TROUBLE SHOOTNG
If you have purchased the assembled Finger Board, it is fully tested and operational before shipping.
If it fails to function properly, inspect the board for obvious physical damage. If there is damage,
please contact us for replacement.
The most common problems are improperly configured communications parameters or attempting to
use the wrong COM port on the PC. Verify that your communications port is working by substituting a
known good serial device or by doing a loopback diagnostic. Also check your power source. The
input voltage should not fall below 7 volts DC.
For kits,
Check for +5VCC voltage on header JP16.
Check and make sure all components are installed and properly orientated.
Check all resistor and capacitor values.
Check LED polarity.
Check IC positions.
Check Tantalum capacitor polarities.
Check for shorts.
Check for cold solder joints.
Problems communicating, remove LED D1, it’s probably in backwards.
If not using the optional SRAM battery backed feature, makes sure solder pad J5 is bridged.
