Online Unit, the LNB Bias Tee setting is driven by that unit’s Tx Mute
setting (MUT) – If MUT=0, then SBT=1; if MUT=1, then SBT=0.
•
LCS=0 (the LNB Current Source is DISABLED – no voltage transmitted), or,
if so equipped, 1-4 (where the selected LNB Current Source is 1=18V 22
kHz Disabled; 2=18V 22 kHz Enabled; 3=13V 22 kHz Disabled; or 4=13V 22
kHz Enabled).
For the Offline Unit tabulation:
The Offline Unit monitors the Online Unit
control settings and updates its settings every few seconds. As tabulated,
“FOLLOW” means that this Offline Mute control setting “follows” the Online

A.2.3 Troubleshooting Connectivity Issues
Each network is unique, and network configuration and management
are outside the scope of this manual. This information is provided as a
helpful troubleshooting tool, but trained network specialists may be
required to make an Ethernet-enabled product work in a specific
network. This section offers common solutions to network
