DEMO BOARD SETTING
Figures 8 and 9 show the AMT-DMBD board operational setting menus. The buttons function as follows:
• NEXT
: go to the next menu
• HEX/DEC
: select the position display to be HEX or DECIMAL. The encoder always sends binary data but the
AMT-DMBD translates it to HEX or DECIMAL for display on the LCD.
• NORM/FAST
: select the encoder reading method to be normal or FAST. For normal reading the full position is
read, for FAST reading only the lower 8 bits are read and the AMT-DMBD board tracks the
position. This setting is to allow a logic analyzer to view the read protocol on the SPI lines.
• EXIT
: return to the main menu
• NEXT
: returns eeprom XX location value
• XX
: displayed eeprom value (swith has no functionality)
SETUP
The AMT-DMBD board is powered by the USB which will work even when the drivers are not installed. To use the
USB port for controlling and reading the ABS encoder, the USB drivers must be installed. When the drivers are in-
stalled the USB port behaves as a high speed serial port and is mapped to a com port under Windows.
INSTALLING DRIVERS
When the encoder is plugged into the PC the first time, Windows should attempt to load the driver. The drivers are
on Windows update so you can allow Windows to get them from the network.
These are FTDI VCP drivers so they can also be downloaded and upgrades will be available
from http://www.ftdichip.com/Drivers/VCP.htm
