Medialab Documentation

MM32BRK (REV-B)

Identification

Rev B is a green color PCB with white silk screen medialab/mm32brk.pcb REVB 031505

Connectors

• MM32 ribbon cable (2)
• Power (1)
• Analog Inputs (16)
• Analog Outputs (4)
• PID ANA-IO (1)

Known Problems

• Some power supply decoupling caps on pg3 of SCH have the wrong orientation, populated on PCBs correctly

LED Indicators

• 4 groups of LEDs indicate the presence of power and the state of the fuses.
• Normally the LEDs on either side of the fuse should be dark – when a fuse blows these LEDs should be visible.
• LEDs adjacent to the power connectors indicate the presence of power

Assembly Variations

FUSES : the fuses socket may be populated with a shorting wire, a fast blow fuse, or a resistors which will act like a slow blow fuse.
