CV 30
ERROR
INFORMATION
Description
Contains manufacturer defined error codes and provides feedback in the event an operational
failure occurred within the DSD:
bit 7 bit 0
I2C ROMCS EEROM WDOG
Bit 0: WDOG, Watch Dog Timer Reset
0 = System normal.
1 = Watchdog time-out occurred.
Bit 1: EEROM, EEROM Data Corrupted
0 = System normal.
1 = CV Data in EEROM has become corrupted. All CVs will be reset
to default values.
Bit 2: ROMCS, Program Checksum Failure
0 = System Normal
1 = Program Checksum Test Failed
Bit 3: I2C, I2C Bus Acknowledge Failure
0 = System Normal
1 = No acknowledge detected from I2C bus.
If the DSD is operating properly, all error bits should read as 0. If an error is detected, it is usually a good idea
to reset the decoder (tip the locomotive) and verify the error has recurred.
A WDOG error usually occurs when the DSD experiences a large electrical glitch or static electricity discharge.
It is not cause for concern unless it occurs frequently (several times within an operating session) in which case
you should contact the factory for further assistance.
An EEROM error indicates that the CV data somehow became corrupted. If such an event occurs, the DSD will
reset all CV data to the default settings, flash both headlights for 30 seconds, and resume normal operation. If
this occurs, reprogram the CVs as needed. If the problem recurs repeatedly, this could indicate a problem with
the DSD. Contact the factory for further assistance. This bit can also be used to deliberately reset all other CV
values to their default values with a single operation. This is done by programming CV 30 with 02 in service
mode and turning power to the DSD off and back on.
Note: This bit can be programmed only in service mode.
Writing any data value during operations mode will clear all error bits to 0.
A ROMCS error indicates a hardware failure has occurred and will usually be accompanied by strange sound-
ing noises. Contact the factory for further assistance.
An I2C error also indicates a hardware failure and the DSD will be unable to remember any changes made to
the CV settings. Contact the factory for further assistance.
