DIGITAL INPUTS AND OUTPUTS
All EA KIT160-7 series provide 8 digital In- and 8 outputs (5V
CMOS level, grounded).
8 outputs
Each line can be controlled individually using the "ESC Y W"
command. A maximum current of 10mA can be switched per
line. For more power use an external transistor or MOSFET.
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.
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 left open, it is logical
high (internaly pulled-up via 100 kOhm).
IN- AND OUTPUTS VIA OPTOCOUPLER (EA OPT-OPTO16)
Optionally all In- and Outputs are isolated via
optocouppler circuit (EA OPT-OPTO16 only). The
connection is made via 16 different screw-type terminals.
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.
Output is a "open-collector" circuit with collector (+) and
emitter (-) of a NPN transistor. A maximum current of
10mA can be switched per line.
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
Note: Logic will be inverted by optocouppler circuit (all inputs left
open: port-macro #255). The command "ESC Y I 1" inverts
logic back again (all inputs left open: port-macro #0)
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).
