Forcing a Firmware Load
If you accidentally load an old or incompatible firmware version and find the KAT500 unresponsive, do
the following:
 Switch off the power supply or disconnect the KAT500 from its power supply for at least 30
seconds. The delay is important because the KAT500 microcontroller may continue to function
with very low voltage and current draw so capacitors need time to fully discharge before
continuing.
 In the Utility program, clic
k Close Port
.
 Press and hold the KAT500 front panel
MODE
switch.
 Reconnect the DC power supply.
 Continue to hold the KAT500
MODE
switch until the
MAN
LED begins to blink (about 10
seconds).
 Release the
MODE
switch.
 If the Utility program is running, click
Test Communications.
You should see a status message
indicating that the KAT500 is waiting for firmware load:
 In the Utility program, select
Send Firmware on
the
Firmware
tab.
