can be sent to the G233 and shown on the display or represented by the LEDs.

Shorter Development and Integration Time

The native onboard web browser communicates via backplane Ethernet interface with a web server running on the host CPU. Only an HTTP web server software is required on the host computer which facilitates integration and set-up.

Full Configuration of Displayed Data and Front Panel LEDs

The displayed data is controlled by writing to an HTML file. Any status or error message available to the CPU can be shown on the front panel.

Suited for Harsh and Mobile Environments

The G233 is designed for -40 to +85°C operating temperature and conformal coated in order to be used also in harsh and mobile environments.
