CHAPTER 8 SERIAL INTERFACE
Introduction
This chapter describes how to set up the decoder with a serial host. The serial interface connects the decoder
to point-of-sale devices, host computers, or other devices with an available serial port (e.g., com port).
If the host is not listed in
Table 8-2
, refer to the documentation for the host device to set communication
parameters to match the host.
Throughout the programming bar code menus, asterisks (
*
) indicate default values.
NOTE
The decoder uses TTL signal levels, which interface with most system architectures. System architectures
that use RS-232C signal levels require a conversion circuitry.
*Baud Rate 57,600
Feature/Option
*
Indicates Default
NOTE
The serial host type requires proper configuration of the sysconfig lines, and typically requires scanning
bar code menus as part of initial configuration.
Most computer monitors allow scanning the bar codes directly on the screen. When scanning from the
screen, be sure to set the document magnification to a level where you can see the bar code clearly, and
bars and/or spaces are not merging.
CAUTION
The PL3307 wakes from low power mode upon receiving a character. However, the PL3307 does not
process this character or any others it receives during the 7 ms period following wakeup. Wait at least
7 ms after wakeup to send valid characters.
