UPC-E1 Preamble
Parameter # 24h
Preamble characters are part of the UPC symbol, and include Country Code and System Character. There are three options for
transmitting a UPC-E1 preamble to the host device: transmit System Character only, transmit System Character and Country Code (“0”
for USA), and transmit no preamble. Select the appropriate option to match the host system.
Convert UPC-E to UPC-A
Parameter # 25h
Enable this to convert UPC-E (zero suppressed) decoded data to UPC-A format before transmission. After conversion, the data follows
UPC-A format and is affected by UPC-A programming selections (e.g., Preamble, Check Digit).
When disabled, UPC-E decoded data is transmitted as UPC-E data, without conversion.
