Tom’s Tech Blog: Hate Flash? We’ve Got Options

Comrex products like ACCESS, BRIC-Link, and STAC-VIP each serve a rich web page that functions as their main user interface. For a variety of reasons (that were perfectly sound at the time) these pages were designed with the Adobe Flash tool. But Flash has gotten a (not entirely undeserved) reputation in recent years. Its constant need […]

Tom’s Tech Blog: Broken Wifi Adapters got you down?

          With our ACCESS portable and LiveShot portable codecs, we ship a a high gain Wifi adapter, the Edimax EW7811-UAC.

Tom’s Tech Blog: When the backup becomes the primary

It was nice to read this Radio World blog about Westwood One’s operations during the Rio games. We’re used to seeing big-time broadcasts like this done via ISDN, with IP codecs being relegated to the backup role. But it seems the script has flipped, and IP is now considered reliable enough to be the primary […]

Nifty BRIC-Link Accessory from the UK

Much like the US has a “special relationship” politically with the UK, we at Comrex work closely with our UK partners, Vortex, on special projects. Their latest one is the VX-4901 panel. It turns a BRIC-Link II codec into a full-featured intercom system, allowing the easy connection of ten sites and connection of a speaker […]

Tom’s Tech Blog – NAB 2016 is a wrap

It was great getting out to NAB (my 29th consecutive!) and talking about everything we’ve been working on all year. The VH2 Hybrid garnered a lot of attention, as well as the new 4.0 CrossLock firmware for ACCESS/BRIC-Link. But what was that shiny black object? Could it be a preview of things to come? It […]

Tom’s Tech Blog – Verizon XLTE is terrible…except when it’s awesome

If you’re a LiveShot/ACCESS Verizon LTE user in the US, your wireless modems will likely have a choice between the “standard” LTE band 13 (700MHz) and the “XLTE” Band 4 (AWS-1700/2100MHz). When I say your modems will have a choice, I mean it literally, since you can’t easily choose in software.

Tom’s Tech Blog – A secret about Comrex Connect International Modems

I’ve griped plenty in the past about the wireless situation in the USA, where each carrier uses completely different LTE bands, so no universal USB modems exist. But here’s a secret: The Comrex Connect modem designed for International use includes virtually every LTE band in use in the USA.

Tom’s Tech Blog – Here comes the VH2

Debuting at NAB this month is the VH2, an audio telephone “hybrid” for VoIP. Hybrid is in quotes because it’s not doing the traditional phone line cancellation (not required in the VoIP world), but functionally it acts like a traditional studio telephone interface.

Tom’s Tech Blog – Thoughts On Security

Several stations using Barix codecs for STL have been diverted to receive an adult-oriented stream, then locked to that stream this week. Many theories are floating about the sophistication of the attack, but I’m a fan of Occam’s Razor on this. I’ve seen enough web interfaces unprotected out there that I think this attack employed a simple lookup on an Internet-of-Things directory site, then login via default password.
