The first phase of the rectangular signal is "high" by default. By set-
ting the ME_IO_SINGLE_TYPE_FO_START_LOW flag it is also possi-
ble to start the output with a "low" level.
In combination with the plug-on board ME-5002, 4 additional pulse
generators (FO_D0…3) are available, addressed as one subdevice.
Note: An output channel can also be read back!

The programming of the counters is done in operation mode „Sin-
gle“. A counter device of type 82C54 provides three 16-bit coun-
ters. Each counter is accessed as a subdevice of type
ME_TYPE_CTR, subtype ME_SUBTYPE_CTR_8254. Note the order
of operation as described in the ME-iDS manual and in the ME-iDS
help file (see ME-iDS Control Center).
4.1.3.1 Standard Operation Modes
The counters can be configured independently of one another by the
function
for the following 6 operation modes (a
detailed description of the modes can be found in the ME-iDS man-
ual):
Mode 0: Change state at zero
Mode 1: Retriggerable „One Shot“
Mode 2: Asymmetric divider
Mode 3: Symmetric divider
Mode 4: Counter start by software trigger
Mode 5: Counter start by hardware trigger
Please read picture 13 on page 23 for the wiring of the opto-iso-
lated counter signals.
