Troubleshooting: GE T2100 Treadmill Diagnostic Utility (TDU)
Host Synchronized Mode
When the GE T2100 Treadmill receives a valid date and time from a host
device, such as CASE v6 or the TDU, the GE T2100 Treadmill will enter
the Host Synchronized Mode. The GE T2100 Treadmill will stay in this
mode until power is lost to the GE T2100 Treadmill. While in this mode,
the system keeps track of the number of seconds that pass since the date
and time were received from the host. When an event is logged while the
system is in this mode, the event will be date and time stamped with a
date and time relative to what was sent by the host.
NOTE
When the GE T2100 Treadmill enters the Host Synchronized Mode,
the "Date and Time Set" event is stored with a date and time relative
to the power-up date and time. This event can be used to see how the
following events with actual dates and times chronologically fit in
regards to the power-up date and time. In addition, the date and time
of the events can be used to match up with specific stress tests.
