9025 INPUT/OUTPUT PIN FUNCTIONS
Parameters 0 to 4 of Class 25 control the functions of the five input/output pins on the Parallel I/O
Connector. (See Table 4-4) When the parameter value is set to zero (0), or the parameter is not defined,
the default function of the I/O pin is selected as shown in Table 4-4.
To change the functions of the input/output pins change the respective parameter for the pin (see
Table 4-4) to the values shown below. The input functions are selected by negative values as shown in
Table 4-5. The output functions are selected by positive values as shown in Table 4-6.
For example:
To change the function of pin 4 to select the film transfer rate (falling edge selects 24
function parameter (class 25 parameter 2) to value –5.
To change the function of pin 4 to output a pulse at the start of each internal 6 Hz cycle, set the pin 4
function parameter (class 25 parameter 2) to value 23.
