LNB INPUT AND LNB POWERING

The SCT3860 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 SCT3860 does not have the capability to

supply LNB power.

SETUP AND PROGRAMMING

The programming of each SCT3860 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

The chart below shows each of the menus that are available

for parameter set up and/or viewing for both SCT3860s 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 SCT3860s.

The charts below show all of the settings that are available

through these menus.
