iDR-32 healthcheck from PC (firmware, connection, settings)

I’ve got this iDR-32 unit without surface.

It responds to pings to 192.168.1.1 when connected to second Ethernet port as documented in the iDR guide https://www.allen-heath.com/content/uploads/2023/06/iDR-16-32-48-64GettingStartedGuideAP7445_4.pdf

The problem is that iLive Editor hangs while trying to connect to the iDR-32 no matter which version of the software is used Windows or Linux.

Resetting network card with 15 second switch doesn’t help.

I have no idea, if it is iLive Editor software problem, MixRack hardware problem or MixRack firmware problem. It could be that the iDR-32 firmware is too old, and no version of available iLive Editor are able to communicate with that. But I am speculating. It would be nice to be able to diagnose what is wrong with this MixRack (or not) step by step.

There is the manual that describes TCP/IP protocol for firmware v1.9 https://www.allen-heath.com/content/uploads/2023/06/iLive-TCPIP-Protocol-V1.9.pdf but I have no idea which firmware is this iDR-32, and the document doesn’t list any commands/packets to send to query firmware version.

Maybe there is a more technical protocol to query device features and test it works? Any help would be appreciated.

Are you connecting a computer directly to the network port on the iLive, or are you connecting these devices to a larger network with a router and network switch?

I only ask because the most common consumer grade router address is 192.168.1.1 which would cause a conflict with the iLive’s default address of 192.168.1.1. You may need to change the router’s default network address in this case.

If you are connecting the computer directly to the iLive’s network port, are you manually assigning a static IP address for the computer’s network port? Computer network ports are typically set to DHCP by default and if this is the case, without a router/DHCP service running on this simple network, the computer is going to default to a 169.254.x.x network address. If this happens, the computer and the iLive are not on the same network segment which would easily explain why the software cannot connect with the iLive. Assigning the computer a static IP address in the 192.168.1.X with a 255.255.255.0 subnet mask (but not 192.168.1.1 because that is used by the iLive) should solve your connection issues.

I beleive if the software can establish a connection with the iLive, it will tell you if there is a firmware mismatch. I believe it also will tell you what the current iLive firmware version is so that you can correct the mismatch. (I have an iLive, but it’s been so long since I set up the network, or changed the firmware that I am a little foggy on the exact operation/functionality).

Laptop is connected directly to the 2nd network port of iDR-32 MixRack without any routers or switches.

Yes, the Laptop IP is set manually to 192.168.1.10 with the mask 255.255.255.0

Moreover, in WireShark I can see a packet coming from 192.168.1.1 with something like “BYE” inside. I need to find out how to post it here.

If I had a working iLive, perhaps comparing handshake packets could tell where things go wrong, but it is just a speculation.

Something I will add, at the Laptop check for these 3 things.

1, no VPN running.

2, no Firewall active.

3, make sure any Virtual Box Ethernet adapters are disabled(if you have VB installed).

Any one of these can block an iLive connection… BTDT.

If I could have a script that does firmware check, all these misconfiguration issues and version mismatches could be ruled out. I am pretty sure there is a packet coming back from the MixRack, and the control port 51321 is open there.

There is some alternative software that seems to be able to control iLive devices GitHub - bitfocus/companion-module-allenheath-dlive-ilive · GitHub but it doesn’t guarantee the result either.

Mixingstation is way easier to try and should connect to most versions and give you an error if it cant.

Its possible the DSP is toast. Theres a common failure there was a service bulletin to isolate the 24V supply from the other voltage supplies. If that wasnt done and it got humid and dusty its likely the higher voltage flashed over and killed the DSP.

If you type the mixrack IP in a browser you should get a 404 page that says “iDRLive HTTP Server Error” that will confirm you have the mixrack IP correct.

You can change the IP thru the URL

http://IPAdddress/Setup.html note thats case sensitive and must be used exactly as typed after the /

You can also see the mixrack software version

Have you tried the dipswitch reset? Turn all 4 switches on. Boot the rack. Wait a couple minutes. Power down. Turn all 4 off. Power up.

Also how far do you get in the progress bar connecting?

Connecting to http://192.168.1.1 through a browser just made the browser hang connecting. I am going to try it again to see if it the browser fails with connection time out after 90 seconds like it happens when IP:Port doesn’t exist. Need to try http://192.168.1.1/Setup.html as well.

Versions and features - Mixing Station Docs - I am going to try it, thanks.

If everything above fails (after going through cycles of power off, power on and waiting at least 2 minutes before try) I also want to scan open ports with nmap.

Tried different combinations, this is the last one. It would be nice to get some manual, or another way to confirm that these steps should do something.

I have a copy of the CPU reset doc. Send me a pm with your email and I can get it sent to you.

All attempts to connect to the MixRack’s http://192.168.1.1 from Firefox, curl and Mixing Station failed.

curl and Firefox hangs indefinitely. TCP connection is established successfully, but nothing is being sent in reply to standard HTTP request.

Mixing station is connecting..

but then failing with timeout during handshake.

Now I am going to do port scan, to see if there is anything alive on other ports.

Did that. Nothing changes.

Then the CPU is dead. Note the CPU will still answer in the DSP is bad so the units a total loss based om your info

Is it dead CPU or could it be damaged firmware chip? Something initializes network card and makes it accept connections. I guess that without CPU nothing will accept TCP connections, and there are 3 ports open.

Connecting to 51325 hangs too, but connecting to 51321 spits out some data. So something is alive there.

If there was a description of the protocol, I could send some commands there. Even if the web server is dead, may be the part that controls DSP isn’t.

I had to reset the network settings in my iLive this weekend before a gig, so the process is fresh in my mind!

Just to triple check - you are turning off the iLive, then pressing the network reset button (the small hole with the recessed button near the network ports) and holding that button in while you turn the Mixrack back on, and continue holding the button in for at least 15 seconds after reapplying power?

If so, and the Mixrack (at ip 192.168.1.1 after the reset) is still no responding to connection attempts from the iLive Editor, or Mixing Station, then I agree that something has failed in the unit that is preventing the connection from being established.

Yes. Did exactly as described in the manual.

The connection is established as shown by curl earlier, so network card seems to work perfectly. But there should be something beyond network card to send reply over the connection, and it is not clear what it is.
