Introduction

Symbol Technologies’ Vehicular Radio Computers (VRC) 4000

series are PC-compatible computers ruggedized to withstand

the physical shock and vibration extremes of harsh industrial

environments. All VRC systems provide a touchscreen, full

VGA display (either electrol uminescent or color LCD), multi ple

network options, and full I/O capability. Each VRC system is

fully PC-compatib le with the MS-DOS Versions 3.3 thr ough 6.22,

Windows 3.1, Windows 95, and Windows NT operating

systems. There are two versions of the VRC: the VRC 4000 and

the VRC 4040. Each of these versions are available with option s

such as additional memory, operating systems, and network

configurations.

VRC 4000

The VRC 4000 is designed for fixed-mount applications. It is

powered by a standard 110 VAC o u tlet via a plug-in pow er

supply. It is hard-wired into the local area network (LAN).

Standard Ethernet or Token Ring hard-wired LAN connections

are supported.

VRC 4040

The VRC 4040 is designed for vehicular-mounted applications

such as those on forklifts, hysters, and motorized pallets. It is

powered from the vehicle’s el ectrical system (battery) through a

choice of two power converters. It uses Symbol’s Spectrum24

2.4 GHz spread-spectrum radio link to communicate with radio

frequency (RF) netw ork access po ints har d-wir ed into t he LAN.

Antenna options include patch and ‘rubber duck’ types.

Set-Up

To set up your equipment, first unpack your terminal and
accessories, and ensure that the parts shipped match the parts
ordered. Keep the shipping container and packing material in
case you need to return your computer for repair at a later date.

The VRC is factory-equi pped with a network interfac e and the
appropriate network software for communicating with the
network. The network ports on the VRC use different connectors
for each type of ne twork. For Token Ring connections, a DB9
connector is used. For Ethernet connections, an RJ-45 connector
is used. For wireless network communications, an FCC
mandated, non-stand ard RF antenna connector is prov ided.

Note: The VRC 4040 uses Spectrum24 2.4 GHz spread-

spectrum radio link to communicate with (RF) net­work access points hard-wir ed into the LAN. These
access points must be set up before the terminal can
communicate with the host. Refer to the Access Point
User Documentation for detailed ins truc tions on se t­ting up the access points.

Mounting the Bracket Assemblies

The VRC 4000 can be mounted almost anywhere that is
convenient to the operator. The mounting location must be near
a standard 1 10 VAC electrical outlet, and there must be sufficient
space below the unit for cable access to the rear panel, which
faces downward when the unit is wall-mounted. Secure the
mounting bracket to a wall prior to attaching the VRC 4000 to
the bracket.

The VRC 4040 mounts to a forklift or other vehicle with a custom
bracket assembly. Operating power is obtained from a DC
power converter that attaches to the vehicle’s electrical system

Installation Guide

via an access cord. Installation of the VRC 4040 requires

mounting the bracket assembly, installing the DC power

converter , and attaching the ac cess cord to the vehicle’s electrical

system.

Caution

For proper operation on electric fork lifts, the VRC must be
isolated from the chassis. Damage to terminal could result.

The three types of mounting bracket assemblies are:

• univers al mounting ass embly

• hyster mounting assembly

• crown mounting assembly.

Installation Guide

Providing Power to the VRC 4000

Power is provided to the VRC 4000 terminal via a locking DC­power adapter, as illustrated below:

All cable connections should be made to the VRC 4000 before
the system is powered up. Since ther e is no ON/OFF sw itch, the
VRC 4000 powers up as soon as the power supply connections
are completed and the power supply is plugged in to the 110
VAC electrical outlet.

Providing Power to the VRC 4040

Power is provided to the VRC 4040 via a DC power converter (12
V or 24-48V) that is connected to the vehicle’s battery. The DC
power converter mounts to a steel surface on the vehicle via
magnetic feet. Locate the converter so as not to interfere with
either moving parts on the vehicle or the operator’s vision. Be
certain that the power cable from the DC power converter can
reach the mating co nnector on the VRC 4 040.

The access cable should be connected to the vehicle’s electrical
system, at the point that provides power at all times and that is

11

12

filtered and fu sed. Never c onnect the access cable dir ectly t o the
battery terminals. Possible connection points are at the horn,
lights (feed), or ignition switch (feed).

24-48 V Power Converter

The electrical harness access cable for the 24-48 V Power
converter has two leads at one end which are permanently
wired into the vehicle’s electrical system. The other end of the
cable has a circular 2-pin connector with rubber boot that mates
with a similar connector on the DC power converter’s power
input cable.

Caution

On some older electric fork lifts, it might be necessary to in­stall a 4 amp, 25 mhy f ilter choke (STANCOR p/n C-2686
or equivalent) in series with the positive lead to prevent
motor transients from interfering with the terminal.

The black harness wir e is con nected to a positive voltage source .
The white harness wire is connected to the negative voltage
source. The booted connector end of the cable should be
accessible for conveni ent atta chment to th e DC power conv erter.

Make sure that the DC power converter ON/OFF switch is in
the OFF position. Once the access cable is wir ed to the electr ical
system, mate the connectors on the access cable and the DC
power converter power input cable. All cable connections must
be completed before applying power to the VRC 4040.

12 V Power Converter

The electrical harness access cable fo r t he 12 V pow er conve rter
has three leads at one en d which are perma nently wir ed into the
vehicle’s electrical system. The leads ar e white and black, plus a
third lead that is either shield braid or green. The other end of
the cable has a circular 3-pin connector with rubber boot that

Installation Guide

mates with a sim il ar connector on the DC power converter’s
power input cable.

The black harness wire is c onnected to a positive volta ge source.
The white harness wire is connected to a negative voltage
source. The green or braided lead is connected to chassis
ground. The booted connector end of the cable should be
accessible for conveni ent attac hment to th e DC power co nverter.

Make sure the DC power converter ON/OFF switch is in the
OFF position. Once the access cable is wired to the electrical
system, mate the connectors on the access cable and the DC
power converter power input cable. All cable connections must
be completed before applying power to the VRC 4040.

Maintenance

The VRC is designed to operate normally in industrial
environments which may contain high levels of airborne
contaminants inclu ding dirt and s moke. Periodic cle aning of the
VRC is recommended to r emove bu ild-up of for eign sub stances
on the case and touchscreen.

Before cleaning, remove power from the VRC. Wipe
accumulated dirt and dust from the case with a slightly
dampened cloth, paying particular attention t o the ang led edge
of the bezel. Clean the touchscreen with a commercial brand of
computer screen cleaner and a soft, damp cloth or compressed
air.

Radio Frequency Interference Requirements

This device has been tested and found to comply with the limits for a Class A
digital device pursuant to Part 15 of the Federal Communications Commissions
Rules and Regulation. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interfer ence in which case
the user will be required to correct the interference at his own expense.

However, there is no guarantee that interference will not occur in a particular
installation. If the equipment does cause harmful interfer ence to radio or televis ion
reception, which can be determined by turning the e quipment of f and on, the user
is encouraged to try to correct the interference by one or more of the following
measures:

• Re-orient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the e quipment into an outlet on a circuit different from that which

the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.
