Basic DCS Test
You can verify whether the DCS supports SMPTE captioning by using a lap-
top to connect to the Content Synchronization Port. Disconnect the IRC-28C from
the network. Set your laptop to the IP address of the IRC-28C. Use Tera Term
or telnet to connect to the DCS on port 4170. For example, the command “tel-
net 192.168.1.189 4170” (assuming the DCS IP address is 192.168.1.189) should
connect, dump some garbage that normally includes the model of the DCS. If the
laptop cannot connect to the DCS on port 4170, there may be networking, DCS
configuration, or DCS software issues.
Viewing an RPL
If captions do not run, it is possible that the content does not have captions or
the DCS is unable to decrypt the captions. Click the “Last RPL URL” link on the
IRC-28C main page. You should see the Auxiliary Resource Presentation List
supplied by the DCS. A portion of a typical RPL is shown below.
Note that some servers do not include the IP address in the RPL URL (they
use a relative instead of absolute URL). If the IP address does not appear in the
RPL link on the IRC-28C home page, click the RPL URL link, then type the DCS IP
address in front of the URL in the browser URL field.
