5.1.3 Video Playback

During the configuration and installation process, it may be necessary to verify the COM46

video streams in the absence of a Pro:Idiom enabled television.

The COM46 card can facilitate this type of debug activity by allowing the user to bypass the

Pro:Idiom encryption process temporarily. It should be noted that this feature is only available

when tuning to DIRECTV channel 100. Please refer to Section 1.1 (“Security_Mode” setting)

for additional information on this feature.

If you wish to take advantage of this feature, you will need a video player on the PC that is

capable of decoding MPEG video transferred via IP Packets. VLC Media Player, which is a free

download, can decode MPEG video and can be found at the following URL:

5.1.4 System Logging

The COM46 cards have the ability to send logging data to a remote destination. This is

especially useful in situations where a management PC will remain with the COM2000 systems

at all times, but it can also prove helpful when setting up and troubleshooting a system.

One simple solution is the syslog feature of the previously referenced Tftpd32, but it is limited in

terms of features. A more feature-rich option might be considered for a more robust debugging

capability. One alternative solution is an offering from Kiwi Enterprises (available at

http://www.kiwisyslog.com/), but this option carries a licensing fee for a full version of the

software, so it may not be a viable option for the casual user.

Each COM46 card provides a limited syslog capability. The cards are only capable of displaying

500 lines worth of log-data, so this may not be an appropriate tool for long-term system

troubleshooting. However, the syslog feature can be quite useful if the system operator is able to

access it within that window of time after a card begins to exhibit some unexpected behavior.

Each COM46 also includes a SOAP event monitor and an automatic, periodically generated,

SOAP status message that can be configured to be transmitted from the card. Both types of

messages can be configured to be sent to either a local or web server with appropriate firewall

settings of the network. See Section 6.2.7 for more details on configuring these messages.

5.1.5 TFTP/FTP Server

The COM46 cards have the ability to transfer data to and from an external source via either an

FTP (File Transfer Protocol) or a TFTP (Trivial File Transfer Protocol) server. The data

transferred will typically take the form of software upgrades, but it is also possible to configure

the system to log system status messages remotely for troubleshooting.
