8. Send the SOFTLOADSREC command to the G-III Reference Receiver through the Data port
(J02).
9. Verify that the receiver has responded with <OK.
10. Repeat steps 6 to 9 until all of the S-Records in the hex file have been read and sent to the G-III
Reference Receiver.
11. Close the firmware update hex file.
A script should be created in a text editor and then run using Python or another similar utility. An example
Python script is shown below. The DataPortIP, UDPPort, and SWFileName may need to be updated
before executing the script to reflect the receiver configuration and file name of the .hex file. Note that using
this sample script with a 13 MB .hex file will take approximately 2 minutes.
import socket
import time
# Default G-III IP address and UDP Port
DataPortIP = '192.168.0.10'
UDPPort = 3000
# File name of the .hex file to load one SREC at a time.
SWFileName = 'AW3MM0000RN0000.hex'
# Create the UDP socket to connect to the G-III
s = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
# Default IP address and UDP port to connect to the G-III
s.connect((DataPortIP, UDPPort))
# Set the timeout to 1 second to receive data
s.settimeout(1)
# Variable to hold the SOFTLOADSREC command to be sent to the G-III
scmd = ''
# Variable to hold the response from the receiver
response = ''
# Variable to detect loading failures
LoadingFailure = False
# Print message to screen
print 'Softloading G-III.
# Open the G-III SW .hex file, read in one line at a time
with open(SWFileName, 'r') as hexSWfile:
for line in hexSWfile:
if LoadingFailure == True:
# Prepare the SREC line to be sent
scmd = 'SOFTLOADSREC ' + line
132
print "Loading Failure."
