Ttl Inputs And Outputs; Common Signals For All Function Modules; Single Signals - Addi-Data APCI-1710 Technical Description

Functions of the board
9.3

TTL inputs and outputs

At the connector ST5 of the ACPI-1710 are further I/O, GND and Vcc of
the PC available. These signals must correspond with the TTL level and be
treated carefully in order not to damage the board if other signals shall be
connected.
With the cable FB8001 the board can be connected through the connector
ST5 to the peripheral.

9.3.1 Common signals for all function modules

The signals PA0 to PA7, PB0 to PB7 and PC0 to PC7 are connected with all
"function modules". They are available for max. one "function module"
(e.g. "TTL I/O) available.
Example: Only the function module No. 4 (FM4) is programmed with the
function TTL I/O. The signals can be set as inputs or outputs.

9.3.2 Single signals

2 TTL inputs and outputs (I and J) are available for each "function module".
These can be used only together with function module TTL I/O.
