Question about Belkin (F1DJ104P-B) 4-port KVM Switch

5 Answers

Cannot switch between PC's

I have 3 PC's connect to this 4-port that I just installed out of the box. I only get one connection(and one light lit up). Which ever PC is connected to port 1 gets control. I cannot use the button on the front, the scroll scroll up or down or number keys, and it will not auto scan. I assume it only sees one PC connected as it only gives me one light lit up (port 1). I can connect any PC up to any port and get power, but the light only shows that it is on on port 1 and I only have mouse, keyboard and vga on port 1. I have tried shutting down all 3 PC's and bringing each one of them up one at a time but get the same result. I had a 2-port belkin kvm connect and that worked fine but since I have dropped a 3rd PC I needed a 4-port. Any help would be greatly appreciated. FYI I have (2) Win server 2003 machines connected and a Win 98 machine. Thanks in advance Matt

Re: cannot switch between PC's

You KVM is bad. I had the exact problem, while using premium Monster cables. Replacing the KVM solved the problem, partially. Now, I have flickering problems at 1920x1200 resolution. It's definitelly a KVM issue also, my friend has the same monitor and video card. With an identical KVM he does not have any flickering. If I install my KVM on his setup, the flickering apears on his setup also.

Re: cannot switch between PC's

Typically, the KVM indicator light will only light up on the connection that is currently active. The indicator light will switch to another connection when that connection becomes active. First I would make sure that all the mouse and keyboard connections are secure. I have seen where these sometimes pop out, and thus some componenty will not work. I would then make sure that all the computers are fully powered on. The KVM will not allow you to switch to a device if it is not powered on. The KVM may indicate that a connection is down by a blinking light if you switch to a port and the connection is not up. It sounds that you have atleast one good set of cables. I would confirm that the other sets of cables are good as well. Do this by swapping the other cables with the one port that you know you have working. Finally, with a set of good working cables, swap them over to the other ports on the KVM switch. Although it may be improbable, you may have a bad KVM. AS always, I would review the product manual here: And, since this is a new product, you will also be entitled to free tech support from Belkin: 1-800-2BELKIN x2263

Also, make sure the PC #1 button is not jammed. I have had a button stick down and it behaves as you describe.

Have lost channels although I subscribe to a basis virgin package, anyone know the codes to bring the missing channels back please, or of a box we can get that will let us receive free channels

They are switching to nagravision 3 area by area. Once your area has switched, you can no longer get all the channels.
At this time no box can get around this , but from what i read, boxes with ethernet connections may be able to work, but no fixes are available yet.

I can't switch to one of my boxes.

1) Make sure your connection to pc3 is good, take out and reconnect both ends.

2) If that has no effect power down the switch for 30 seconds then switch back on.

3) If that has no effect, connect pc3 to the pc2 slot. If PC3 now works, you've got a problem with the switch. If pc3 still doesn's work, its a problem with the pc3 lan connection. You'll need to check "Network connections" in your control panel.

IOgear KVM not working with laptop

First, you have to make sure that the KVM switch is directly connected to your laptop, and NOT to a docking station.

This KVM switch is designed to work with direct connections to the computers.

Second, the light indicator on the KVM switch is not an indicator for power. It's an indicator to see which port is active. If your laptop is connected to port 2, but the focus of the KVM is in port 1, then the port 1 will have a light, not the port 2.

You may also refer to the user manual of the KVM.

Thank you!

Repeated IOGear KVM switch failures

As a wild guess, it sounds like a static discharge MIGHT be affecting the switcher causing it to crash.

Try increasing your humidity to 40% and grounding yourself before touching the keyboard... This is the season for these static electricity problems... get nipped all the time and you MAY not even feel it to be enough to zap the switch.

Cant understand how to get firmware to flash starview 4 box please help

You will need a null modem cable DB9F to DB9F.

Null Modem Cable

If your pc does not have a serial port you will need a USB to serial port adapter to use in conjunction with the null modem cable.

USB Adapter

These two cable links are only for reference as they can be purchased alot cheaper on fleabay.

You will need to know if you have a clone or genuine

Count the vents on top

18x7 = Clone
25x7 = Genuine
13x7 = 1st Generation

Also looking from the front
Scart to the left = Clone
Scart to the right = Genuine

Also you can go here to see some pics


You will need the GTromloader, (Starvi*w software Uploader), found in the Starvi*w software folder of the link.

You will need version CryptStar-v1.5-Core400only firmw@re for GENUINES found in "Starvi*w" firmw@re folder here.

You will need version CryptStar-v1.5-Core257 firmw@re for CLONES found in "Starvi*w" firmw@re folder here.


You will need the GTromloader , v4.03_051005, (Starvi*w Software Uploader), found in "THE B0X" software folder of the link.

You will need version thebox_h20081204_455eE_apifound in "THE B0X" firmw@re folder here.


You will need version GTRom_Super_8.02e for THE SUPR B0X found in "THE B0X SUPR" firmw@re folder. (UFL = Unified Firmware Loader) here .

St@rview 4 - TheboxSuperUSB You will need version V1.07 for TheboxSuperUSB found in "THE B0X SUPR USB" firmw@re folder here.

Instructions SV4 Supr USB

To load the files just drag them on to a memory stick and then put the memory stick in the USB port at the back of the receiver.
Then press the menu button on the remote there you will see USB at the bottom of the screen.
Just highlight USB with the remote then you will see the (Box Super USB Bin file) appear on the screen.
Highlight "theboxsuperusb_v1.01_beta" with the remote and press the ok button then you will see the file start loading in to the Box.
Once that is complete, do that again but with the "TheBoxSuperUSB_BG_LOGO_080904" file.

Once that is done,

• Turn on the box, press menu and go to installation,
• Select correct provider i.e. NTL, C/W or TW
• Then automatic scan
• Once the channels are found, exit back to the blank screen
• Press menu then 1570,
• Go down to the bottom option and turn EMU to ON.
• Now exit 3 times and go to S*y Sports and let it update.

All firmw@re/loader can be found in the link at the end of my post marked EAMO'S LIBRARY.

Updating Firmw@re SV 1/2/3

Connect your box and PC with a Null modem cable and switch on the cable box and put it on STANDBY.
(The Starvi*w does not need to be connected to TV to update it with GTROM)

Open GTROM Loader software make sure that you set the correct COM PORT that matches the one that is being used

Make sure App file only is selected, then click b1n File & browse to the firmw@re where you downloaded it to on your PC.

Run the GTROM loader by pressing Download and you will see the % progress increase then Download completed message on your PC.

Wait until you see the DOWNLOAD COMPLETE p0p up on your PC before removing the NULL MODEM CABLE.

The Starvi*w will then reboot

Disconnect from PC and connect back up to the TV :)

Can't switch ports using PC keyboard

Make sure that your keyboard is connected to the keyboard port of the switch. The USB ports on the switch has pictures that indicates where the keyboard and mouse should be connected.

The hotkey combination is CTRL + ALT + SHIFT + Port no.(1,2,3 or 4) + ENTER

Note: "tap the keys one at a time and not at the same time"

Laptop will not connect properly

If possible directly connect the KVM cables to the laptop computer. Try to avoid connecting the KVM cables to a docking station. Also if your KVM has manual port selection buttons on the front of the KVM try holding that button for about five seconds when switching ports.

Only 1 light on leads work and only 1 coputer will work

That is the way it is designed, only the light of the PC you are controlling will be lit. Once you switch using the hotkeys, the light switches as well.

This guide is intended for use with the Eurovox but the equipment required is the same for flashing other boxes. The only differences will be with the relevant box firmware and its loader software.
1. Null Modem Cable ( available from here )
2. Serial to USB Adaptor ( available from here

The above adaptor assumes that you want to use a laptop to do the job; as most recent laptops do not have a serial port, you must purchase the adaptor.

The Serial to USB adaptor will come with a drivers disk. So install this before we go any further and follow on screen instructions.

Connect the adaptor to the USB port on the laptop. Connect one end of the the Null Modem cable to the Adaptor and the other to the serial port on the Eurovox.

Provided you have downloaded the correct version, proceed:

The file will have to be extracted. Use winzip or winrar for this procedure ( Very easy )

Ensure the Box is powered on. You can leave connected to the TV if you choose.

If you have your channels set up in Favourites we will back them up before flashing, although in some instances, the new update will not affect stored channels if your firmware is not too dated.

Anyway, go to the file which you extracted and start the application. ( It will be named UFL_MaxV_Kuro V........ ) Your first action will be to upload channel data. Select a name and a location for the file and save it. It is at this point you will be alerted if the box has connected with the PC. If it has not, do the following:

Go to Desktop / Right click" My Computer" / Select Properties / Hardware / Device Manager / Ports & Com Ports. Now select the next option to appear , in my case it's prolific serial to com port. Now select Port settings / Advanced / Change com port to 1,2,3 or 4 / OK / Exit .

Go back to the loader screen and you should now be able to communicate with the box.

Following channel data backup, you must now download the firmware to the box. Again, it is indicated on the screen and very easy to do. Once initiated, the box will display DNLD message and a progress bar will appear on the laptop screen. Allow to complete fully ! Do not disconnect until UPDATE SUCCESSFUL message appears on the screen. This can, in some cases, be 30seconds after 100% has been reached on the progress bar.

Finally, download your channel data and the operation is complete.

factory reset,
re scan,
go into the menu where you click on the set default key
switch on Emu
exit 3 times
wait for code to update
needs to be done after you have applied the fix,
And if that doesn't work put on Sky or Setanta orParamount+1 for a second, certain channels kickstart the process.

Hope this helps
