6 Secondary Interface
By switching interface cables, the NCR RealScan 7837 High-Performance
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 NCR RealScan 7837 High-Per-
formance Scanner-1110-9090.
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 symbol-
ogies 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.
Note for the 7837-1200-9090 model: When the 7837-1200-9090 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.
