1. Short-circuit proof single I/O only. Total current should be limited to less than 25 mA.
2. Keep voltages on Digital I/O below Maximum Input Voltage to prevent CEBO-LC from damage. This is
also true, if CEBO-LC is unpowered.
3. Protective circuit of Digital I/O on the screw terminals differs from that on the Sub-D jack.

1. Keep voltages on Trigger I/O below Maximum Input Voltage to prevent CEBO-LC from damage. This is
also true, if CEBO-LC is unpowered.
2. Protective circuit of TRG terminal uses lower resistor value than normal Digtial I/O.
3. Keep the total number of edges below this limit, to avoid missing edges.
4. Input frame consisting of Analog Input 0.
5. Time interval from edge of Trigger signal to ADC conversion start signal for the first analog input in the
InputFrame.
6. External timed data acqusition.
7. Hardware timed data acquisition with Trigger set to rising edge input mode.
8. Hardware timed data acquisition with Trigger set to alternating output mode.
