X64 Xcelera-HS PX8 Reference

When using the shaft encoder signals, the user can choose to connect to the opto-coupled inputs or
the RS-422/TTL inputs (which support a higher maximum pulse frequency). The imaging
application chooses which shaft encoder input to use via a board parameter (described following
the table below).
The following table describes the line trigger source types supported by the X64 Xcelera-HS PX8.
Refer to the Sapera Acquisition Parameters Reference Manual (OC-SAPM-APR00) for descriptions of
the Sapera parameters.
