CP2000H DLP IP address

[Alban Birch]

Hi
We're trying to revive an old Christie CP2000H, it seems that the IP-address of the TPC and DLP don't match. As we don't Know the IP of the DLP,is there a way to reset the DLP IP or is there a Emergency IP?
Thanks

The TPC and the DLP addresses NEVER match...they have to be on the same network (or reachable via routing) but unique addresses. The TPC has to know what the TI's IP is so it knows where to send/receive instructions.

The TI portion is reachable via the dedicated TI program though you'd still need to know its IP address.

I remember this happening to me many years ago. I believe I used the TI Control program to connect to the projector via Serial to read the IP address. Or you could use Wireshark to monitor the traffic from the projector and discover the IP address.

I agree with Mike that Wire Shark could be used. A while back I wrote a batch script that looped through a range of IP addresses and pinged them. I was then able to find equipment on the network in our San Luis Obispo office so I could do some testing. It SEEMS that there would be a simple IP address scanner available that would ping each IP address in a user specified range, look at the MAC address of the response, and give you the manufacturer name (from the OUI portion of the MAC address) and the IP address. Anyone know of such a utility?

Hi, indeed, use a laptop/PC with serial port or a USB to serial adapter cable and check Serial Port on the TI DLP Control software. You will be albe to login and find the IP of the DLP, 100% tested.

Steve you're completely right, what I meant is that the DLP-address registered in the TPC is not right and we can't communicate with the DLP.
I think I have the an ICP and Enigma Control Programm, but don't have the login.
Mike and Harold could explain how that would work with monitoring the Network Traffic?
Thanks

ICP/Enigma isn't the same program as the S1 TI program (it is similar but decidedly different).

Harold, "Angry IP" will ping all IPs in the range desired. One can then do an arp -a to see the MAC addresses of the various IPs.

Serial was definitely a way for S1 projectors (and even some S2. FWIW, Christie's Default IP for S1 TI boards is 192.168.206.010, so that is a place I'd look (you'd need to get your laptop on that range first, of course). What is the IP of the TPC? Sometimes that can give a clue. For instance, if the IP of the TPC is 10.1.1.191, I'd look at 10.1.1.151 for the TI board as that would follow one of the popular schemes (Cinedigm) that was used.

SUCCESS!!!
Thank you very much guys. Connected via Serial with the Series 1 DLP Programm, changed the IP of the DLP to the one registered in the DLP and was your uncle.
The IP was 192.168.21.91 and the one registered in the TPC was 192.168.255.110, so none were the default ones.
Thanks again.

[Steve Guttag]

I'm surprised. The default Christie TPC IP is 192.168.206.110...so they moved the 3rd octet to 255...fine...move the 3rd octet on the TI boards to 255 and leave the 4th alone...but I'm sure they had their reasons (probably a conflict).

Basically to summarize what others have said, if you don't know the IP address of a projector or IT board, going in via RS232 is the first line of attack. The newer Barco cinemacontrollers use a USB jack for RS232 access, so a USB to RS232 adapter, plus a USB A male to USB A male cable (to hook a laptop that does not have a DB9 jack for RS232) are essential items for the toolkit these days.

Some new devices are configured in the factory to ask for a DHCP address by default, so carrying around a cheap router with a built-in DHCP server can be helpful. Connect the unknown device and your laptop to it, and then look at its DHCP allocation table in its web UI once everything has booted up.

And as Mike recommends, Wireshark often works if you have to find out an unknown IP address and every other line of attack has failed. However, you need to connect as a straight shot with a crossover cable (a patch cable will work 90% of the time, but not 100%) to the device rather than through a switch or router, because that's the only way to be sure of your laptop actually capturing the packets coming out of the device with the unknown IP address if it's not sending out broadcast messages.

look at the MAC address of the response, and give you the manufacturer name (from the OUI portion of the MAC address) and the IP address.

Wouldn't this only tell the manufacturer of the device's network interface, not the manufacturer of the board or system (in this case TI)?

I haven't seen a USB serial jack that I know of. The small Barcos have a USB port on the CCB but I think it is a real USB port, you just need the device driver (which should be on Win10 but I have had to install it a few times). If that is actually RS232 hiding in a USB jack... this is news to me.
Haven't studied the CCB on the 10 or so Barco laser projectors I've installed to say what jacks are present.
