* Event 1 In and Event 2 In are optically isolated digital inputs.
* Inputs (and their return lines) are un-referenced and are independent of internal
POS MV V4 and POS MV V4-1 power supplies and GND.
* Inputs can be controlled from an external 5V TTL-level source capable of
supplying a minimum of 5 - 10 mA of sourcing or sinking current.
Event Notes:
1. PCS Event 1 and Event 2 are optically isolated inputs and for proper
operation require a current flow of 5 - 10 mA between the “Input“ and
“Input Return” terminals.
2. Event 1 and Event 2 inputs can be driven by two types of the external
event generators:
• Type I event generator with an output capable of supplying
(sourcing) a current of 5 - 10 mA. For Event 1, the output
must be connected to the Isolated Event 1 (pin 2) with the
