RW 420 Vehicle Cradle Installation Guide
Introduction
NOTE: Zebra Technologies Corporation is not liable for personal injury or
damage to any equipment caused by the improper installation of this
equipment to any power source.
This equipment should be installed in accordance with this installation
guide and under the supervision of properly trained and qualified person-
nel.
The RW 420 Vehicle Cradle allows use of the Zebra
®
RW 420
Receipt Printer in a vehicle. The Vehicle Cradle will provide com-
munications capabilities and intelligent battery charging for a
RW 420 Printer while still maintaining all of Printer’s functionality.
Power for the Printer and the Vehicle Cradle’s built in charger is
provided by the vehicle’s electrical system.
The Vehicle Cradle is offered with two input power connection
options:
• A power cable which can be plugged into an automotive ve-
hicle’s cigarette lighter socket.
• An unterminated cable which must be wired into the vehi-
cle’s power system (9-30 VDC)
Both versions of the Vehicle Cradle offer an external RS232C
communications port to allow connection of the printer to either a
PC or a data terminal while still mounted in the Vehicle Cradle.
An optional mounting arm provides the ability to locate the
Printer and Vehicle Cradle in a variety of positions and mounting
locations to enhance its accessibility and ease of use.
The following instructions detail the installation and use of the
RW 420 Vehicle Cradle. Following these instructions closely will
ensure safe, reliable performance of the RW 420 Printer when in-
stalled in the Cradle.
The Printer runs off its own battery, which is monitored and
charged by circuitry within the Cradle.
The user should always refer to the RW 420 Users Guide for com-
plete information on using the Printer.
It is important that the vehicle’s electrical system function prop-
erly. The vehicle’s charging circuit must work properly and ve-
hicle-generated electrical “noise” must be minimized and within
specifications.
The vehicle charging circuit must neither undercharge nor over-
charge the vehicle battery. Defective ignition wiring, damaged in-
sulation, or faulty vehicle electrical components can cause excess
electrical noise severe enough to defeat the electrical filtering that
is built into the Cradle and the Printer.
