BDS Diagnostics
27-1
27. BDS Diagnostics
String View > Diagnostics|Item
The diagnostics are used for production testing, but may help troubleshoot a hardware failure in
the field. Select Diagnostics from String View. The computer must be connected to a BDS and
Communication Status at screen bottom must show Response OK.
27.1. Rebooting and Power Up Diagnostics (BDS)
String View > Setup|Reboot Firmware
To reboot the BDS from the Data Manager, select Reboot Firmware. This does a "warm
reset" of the BDS. At power-up, the unit performs diagnostics for about two minutes. If a
failure occurs, identify the failing parameters by using the Self Test diagnostic.
27.2. Self Test (BDS)
String View > Diagnostics|Self Test
Self Test reads BDS and DCM status registers and displays the parameter status on the
Diagnostics dialog box. These parameters are tested only at BDS power-up. If an update is
needed, cycle the power to the BDS or reboot by selecting Setup|Reboot Firmware. To open
Self Test Diagnostics, select Diagnostics|Self Test.
Figure 123. Diagnostics - Self Test (BDS)
Items in the Self Test Diagnostics box are described below alphabetically. If available, click
the left or right arrows to view settings for other DCM units.
A/D (DCM) - Reads and confirms the A/D converter reference voltage is within
specification.
Code Space (DCM) - Displays the memory type from which the firmware is running.
Typically, this is the PROM, but the system can upload a new version to Flash memory.
