Basic Usage instructions:

Front:

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

Rear:

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 UPDATES:

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.

CURRENT FIRMWARE VERSION: 1.02
