The Universal Serial Bus is a hot swappable, daisy chainable
serial port with a maximum speed of 12 Mbps. It can be used
for devices like keyboards, mice, floppy drives, CD-ROM or
DVD drives, cameras, modems, scanners, etc. The
HAMMERHEAD 3 supports booting from bootable USB
devices such as floppy drives and CD-ROM drives. Devices
can be connected to the HAMMERHEAD 3 with the computer
turned on, without requiring a reboot. There is a limit of 128
concurrent devices per USB port. The HAMMERHEAD 3 can
supply up to .5 amps of current through the USB port. External
USB hubs are available that will supply power to external
devices without using the HAMMERHEAD 3’s power supply.

PCMCIA Expansion Slot:
The PCMCIA expansion slot is sealed behind a hatch plate
held in place by two Phillips head screws. The hatch plate
must be removed to access the PCMCIA slot. Several hatch
plates are available that will accommodate various PCMCIA
devices with features that extend beyond the housing of the
computer. These hatch plates keep the unit as sealed as
possible and are available for many frequently used PCMCIA
devices. The PCMCIA compartment is sealed from the internal
components of the HAMMERHEAD 3 to prevent dust and
moisture from entering the computer. Cardbus cards are not
supported. Forcing Cardbus cards in the PCMCIA expansion
slot could cause damage.
Speaker:
There is a monaural speaker in the left side of the housing.
The speaker will play windows sounds as well as post error
codes.
AC Power Connector (15 volt input):
This connector allows the user to plug the AC power supply
directly into the HAMMERHEAD 3 to charge and operate the
unit. The unit may also be charged through a port replicator or
docking station.
