Description
|
The GL Series midi LOGGERS from Graphtec are a whole new breed.They come equipped with 10 channels already, but are expandable to 50 or even 100 channels. There are two locations for plugging in our 10, 20, and 50 channels input modules, so you can create just the right system.
Modern conveniences such as Ethernet and USB 2.0 interfaces are included, along with a PCMCIA flash memory card port, so you can easily get the data out of your GL450 and transfer it to your computer. Data are normally captured into the GL's large internal memory, at rates selectable from 100 ms to 1/hour! You can record for hours, days, or even weeks with the 2 MS memory.
High Isolation
We built in 125 VAC RMS / 350 VDC isolation on all the analog channels, for a few reasons. First, it means you can hook up your GL midi LOGGER without the normal worry about ground loops, providing you more flexibility and control. Second, it just makes good technical sense to isolate the inputs, and is even a nice safety feature. Few products in this class provide this kind of isolation as standard...or even as an option!
