Firmware Updates
The Winloader utility is used to update the firmware on an ECM850.
The current firmware version of the ECM850 may be obtained using either the Machine
Edition programmer (Online Commands->Show Status->Details),
or the module’s
Command Line Interface node command.
Connect Winloader to the RX3i CPU’s serial port and specify the desired target module by
its Rack/Slot location. The CPU must be placed in STOP/OUTPUTS DISABLED mode to
update module firmware. The Winloader utility displays the update completion status as
the update progresses. When the update has completed, the ECM850 will restart,
completing the update and activating the updated firmware.

Time Synchronization with the RX3i CPU
The internal clock value of an ECM850 is displayed in Command Line Interface commands,
and it is used to timestamp entries in the ECM850 Local Fault Log as they occur.
The ECM850’s internal clock is synchronized with
the RX3i CPU clock whenever the ECM850
is:
•
powered up, or
•
hot-inserted, or
•
reset with the Reset pushbutton or on command from the Command Line Interface.
Storing hardware configuration to the ECM850 does not cause clock synchronization.
If the CPU’s time i
s changed after the ECM850 synchronizes its own internal clock, the
ECM850’s internal clock is not automatically synchronized until the ECM850 is again
powered up, hot-inserted, or reset.
The ECM850’s internal clock may be set from the Command Line Interface at any time, using
the time command.
