LNB Input and LNB Powering
the SCt4860 receives its input signal from the if output of the LNB located on the satellite dish. Because this LNB
output usually is split among multiple transcoders, the LNB power must be obtained from a separate power inserter
and supply that is connected ahead of an L band splitter. the SCt4860 does not have the capability to supply LNB
power.
SETUP AND PROGRAMMING
the programming of each SCt4860 in an Rmt150 rack mounting tray is done from the PS151 power supply
mounted in that rack. the uNit SeLeCt buttons on the PS151 are used to select the unit to be programmed,
including the PS151 itself. the actual programming is done via the five buttons on the left side of the PS151. if the
RS232 remote control is connected, all programming other than the setting of the PS151 RACK iD number and
password programming can be done remotely. the chart below shows each of the menus that are available for
parameter set up and/or viewing for both SCt4860s and the PS151 Power Supply. Pressing the left or right arrow
buttons will navigate through these menus. you may do this without danger of disturbing any of the current settings.
As you navigate through the menus, the parameter is listed on the top line of the display and the current setting
is shown on the bottom line. for set up purposes, it is best to progress clockwise in the chart below (use the right
arrow button), starting from the RS232 adjustment on the PS151 and the moDe menu for each of the SCt4860s.
the charts below show all of the settings that are available through these menus.
