20 Duet ™ Scanner
Connecting the Scanner
The Duet scanner connects to the store host terminal via an interface
cable. The cable connects to the scanner with a modular connector and
to the host terminal with the connector required by the host (RS-232,
OCIA, Keyboard Wedge, Wand or IBM POS).
DC power to the scanner is supplied by one of two methods:
1. From the host terminal (Power-Off-Terminal)
through a special cable that carries both data and DC
power.
2. From an optional AC/DC power supply that pro-
vides DC power, either through the side of a
connector, or connected to a special connector
attached to the interface cable.
Figure 11 shows how to connect the scanner to the store host termi-
nal. The type of DC power connector depends on your existing store
host terminal.
Power-Up Procedure
The system power-up procedure may vary depending on the require-
ments of your Point-of-Sale (POS) system. Always power-down
(switch off) all equipment prior to connecting cables. Check with
your system supervisor and/or refer to the terminal operator's
manual for proper power-down and power-up procedures for your
system. To connect the scanner:
Power-Off-Terminal (P.O.T.)
1. Connect the interface cable to the scanner.
2. Connect the interface cable to the host terminal.
Power-up the system and scan a few items to verify that data is prop-
erly communicated between the scanner and your POS terminal.
