INPUTS AND OUTPUTS
The EA KIT160 is supplied with 8 digital inputs and 8 outputs (5V CMOS level, non-isolated). The
connection is made at the 20-pin connector J120.
8 outputs: Each line can be controlled by means of the
„ESC Y W“ command. The maximum current per line
is 6mA. Output 8 (PIN 17) is used to switch the LED
backlighting (ESC Y L n1). If this output is required, the
LED backlighting can be separated from the output
via the solder strap LB 8 and switched on
permanently.
8 inputs: The inputs can be queried and evaluated
(„ESC Y R“) directly via the serial interface. Each
change of logic level (0V or 5V) at the inputs can start an internal port macro. When the 8 lines are
combined, 256 port macros can be addressed. Each of these port macros can change the contents of
the screen or switch an output. This allows a wide range of control tasks to be carried out. To create the
port macros, you need a PC and the floppy disk EA DISK240. You will find a more detailed description
of this on page 6. Automatic poll querying can be disabled by means of the „ESC Y A 0“ command.
Note: The logic circuitry is designed for slow operations; in other words, more than 3 changes per second
cannot be easily executed. If an input is open, this is evaluated as high (approx. 100 kOhm pullup).
Application examples:
DEFAULT SETTINGS
After power-on or a manual reset, the registers shown here
are set to a specific value.
Please note that all the settings can be overwritten by creating
a power-on macro (normal macro no. 0).
