Usage
after mounting the aCt1000 and wiring it to the
appropriate inputs and outputs, use the PS151 or PC
control program to configure the unit. Remember to
ensure that output levels are matched with all other
sources that will be combined into the final cable system
output. once the unit is configured, the status of the
demodulator can be viewed via the PS151 front panel;
select the unit to monitor, and the display will show the
current state. the top display line will switch between the
unit iD of the aCt1000 and the current input channel,
and the bottom display line will show the current SNR.
if the demodulator is not locked to the input signal, the
bottom display line will show tuNeLoCK to let the user
know that the aCt1000 is trying to tune in and lock to
the input.
the aCt1000 automatically saves all configuration
settings, and will restore them after power is restored after
loss. the firmware within an aCt1000 can be field
updated via the R. L. Drake Digital Headend Control
Program as well, by choosing tools )Download from
the initial screen. this update process is fault-tolerant;
if the unit loses power during an upgrade, the process
can simply be restarted once power is restored.
to set PSiP data, the R. L. Drake Digital Headend
Control Program must be used. once the software has
been configured to communicate with the aCt1000
(refer to the manual on the CDRom that shipped with
the Drake PS151 for more details), click View/edit on
the aCt1000 in question, and then click on the PSiP
Setup button (see figure 1). once the PSiP Setup
window opens, the table information can be extracted
from the existing programs and modified, or new
information can be generated for program streams
that contain no PSiP information (see figure 2).
