X13: USB 2.0 Connection
This connector is used to establish USB (A-B type cable) communication between the host PC and the
Geo Brick Drive. This type of USB cable can be purchased at any local electronics or computer store. It
may be ordered from Delta Tau as well.

Caution
The electrical ground plane of the host PC connected through USB
must be at the same level as the Geo Brick drive. Ground loops may
result in ESD shocks causing the damage of the communication
processor on the Geo Brick Drive.

Note
Use a shielded USB (category 6 or 7) cable. In noise sensitive
environment, install ferrite cores at both Geo Brick and PC side.

If the electrical ground planes of the host PC and the Geo Brick Drive are not at the same level (e.g.
laptop on battery) then the use of an industrial USB hub is highly advised.
X14: RJ45, Ethernet Connection
This connector is used to establish Ethernet communication between the PC and the Geo Brick Drive. A
crossover cable is required if you are going directly to the Geo Brick from the PC Ethernet card.
Otherwise, through a hub, a straight Ethernet cable is acceptable.
Delta Tau strongly recommends the use of RJ45 CAT5e or better shielded cable. Newer network cards
have the Auto-MDIX feature that eliminates the need for crossover cabling by performing an internal
crossover when a straight cable is detected during the auto-negotiation process. For older network cards,
one end of the link must perform media dependent interface (MDI) crossover (MDIX), so that the
transmitter on one end of the data link is connected to the receiver on the other end of the data link (a
crossover/patch cable is typically used). If an RJ45 hub is used, then a regular straight cable must be
implemented. Maximum length for Ethernet cable should not exceed 100m (330ft).
