9. OEM FUNCTIONS
As an option the portable reader allows other companies to incorporate their own application
software into the device. These companies are referred to as Original Equipment
Manufacturers (OEMs).
To make it easier for OEM's to develop applications, the portable reader has several
functions that allow OEM's to access tag data read by the portable reader and to send OEM-
application generated data to other computer systems as a file transfer to an FTP server or
as a file attachment to an email.
9.1. Accessing Tag Data
When the portable reader reads a tag or barcode it writes a record into a text file called "tag
data.txt". This file is located in a folder designated by the user in the OEM Setup function
(see Paragraph 5.16).
The Tag Data file is a text file that has an individual record for each tag read. Each record is
terminated with a carriage return character (hex 0D) and line feed character (hex 0A). All
fields within the record are separated by commas.
There are four types of records in the Tag Data file. These are:
Rail vehicle tag
Track
