Auxiliary Input/Output connector kit
An auxiliary I/O connector kit is provided with the XL laser kit to enable users
to congure cable connections for use with the XL laser’s auxiliary I/O port.
The cable can be congured 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 screen should be connected to the
connector body� If twisted pair cable is used, the RS422 quadrature signals
should share the same twisted pair; for example A and A/, B and B/�
