The configuration on the SSI logger consists of several text files which can be edited on a PC. These need to be extracted from the logger, edited and then reinstated. It is possible to “brick” the logger if these files are edited incorrectly.
Required equipment:
- Blank USB stick
- PC (to edit configuration)
Saving Configuration to USB
Remove the USB to serial converter and insert the USB stick into the logger.
Navigate to the configuration menu:
Enter 12345 as the pass code:
Select “Save Configuration To USB”:
The logger will write the configuration to the USB stick:
When it’s finished, click “OK”
Updating the configuration
The USB stick will contain a folder named config_XXXX where XXXX contains the logger’s serial number:
It will contain several files, as per the example below:
Before editing the configuration, take a backup copy!
The “init.txt” file contains the logger’s start-up instructions, which will include a line as below:
ssi uart1=/dev/ttyUSB0 uart2=/dev/ttyUSB1 cfg=scripts/STPANCB.xml
This tells the logger that the file STPANCB.xml contains the SSI configuration for this logger.
Load the relevant ssi configuration file (i.e. STPANCB.xml in this case) into a text editor (notepad will not suffice, use wordpad or (recommended) notepad++).
You need to change the expected identifier to agree with the correct SSI Interlocking value.
This is at the end of the file, as in this example:
The value should be a positive integer from 1 to 63.
You may find configurations which contain “-1” which has been used as a placeholder.
Save the file back to the USB stick.
Loading Configuration from USB
First insert the USB stick into the logger.
Navigate to the configuration menu:
Enter 12345 as the pass code:
Select "Load Configuration From USB":
Confirm loading of the new configuration:
The logger MUST be restarted in order that the new configuration is used.
Wait for the logger to restart.
