7.6.4 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 determ-
ine 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>"
