TTL Out
The state of the TTL OUT lines can be set from the TTL Diagnostics dialog box.
Checking the box associated with an output bit designation sets it’s level high (+5 V; bit
ON). If the box is left unchecked, the output bit is low (0 V; bit OFF).
Versions & More box
This box reports a variety of kinds of ancillary information, including the installed DLL
versions, selected device driver and its version, DMA buffer space allocated, and the
number of PCI cards found. The Controller version is also reported. This information
would not ordinarily be required by an operator, but could prove invaluable when
contacting PI’s Technical Support department for assistance.
Not all of the indicated information is reported in early versions of the software.
