Intertier Voltage (mvolts) - This column indicates the voltages being sent. This screen
displays up to 15 intertiers for the BDS and is used to confirm calibration accuracy. The cell
number is the lower of the two cell numbers across which the intertier is connected (selected
on BDS Setup|Battery|Parameters).
27.10. Communication Error (BDS)
String View > Diagnostics|DCM Comm Error
When communication integrity between the BDS and DCM fails, the Error Counts for the
associated DCM increments, and String Status on the String View screen indicates
"DCM-Comm Error." Error Counts can reach 255 before rolling back to zero.
Check DCM Address area - Click Start to check the DCM address. Using groups of flashes,
the DCM Status LED indicates the string and DCM address for that DCM. The first series of
flashes indicates the string ID. (For example, one flash means string 1, five flashes string 5.)
After a pause, a second series of flashes indicates the DCM ID within that string. After
another pause, two rapid flashes indicate the end of the cycle, which then starts over.
