1 Introduction 1.1 Overview The Flat Panel Transfer Board (FPTB) is intended for prototyping and verification of LVDS and TTL flat panel displays with COM Express systems. The FPTB is equipped with an LVDS-to-TTL converter to allow users to implement TTL displays with COM Express systems that support LVDS only. Onboard PWM circuitry supports backlight control for LVDS and TTL displays. 1.
1.3 Mechanical Drawing Dimensions in mm.
1.4 Applications The FPTB is intended for use in the following situations: • nanoX/Express-BASE → FPTB → Customer’s cable to TTL display: This configuration provides LVDS-to-TTL conversion and backlight control when using an ADLINK reference carrier board with a TTL display. User must provide the cable connection from the FPTB's TTL output and backlight control connectors to the TTL panel inputs.
• Customer carrier (with LVDS output) → Customer’s cable to FPTB → FPTB → Customer’s cable to TTL panel: This configuration provides LVDS-to-TTL conversion and backlight control when using a customer carrier board with a TTL display. User must provide the cable connections from the customer carrier board LVDS output to the FPTB's LVDS input connector and from the FPTB's TTL output and backlight control connectors to the TTL panel inputs.

3 Getting Started The example instructions below describe how to use the FPTB to connect an ADLINK reference carrier board to a TTL display: In this configuration, the FPTB provides LVDS-toTTL conversion and backlight control. The user must provide the cable connection from the FPTB's TTL output and backlight control connectors to the TTL panel inputs.
3.2 LVDS Input to FPTB Use the LVDS-to-LVDS cable that came with the FPTB to connect the LVDS output connector on the ADLINK carrier board (CN6 on nanoX-BASE) to the LVDS input connector on the FPTB (CN4).
3.3 TTL Output to Display Panel Make the appropriate cable to connect the TTL Output Connector (CN5) and Backlight Control Connector (CN8) on the FPTB to the target TTL display panel. 3.4 FPTB Power Connector Connect the Floppy Drive power connector of your power supply to the FPTB Power Connector (CN1). 3.5 Power Up the System Assemble the rest of your system as required and power it on. An example nanoX-BASE system with FPTB connected to a TTL display panel is shown below.
