WRITE
To write to the new board, after reading from the original board, clip the test clip to the new
NVM chip and press the write key once. When the JIG has completed the write, the yellow
LED will light.
ERROR INDICATION
If the JIG encounters a problem with communication to the NVM chip (i.e. no
acknowledgement on the line that a chip is there), the power LED will blink.
If there is an error indication ensure that the connector is attached properly.
That the Microprocessor on the board is disabled.
Try added or subtracting the pullup resistors on pins 3 and 4 of the DIP switch.
Turn the unit on and then back off again and try reading again.
♦
This error will occur when the NVM has not acknowledged any of the addresses for our
NVMs. These addresses range from A0 hex to AE hex.
♦
When communication has been interrupted between the JIG and NVM
♦
And when the data does not compare properly between the JIG and Target NVM.
AFTER GETTING AN ERROR INDICATION
Press one of the keys once for a duration of approximately second. This will take you out of
the blinking RED LED mode and a solid RED LED will again light. At this point you are back at
the starting point and may press either Write or Read buttons.
POWER DOWN
If the unit is powered for a period of time equal or greater than 5 minutes the JIG will power
down. By turning the unit off and then back on again, you may restart your process.
