The PSGs of all Matrox Solios eCL/XCL
1
boards support 5 V tolerant rotary
encoders, except fot the PSGs of the standard-speed Matrox Solios XCL
dual-Base/single-Medium board
(66 MHz), which supports 3.3 V tolerant rotary
encoders.
❖ Note that an external source must be used to power the rotary encoder (for
example, the computer’s 5 V power source).
For each PSG, you can program two auxiliary signals as quadrature input signals.
One to carry the first bit, and one to carry the second. You can toggle quadrature
decoder settings using the MIL-Lite function MdigControl(), or by modifying
the DCF file.
User-defined signals
Any auxiliary signal can be configured as a user-defined signal. You can route any
input signal that meets specifications to an auxiliary input signal (or auxiliary I/O
signals in input mode) configured as a user-defined signal; your application can
then interpret this user-defined signal as required.
You can specify the on/off state of a required output signal and have the PSG
generate and route it to an auxiliary output signal (or auxiliary I/O signals in
output mode) configured as a user-defined signal; your application can set the
on/off state of the signal based on some analysis.
To inquire and control user-defined signals, use the MIL-Lite functions
MdigInquire() and MdigControl() with M_USER_BIT_...
