no signal between 2 x Mini IP Video 12G linked by 2m Cat6

Hi,
We just received our 2 Teranex Mini IP Video 12G hoping that interconnecting them *directly* with a Cat.6 (F/UTP) cable, first trying w/ a new *2m cable*, would work out of the box.
Sadly, that doesn't work and with just don't know what we might be doing wrong with a setup so simple

Here is the setup in detail:
* A camera is connected to the first Mini IP Video via the SDI IN connector
- we know that the signal is locked because the front led switches to solid green and we can watch the stream if we connect a monitor to one of the SDI OUT connector of the same Mini IP
* Then we connect a new 2m Cat. 6 (F/UTP) cable between the "1G Ethernet PoE+" connector of the first unit to the second Mini IP Video and connect the SDI monitor to the SDI OUT of the second unit.
- The results is that we don't get any stream on the monitor and the front led of the second unit stays solid white while everything stays the same on the first unit (front led solid green).

We know that the network physical link seems to be ok thanks to the ethernet led on the back of both units and we're pretty confident on the settings regarding the direction of the signal (we set the switch 1 down on the first unit and leave it up on the second)

Would really appreciate ,any help on what might be wrong with our setup please ?

The final setup would be identical except that the 2m cable would be replaced by ~100m cable...but that a story for another day i guess
Thanks

Well i'm not completely familiar with the Mini IP Video units..
But a few things to consider::

• both units need an IP address and get linked from 1 IP to the other IP, Ip must be in the same subnet range
• I'm not sure if the unit even will stream video by the IP port.. The IP Port might be only for configuration.. And you need the Fiber connection for video
• IF the IP port supports streaming it will only do HD. The units work with TICO codec which does a 4:1 compression. So 12G becomes 3Gbit of data 6G becomes 1.5Gbit of data And HD will go under the 1Gbit.. Which is the limit of the IP port..
• Without PTP timing generator in your network it could take anything up to 30 minuts for the units to sync up and display video. THat why often is choosen for a High end fiber network switch that has such capabilitys build in..

So to sum up.. Just trow a cable between it and expect it to work like Extron, Kramer, Crestron boxes over CAT is not the case with these devices..
I haven't looked at the manual of this unit.. But i guess there is a step by step plan how to configure and link these units, and what is needed to connect 2 of them.

Hi Xtreemtec,

Thanks for your reply !

Oh ? I didn't get that reading the manual (http://documents.blackmagicdesign.com/T ... eo_12G.pdf), that's why i didn't configure any IP adress on the units indeed.
Will try to rectify that ASAP and let you know how it went

I'm not a native english speaker but reading p5 of http://documents.blackmagicdesign.com/T ... eo_12G.pdf, i can't imagine how that wouldn't be the case quiet frankly

IF the IP port supports streaming it will only do HD. The units work with TICO codec which does a 4:1 compression. So 12G becomes 3Gbit of data 6G becomes 1.5Gbit of data And HD will go under the 1Gbit.. Which is the limit of the IP port..

HD is fine with us actually.

Without PTP timing generator in your network it could take anything up to 30 minuts for the units to sync up and display video. THat why often is choosen for a High end fiber network switch that has such capabilitys build in..

If that's indeed the case, i wish that was mentionned on the manual. I hope i'm wrong here but iirc, i haven't read anything about that on the manual, at least when the setup is as simple as a direct ethernet cable between 2 units :-/

So to sum up.. Just trow a cable between it and expect it to work like Extron, Kramer, Crestron boxes over CAT is not the case with these devices..
I haven't looked at the manual of this unit.. But i guess there is a step by step plan how to configure and link these units, and what is needed to connect 2 of them.

That was the hope and TBH, nothing on the manual squash that. I know cause i've read it before buying the units

So i guess my only hope is that the issue is either related to the lack of ip adressing for the 2 units and/or the long delay to lock the signal.
Time to do some testing
Thanks !

Okee i dig into the manual now.. So yes it is possible to send HD over the 1Gb port.. Cool.

You have to configure 1 device as Input and the other as Output device by the software.

The direction of the signal, for
example a video input or output, depends on whether you have set the unit as a source or
destination. You can find more information about this setting in the ‘setting Teranex Mini IP
Video 12G as a source or destination’ section in this manual.

Network switches and PTP timing protocol>>
By the way it is adviceable to always use a network switch. Because you can also connect a laptop for configuration, router for DHCP etc..

About Network Switches
When connecting to a network switch, we recommend using a managed switch with PTP
precision time protocol and E2E end to end enabled. This type of network switch lets you
change the configuration to suit your network requirements, for example prioritizing traffic for
smoother data flow and improved reliability.
If you are connecting to a network switch with VLAN functionality, ensure VLAN is disabled.
Non managed network switches can still be used. However, without the IGMP management
systems enabled, a destination unit may be getting traffic from several sources, thus exceeding
its port’s bandwidth.

So by default they are on DHCP.. Running a 1:1 cable between them without ANY configuration.. The units are trying to get a DHCP lease from a router that is in the network.. Which you dont have because you have no other devices connected in the straight cable network.

Network Settings
Your source and destination units will have their network settings set to DHCP by default. DHCP
lets your network automatically identify each Teranex Mini IP Video 12G with their own IP
addresses and lock each unit to the network’s PTP clock, so you won’t need to change any
settings and each unit will be automatically recognized by your network.
If you want to set the IP address manually on each unit, you can change the network settings
via the Blackmagic Teranex Setup administration software, or by using an optional Teranex Mini
Smart Panel, if attached. For more information, refer to the ‘Settings’ section in this manual.

Dipswitch 1 can be used to set it as Source or Destination. (off = Destination, on = Source)
But you can also use the Software to configure.
After that you need to link a Source to your destination device. This can also be done by the software or by the Smartpanel front display if you have them (They are optional).


The manual is pretty clear how to setup.. Don't want to copy the whole manual.. But i think you have enough pointers now to get it running.

Still it is no Kramer, Extron Video over CAT setup.. Those are most off the time a 1:1 setup and not real ethernet but only use CAT cable for video..

These Teranex devices are much smarter and do a Streaming video over network. So you could distrubute this video trough a huge network to multiple receivers.. But also be compatible in the future with other brands of IP video devices.. Which is the strength of this system.. Take a little bit more configuration then a 1:1 CAT video set tho..

Good to hear
Ok, we did the ip setup on each unit and made sure that they end up on the same network but still no signal on the destination unit despite the fact that we let the test run for an hour and half :-/
Honestly, according to the manual, this setup should be plug and play...

You have to configure 1 device as Input and the other as Output device by the software.

That's exactly what we've done via the front switch n°1 on the source unit. And we double checked that this setting was correct by configuring each unit via the app

By the way it is adviceable to always use a network switch. Because you can also connect a laptop for configuration, router for DHCP etc..

And that may on of our problem. I'll double check but i'm pretty sure that we don't have a managed switch with support for PTP
Most of our switches are standard Catalyst switch (Cisco 2960 for example) and they don't support that protocol (https://en.wikipedia.org/wiki/List_of_P ... mentations) as far as i know

Reading the manual, i didn't get the impression that PTP was an hard requirements for setting up Terranex mini IP. Is it a requirement ?

So by default they are on DHCP.. Running a 1:1 cable between them without ANY configuration.. The units are trying to get a DHCP lease from a router that is in the network.. Which you dont have because you have no other devices connected in the straight cable network.

Yep, that's obvious (even if not stated explicitely) and i should have get that :-/ Thanks for pointing this out
Sadly, configuring the IP settings manually didn't resolve the issue

The manual is pretty clear how to setup.. Don't want to copy the whole manual.. But i think you have enough pointers now to get it running.

You're right that the manual is short but pretty readable.
The thing is that something must have been left out it because our basic setup (you can't get more basic that a direct cable between the 2 units) isn't wokring
I mean, now that we've checked the ethernet cable, the ip settings of each unit, the input video (front led is green) and the destination of the stream is OK, what more could be configured/checked ?
I really don't know

The product sure seems to be one with a lot of potentiel but i wasn't expecting that the basic setup wouldn't work out of the box :-/

Anyway, thanks a lot for your help so far ! Really appreciate it

Have you tryed to stick a network switch between them?? Might be that 1:1 cable does not work while a Cross is needed.. But stick a gigabit switch between them and watch what happens..

Did you ever figure this out? Im having the exact same problem
