Each LogTag data logger can be identified via a unique serial number. This number allows LogTag to identify production information, as well as giving you, the client, the ability to create records that are unique to each logger.
Over the years we have introduced several different formats of serial numbers. These numbers can be found on the front or rear of the loggers, typically together with a Code-128 barcode that represents this serial number, preceded by "S/N:".
10-digit numbers
10-digit serial numbers are typically used for our older 3-pin models such as TRIX-8 and SRIC-4. They consist solely of digits and are typically found as part of the model label on the rear of the product.
The serial number contains limited information about the model and an index number.
12-character serial numbers
12-character serial numbers were introduced to allow better integration of the loggers with LogTag Online, as an included verification code prevents loggers to be incorrectly registered.
They were used particularly with our WiFi model, but have now transitioned to most loggers. The serial number has 3 distinctive sections.
- 4-character identification code
This consists of alpha-numeric characters and contains information about the model. - 6-digit index number
- 2-character verification code
These two alpha-numeric characters represent a checksum and are required for LogTag Online to verify the preceding 10 characters have been entered correctly.
The actual serial number is still only a 10-character number; in fact, the logger electronically only stores the 10 characters and calculates the verification code when needed.
To make this more obvious, we will successively introduce a slight variation of this label that clearly identifies the verification code.
Note that the verification code is always present in the barcode.
When you enter the serial number into LogTag Online, enter all serial number (S/N:) characters, followed directly by the Verification code (VC:)characters, to make a 12-character number.
15-digit serial numbers
15 digit serial numbers are used on the EV4-GEO exclusively, and represent the device's IMEI (International Mobile Equipment Identity) number.
