APPENDIX B
FIRMWARE PROGRAMMING
On occasion it may be necessary to update the internal software of the analyzer,
also known as the firmware. The firmware can be updated in the field with the use
of a computer connected to the ENERAC through the serial port. Firmware updates
can be downloaded from the ENERAC website: www.enerac.com, or requested on
a disk from the factory. The current firmware version is displayed on the second
status screen.
Updating the firmware
1. Open the battery compartment of the ENERAC and locate the programming
switches behind the batteries on the right side. There are 5 miniature slide
switches on a red block. See figure 4, page 46.
2. Connect the serial port of the computer to the ENERAC. Run the firmware
update. The program will backup the ENERAC’s settings.
3. When prompted, toggle all the switches on. The firmware will now be
reprogrammed. This will take 2-3 minutes.
4. When prompted, toggle all the switches off and replace the batteries and
cover. The ENERAC’s settings will be restored.
5. Autozero the analyzer. Check the span calibration of all sensors.
