Noise reduction circuitry, surge protection, reverse polarity protection, 
and power conditioning circuitry are built into the HAMMERDOCK.  In 
some cases a GPS receiver may also be included.  Connectivity on the 
rear of the HAMMERDOCK includes a power connector, keyboard 
connector, and USB connector.  Connectors in the “break out box” at the 
end of a 3’ or 6’ cable include 1 keyboard, 2 COM ports, 1 USB and 1 
parallel port. 
 
No adjustments are ever required to assure precision insertions of the 
docking connector.  The tension of the tilt/swivel functions and the angle 
of the keyboard tray are the only adjustments available on the 
HAMMERDOCK.  All tension adjustments are made at the time of 
installation with an Allen key provided with each docking system. The 
keyboard tray is removable. 
 
The computer can be secured in position by turning down the spring-
loaded red retention latch.  Once the latch is turned completely down, 
the push button lock can be depressed to prevent unauthorized removal.  
Security keys for fleet users are identical to eliminate logistic problems. 
 
The HAMMERDOCK cannot be installed without a base to mount it in the 
vehicle.  Contact WalkAbout for a current list of vehicle mount providers. 

 

Heater option 

 

The HAMMERHEAD XRT supports an optional heater package that 
greatly improves display readability in colder environments and a hard 
drive heater that prevents drive freezing. You can enable the heaters to 
automatically activate while your machine is running, booting or even 
while it is turned off.  If enabled, the heaters will automatically activate 
each time the ambient temperature falls below a predetermined level.

Cardbus/PCMCIA cards 

 

Cardbus and PC Cards are two alternative types of PCMCIA interfaces 
(or slots) on laptops, desktops, and PDAs. PCMCIA cards are based on 
a 16-bit interface, while CardBus is a 32-bit interface. This allows the 
CardBus Card to transfer data at speeds exceeding 100 Mbps, while a 
16-bit PCMCIA card transfers data at approximately 20 Mbps. CardBus 
also offers lower power consumption: CardBus Cards are all 3.3-volt 
cards, while 16-bit PCMCIA Cards can be 5-volt or 3.3-volt. 
 
The Type III slot in the Hammerhead XRT will support both Cardbus 
and/or PCMCIA cards. To insert a card, take off the hatch plate by 
removing the two screws that hold the hatch cover. Cards should be 
inserted face up (i.e. the up arrow on the card should point toward the 
front of the HAMMERHEAD XRT).

 Do not apply excessive pressure 

when loading cards. 

 They should slide in easily.  Remove the card in 

the same manner.   

 

Many PCMCIA devices require connections for communications (RJ-11 
or RJ-45) or antenna for wireless activity (wireless modems, GPS) or 
some other external function.  Most PCMCIA devices are too fragile for 
direct connections in field environments.  In response, WalkAbout 
provides a variety of hatch plates with a milled cavity or “lump” containing 
combinations of connectors and the cable assemblies needed to connect 
to common PCMCIA devices.  For example, a “lump” to accommodate a 
PCMCIA fax/modem and network connection includes a RJ-11 and RJ-
45 connector.  A “lump” for a CDPD modem and wire-line fax/modem 
would include an antenna mount and RJ-11.  The “lumps” serve two 
purposes:  1) they provide for a sturdy and highly reliable connection not 
possible when connecting directly to a PCMCIA device, and 2) they 
maintain the environmental integrity of the HAMMERHEAD XRT by fully 
sealing the PCMCIA compartment while providing the needed 
connectivity.  “Lumps” are available only for those PCMCIA devices that 
have been tested and recommended by WalkAbout.  Custom “lumps” 
may be available for large purchases. 
 

Internal “Flex Space” for OEM modules 

 

In addition to a Type III Cardbus/PCMCIA slot, the computer has an internal “Flex 
Space” that will accommodate optional GPS, GSM and Bluetooth modules.  The 
antenna for the internal module is mounted on the top right hand side of the 
computer and does not interfere with the Cardbus/PCMCIA door and antenna 
options, which is located on the upper left hand side of the computer.
