Firmware Upgrade
Instructions

5.1 Introduction

The following is a short tutorial on how to upgrade the RSR GNSS Transcoder firmware. Please
follow the instructions in order to prevent corrupting the units' Flash, which may require reflashing
at the factory.
With some practice, the entire Flash upgrade can be done in less than two minutes, even though the
following seems like a fairly long list of instructions.

5.2 ISP Flash Loader Utility Installation

Jackson Labs Technologies, Inc. recommends using the Flash Magic utility to upgrade the contents
of Flash memory on the RSR GNSS Transcoder. It is available for download on the Flash Magic
website:
http://www.flashmagictool.com/
Follow the directions given on the website for installing the utility on your computer.
Note: The Philips LPC2000 utility that is used on other Jackson Labs Technologies, Inc. products
will not support the newer LPC18S37 processor used on this product.

5.3 Putting the PCB into In-Circuit Programming (ISP) mode

Momentarily short-out pins 1 and 2 of ISP#/RESET# header J3 using a jumper wire or other
conductive material (tweezers etc.) during power-on (See
remain off, indicating the unit is properly placed into ISP mode. If the LED's light up after power-on,
the unit is not in ISP mode. If the unit is in the optional IP67 enclosure, then the ISP# pin is accessible
through the DB-15 connector, Pin 6.
