6 CONFIGURATION AND USAGE
· CHANNEL: 1-158 – sets the output channel num-
ber; the range varies depending upon the channel
plan selected
· PSIP: ORIGINAL, MODIFY, BASIC – the
ACT1000 can modify or insert PSIP tables as
needed. ORIGINAL passes the incoming PSIP ta-
bles unchanged. MODIFY will modify the incom-
ing PSIP tables to user-defined channel numbers,
and BASIC will insert newly-generated PSIP tables
based on user-defined settings; both of these set-
tings must be used in conjunction with the R. L.
Drake Digital Headend Control Program

,
which allows the user to set the new values.
Usage
After mounting the ACT1000 and wiring it to the ap-
propriate 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 sys-
tem 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 dis-
play 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 up-
date process is fault-tolerant; if the unit loses power
during an upgrade, the process can simply be re-
started 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 CD-
ROM that shipped with the Drake PS151 for more
details), click View/Edit on the ACT1000 in ques-
tion, 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).
