Ethernet network through a  single bay USB cradle.
Figure 4-6USB-Ethernet Adaptor Cable
• Insert the adaptor’s USB connec tor into the Host USB port on the single bay USB cradle.
• Connect your network Ethernet c able to the Ethernet port on the adaptor cable.
Network Access
The hand-held unit automatically  detects insertion into the cradle and loads the appropriate drivers to commu-
nicate with the USB-Ethernet converters.
Network Addressing
The host application uses standar d TCP/IP protocol to name, locate and communicate with a specific Worka-
bout Pro4 on the network. If a link is established between a Wo rkabout Pro4 and a host, the application on the 
host and on the hand-held must have a recovery mechanism in the  event that the Workabout Pro4 is removed 
from the cradle, int errupting the link.
Troubleshooting the Single  Bay USB Cradle Operations
The indicators, applications and drivers required to use and mo nitor the single bay USB cradle as a dock (as 
opposed to a charger) are installed on the Workabout Pro4 – no  applications are present on the cradle itself.

The four bay Ethernet Cradle permits each of four docked Workabout Pro4s to communi cate with a 10/100 
BaseT Ethernet network at greate r than 2Mbps. It also provides sufficient power to operate and fast charge the 
batteries in the units.
Four Bay Ethernet Cradle Setup
After unpacking the unit:
• Visually inspect the  unit for any damage. 
• Install the IEC power  cord and apply power. 
A green indicator in the lower-right corner of the front panel  lights up to indicate that power is present. 
• Attach a CAT5 RJ45 network patc h cable (supplied) between your network and the RJ45 jack on the rear 
of the cradle. 
A green LED is illuminated next to the RJ45 connector when a va lid network link is established.
A user application must be loaded onto each Workabout Pro4 that  utilizes the cradle for communication. When 
the network is connected and th is application is loaded, the cradle is ready for use.
Four Bay Ethernet Cradle Indicators
The four bay Ethernet cradle is e quipped with a power indicator LED and RJ45 link and traffic indicator LEDs. 
When a valid network  link is established, a green LED is illumi nated next to the RJ45 connector.
Inserting a Workabout Pro4 in  the Four Bay Ethernet Cradle
• Slide the unit into the cradle p ortion of the four bay Ethernet cradle until lightly latched.
The hand-held detects that it is in a four bay Ethernet cradle  and momentarily displays the appropriate icon in 
the navigation bar at the top o f the screen –  . The LED on the  hand-held unit lights up to show it has 
external power and may start charging the battery.
Interaction with the Workabout Pr o4 while in the four bay Ethernet cradle is a function  of the user application 
software used to communica te with the host network.
Network Access
The four bay ethernet Cradle has  one 10/100 Ethernet port. You can insert up to four hand-held units. The 
hand-helds are connected to an  internal USB hub. The hand-held  unit automatically detects insertion into a 
four bay Ethernet crad le and loads the appropriate drivers to communicate with the U SB/Ethernet converters.
Network Addressing
Although the USB converters have fixed Ethernet MAC addresses,  there is generally no correlation between 
these addresses and a specific hand-held. The host application  uses standard TCP/IP protocol to name, locate 
and communicate with a specific W orkabout Pro4 on the network. 
If a link is established between a Workabout Pro4 and a host, t he application on the host and on the hand-held 
must have a recovery mechanism in  the event that the Workabout Pro4 is removed from the cradle and the link 
is interrupted.
Battery Charging – LED Behaviour
The four bay Ethernet cradle supplies DC power to enable the Wo rkabout Pro4 internal fast charger. Charge 
status is displayed on the hand- held LED – the LED turns red while the battery is bei ng charged and turns 
green once the charge is complete. If the battery is fully char ged when the unit is inserted in the cradle, the  
						

							4 - 16 Workabout Pro4 (Windows Embedded CE 6.0) User Manual
LED flashes red for less than a second and then turns green. Ba ttery charging continues whether the Worka-
bout Pro4 is switched on or off.
It can take up to  4 hours to fully charge the internal battery.
Troubleshooting
The indicators, applications and drivers required to use and mo nitor the cradle are installed on the Workabout 
Pro4 – no indicators or applicatio ns are present on the cradle itself.
Network Link Unsuccessful
If a network link fails, the Worka bout Pro4 application alerts the operator that the link was unsuccessful.
Hand-Held LED does not Light when Docked
• Check that the four bay Etherne t cradle has power – is the Power LED on the cradle illuminated?
• Try inserting the Workabout Pro4 in another well in the cradle .
• Check for dirt or contamination on the docking contacts at the bottom of the Workabout Pro4. Wipe the  contacts with a damp cloth if necessary. 
• Check the pogo pins inside the  cradle for dirt. Gently wipe with a damp cloth if they appear to be dirty 
or discoloured.
• Check that the pogo pins are not bent or damaged.
• Remove and reinsert the Workabout Pro4 in the cradle, and chec k that the latch is holding the unit in place 
(the pogo pins must be compr essed for proper contact).
• Make certain that the battery i nstalled in the Workabout Pro4 is not defective.
Four Slot Battery Charger
The four slot battery charger is designed to charge up to four Lithium Ion batteries at one time.
Charging the Battery
• Slide the battery into a charge well, aligning the contacts on  the battery with the contacts in the 
charge well.
Battery Charge Duration
A fully discharged battery can take up to 4 hours to charge. Th e four slot battery charger stops applying power 
to the battery when it is fully c harged – there is no risk of overcharge if the battery r emains in the charge well. 
The 75% charge indicator is handy  if you need a quick recharge – a quick charge often takes less than 
one hour. 
						

							Peripheral Devices & Accessories 4 - 17
Charge Indicators – The LEDs
Each battery charge we ll is equipped with an LED to indicate th e charge status of the b attery. When a battery 
is inserted in the charger, the colour and behaviour of the LED  associated with the charge well in use indicates 
the status of the charge. Refer to the table below the heading  Charger LED Indicators on page 4-12 for details.
Troubleshooting
Excessive Charge Duration
The charger is equipped with a recalibration function – a funct ion that fully discharges and then fully recharges 
the battery. This process is nec essary to recalibrate the battery capacity gauge interna l to the battery. The 
charger attempts recalibration when: 
• the battery capacity is at less than 30%,  and
• the battery has undergone more t han 40 partial charge cycles since the last full discharge.
Indicator Flashing Red
If the indicator flashes red:
• Remove all batteries and dis connect the mains power cable.
• Wait at least 20 seconds, and th en plug the cable in again.
If any of the charge well LEDs c ontinue to flash red, the charger is defective an d requires service. If all indica-
tors are flashing red,  there is a power supply problem and the  charger requires service.
Power LED Does Not Light Up
• Remove all batteries,  and unplug the charger.
• Connect another device  to the mains outlet to ensure there is  power.
• Remove the IEC mains power cabl e from the charger, and check it for damage. 
• Reconnect the mains cable in  the charger and mains outlet.
If the powe r LED still does not light up:
• Unplug the mains cable, and che ck the fuse at the rear of the charger.
If the fuse appears to be intact, the charger requires service.
Indicator Does Not Light When Battery Installed
• Remove the battery, a nd clean the contacts on the battery and  the charge well.
• Reinstall the battery, and che ck that it is fully seated in the charger well.
• Inspect the charge well contacts for damage (are they bent, fl attened, twisted or broken).
• Try inserting a battery that y ou know to be working in the charger well.
• Reconnect the mains power cab le, and check that the charger well indicator flashes at power up.
The Vehicle Cradle
The vehicle cradle is a highly ruggedized, single station dock.  Although it provides quick insertion and removal, 
the cradle holds the Workabout Pr o4 securely even when operated in high vibration environments.
The model number for vehicle cr adles varies depending on the ty pe of hand-held:

A port replicator option is available for powered vehicle cradl es. Refer to The Port Replicator on page 4-20  
for details.
Vehicle Cradle Mounting Recommendations
Before mounting a vehicle cradle in a vehicle, there are a numb er of operator safety issues that require careful 
attention. An improperly mounted cradle may result in one or mo re of the following: operator injury, operator 
visibility obstruction, operator distractio n and/or poor ease of egress for the operator . Zebra strongly recom-
mends that you seek professional  mounting advice from the vehicle manufacturer. 
Cable routing within a vehicle cab also requires careful consid eration, especially for separately tethered scan-
ners and other devices with loose cables.
Note also that fo r better protection, the equipment should be m ounted inside the vehicle roll cage.
Pedestal mounts are recommended for all fixed mount locations b ecause they offer optimal operator access. In 
addition, for safety reasons,  only pedestal mounts with fully l ocking joints should be used in vehicles. Always 
adjust the pedestal for the opti mum viewing angle, and securely  tighten the hex and wing screws.
The most effective way to mount  the vehicle cradle is to use the four #8-32 threaded inserts on the rear of the 
unit. Bolts must not extend more  than 10mm (3/8") into the cradle.
To accommodate the service loop of  the connector cable, leave a 4" clearance at the bottom of the cradle. 
Leave a 7" (minimum) clearance  at the top of the cradle to allow easy removal of the hand-held. 
Also remember to leave at least a  3" clearance at the sides of the cradle to allow activation of the release 
knobs. Refer to the detailed asse mbly instructions that are packaged with the cradle when selecting a 
mounting location.
Mounting Template
The vehicle cradle is shipped wit h detailed mounting instructions including a drill template.
Wiring Guidelines
Before installing cables between  the cradle and other devices, review the following:
• Ensure that drilling  holes will not damage the vehicle or its wiring.
• Protect cable runs fr om pinching, overheating and physical dam age.
• Use grommets to protect cabl es that pass through metal.
• Use plastic straps and tie-dow ns to secure cables and connectors in their desired location, away from 
areas where they may get snagged or pulled.
• Keep cables away from heat sour ces, grease, battery acid and other potential hazards.
• Keep cables away from control pedals and other moving parts th at may damage the cables or interfere 
with the operati on of the vehicle.
IMPORTANT Shock and vibration specificatio ns for the Workabout Pro4 are v erified using 
Zebra-approved RAM mounts and mou nting hardware. Use of non-certified Zebra 
mounting hardware is not recomm ended, and may void warranty coverage.
