10 Examples of Use
10.1 Intro
This chapter offers a small selection of different practical examples of use of the CP525, with
corresponding recommended configuration steps, pointing to section in
Chapter 8 where the
relevant configuration pages are described.
10.2 Installation in a system
When installing the device in a new environment, there are a few parameters that typically need
to be configured. These steps are the same for all the cases studied below.
1. Set the IP address as described in Section 7.3
2. Assign a name for the device. See Section 8.4.1 .
3. If you are unsure of the state of the device, set it back to factory default configuration
as described in Section 8.4.9.1 .
4. Configure a time zone and a source for the real time clock, to assure alarm log entries
get correct time stamping. See Section 8.4.4 .
5. Enable the input ports to use and disable the ones that will not be used (see Section
8.6.1 ).
6. Enable the output and configure the wanted output bitrate. Refer to Section 8.7.2.1 .
10.3 Raw PID multiplexing
The most basic way of using the CP525 is to work strictly on a PID stream level, multiplexing
streams by manually mapping a number of PIDs through the device.
In this mode you will not depend on the PSI/SI/PSIP signalling on the input signal.
1. For all the inputs in use, disable parsing of all tables, as described in Section 8.6.2.7 .
Doing this, makes all PIDs to be treated as unsignalled PIDs, since the unit will not
know about the PMT on the input.
2. Under Tables on the Outputs tab, configure all PSI/SI/PSIP tables to "Stopped" mode.
3. On the
PIDs
page ( Section 8.7.2.7 ) you can now chose the PIDs that shall be transmitted.
Note: If you leave analysis on PAT,PMT and SDT actual in step 1 above,
you can see the service relations and type decoding of PIDs and, still do
manual PID mappings, but you would have to add the PID mapping with
the flag “Transmit always".
