|
| Content Manager Server |
| Q1: |
Can I preview
the playlist before actually scheduling the files
to be played? |
| A1: |
Yes, you can assign the playlist
to be "Previewed" on any WebDT signage
device using the Web Content Manager. |
| Q2: |
How do I broadcast
an emergency message immediately to all deployed
signage displays?What happens if Internet connection
is interrupted or lost? |
| A2: |
The WebDT Content Manager incorporates
a feature called the "Urgent Cast", whereby
the manager of the system can send an urgent ticker
message (font sizes, colors can be changed as well)
to all deployed displays. The ticker can interrupt
a scheduled message, or lay over the content being
played. |
| Q3: |
How many zones
are supported in the current version of WebDT Content
Manager? Can I define my own zones? |
| A3: |
8 zones are supported under the current
version. Yes, users can predefine the size, placement,
and files for zones. 10 predefined system templates
are also provided. |
| Q4: |
What about RSS
feed? Do I have access to real time RSS feed from
the Internet? |
| A4: |
Internet RSS sites can be incorporated
into the playlist such that the system will automatically
retrieve up to date RSS feeds. |
| Q5: |
How do you get
a URL zone to force a refresh (not just show the
cache) when you can’t control the web site? I have
a zone that is alternating two URLs, but it is just
showing cached data, not refreshing when the switch
happens. |
| A5: |
Option #1 |
| |
The easiest way may be changing IE
setting (On the player) from
Tool | Internet Options | General | Browser History
Setting, pick “Every time I visit the page”. This
should prevent IE from fetching information from
cache. |
| |
Option #2 |
| |
Server set expiration and no-cache
is the most common way so server (content creator)
can control it. This option is good if you have
control over the web server where the URL resides. |
| |
Option #3 |
| |
Client side html/js to enforce no
cache is also ok, but a little tricky. This has
to be programmed by the javascript programmer (or
other programming languages). This option is good
if you have control over the web server where the
URL resides. |
| Q6: |
What are the
server and communication port numbers required for
the WebDT Content Manager? |
| A6: |
DT Research WebDT Content Manager
(WCM) System Requirements |
| |
Hardware: |
| |
| 1. |
1 GB DRAM or above |
| 2. |
Pentium 4 CPU 2.0 GHz or above |
| 3. |
10/100Mbit Ethernet Adapter |
| 4. |
Hard drive Space at least 80GB |
|
| |
Software:
|
| |
| 1. |
WebDT Content Manager runs on Windows Server
2003 R1/R2 Standard/Enterprise Edition. |
| 2. |
Pentium 4 CPU 2.0 GHz or above |
| 3. |
10/100Mbit Ethernet Adapter |
| 4. |
Hard drive Space at least 80GB |
|
 |
|
| |
Communication Ports |
| |
| A. |
User access to WebDT Content Manager
Server |
|
By default, only port 80 (standard
HTTP) is required. However during installation you
can also choose to install the web server on a separate
port number which is not being utilized. Users can
also choose to enable SSL on the web server which
then requires port number 443 to be opened. |
|
|
| B. |
Client Software (SA1000/SA2000
or other WebDT Signage Appliance) to WebDT Content
Manager Server |
|
Again, only port 80 is required depending
on what has been selected as default under section
A. User just needs to go through a onetime “registration”
process in order to punch in the correct server
address and communication is handled by standard
http port. |
|
| Q7: |
When I try to register the WebDT players, it returns the error message “Failed to Register – Cannot connect to the server” message.
The Device Manager is showing a green status on each of the players. Any ideas on why they might not be able to contact the WebDT Content Manager Publishing Server? |
| A7: |
There are many variables that could cause the WebDT Players to not able to connect to the WebDT Server. Please go through each of the scenarios below:
|
| |
| 1. |
Can you login (through IE) to the WebDT WCM server from any of your player? (http://w.x.y.w/) If not, check your Internet/Ethernet connection between the WebDT Player and the WebDT Content Manager Server. |
| 2. |
From the player, can you also launch IE and do a http://w.x.y.w/publish to determine if you can see the following? If you can, that means the WebDT Server is responding to requests. |
|
| |
|
| |
| 3. |
Are the players and servers on the same subnet? Do they have to go through a proxy server? Do you have a firewall in between? Check your proxy server or firewall settings. |
| 4. |
The device manager shows green status but that only checks the health of the system (network connection through UDP is good, the players are still running) and not the application layer (which is handled by the WebDT Content server) |
|
| Q8: |
I recently installed the WebDT Content Manager (WCM) 2.3 I but couldn’t seem to start the WebDT Web Server Service from the Windows Services section? |
| A8: |
WCM 2.3 currently does not support JDK 1.6xx by default, due to the use of Tomcat Server v5.5 which does not work with JDK1.6 if you utilize the default setting. If you have to utilize JDK 1.6, please perform the following procedure additionally on the server: |
| |
| 1. |
Run regedit |
| 2. |
Find the key: [HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Procrun 2.0\WCMWebServer\Parameters\Java\JvmMx], it is the maximum memory used by Tomcat. |
| 3. |
Its default value is: 0x400 (Decimal: 1024MB) |
| 4. |
Change the value from 0x400 to 0x200 (Decimal: 512MB) or 0x258 (Decimal: 600MB) or 0x2bc (Decimal: 700MB) |
| 5. |
Start the web service from the start menu. |
|
| Q9: |
What settings do I need to take care of when uploading a Powerpoint file to be displayed on the WebDT 2.3 player? |
| A9: |
| 1. |
Open the original PPT file and make sure the “show” is setup as “Browsed at a kiosk” and “Loop continuously until “esc” is checked. See screen shot below: |
| |
|
| 2. |
Save it as Powerpoint presentation file |
| 3. |
Login to WebDT Content Manager site and upload the file. |
| 4. |
When you upload the file don’t specify the duration (the system will assign a duration automatically) |
| 5. |
Create your playlist and insert the media file (don’t specify duration here either, let the system assign it automatically) |
