Appendix A
Auxiliary I/O
The XL laser auxiliary I/O functions are provided by the port on the back panel.
Auxiliary functions provided are remote triggering, quadrature output and
analogue output. The functions are selected and configured by means of four dip
switches.
Auxiliary I/O connector kit
An auxiliary I/O connector kit is provided with the XL laser kit to enable users to
configure cable connections for use with the XL laser’s auxiliary I/O port.
The cable can be configured to the user’s own application and requirements by
using the pin connections shown in the auxiliary I/O pin table.
It is recommended that a good quality shielded cable is used, for example
shielded twisted pair cable 28AWG (7/36).

When constructing a cable, the cable’s screen should be connected to the
connector’s body. If twisted pair cable is used, the RS422 quadrature signals
should share the same twisted pair, i.e. A and A/, B and B/.DIP switch settings.
