I know, you were sad that you missed my PowerPoint presentation at Rane’s InfoComm Booth in Orlando a few weeks ago because you had to golf. Or was it Disney World, or drinks with your industry pals? Or was it because your boss sent those other co-workers from the Sydney office?
Either way, don’t fret. I recorded the PowerPoint presentation without the convention center background noise. Continue reading
Here are two short impromptu videos from the InfoComm 2013 show floor.
The first quickly reviews the four HAL products – the HAL1 through HAL4.
HAL Evolves at InfoComm – Video #1
The second video gives a brief overview of the HAL1x’s four EXP expansion devices – the newest is the EXP7x acoustic echo canceller. It also reviews the new Web Controls feature for any HAL device. (Boy, I sure sound nervous – I had to “wing it” and without a script or the makeup department!)
HAL Evolves even more at InfoComm – Video #2
To exceed 100 meters (300 feet) distances between daisy-chained (yes, daisy-chained) EXP devices, you need an unmanaged, Gigabit Media Converter – either single-mode or multimode. The data pulsing through Rane’s Expansion Bus is not IP (Internet Protocol) and contains no MAC Addresses. Thus, you cannot connect it to an Ethernet network in any way. No Ethernet switches allowed. You must have a dedicated connection from the HAL1x to all subsequent EXP devices – up to 32 EXPs maximum.
Here is a very simple and inexpensive multimode fiber media converter we found on Amazon. The maker is TP-Link. Model number MC200CM. You need two of these – one at each end, of course. Plus the cable. We bought the blue cable, although, we’ve heard that the green cable sounds better? You’ll have to judge for yourself. Often terminating the cable is the biggest challenge – a favorite task for IT folks.
We’ve also successfully tested the Startech MCMGBSC055 which works great.
We do NOT recommend the Trend Net TFC-1000MGA – it does not work with our bus. This is where the “unmanaged” requirement fits in. If the device tries to inspect “Ethernet” packets to, for example, keep track of MAC Addresses that come and go, this is not compatible with Rane’s Expansion Bus. Our bus contains no MAC Addresses and no IP Addresses, nothing. Some but not all Managed converters allow you to turn off such packet inspections. If you’re working with IT networking folks, make this unmanaged requirement clear to them to avoid speed bumps on the Expansion Bus.
New Halogen 3.0 supports 5 new HAL System devices and includes the new 512 x 512 audio channel Expansion Bus.
The new Expansion Bus surpasses any and all Ethernet-based control and audio transport solutions (e.g., CobraNet, Dante, and yes, even Ethernet AVB) since it allows HAL to do things none of these do – see this post for details. For Expansion Bus details, click here.
