DESCRIPTION
ICS's Model 8013 Ethernet <-> Parallel Inter-
face Board provides a 128 line digital interface
that can be used to interface devices with a large
number of digital signals to the computer via an
10 or 100 Mb Ethernet network. The 8013's
high-power TTL level signals can easily
drive small relays or other logic elements.
In a typical application, the 8013 is located
inside the device chassis and is powered by the
device's +5 volt power. All digital signal connec-
tions are on a 150-pin connector at one end of the
card. An RJ-45 header on the other end of the
8013 contains the Ethernet signals. Applications
include controlling switching matrices, displays
or large signal arrays.
Versatile Digital Interface
The 8013's digital interface is configured with
commands over the network. The configuration
commands permit the user to designate the 128
data lines as inputs and/or outputs in 8-bit byte
increments, connect bytes into strings, set data
polarity, data format, and handshake modes. The
user can set bytes as inputs. Input signals are
tristated and are pulled up by 33 kohm resistors to
5 Vdc. The inputs are ideal for reading switches,
TTL and CMOS signals.
The user can set the output lines to his desired
values and save the current configuration in the
8013's Flash memory. The saved configuration
becomes the new power-on configuration. At
power turn-on, the Digital I/O lines are initially
tristated and then set to the saved configuration.
A Stable signal is asserted after the digital I/O
lines are configured to enable external logic or
relays.
Data Transfer Methods
Data transfer capabilities between the com-
puter and the 8013's digital interface depends upon
the link to the 8013. When linked to
inst0
the user
can access all setup commands and control the
digital interface by individual bits, by bytes, or as
strings of data values to multiple bytes as shown
in Figure 2. When linked to
inst1
data is transpar-
ently transferred to the digital interface.
• Bit commands set or reset specific bits in a
byte or query a bit’s status. New pulse commands
let the user pulse single or multiple output lines
at the same time.
• Byte commands set all 8 bits in a specific
byte or read data from a byte.
• String transfer commands send strings of
data characters to one or more output bytes to
make a multi-byte output word or read a string
of data from one or more input bytes. The user
designates these bytes as inputs or outputs when
configuring the board.
