AMT-DMBD Demo Board
The AMT-DMBD Demo Board is designed for testing and configuring the AMT 203 Absolute Encoder over the 10 pin
encoder connector using the SPI link. The board has a 2 line 16 character LCD display and 3 pushbuttons for use in
standalone operation. In addition there is a USB 2.0 interface and drivers are available from WINDOWS UPDATE for
XP86, XP64 and Vista (32 and 64 bit).
The USB connector provides power whether or not the driver is installed on the host PC. If the board is first
plugged into the USB connector the AMT-DMBD will attempt to connect to an encoder and the LCD will show the
current position in hexadecimal format (as shown in Figure 1). The AMT 203 connector is a 10 pin connector that
has a polarization arrow on the topside as shown. This connector and the ABS encoder may be plugged in before
or after the DEMO BOARD is powered up. The Activity LED (D1) will flash with a 1 second period when the board is
powered. This signifies the internal timer interrupt is working and the program is running.
