CF Card Replacement:
CAUTION: Due to the large variability of CF cards available on the world market and the
resulting problems with compatibility due to memory layout, signal structuring and power
requirements, REF TEK cannot guarantee a CF card will work in a REFTEK data recorder
unless it is sold through REFTEK itself. REFTEK ensures compatibility through
communications with CF manufacturers and rigorous in -house testing. Some CF
manufacturers refuse to provide adequate information or factory controls to ensure that the
product being sold today is the same as the product sold earlier under the same part
number. CF cards not purchased from REFTEK may work at one temperature but not at
another, or may fail all together.
Software Version:
Current software and documentation is available on our web site. Some early units may require
hardware modifications to use the latest software. Contact REF TEK if you have any queries on
the compatibility of your unit(s) and the current software release.
Firmware Update:
To update firmware from the FTP site

To Update Firmware:
Updating firmware in a 130-SMHR-C requires the presence of a firmware file on an installed
Compact Flash device.
1. On power-up, the 130-SMHR-C checks the Compact Flash for the presence of 'main.s3' in the root
directory.
2. If the 'main.s3' file is present on the Compact Flash, the 130-SMHR-C:
Reads the file.
DELETES the file.
Re-programs the internal flash memory.
Note: User parameters stored in SROM using the WP command will be erased when a
firmware update is performed.
CAUTION: DAS power must be above 10.0V to update the firmware.
DO NOT DISTURB THE UNIT DURING THIS PROCESS.
