| Designed
to interface PC-compatible computers to SSI rotary shaft encoders
and linear scales, the DEVA001 absolute SSI (synchronous
serial interface) encoder interface card makes it possible
to measure absolute position, velocity and acceleration in
such wide-ranging applications such as robotics, co-ordinate
measuring machines and CNC machine tools.
Based on a custom-designed ASIC multi-channel
SSI controller, the card provides three independent input
channels. Each channel reads encoder position into a 32-bit
register at clock speeds of up to 2MHz. Input channels may
be configured to operate with a wide range of encoder types
and cable lengths. This enables both OEMs and end-users to
create fully featured and highly flexible PC-based measurement
systems.
A comprehensive software support library
is supplied, compatible with MS-DOS, Windows 9x/2000/ME/XP/NT4
and LabVIEW operating environments. Example source code and
a fully operational digital readout program clearly illustrates
the use and features of this library. |
