MCI manufactured the JH24 series with Tuchel I/O. Each Tuchel contains 4 channels of I/O. Custom cabling will need to be made in order to interface your machine with your setup. We suggest Redco. To save you the hassle of ordering custom cabling, we now offer a DB25 conversion option that is priced less than most custom cable would cost. This makes interfacing your Mara Machine with A/D converters or consoles a breeze, and helps increase resale value.
