Tuning Adapter (High-Split) Converter Problem

We just got the new, required Vecima HSC Tuning Adapter to be used with my Roamio.  It had been working fine with the Cisco TA, but they are making changes that require the HSC.  Of course I wouldn't be posting if everything worked fine.  It isn't working, and the TA Diagnostics won't show anything.  They sent a tech out who couldn't resolve, and another one is now scheduled.  He'd tried both split and passthru config (left the latter), but neither worked.  Note that they had not changed the cablecard;  just the TA.  I'm glad to hear its working with a Roamio, and it may just be the firmware level.  I can't see the firmware version due to the TA diagnostics not displaying.  Was the firmware update something they had to manually push?

All 3 of my HSC Tuning Adapters started a reboot loop at 7:59PM (Arizona Time) Wed, 04/24/24
Is anyone else seeing this behavior?
I called the CableCARD hotline, they said they could see the rebooting happing, and my area had a very high call volume for Issues.

Had some trouble getting logged in here to post an update, but a second tech that had Cable Card / Tuning Adapter experience was able to get everything to work.  Primarily a lot of reboots and waiting.

Note:  latest TA (Vecima HSC) firmware version: eTR version 1.8.0  Although I originally couldn't get the TiVo to show any TA diagnostics, the original was on 1.4 I think they said.  Everything has been working great for about a week.  The TA does get pretty hot;  I've got it on the top and separated from the other electronics.

Note also, the correct wiring is cable into TA, and then out to the TiVo (pass thru), and not split.  Apparently, the new TA has the capability to re-modulate channels (impressive), and therefore the TiVo needs to get the cable from the TA.  

The techs were very nice and cooperative.  One remote tech was helpful in provisioning and scheduling the on-site techs.  Any chat, general help desk, or retail store people; however, are clueless.  The best you can hope from them is to ship you the new TA and/or schedule an appointment with the right techs.  The retail store people (especially the store manager) are generally rude and very put out that you want something other than what they are trying to sell you.  You can get the new TA shipped to your home, and I think if you wait long enough and reboot enough (both TA and TiVo), I think the TA will eventually download the latest firmware.  You shouldn't need a new cablecard;  I don't believe they have anything "new" cablecards anyway.  Even if it isn't working initially, you'll want to leave the TA on overnight (cable in and power) so it can get the latest firmware downloaded.  It didn't appear the techs could do anything to force a TA to update itself.

I did a self install. Coax passes though the TA, USB hooks up ( they're still using the old mini-USB or whatever that thing is), power on, and make the activation call. The Edge was working before the call ( or old data from the Cisco was being used?).

Funnily enough, the Roamio worked fine without the TA but not with it. During the activation call they had me reset the TA after doing something at their end. The Roamio appeared to work fine after that so I hung up. However it only worked until the TA finished rebooting (kind of slow I guess), so no golden bullet there. Looking at the Roamio devices page I could see the tuning adapter status cycling between present and not present. Reboots of either or both boxes didn't help. The USB connection wasn't working between them. 

I split the coax into both the old TA and the new TA and used the old one while the new one downloaded a firmware update. About 24 hours later I swapped to the new TA and the Roamio showed a solid USB connection status. All the channels were working. 

Which all just confirms what has been said here already about Roamio TA's. I'm glad I knew what to expect, since Cox was mostly clueless. No need to send techs out. It just needs to sit, connected to Cox, probably after activation, long enough (maybe 24 to 48 hours, maybe less) to update its firmware.

I'm in Phoenix and the solution worked for me after several Cox telephone techs including level 2 were unable to get it working! 

I have Roamio.

In my case, with the new Vecima TA connected, I lost all channels. The blue light kept flashing on the TA. I discovered, accidentally, if I unplugged the USB cable end from the TA… I got my Non SDV channels back but, still blue light flashing and still no SDV channels and still the TiVo cycled between saying: ‘yes TA connected/no TA connected!’

L2 tech ordered a new TA for me. Arriving Friday.

I then went online and searched and luckily… I found this discussion!

I had already restarted both the TiVo and the TA a couple of times but I did it more and left the TA connected & about 18 hours later, the TA blue light was steady! I checked the TiVo and it still was cycling, saying: ‘yes TA connected/no TA connected!’
I waited & restarted both TiVo & TA again.

Finally, after approximately 24 hours, I tried connecting the USB cable again & this time I did NOT lose my non-SDV channels but, TiVo still did not say TA connected. Said No TA connected. At least it was no longer cycling!

A couple hours later I ck again & now TiVo says TA connected!
I still did not have SDV channels so, I restarted the TiVo yet again and then Voila!… I have all my channels; SDV & Non SDV!

I called Cox L 2 back again and told him about it and they said that they would look into it because they were never told anything about waiting for a firmware update. I was already activated from the night before when they enter all the information regarding the new TA.

Thanks so much for posting this information!
