I replaced the Christie IMB S2 in my Solaria 4220 with a Dolby IMS 2000. It was relatively straight forward getting everything set up but I am currently struggling to get the IMS2000 to send the signal to the Jnior to pulse the relays that control my Kelmar dimmer (just down, mid, up). Any guidance on how to set this up?

Make sure you have your IP and port address properly configured. the IMS2000 should have an JNIOR device file (Set up in Device Manager) that should take care of the port for you and leave you with just the IP address.

When issuing commands, I recommend always adding a \w (wait) command on each and when configuring your cues, make sure that if they are text cues that binary was left checked (I have not worked with the JNIOR but have worked with the IMS2000 so I don't know the specifics of what the JNIOR is looking for). Also make sure your commands match what the JNIOR is expecting to receive (perhaps test them with your computer using a utility like PuTTY.

While the IMS2000 is 'Dolby' branded, the software base is Doremi, and using a JNIOR with a Doremi is usually not complicated. Integ has a setup document specifically for using JNIORs with Doremis.

http://www.integpg.com/downloads/documentation/AppNote_Doremi_Configuration.pdf

In general, JNIORs can be addressed by using raw ethernet or serial commands, but Doremis also offer a dedicated JNIOR driver. Now, it may be that whoever installed the JNIOR with the Christie IMB-S2 changed some defaults, and you may need to adjust some of these settings back to their defaults. While the IMB-S2 also offers a JNIOR device driver, it may not necessarily have been setup and used that way.

First, make sure the JNIOR driver is installed on the IMS2000 in device manager. Also, Rick from Integ can be phoned and will help you with any questions and guide you through.

Then be prepared for Bruce turning up here and suggesting an upgrade from the JNIOR 310 to a 410 (hi Bruce) ;-)

Haha, Carsten, yeah the 310 is not recommended for new installations but 310/410 the difference in this case will only be performance.

Rick can probably address the configuration quickly for you. If you send a quick email to support[at]integpg.com you should get a response promptly from one of us (even on a weekend). I just don't have the application experience to be definitive in this case. Kevin is lurking around here someplace.

Never hesitate calling the office, leaving a message or emailing for support. It's like early Maytag, we don't end up needing to provide support all that often and actually look forward to it (makes us feel needed). ;-)

Hey guys.

Im lurking... Now to rise from the deep and post a quick response.

First a thanks to Carsten for the link to the application note.

To add, I would suggest trying to reboot the Dolby. I have heard that sometimes a Dolby or Doremi needs to be rebooted after adding or updating a JNIOR device. Its worth a try.

Funny you mention that. A brief history... You see it all started a long, long time ago... Ok enough about that. The up side for our customers is that work related topics get discussed a lot more outside of work.

Okay, maybe we can get into the backstory as an extra at CinemaCon.

I know this is a 310. One of the advantages of the 410 is that there are diagnostic tools which are worth knowing about. The 310 had an IOLOG function for digital I/O and the 410 certainly has that and it is more precise. The IOLOG function on a 410 also allows you to see communication over the AUX serial port which can be great for debugging.

This is a case where you might want to run a network sniffer. Well the 410 is always sniffing the network port and capturing packets. You can generate a capture file using the NETSTAT command at any time to capture recent network traffic leading up to the moment. The resulting PCAP file can then be downloaded from the JNIOR and it will open right up in Wireshark (https://www.wireshark.org/).

You can establish a larger capture buffer and set filtering both on the way into the capture buffer and out into the capture file. You can also search and filter in Wireshark of course.

There is a promiscuous mode which can capture traffic not targeted for the JNIOR but that is usually thwarted by the network switches. We keep a bunch of older hubs around for that purpose as they pass all of the traffic to the JNIOR.

So I know this is sort of an advanced thing. For those of you that can handle it, it can really help diagnose communications with the rest of the world be it Doremi or whatever. And if you are ever adventurous enough to want to develop an interface to a different protocol it can be invaluable.

We would be happy to demonstrate the function and/or train anyone interested. Some information can be found on jnior.com. Search the Knowledge Base for "NETSTAT".

I replaced the Christie IMB S2 in my Solaria 4220 with a Dolby IMS 2000. It was relatively straight forward getting everything set up but I am currently struggling to get the IMS2000 to send the signal to the Jnior to pulse the relays that control my Kelmar dimmer (just down, mid, up). Any guidance on how to set this up?

So I thought that I would circle back on this since the issue seems to be relatively common. There is or was an issue with the Dolby IMS where it would send random bytes for the JNIOR's password to the JNIOR. Dolby has supposedly taken care of the bug but perhaps some of you can confirm. We still get calls and we are not sure if they are using the latest Dolby IMS release or not.

The work-around is cumbersome but has resolved the issue in the cases where we have suggested it. The steps are:

1. Remove the JNIOR from the IMS.
2. Reboot the Dolby IMS
3. Add the JNIOR back.
4. Reboot the IMS.

What we don't know is if you should reenter the default JNIOR username and password. We have heard that it is shown correctly but needs to be manually entered to properly update the fields and to then become functional. Naturally if you are using different credentials with the JNIOR you will have to edit the default. Maybe someone close to this issue can relate their experience.

I don't believe that a JNIOR that has been functional with the IMS starts then to fail. I think this only involves the initial configuration for JNIOR communications. Again, you guys can set me straight.

At any rate, don't "struggle" with the JNIOR or ever sit there in a state of confusion. Just email us (support[at]integpg.com works) and we will be happy to help you out or answer your innermost questions. We have been known to respond at all hours even on holidays. Although there is no guarantee of that, we do care and try.
