Enabling the Secondary Interface

You can temporarily disable the secondary interface, but still retain the second-
ary interface settings in the imager’s memory by scanning the Disable bar code
below. To re-enable the secondary interface, scan the Enable bar code.

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. If you want to change the
RS-232 settings, refer to the
Connecting the Scanner with RS-232 Serial Port
section on pages 2-8 to 2-11.
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 symbol
-
ogies to Code 39. The Same Code Format transmits U.P.C., 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.
The
Code 39 Format
bar code below sets the terminal ID to 61, and the
Same
Code Format
bar code sets the terminal ID to 64.
