Configurable general purpose ports (16 control pins)
These ports represent the bulk of the GPIO functionality. Each of these ports can be configured
as follows:
Digital In (3.0V TTL logic - Low: 0 VDC - 0.8 VDC; High: 2.0 VDC - 24 VDC)
Digital Out (3.0V TTL logic - Low: 0V DC - 0.4 VDC; High: 2.4 VDC - 3.3 VDC)
Analog In 1K, 12V (using external 12 VDC power source)
Analog In 10K, 12V (using external 12 VDC power source)
Analog In 10K, 24V (using external 24 VDC power source)
Analog In 1K, self powered (pin feeds required voltage through pot or switch to common)
Analog In 10K, self powered (pin feeds required voltage through pot or switch to
common)
Rotary Encoder (requires 2 pins and a common)
Raw (all modes available, software configurable)
Clock signals on pins 6-8.
High current output ports (4 ports)
Each high current port provides 11.5VDC at 0.5A. High current outputs can be configured for
straight logic (on/off) or PWM (Pulse Width Modulation) operation.
Fault relay
A single system relay is configured for supervising project faults. This Form C relay provides
1A contacts and is activated when the front panel fault LED is illuminated, which indicates a
muted condition. Muted conditions could indicate many things, including the following:
A firmware/Role mismatch
A voltage rail malfunction
XDAB Fault Policy exceeded
Network or Network Synchronization lost.
The behavior of the fault relay is summarized below.
Event
Fault relay action taken
Role running
Pin 25 is connected to pin 12
Role stopped
Pin 25 is connected to pin 13
Unit or system muted
Pin 25 is connected to pin 13
Project halted
Pin 25 is connected to pin 13
Project erased / no project loaded
Pin 25 is connected to pin 13
Power off
Pin 25 is connected to pin 13
