11.7.4 SoftLoad Update Method
This section describes the sequence of commands that are issued to the receiver when updating using a
*.shex file.
The response for each command must be processed before sending the next command so as to
determine if the command was accepted or rejected, and to wait for the receiver to complete the
operation. Responses to SoftLoad commands are guaranteed to be output from the receiver within a
specific time, which varies by command. Refer to specific SoftLoad command
for more information on responses and the timeout values for SoftLoad
commands.
1. Open a connection to any port on the receiver (COM, USB or ICOM) with the input and output
INTERFACEMODE set to NOVATEL.
2. Request the SOFTLOADSTATUS log using the following command:
LOG SOFTLOADSTATUSA ONCHANGED
3. Initialize SoftLoad with a
SOFTLOADRESET
command. This command stops all tracking on the receiver
to ensure sufficient memory is available for the loading process. An RXSTATUSEVENTA log reports a
SoftLoad In Progress status.
4. Open the *.shex firmware file.
5. Read each line of the *.shex firmware file.
a. Send S0, S5 and S7 S-Records directly to the receiver using the
SOFTLOADSREC
command. The
S-Record must be enclosed in quotation marks:
SOFTLOADSREC "<S-RECORD>"
Data within S0 records can also be sent to the receiver by converting them to
SOFTLOADSETUP
