also make sure that Triggers are enabled by checking Async, Triggers, Enabled on the main menu as shown
below.
Configuring WaveCart
Start WaveCart by double-clicking the Icon on your desktop.
Make sure that all playback is halted and select
Tools , Program Options from the main menu, then click the
Hardware tab .
Figure 20: Go to the Hardware tab in WaveCart's Program Options
window to configure your USB-1024ls
Under the Trigger Settings heading, select "BSI Trigger Kit" in the drop down box as shown in Figure 20.
You’ll also see a setting for the Instacal Board # - this should correspond to the board number shown in Instacal
(this will usually be set 0).
Click
Done when you have finished.
You should shut down and restart Simian to initialize the new trigger settings. When Simian restarts you should
also make sure that Triggers are enabled by checking Async, Triggers, Enabled on the main menu as shown
below.
Connecting the USB-1024ls to Your Hardware
Now that you've installed and configured your USB-1024ls and configured Simian or WaveCart (or both), it is
time to connect the USB-1024ls to your outboard device(s). The pin-out specification is the same weather using
the USB-1024ls as a trigger kit or a closure* kit. Figure 21 shows a diagram of the pin-out structure. By looking
at the diagram in Figure 21, it becomes aparent that the physical pins on the USB-1024ls do not have a one-to-
one correspondance to what Simian/WaveCart see for each trigger/closure. For instance, the pins that correspond
to what Simian/WaveCart see as trigger 1 are pin 21, and a ground pin (the USB-1024ls has common grounding,
so any trigger can use pin 29, 31, 40, 9, 12, 15, 17, and 19 as a ground). When using your USB-1024ls as a
Trigger Kit, each pin will be wired to a dry relay closure (as on a satelite receiver's GPO/GPIO connector) or a
mechanical switch (as on a GO/START/PLAY/STOP button on a console). When using the USB-1024ls as a
closure device, each corresponding pin will be wired to your outgoing device (as in a TTL GPI/GPIO on a
console, transmitter, or other outboard device).
NOTE: See the * note at the bottom of this document regarding the TTL "closure" functionality of the USB-
