Product Date Code

The product date code for the IND570xx terminal can be found on the serial data plate on the top of
both the panel-mount and harsh enclosures.
The serial number will begin with a letter and a number (for example B612000371). The letter
represents the first three digits of the year per the date code chart in Figure 1-1 (the letter "B" in our
example represents "201x") and the number is the unit's digit of the year (the number "6" in our
example). So, "B6" decodes to the year 2016.
