Please Note:
This device uses PSIpower and has NO POLAIRTY on the power header, it can be installed EITHER WAY
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
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 F8R to the I/O expander. The cable is attached to the expander. Note the keyway at the top of the part, the connecter will ONLY connect one way
FIRMWARE UPDATES:
Current Firmware Version: 2.03
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) and thats it. The drive will disappear once the file is copied and the module will reboot with the new firmware.
IMPORTANT NOTE FOR USERS THAT DO NOT HAVE A RESET BUTTON ON THE DEVICE OR ARE RUNNING FIRMWARE VERSIONS LOWER THAN 1.0 (It says on the box), Please contact Michigan Synth Works for update procedure
