Percentage numbering systems for display and entries. When percentage is selected, all en-
tries are still made in Decimal numbers.
h) VT-52 Compatible Display: When this toggle is enabled, the BS-ANA will use special escape
sequences to clear the screen (
tion the cursor (
entire screen to change any value, so it can save a good deal of screen redraw time if you
have a compatible display.
i)
twelve bit resolution: When toggled ON, the output resolution will be twelve bits. This works
out to a resolution of one part in 4096. With a 0-10 volt output, each step will be .00244 volts.
If you are using 12 bit resolution analogs, you must carefully account for the locations and
number of output channels you are using. Each 12 bit resolution input takes 1-1/2 eight bit
channels. The BS-ANA wonÕt let you set the first address for a 12 bit analog to any address that
can be evenly divided by three (0, 3, 6, 9, etc.). This is because it uses these bytes for storing
the least significant four bits of the next two 12 bit resolution channels. Any 12 bit resolution
channel that is addressed at an address that can be divided evenly by three plus one (ad-
dresses 1, 4, 7, 10, etc.) will need to have the previous address sent (or burnt into the Eprom)
so that its lowest four bit nibble isnÕt lobbed off. Any 12 bit resolution channel that is addressed
at an address that can be divided evenly by three plus two (addresses 2, 5, 8, 11, etc.) will
need to have the previous two addresses sent (or burnt into the Eprom) so that its lowest four
bit nibble isnÕt lobbed off.
j)
Output to Test & Adjust: This command is used to set the output address that will be used by
the 'Test Output', 'Set Analog Endpoints', 'Force output to a Value', Ôset Min/Max/forced
using keypadÕ, and 'set PowerOn Defaults' commands. If the output address selected is one
of the sixteen on the BS-ANA, then an arrow will appear next to it on the screen. In the exam-
ple screen above you can see this arrow pointing to output #7, which happens to be ad-
dressed at address 8. Since some of the adjustments can affect channels that are only trans-
mitted through the DMX-512 and Z-Brick outputs, the address can be set to anywhere be-
tween 0 and 255.
k)
Test Output: When toggled to ÔTest One OutputÕ, the single output selected by the 'Output to
Test & Adjust' command will be ramped up and down. The ramp time is about 5 seconds. The
time the output stays at each extreme is set by the 'Test Dwell Time' command. When tog-
gled to ÔTest All OutputsÕ, all of the outputs will be ramped between their two extremes. The
ramp time is still about 5 seconds. The time the output stays at each extreme is set by the 'Test
Dwell Time' command.
l)
auto Ease-In: When enabled, this feature will keep all of the selected channels from jumping
at a high rate of speed if:
a)
Incoming frame number received through the SmartBrickNet jumps more than five
frames. (This is typically caused by discontinuous time code being received by the
Smart Brick Brain, or when the Smart Brick Brain jumps to a different show.)
b)
The DMX-512 data starts being received.
c)
The DMX-512 signal drops out for more than a second.
d)
An output is forced to a specific value.
e)
One or more outputs are put into or taken out of the internal test mode.
f)
At boot up as the outputs assume their default values.
This command allows you to select the amount of time any output will take to ramp from
one extreme to the other and which outputs will be using the Ease-In feature. The range of
time available is:
0)
Ease-In is disabled
1)
1/4 second
2)
1/2 second
3)
1 second
4)
1-1/2 seconds
5)
2 seconds
6)
2-1/2 seconds
