Main OSD Menu Setup Menu
OSD Main menu
To select computer: use Up/Down Arrow key to navigate, PgUp/PgDn
to scroll page. Enter to select computer.
F1: Toggle between the OSD Main Page/ Setup Page/Status Page
F2: Logout: lock your keyboard and mouse for security. You have to
enter user name and password to gain access to the local console again.
The local console password authentication can be enabled/disabled
via Prima IP Web management interface. Just go to Prima IP Web/Local
Console Page/Local user needs Authentication – to enable/disable it. If
it is enabled, you will need to enter a user name and password for local
console access. Further, the local console user cannot perform port
switching on local console (that is, port switching is only possible with
remote viewer).
The local console only accepts user name and password with
UPPER CASE. Thus, to configure a password account that is usable not
only for the remote viewer connection but also for the local console
access, you should add a user name/password that is all in UPPER
CASE (that is all with CAPITAL LETTERS).
OSD Setup Menu
Autologout: specify a time for auto logout (00~99 min)
Title bar: specify the position of the OSD title bar
Hotkey: specify the hotkey preceding sequence
(SCROLL LOCK, CAPS,
F12 or NUM LOCK)
IP: specify the IP address of the Prima IP KVM switch.
Submask: specify the subnet mask for the Prima IP KVM switch.
F 10: Save the configuration.
Esc: Quit
To change computer name, you have to access Prima IP Web
management interface/Computer names. The OSD Menu does not
provide this computer naming function. Please refer to previous section,

Prima IP Basic Configuration Diagrams
Basic Configuration 1 – Prima IP 8 connected with 8 servers
Basic Configuration 2 – Prima IP 8 connected with serial power
control device such as ioPower
Basic Configuration 3 – Prima IP 8 as a PPP server to receive
dial-in call from a PPP client
Basic Configuration 4 – Prima IP 8 as a PPP client to dial out to
a PPP server
Basic Configuration 5 – Prima IP 8 is cascaded with Prima KVM
switches to upscale port capacity up to hundred to computers.
Firmware/Software Upgrade
This KVM Switch allows its user to upgrade firmware/software
whenever is needed to enhance the compatibility to other devices or its
function and performance. Use the Prima IP Web to upload the
firmware/software upgrade files. To upgrade either the firmware or the
software, you should have your upgrade files ready on your client
computer, then go to the Maintenance page of your Prima IP Web
Mamgement, and upload the files therewith ….
Troubleshooting
Q. I can see the screen output on local console. It’s OK. However, there’s only
No Video on the viewer screen when connected. What’s up?
A. You might have adopted a resolution or refresh rate too peculiar for Prima IP,
please try to change the frequency to more standard ones such as 70/ 72/ /75 Hz.
And also if that does not help, try to change the pixel dimension as well to say
800 x 600 / 1024 x 768 / 1280 x 1024 / 1600 x 1200.
Q. The Prima IP booting time has become unduly longer over several minutes.
What’s wrong?
A. Please make sure that the external authentication, PPP server/client, time
server as well as power control settings are correct. If you don’t use all these
features or the authentication/time servers are not available, just try to disable
them to save booting time. If you don’t have all these servers present, the Prima
IP settings will force it to try to look for them till timeout. That will waste Prima
IP booting time considerably.
Q: Video response seems slower in limited bandwidth condition, are there ways
to increase the response speed?
A: There are several ways to increase the response speed on the viewer screen:
(1) Under bandwidth limited condition, you should select a more economical
encoding scheme such as Internet Encoding scheme instead of the LAN or
RAW encoding scheme from the viewer connection option menu. However,
if the connection is made only within LAN with plenty connection
bandwidth, LAN or RAW encoding scheme should be (paradoxically)
quicker than Internet scheme – since your client computer won’t dissipate
extra computing power for decoding the more-compressed internet scheme.
(2) Use 8-bit color reduction (with only 256 colors instead of the 65K colors in
16-bit settings).
(3) Use JPEG compression (for best video quality with optimized packet
quantities).
(4) Additionally, you could always select either Medium Quality/Low Quality
level for more speed as your Video Filter setting in the Video Server Page
of the Web Management Interface. You could also do something to increase
the response speed: use a server desktop of small resolution (such as 800 x
600) and use a solid plain color background for server desktop.
Finally, you should check also the networking environment to find if there is
some bottleneck that can be improved or eliminated for more bandwidth
throughput.
Q. When connection is first made, the display on the viewer screen seems not
centered correctly and there is black margin on the edge of the viewer screen.
How could I eliminate the black strip?
A. The black strip is the offset that will be seen when the display on viewer
screen is not centered correctly. Probably you have not enabled automatic
centering option on Prima IP, so please check the followings:
(1) Go to the Video Server page on Prima IP Web Management Interface to
check whether the Automatic Screen Alignment option is enabled. If it is not
yet enabled, please check the option, click Submit button and then go to
Apply Settings
page to click the Apply Settings button to restart Prima IP
with new setting.
(2) When the viewer connection is made, select the Adjust Screen option on
Viewer’s Quick Menu, and the Adjust Screen dialog box appears. On it,
check whether you have Automatic Centering enabled. If it is not yet
enabled, please check this option to enable it. If it is already checked, please
uncheck it and then wait for at least 15 seconds and then check the option
again to force the video server to align (center) the display in the viewer
screen.
Q: I can log in and make successful browser connection with Prima IP. However,
I cannot make a valid viewer connection or the Prima IP does not respond to my
viewer connection request. What can I do about it?
A: The Prima IP video server might not function properly. First, make sure your
account have the SUPERADMIN privilege. If not, you should request one that
has the SUPERADMIN privilege to do the troubleshooting job for you. Next, go
to the Apply Settings Page on the Web Management Interface and then hit the
Apply Settings
button to restart Prima IP. Then wait for at least 10 more seconds
for it to start completely. Try to make the viewer connection again to see if it is
back to normal. Second, If the Apply settings button could not bring back the
Prima IP video server to normal working condition, try to hit the Emergency
Reboot
button (could be found on the Maintenance Page of the Web Management
Interface) for a complete start from ground level. An Emergency Reboot is a
clean reboot, and it takes longer time for Prima IP system and video server to load,
thus you have to wait at least a minute for the system to be up and running. Then
try to make the viewer connection again to see if it is brought back to normal
function again. A cold boot of Prima IP is always a last resort to bring the Prima
IP back – just try to disconnect the power adapter form Prima IP and wait for
sometime (30 seconds) before plugging in again for a cold start over.
