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 RT 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
The Type III slot in the Hammerhead RT will support both CardBus and/or PCMCIA cards. To insert a card, take off the door by removing the two screws that secure the door. Cards should be inserted face up (i.e. the up arrow on the card should point toward the front of the HAMMERHEAD RT). Do not apply excessive pressure when loading cards. They are keyed and should slide in easily. Remove the card in the same manner.
Most PCMCIA devices are too fragile for direct connections in field environments. In response, WalkAbout provides a variety of doors that extend beyond the housing to contain a combination of connectors and cable assemblies needed to connect to common PCMCIA devices. These extended doors 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 RT by fully sealing the PCMCIA compartment while providing the needed connectivity. Extended doors are available only for those PCMCIA devices that have been tested and recommended by WalkAbout. Custom doors may be available for large purchases.
Internal “Flex Space” for OEM modules
In addition to a Type III CardBus/PCMCIA slot, the Hammerhead RT933 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.
