appear to be
not active
Problem
active
Reason
Power is not applied or is less than 5V
DATA Selector switch was not set to the STK511
position when power was applied
Receiver in permanent sleep mode because Sleep
mode of all 1s selected in OPMODE register
Receiver Application Board rotated 180° when mounted
on the STK512 Interface Board
Power not applied
Corresponding DIP Switch bit(s) not set
Bias resistor(s) damaged
Incorrect firmware loaded into the STK512 Interface
Board where I/O port of the onboard microcontroller
programmed to logic high
Power supplied is too low
DATA Selector switch was not set to the STK511
position when Configure button pressed
STK512 Interface Board firmware has become
corrupted
Registers may be programming correctly with no visible
signs of change Some external source may be holding
the Data line low
Receiver Application Board rotated 180° when mounted
on the STK512 Interface Board
Solution
Verify that 5V is supplied to the Receiver Application
Board via on-board pins or through the STK512 Interface
Board connection to the STK 500 (VTG jumper).
Set DATA Selector switch to STK511 and re-apply 5V
supply
Select different polling rate and re-program OPMODE
register
Verify that Receiver Application Board signal test points
are placed toward the DIP switches.
Verify that Power is supplied to the STK512 Interface
Board through either the Receiver Application Board or
the STK500 Board (VTG jumper).
Set the corresponding bit(s) to ON on the DIP Switch for
that register.
Replace the corresponding bias resistor(s) on the back of
the STK512 Interface Board with 1 k
Reload the STK512 Interface Board Firmware as
described in Section 2.2.
Verify that the power being supplied is 5V
Set DATA Selector switch to STK512 and re-press button
Reload the STK512 Interface Board Firmware as
described in Section 2.2.
Monitor the Data Test point with an oscilloscope to check
for presence of the acknowledge bit.
Verify that Receiver Application Board signal test points
are toward the DIP switches.
