PDM
PDM Operator's Manual Version 2.4a • September 2019
Graphical User Interface and Web Remote Control
You can access PDM from a Web browser in any computer on the data network, if you have
the proper password.
Logging in to PDM from a Connected Computer
n
Launch any standard Web browser, on any Windows, Macintosh, or Linux computer
on your network
1
.
n
Set the browser to
http://nnn.nn.n.nn
, where the n’s are PDM’s IP address. You
can read that address from the
Information
menu on PDM’s front panel.
n
When it connects, you’ll be asked for a
User
Name
and
Password
Use pdmweb as the user name, and pdmweb
Bnnn
as the password. (Bnnn is the
software unique Module Code, which you’ll find on the
Information
screen.
pdmwebBnnn is the factory default password. You can change or view your
password from the front panel in the System / Password menu (
page 31
).
Passwords are case sensitive.
If it doesn’t connect, you may have a problem with your network connections, the version
of Flash installed in your browser, or your system’s configuration
18
.
After successfully connecting, PDM will draw its Graphical User Interface on your
Browser’s screen.
Port Forwarding & GUI Communication
PDM’s web server connects at http port 80. Once you log in and the front panel or configu-
ration pages are loaded, embedded Adobe Flash movies in our GUI let your browser control
the PDM via port 5444. Both these ports must be open and available for the GUI to function.
If you are trying to connect to your PDM over a WAN or across the Internet, you will need
to use a NAT router
19
to route ports 80 and 5444 to your PDM’s local IP address.
If your facility has multiple studios, you may want to control two or more PDMs on the
same network using a single external IP address. You can do this with your NAT router
along with PDM’s built-in port offset feature. The key is to forward pairs of port numbers.
18 This may be a setup issue in PDM’s menus or your local computer, a network wiring or configuration problem,
or even something as simple as entering the IP address wrong in your browser. PDM responds to Ping
commands as an aid for debugging.
19 Network Address Translation Router. Most routers have the ability to forward port requests from specific IP
addresses. Some routers call this feature Virtual Servers. See your router’s instruction manual for details.
