INTRODUCTION
Description
The Omni™ slot reader can scan and decode most popular bar codes, and/or
read 1, 2, or 3 tracks of magnetic stripe information, depending on the model.
In addition, it has full data editing capabilities.
The Omni can be connected to a single-ended serial device, such as a cash
register, PC, or terminal, through an RS-232 serial port or a USB port, de-
pending on the reader interface.
This unit is fully programmable via keystroke commands. The data can be
formatted with preamble/postamble and terminator characters to match the
format expected by the host. The programing codes are the same for both RS-
232 and USB/RS-232 units. Please see Appendix E for details.
Power is obtained from a separate power supply module when the unit is con-
figured as an RS-232 device. Power, when the reader is connected via a USB
port, is obtained from the host.
