Chapter 9: Example: Scanner Converter Board
Overview
Psion Teklogix WORKABOUT PRO HDK User Manual 91
9.1 Overview
Psion Teklogix provides a scanner converter board in WORKABOUT PRO units that incorporate
a scanner. This board is attached to the scan engine, and differs depending on the installed scanner.
At a minimum, the scanner board physically connects the supply voltages and signal lines pro-
vided by the scanner flex to the scanner device. Different scanner devices require different
regulation and switching.
This chapter describes the scanner converter board used with the SE1223 scanner, and its interface
to the WORKABOUT PRO main logic board.
9.2 Example Scanner Boards
The schematics for two sample scanner boards are included in the HDK. Both boards work with
the SE1223 scan engine. One provides serial output: The other provides USB output. These
boards work with both the WORKABOUT PRO and the WORKABOUT PRO 2nd.
Generation computers.
9.2.1 Serial Scanner Board
This board can be configured for use either with Symbol scan engines, or with Intermec
scan engines.
This scanner board incorporates AND-gate buffers on the signal lines: a 74HCT08 buffers
outbound signals, and a 74LVC08 buffers inbound signals.
The scanner board can be configured for the Symbol or Intermec scan engines by providing
zero-ohm resistors (jumpers) in locations according to the following table:
