502P board is specifically used for laser marking. Using PCI bus, the marking is fast and stable. With MarkingMate software, it can achieve a variety of combinations. Support the control of lamp pumped , semiconductor ( end-pumped and side-pumped ) , and CO2 laser marking system. It supports analog galvanometer and supports most of engraving applications as well, like static marking on flat, small spherical surface or small camber surface with complex graph. Some reserved I/O pins could connect with rotary axis device to perform rotary axis marking. 502P is a truly good C/P value card for general laser marking application.
 Dimension: 119.9 x 91.0mm
Support Windows 98/2000/XP/Vista/Windows 7
2 channel high speed, precision 16bit DAC for galvanometer control (Default)
OptionalOptional 3rd and 4th 16 bits high speed precision D / A channel; can be controlled as a YAG laser power, or
as a dynamic focus control, or other applications that require D / A control aspects(Only 502P + board has this
function)
Default has 19 switching outputs (TTL level, DO12 to DO15 have photo coupling isolation), they can control auxiliary
equipments of laser marking control system, like laser power, acousto-optic power, rotary axis, XY table, solenoid
valve etc
OptionalThere are another optional 5 channels switching outputs (TTL level, DO19 to DO23 have photo coupling
isolation) , they can control auxiliary equipments of laser marking control system, like laser power, acousto-optic
power, rotary axis, XY table, solenoid valve etc(Only 502P + board has this function)
OptionalThere are another optional 8 switching outputs (TTL level, DO16 to DO23 have photo coupling isolation) ,
they can connect with input signals of pedal switch and other auxiliary equipments(Only 502P + board has this
function)
Default has 16 channels switching inputs (TTL level, DI0 to DI15 have photo coupling isolation), they can connect with
input signals of pedal switch and other auxiliary equipments
Default has 1 PWM signal, the frequency and duty ratio can be set by software, used for acousto-optic modulation and
CO2 laser control
Default has 1 32-bit hardware timer, can be worked with software to perform mark on the fly
Note: The functions with “optional” word is only for 502P+ board in above statements, the normal 502P board doesn't
support it
Warning: 502P doesn’t support hot-plug, or the board will be burnt out
Static Marking
502P could support complex graph editing and import with MarkingMate software to fulfill general laser marking requirement. The excellent C/P value of 502P approaches customers.
Non-flat surface marking (Small spherical surface, camber surface marking)
502P with MarkingMate makes static marking on small spherical and camber surface without deformation through marking compensation to ensure marking quality. The application of this function without any other hardware to make small spherical surface, camber surface marking possible and easy
Rotary axis control and marking
502P has many TTL signal I/O ports which supports the pulse and direction signals of rotary axis device to perform complex rotational marking with MarkingMate, especially for cylinder and disk marking
Automation marking
502P supports conditional and procedural marking with automation control signal ports which support input and output signals of marking to fulfill the need of automation
