EA OPT-OPTO8I8O INPUTS AND OUTPUTS
All EA KIT240 graphics kits are available optionally
with 8 digital inputs and 8 outputs (EA OPT-
OPTO8I8O). All the inputs and outputs are isolated
from the rest of the electronic components as well as
each other. The connection is made via 16 different
screw-type terminals. At the same time the same
outputs (non-floating) can be connected at the 20-pin
plug-in connector (J120) via 5V CMOS level.
Note: The logic circuitry is designed for slow
operations; in other words, more than 3 changes per
second cannot be easily executed.
Note: The optocouplers invert the input logic (all
inputs open: port macro 255). It is advisable here (in
the power-on macro, for example) to use the
"ESC Y I 1" command to evaluate the inputs
inversely (all inputs open: port macro 0).
8 outputs
Each line can be controlled individually using the
"ESC Y W" command. A maximum current of 10mA
can be switched per line.
8 inputs
A voltage of >4V starts an internal port macro. However, the inputs can also be queried and evaluated
directly via the serial interface ("ESC Y R"). When the 8 lines are combined, up to 256 port macros can
thus be addressed. Each of these port macros can change the contents of the screen or switch an
output, thus enabling a wide range of control functions. To create the port macros you need a PC and
the EA DISK240 floppy disk. You will find a more detailed description on page 6. The automatic port
query can be disabled by means of the "ESC Y A 0" command.
APPLICATION EXAMPLES
Direct voltages of 5..35V can be applied at all 8 inputs. Voltages of over 4V are recognized as high
level, while voltages of under 2V are low level. Voltages of between 2 and 4V are undefined. The
polarity is insignificant.
The collector and emitter of a transistor is brought out at the
screw-type terminals as the output. Each output can switch
a maximum of 10mA. Ensure the polarity is correct, and note
the transistor's load-dependent voltage drop of 0.6..5V.
Note: The negative pole of each screw-type terminal can be
interconnected by closing the solder straps LBI1..8 and
LBO1..8. These solder straps can also be connected to
system ground GND (solder 0Ω strap R
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).
