Position Synchronized Output (PSO)

You cannot use a sine wave encoder with the -MX1 multiplier option as an input to the PSO. The -MX1 option does not generate emulated quadrature signals.

This output signal is a 5V TTL signal which is used to drive an opto coupler or general purpose TTL input. This signal is active high and is driven to 5V when a PSO fire event occurs.

Output	5 V, 16 mA (max)
Maximum PSO Output (Fire) Frequency	12.5 MHz
Output Latency [Fire event to output change]	25 ns
