Function description

1 Function description
Via the 50-pin header, TTL signals can be connected to the board.
Signals PA0 to PA7, PB0 to PB7 and PC0 to PC7 are connected in parallel to all four function modules of
the board. To avoid malfunction, the "TTL I/O" function can be loaded only in one function module.
Features:
•
For each function module 3 ports (A, B, C) with 8 digital inputs/outputs each (set as inputs after the
reset)
•
For each function module 1 Port (D) with 2 digital inputs/outputs (set as outputs after the reset)

1.1 Board versions with "TTL I/O" function

The I/O specifications of the different board versions are available in the Technical Description of the
APCIe-/CPCIs-1711 or APCI-/CPCI-1710 (see PDF links).

NOTICE!
In case other signals are connected, these have to correspond to
the TTL level to prevent the board from being damaged.
Please also note that the ports are not optically isolated and that
the board may be destroyed due to external voltage peaks!
NOTICE!
The "TTL I/O" function can be used with every version of the
APCIe-1711, CPCIs-1711 or APCI-1710.
