Barco CCB Factory Reset For DP2K-32B

[Rick Cohen]

I am working on a Barco DP2K-32B projector. While attempting to update the IP address of the CCB board with Communicator, the CCB lost communication with the laptop and I can't regain communication with the projector. I only changed the last quartet of the IP from .52 to .36 so it isn't like the whole IP was changed. Did it brick? The board is 13 years old, and is original from when the projector was installed back in 2013.

I tried rebooting the projector, and reseating the board. Still no communication. Is there a way to factory reset the CCB to it's original IP address? It's hard to believe the board would brick, I've updated the IP on other CCB boards in the past and never had this happen before. The replacement cost for a new CCB is $3,500. I did contact Barco support, and they haven't come up with a solution yet.

Has anyone else experienced something similar to this?

I'm sorry to say that I have, many times. The router chip on a mk. I Barco CCB is notorious for biting the dust.

My suggestion would be to attempt a connection to the CCB via RS232 as the next step. If your laptop doesn't have a DB9/RS232 port (which, if it's significantly younger than the projector itself, it won't), you'll need a USB to RS232 adapter. This one works, and the driver needed for it is built in to Windows 10 and 11, meaning that it should be plug 'n play. Choose serial as the connection method in Communicator, as so:

There is no option in this screenshot, but with your adapter in place, it should show you one, likely called COM3. Note that once connected, everything will seem a lot slower than when connecting to a projector via Ethernet: this is normal.

Once connected via serial, the telltale sign that the CCB's router chip has kicked the bucket is that when you go to the communication settings tabs in the Communicator app, all the fields are blank. If this is what you see, then your options are either working around the projector having lost Ethernet communication (e.g. by using a US Converters or IP2SL to send API commands), or buying that $3.5K replacement CCB. But if you see an IP address, netmask and gateway, but maybe you miskeyed and now it's in the wrong subnet, you can correct this using the RS232 connection and then all should be good.

I use this one as it has reliably worked with every device I have connected to https://tripplite.eaton.com/keyspan-...dapter~USA19HS

Does the Keyspan one play nice with Windows 11? That's the model adapter I have always had but have not tried it on the W11 machine. I still carry a W7 machine for the older stuff since that's the newest most of the old stuff seems to like anyway. Its really fun when you get some really old software that only offers you the first 3 com ports but that's where the Keyspan app is nice you can select which port you want and see which ones are in use or available.

It seems to be a total crap shoot with USB to serial adapters. Some will be recognized by your computer, but not the RS232 device you're hooking up to; others vice versa. I only mentioned the one I linked to above because it's worked fine with both my previous field laptop and my current one, W10 and W11, and it connects OK both to a Series 2 Barco CCB and a CP650 (the only two devices I need to make a laptop to serial connection with regularly). I'm sure that the Tripp-Lite one is fine as well, but I haven't tried it.

[Ioannis Syrogiannis]

My two cents: I have reliably used the Tripp-Lite adaptor with CP650, Barco CCB, on the back of Sony SRX-R320 (with a null cable). But I have never had Windows 11 on a laptop used on the field. Probably because I am not on the field, or my field is rather narrow, nowadays.
If I was to guess, I would say it works just as well.
I have heard good words about the FTDI chipset (FT232RNL) as well. I went towards the USA-19HS adaptor after reading great things about it on the old Film-Tech forum. No regrets.

P.S.: If you change the IP of the controller and, after restarting, it changes again to a random IP, you have a cinema controller that is not good.

USB-serial adapter with Windows 11, you can use it normally simply by installing the additional driver. It is a shame, though, that it is nearly 20 years old and was missing from the built-in Windows 11 drivers.

I have had the very rare experience with the Barco CCB where it reverted to its factory default IP.
Could it have changed to 192.168.100.2? Have you tried connecting using that IP?

In the past, Barco's touch panel (communicator) must have been supplied along with the equipment. Is that not available?
It supports both serial and Ethernet connections, so it is sometimes useful when servicing the DP series.
I still keep the Barco touch panel in my car, and Barco still provides updates.

The Keyspan / Tripp-Lite / Eaton USA-19HS has worked fine in Windows 11 for me with the CP650 and other legacy devices.

If an RS232 connection is not available, one could try to connect to the projector at its factory default IP address in the event the board reset to that IP. IIRC it's in the 192.168/16 subnet (198.168.100.2 that the previous poster listed sounds familiar) but I do not recall the exact IP offhand. An IP scanner on a laptop in a wide enough subnet should be able to find it.

If the projector has a V2 CCB, one can turn the projector on from cold, let it boot for a few seconds then immediately turn the power switch off and then immediately back on again to reset the IP to the factory default. This seems to be more a bug than an intended feature of the V2 CCB but can work in a pinch (or cause chaos if there's utility power issues or a malfunctioning UPS on a screen).

Like Leo, I've seen my share of early V1 CCB's bite the dust, but those from 2012 and later seem to have been more reliable. If this happened, a clue is that the projector will take much longer than usual to fully boot up.

[Leo Enticknap]

Good point: the ICP will boot up in the usual timescale (to three solid lights and a blinking light on the left), but if there has been a CCB hardware failure, the projector's tail light will continue to blink for up to around ten minutes before it goes solid. I can't remember if the keypad ever lights up with this CCB failure mode (router chip goes bad): I've a feeling that it doesn't.

An IP scanner on a laptop in a wide enough subnet should be able to find it.

It should, but that could take a long time. If you want to find the IP address by brute force and cannot make a serial connection for whatever reason, my method would be to run a patch cable directly between my laptop and the CCB, start a Wireshark capture going, and then power cycle the projector. When the CCB's router wakes up, it should spew a number of packets into Wireshark, and you can find the IP address from one of those (or, in the case of some other devices, see it ask for a DHCP address, give up after a timeout period if there is no DHCP server to provide one, and then auto IP itself with a 169.254.X.X / 16 address).

The factory default IP for a Series 2 Barco CCB is definitely 192.168.100.2, but I can't remember if the default netmask is 24 or 16.

Does the Keyspan one play nice with Windows 11?

Yes there are official drivers for it.

Just bear in mind I've encountered Keyspan serial adaptors which would refuse to connect to a cinema processor - when my own identical adaptor on the same system (same driver) would. So there must be different revisions of them around.
