Overview
The SyncLink GT2E and GT4E Serial Adapters are add-in cards for use in systems with a PCI Express
expansion slot. The cards provide two (GT2E) or four (GT4E) serial ports for use by the system. A variety
of serial protocols and interface standards are supported. Refer to the software documentation included
with the card for details on using the card for a specific application.

PCI Express
PCI Express is an expansion slot standard for adding components to a system. PCI Express is not
physically compatible with PCI or PCI-X slots. SyncLink cards are physically keyed to prevent insertion
into incompatible slots. The SyncLink GT2E and GT4E are PCI Express x1 single lane cards. This means
SyncLink cards work in any of the different PCI Express slots sizes (x1, x4, x8, or x16). PCI Express x1 slots
are the shortest and x16 slots are the longest.
