The PSW firmware can be upgraded using the
USB A port on the front panel.
Note
Ensure the load is not connected.
Ensure the output is off.

Insert a USB Flash Drive into the USB port on
front panel of the PSW.
The USB drive should include the
gw_psx
and
tcmd.tst
files in the root directory
(USB\:).
For units with firmware version V 1.12 or
below, a folder named
“

gw_psx
file should be copied
to both the root directory and
to the “

”
folder before proceeding with the firmware
update procedure.
For firmware versions after V1.12, only the
root directory needs to contain the
gw_psx
file.
