6 Secondary Interface By switching interface cables, the 3800/3900 scanner can communicate with a portable data terminal (secondary interface), in addition to the host terminal (primary interface). Note: Secondary interfaces do not apply to the 3800XX-15. The secondary interface can be programmed at any time. Secondary Code 39 Wand Emulation In Wand Emulation mode, the scanner decodes the bar code then sends data in the same format as a wand scanner. The Code 39 Format converts all symbologies to Code 39. The Same Code Format transmits UPC, EAN, Code 128 and Interleaved 2 of 5 without any changes, but converts all other symbologies to Code 39. These codes set the transmission rate to 25 inches per second and the output polarity to black, high. Default = Code 39 Format. * Wand Emulation Code 39 Format Wand Emulation Same Code Format Note for the 3800PDF model: When the 3800PDF interface is set to wand emulation, all PDF417 bar code data is transmitted as Code 128. Data from other symbologies follow the rules described above. Secondary RS-232 Connection All communication parameters between the scanner and terminal must match for correct data transfer through the serial port using RS-232 protocol. RS-232 programmable selections are used by both the primary and secondary interfaces. Changing an RS-232 parameter (e.g., baud rate or parity), while in primary or secondary mode will affect both interfaces. RS-232 Interface 3800/3900 User's Guide 6 - 1
