TTL Output 1 and TTL Output 2
In this section, you will find the parameters related to TTL Output 1 and TTL Output 2.
Polarity
As was the case for TTL Inputs (and for the same reasons) the TTL Outputs are
implemented through optical isolators. And as was the case with TTL Inputs, the terms
“Active” and “Inactive” are used for TTL Outputs as well.
The
Polarity
control allows you to specify which TTL Output State will be asserted as a
result of the “Condition” (described below).
Condition
The
Condition
specifies which signals and behaviors the Mach-DSP will be observing,
before asserting of the respective TTL Output. Possible conditions are:
Never (the TTL Output is placed in the opposite state specified by
Polarity
)
Always (the TTL Output is placed in the exact state specified by
Polarity
)
If X-axis servo is Ready
If Y-axis servo is Ready
If both X-axis and Y-axis servo are ready
If either X-axis or Y-axis servo is ready
If Power Amplifier is enabled
If Servo board temperature is greater than
Amount
If X-axis coil temperature is greater than
Amount
If Y-axis coil temperature is greater than
Amount
If X-axis coil temperature is greater than
Amount
If X-axis scanner is being exercised
If Y-axis scanner is being exercised
If either X-axis or Y-axis scanner is being exercised
If either X-axis or Y-axis coil temperature is greater than
Amount
If X-axis Position Error is greater than
Amount
If Y-axis Position Error is greater than
Amount
If either X-axis or Y-axis Position Error is greater than
Amount
If X-axis Velocity is greater than
Amount
If Y-axis Velocity is greater than
Amount
If either X-axis or Y-axis Velocity is greater than
Amount
(As explained above in the TTL Input section, the “exercise” actions will only have an
effect if exercising has been setup in the scanner tuning, using the parameters on the
Pangolin-only tab.)
