THE DIP SWITCH IS NOW DEPRCIATED, ALL FUNCTIONS IT SERVED ARE NOW DONE VIA WEB EDITOR.  The ONLY function is serves now is to identify the unit as 16 channel instead of 8: if only 8 channels are showing up in the editor that means you did not switch DIP channel #4 to on. Mid 2021+ Devices not NOT have this switch

    Please note: Device MUST be powered by the eurorack power, it is Not USB Powered.

    Basic Usage instructions:


    Voltage Select switches:  Independent for each channel. Does NOT affect MIDI/I2C data

    Slider LED color: To change the LED color, simply remove the cap and rotate the square LED 180s.  Do NOT force the LED back in, it should slide in easily, may require wiggling.


    Power Header: Standard 10pin power cable, there is NO polarity for this connection.  It can be connected either way.  the USB5V header is not used in the euro configuration of the device

    MIDI Out Header: This is a 4 pin header but only 3 or 2 connections need to be used.  To connect to a DIN cable, either GND, 5 (to pin 5, current sink/aka -), and 4 (to pin 4, current source/aka +) should be used.  For internal module to module connections, only pin 4 and 5 should be used.  The ground pin is only for the shield in a midi cable, it is never connected on a midi input and isnt necessary for the short module to module lengths

    I2C Header: 3 pin header to connect to other I2C devices in your rack, this is an unbuffered connection so cable lengths should be as short as possible (20cm/6" recommended).  There are 4.7k pull up resistors on this connection

    Connector for Expander: This connects the XVI to the I/O expander.  The cable is attached to the expander.  Note the keyway below the 1 in on the part, the connecter will ONLY connect one way


    Firmware update procedure:  Connect the Mini USB to your computer, power up the module and press the blue reset button on the back of the module twice (quickly).  A new drive will appear on your computer, simply copy the firmware file to that drive (it will give you a warning about copying a file without properties).  The drive will disappear once the file is copied and the module will reboot with the new firmware.
