Remote script download using RC intrinsic function

2 Overview

2.1 General

The remote script download is dependant on the currently active script
within the GR47 having the RC intrinsic function capability written in such
a way that once a CSD data call is received, the RC intrinsic function is
called and the remote script download takes place. Once the script is
down loaded into GR47 memory and all checksums are verified, the GR47
is reset and on completion of the power up routine the new downloaded
script is activated.
It is imperative that the new script downloaded using the over the air
routine also has the RC functionality written into it as once the new script
is activated and running, then without having the RC functionality active,
the script will not be able to be updated again.
The remote download process takes care of script number allocation and
will use whatever script number is not being used by the activated script.
This ensures that the original script is not lost and can be activated again
if the new script is not functioning as expected.
Note.
It is very important that the new script to be downloaded using the remote
download facility has been checked thoroughly for possible bugs or run
time errors. As once the script is downloaded and activated, it is not
possible to gain remote access again if the script has crashed and is not
running.

2.2 Control PC setup

The remote PC will require the latest IDE to be installed and preferably
connected by UART1 to a GSM modem and the script to be downloaded
needs to be open in the main IDE screen.
Select the yellow telephone icon next to the main script download button
in the tools menu. A pop up box will ask for the data telephone number of
the GR47 you are going to download a script to. Enter the number and
select OK and wait for the remote download pop up to appear.
Once the remote download popup appears select download and the script
will be downloaded to the remote device. Progress can be monitored on
the download bar as a percentage to completion. Once the download has
finished, you must select the EXIT button on the download popup which
will reset the remote device and the new script will be run on power up.
