8-2 Troubleshooting 937696 DBK70 User’s Manual
Special Notice for LogBook Users
This notice applies to the use of a DBK70 with a LogBook.
Symptom - LogView reads all DBK70 channels as Channel 0.
Solution - Should this problem occur, it can be resolved by taking the simple steps provided below.
Note that both hardware-related and software-related steps must be taken to ensure that all
channels will read correctly.
Hardware Related Steps
1. With power off to the DBK70, remove cover plate.
2. Check the DBK70 board to see if there is a header labeled "J2."
Refer to the following figure for location.
J2 Location Reference
3. If the “J2” header is present, verify that it is free of a jumper.
If a jumper is present, remove it.
Note: Most DBK70 modules shipped after September 1, 2001 do not have the “J2” header.
4. Replace the cover plate.
Regarding Configuration in LogView
1. When you configure the list of expansion modules in LogView, use the setting "DBK13 Analog
Multiplexer" instead of "DBK70 Vehicle Bus Interface." This is done when configuring the base
channel to which the DBK70 is assigned. Refer to your LogBook User’s Manual (461-0901) if
needed.
2. Make sure that the range selected for each channel is the default setting of
-10.0 to +10.0 volts. Other range settings will produce incorrect results.
This completes the corrective action.
