PCIe Slot (1)
The PCIe Slot is a standard 3/4 length auxiliary PCIe slot that supports optional PCIe
devices. The PCIe Slot is configured to allow PCIe card I/O Connectors to be accessible
from the 301x's front panel.
Audio I/O Connectors (2)
Audio Input
The Audio Input Connector is a 3.5 mm input jack that provides for single-ended L/R stereo
input with a 100 kOhm resistor to ground. Audio Input circuitry provides ESD protection
and a unity gain stage buffer to the stereo L/R signals.
Audio Output
The Audio Output Connector is a 3.5 mm output jack that provides single-ended L/R stereo
output. Audio Output circuitry provides DC coupled stereo output and gain stage buffering
that compensates for signal loss during filtering.
Gb Ethernet Connector (3)
The RJ45 Gigabit Ethernet (GbE) Connector provides 10/100/10000 Base-T
Ethernet connectivity between the COM Express Module and the shelf base fabric. The
GbE Connectors should be used to connect peripheral equipment to the 301x Module; the
Chassis's Ethernet connector should be used to establish a wired network connection.
