Starting
The program searches for a camera, soundcard, the local IP and
updates. You have to submit a username, for example your
email. ‘Continue’ and check any firewall messages to open
REMSEM for connection
‘Send Email’ opens your email program. Send the edited
username/email to a contact person so that he or she can use
this to connect to your computer.
Use ‘Check Settings’ to test the microphone and speakers.

If you have no camera
• When using REMSEM without camera, one
can select a JPG-image instead, reloaded
regularly during session and at start-up.
• When a camera becomes available, it can later
be enabled from the settings panel.
• If a camera is installed but used by another
application, REMSEM can use a JPG-image
instead.

DSL Modem
If connecting through a
DSL modem, the IP
behind the modem
appears different to that
seen from outside. The
program tests for this
and shows the
information on the left
provided it can get
through the internet.
For incoming connections one needs to enable ‘port forwarding’
because the remote PC needs to be able to connect the computer
directly. Enabling this should be explained in the manual for the
modem.

Status-bar during connection
If in presentation mode, visible
screen, cursor and speaker icons indicate full connection.
An automatic redial occurs when one or all of the three
connections get interrupted.
REMSEM automatically updates the IP number to catch if the
remote side opened the program after dialing and/or on a
different computer.

Drag-and-drop files
from local desktop
anywhere here and
they appear on the
remote desktop

Speeding it up
To speed up the feed-back screen on the client side, try the following:
1. Right-lick on the server-desktop to open the properties menu (only applies to the
computer you want to connect to; best do this before remotely connecting to this
computer)
2. Click on ‘Properties’
3. Select ‘Settings’ optionally select smaller screen size and smaller color resolution
4. Further, click on ‘Advanced’
5. Click on ‘Troubleshoot’
6. Slide ‘Hardware acceleration’ to the lowest value (also needed to see movies).
7. Press ‘OK’ (this resets the screen)
In addition, select from the settings menu in REMSEM:
4-bit gray, which runs with smallest amount of data to be sent.
8-bit color-scale, as the fastest mode, but picture quality is reduced.
15-bit color mode, to produce a brilliant picture, but which is rather slow.

Preparing Your Talk
• Preparing a presentation includes uploading
your
presentation files to the seminar side after
insuring
‚transportability‘; test it out by moving your talk onto
another computer and check that PowerPoint finds all
related files
• Save the presentation as web page when it contains
several *.wrl or a Java applets *.Class, and edit the
references to these files by hand. Then compress all files
in a *.zip to be send to the seminar side
• Send the seminar side the website-link to the REMSEM
program so that they can download the software
• Retrieve the username and password to connect to the
seminar side with which they opened their program
(c) Werner Kaminsky
On the seminar side ...
• He/she connects camera, microphone,
speakers, the LCD projector and opens the
program
• He/she sends her/his username and/or
password to the speaker
• He/she prompts firewalls
• There is no further knowledge required to set
up the connection other than knowing how to
connect the devices to the computer and start
the program.
(c) Werner Kaminsky
Connection safety
The program allows for 2 different modes of
connection defined in ‘Settings’
• Password check:
password edited and checked, no prompt,
best for Remote PC applications
• Check incoming calls:
prompt incoming calls (it rings when ‘Sound
Effects’ is checked): when a call comes in,
someone needs to be at the computer to
prompt it.
Client can see the remote PC
(not recommended for Remote PC
applications, password does not matter )

General tips for the speaker
• Check for any time-difference between speaker time zone
and the seminar time zone.
• Ask your representative on the seminar where he/she
installed all files on the computer used for the presentation.
If the seminar side uses a DSL modem make sure they
enabled port forwarding for ports 10010 (UDP) and 10011
through 10015 (TCP).
• Test the connection with your seminar representative under
real conditions!!!
• Press on the presentation button
to clean-up the
screen. Press it again to recover
all buttons.
• Enable ‘automute’ from the settings panel if it is too
irritating hearing your own voice’s feedback
• Put your camera on the left of the monitor and enable
horizontal mirroring. This makes you look towards a
presentation or at the audience when you turn your head.

Shutting down
There are three modes of ending
REMSEM:
1.
Close all:
Close Remsem and
remove standby and restart registry
entries
2.
Disconnect: Stop a connection and
leave REMSEM running
3.
Standby:
Close camera,
minimize REMSEM, edit registry for
auto-login and restart. This requires
to type-in the windows login
password (and username).

In case of trouble ...
o Consider this:
o Firewall messages need to be prompted
o REMSEM uses the ports 10010 through 10015. If on a DSL
modem port forwarding needs to be enabled to receive a talk
o Be patient, the program sorts out most problems
automatically!!!
o if you lost control or - audio then try the refresh
button, alternatively, close the program and try to
reconnect. If on the seminar side, try ‚Control+Alt+Delete‘;
this may unlock the mouse. Close whatever popped up and
leave the screen to the speaker. Try to restart the program or
the whole computer if nothing else helps
o If you have trouble connecting check the email you typed in
and the password: to do so click ‚Cancel‘ then ‚Make a call‘
