Meilhaus Electronic ME-5100 cPCI, Manual, Page: 27 / 43

Duty cycle [%] = („duration of the first phase of the period“ [s]/pe-
riod [s] x 100.
4.1.2.2 Pulse Generator
In the pulse generator operating mode (FO = “Frequency Output”)
you can output rectangular signals with a variable duty cycle at fre-
quencies of up to 5.5 MHz and with a resolution of 1 tick. On the
ME-5100, all 4 pulse generator channels (FO_B0…3) are ad-
dressed as a
subdevices of type ME_TYPE_FO, sub-type ME_SUB-
TYPE_SINGLE. Each channel can be programmed independently.
The first phase of the rectangular signal is “high” by default. By
setting the ME_IO_SINGLE_TYPE_FO_START_LOW flag it is also
possible to start the output with a “low” level.
Note: An output channel can also be read back!
4.2 Streaming Operation Mode
4.2.1 Digital Input/Output
The programming of the timer-controlled input/output via FIFO is
carried out in the streaming operating modes. The 16
pins of sub-
device 0 are specified as inputs (subdevice of type ME_TYPE_DI),
while the 16
pins of subdevice 1 are specified outputs (subdevice of
type ME_TYPE_DO), all of these having the sub-type ME_SUB-
TYPE_STREAMING.
Please observe the ME-iDS manual and the ME-iDS help file (*.chm)
for the procedure. You can open both of these documents through
the “ME-iDS Control Center” or through the Windows Start menu.
