If the letter or number is displayed in the response message, the option is available. 
If the letter/number is not displayed, the option is not available. Table 1.3 lists the 
available options when the $PASHQ,SCRN,8 command is submitted.
Memory Options
The amount of data the sensor can retain depends upon the amount of memory that is 
installed. You can verify the amount of memory by viewing the rear of the Sensor and 
noting the part number which is located on a sticker. The part number should have a 
dash at the end followed by two digits. These two digits represent the memory option 
which has been loaded into the Zensor. Table 1.4 lists the memory options which are 
available.
