vmusb

Determines, along with the options -inverto1 and -latcho1 the behavior of NIM output O1. This can be any of the following values: busy, trigger, busrequest, eventdatatobuvffer, dgga, endevent or usbtrigger.

Inverts the sense of the O1 nim output.

Latches the O1 asserted when the condition that asserts it is met.

Along with the options -inverto2 and -latcho2, controls when the NIM O2 output is asserted. This can be any of: usbtrigger, vmecommand, vmeas, eventdataobuffer, dgga, dggb, or endevent.

Inverts the sense of the NIM O2 output.

Latches the state of the O2 NIM output when the condition that would assert it is met.

Together with -inverttopyellow and -latchtopyellow determines when the top Yellow LED of the VM-USB is lit. This can be any of the following values: ofifonotempty, infifonotempy, scaler infifofull, berr, vmebr, or vmebg.

Inverts the sense of the top yellow LED.

Latches the top yellow LED in the on state when the condition is met that would light it.

Together with the -invertred and -latchred options controls the when the red LED on the VM-USB front panel is lit. This can be one of the following value: trigger, nimi1, nimi2, busy, dtack, berr, vmebr or vmebg.

Inverts the state of the red LED.

Latches the red led on when the condition to light it has been met.

Together with the -invertgreen and -latchgreen, determines when the green LED is lit. This can be one of the following values: acquire, stacknotempty, eventready, trigger, dtack, berr, vmebr or vmebg.

Inverts the condition that lights the green LED.

If true, the green LED is latched in the on state once the condition that would light it is met.

Together with -invertbottomyellow and -latchbottomyellow determines when the bottom yellow LED is lit. The value of this option can be any of the following values: notslot1, usbtrigger, usbreset, berr, dtack, vmebr or vmebg.

Inverts the condition that lights the bottom yellow LED.

Latches the bottom yellow LED in the lit state once the condition is met to light it.

If this is true the two scalers A and B will be read by the stack in which the vmusb is module is put. The A scaler is read first followed by the B scaler. See -scalera and -scalerb below which define when each scaler increments.

This option is ignored unless -readscalers is true. If -incremental is true, scalers are cleared after they are read. Note that since the VM-USB has no mechanism to atomically read and clear scalers, counts can be lost between the read and clear.

Determines the condition that increments scaler A. This can be one of the following values: dgga, nimi1, nimi2 or event.

Determines the condition that increments scaler B. This can be one of the following values: carry,, nimi1, nimi2 or event. The carry value means that scaler B is incremented when scaler A overflows. This allows both scalers to be combined into a single 64 bit scaler that is incremented by the condition defined in the -scalera option.

Sets the source if the start for DGGA this can be one of: off, nimi1, nimi2 ,trigger, endofevent, usbtrigger, or pulser and default to pulser

Sets the source if the start for DGGB this can be one of: off, nimi1, nimi2, trigger, endofevent, usbtrigger, or pulser and default to pulser

Sets the width of the the A/B dgg output. This defaults to 1 which is the minimum width (see the VMUSB manual for the units of this value.

Sets the delay of the A/B dgg output. This defaults to 0. The delay value is a 32 bit integer that is spread out across the VM-USB delay and coarse delay registers. See the VM-USB manual for more information.
