Connector Description
POWER ON Button This button is provided for emergencies only, in the event the motherboard in the
receiver needs to be power cycled. Normally, the receiver automatically starts up
without having to touch this power button. Generally, the button needs to be pressed
briefly to turn the unit on, and held for up to 4 seconds to turn the unit off.
(IEEE) 1394 Interface This interface is not used on the SFX3101, but is available for future use.
AUDIO Ports (LI, LO,
MIC, SPDIF)
These are standard unbalanced audio ports: Line Input (LI), Line Output (LO) and
Microphone input (MIC), as provided by the internal AC97 compliant codec. A SPDIF
digital interface is also provided.
PCI Option Slot One PCI option slot is provided for optional PCI cards.
L-BAND This is a 75 ohm, F-type connector that permits connection to the LNB and antenna.
An RG-6 or similar cable of less than 200 feet is recommended. High quality cabling
may be used to provide additional shielding, lower loss or protection from harsh
environments. Direct Current (DC) power is provided to the LNB at either 13 VDC or
18 VDC at 500 mA maximum.
ETHx Ethernet Ports (2) These are bi-directional RJ-45 8-wire (female) connectors, with one 10/100Base-T
auto sensing Ethernet interface and one 10/100/1000Base-T (gigabit Ethernet)
interface. Two status indicators are provided immediately above each RJ-45
connector, as follows:
For the 10/100/1000Base-T interface indicators:
Off/Green/Red (left) – indicates Link speed. Off indicates that the Ethernet interface
is in 10Base-T mode, Green indicates that the Ethernet interface is in 100Base-T
mode, and Red Indicates that the Ethernet interface is in 1000Base-T mode.
Off/Yellow (right) – indicates link status and transmit/receive data activity. Off
indicates that there is no Ethernet link, yellow indicates a valid Ethernet link. Flashing
yellow indicates that there is data activity.
For the 10/100Base-T interface indicators:
Off/Yellow (left) – indicates Link speed. Off indicates that the Ethernet interface is in
10Base-T mode, Yellow indicates that the Ethernet interface is in 100Base-T mode.
Off/Green (right) – indicates link status and transmit data activity. Off indicates that
there is no Ethernet link, green indicates a valid Ethernet link. Flashing green
indicates transmit data activity.
The pinouts for these ports are as follows:
