This chapter includes basic information, descriptions of common problems, and steps
to follow when determining which parts to replace in the 1555.

About the 1555

The Sabre 1555 RFID and Bar Code Reader is a dual-purpose device that can scan bar
codes and read and program radio frequency identification (RFID) tags.

There are two models of the 1555:

•

The standard model is powered by an external AC power supply (P/N 070826) and
is connected to a host PC via a stationary reader cable (P/N 3-614032-00).

•

The Portable Data Terminal (PDT) model is powered by a rechargeable battery
pack (P/N 070067) and connected to a host PC via a PDT reader cable
(P/N 3-634032-11).

Each model is available with either a 2.4 GHz or 915 MHz RFID option.
