Chapter 4 - Configuration Command Reference TLC 39 TLC 39 is a "composite" symbology designed for the Telecommunications Industry. TLC 39 combines a Code 39 symbol, encoding a part number (for items such as plug-in boards at central switching stations) with a "linked" MicroPDF417 symbol encoding a serial number and other optional information. The first 6 characters must be numeric and include the ECI number. The 7th character is a delimiter between the linear data portion and the composite data portion, typically a comma, but other delimiters are allowed. The next piece of data is a mandatory unique Serial Number. There can be other data fields after the Serial Number, usually either AppIDs or DataIDs, which are governed by whether or not there are alpha characters in the serial number. Country Of Origin is another typical data field that is included in this symbology. Trigger Mode Trigger mode allows you to set different types of triggering for the scanner. Mode Continuous/ Edge Level Description When you press the Scan button, the red scanner beam turns and stays on. When you press the Scan button a second time, the scanner turns off. Simply releasing the button does not turn off the scanner. When you press the Scan button, the red scanner beam turns on and stays on until you release the Scan button or until the SF51 successfully decodes a bar code. When you scan a data bar code, data transmission may be slow if there is interference with Bluetooth communications, or if the SF51 is too far from the host device. While the SF51 is waiting, the scanner beam blinks. During this time, you can scan configuration bar codes but not data bar codes. When the SF51 receives acknowledgement from the host, the scanner turns off, and the SF51 beeps. SF51 Cordless Scanner User's Guide 49
