Dual Interface Programming, continued
The 3400 is compatible with a wide range of terminals in
the primary (or single) interface mode. (Primary terminal
selection programming is found on page 2–11.)
Secondary interface is designed to support a limited set
of interfaces common to portable data terminals. These
interfaces include:
• Hand Held Laser Emulation (HHLC)
• Wand Emulation, Code 39
• Wand Emulation, Same Code
• RS–232 TTL.
The scanner must be programmed for secondary
interface, just as it must be for primary interface. To
program the 3400 for secondary interface, follow the
steps below.
(Dual Interface single scan programming
codes on the following page.)
➊ While the scanner is connected to the primary terminal
interface, scan one of the single bar codes to enable the
secondary interface.
Note: ENTER and EXIT bar codes are not needed for
Dual Interface.
➋ Disconnect the primary interface cable from the scanner
and attach the secondary interface cable to the scanner.
➌ Attach the secondary interface cable to the secondary
terminal and power up the terminal.
➍ Program the desired programmable selections for the
secondary interface. These selections include:
Prefix/Suffix Reread Delay
Buffer Scans Wand Emulation Polarity
Trigger Mode Wand Emulation Transmission Rate
Symbology selections (including EAN ISBN).
3400–X3 and 3400–18 units do not support Dual Interface.
