4. Event 1 and Event 2 inputs (and their return lines) are un-referenced
and are independent of any internal PCS power supplies or GND.
5. Each isolated Event input must be driven from a separate source.
6. Applanix can provide an events interface box for the event generators
(except for Type I and Type II described above). This events interface
box produces the proper PCS event input signals from devices that
output pulses ranging from 3.3 V to 12 V TTL. Please contact
Applanix Customer Support (page A-1) for more information.
