Connect the ControlWave EFM's Comm Port 1 to a PC using a
3.
null modem cable.
4.
If the SCM's mode switch has a Run/Remote/Local switch, set it
as follows. Set both SW1-1 and SW1-2 to the right (open)
operation or both to the left (closed).
5.
Start the PC's HyperTerminal program (at 115.2 kbaud) and
generate a receive using the 1KX-Modem protocol. Save the
resulting core updump in a file so you can forward it later to the
technical support group.
By setting the CPU module switches SW2-1 and SW2-4 both off before
the EFM fails, you prevent the EFM from automatically recovering
from the failure and enable it to wait for you to take a core updump.
Once you complete the core updump, set the CPU module's switch
SW2-1 to ON (Watchdog Enabled) and SW2-4 to OFF (Core Updump
Disabled).
Additionally, for the SCM mode switch, set switch SW1-1 to open
(right) and SW1-2 to closed (left).
With these switches set, power up the EFM and recommence standard
operations.
