1. General description
The HICOMSCAN HDG-1111 DATA GRAPHIC SYSTEM is a high per-
formance, high stable tablet digitizer designed to read
digital data from any kind of drawings. It is most suited
to an input device through which graphic data are input to
a computer, and is usable in many other application areas.
Features:
(1) ~igh accuracy
A stylus pen or cursor has an accuracy of ± 0.01", and
thus ensures a highly accurate operation regardless of
the tablet dimensions.
(2) Lightweight
Compact structure with a built-in controller requires
a smaller space.
(3) Easy maintenance
A built-in microprocessor checks the hardware to permit
easy maintenance.
(4) Absolute digitisation
Origin remains held where it is even if a cursor or pen
is lifted off the tablet.
(5) High stability
Electromagnetic induction feature permits stable opera-
tion impervious to external factors such as wind, tem-
perature, humidity, noise or vibration.
(6) Noise resistance
Noise resisting characteristic enables the system to
be used as a computer terminal.

To plug in the connector, hold the connector shell by hand,
turn the shell until it fits into the socket marked STYLUS
on the tablet, and then push it straight into the socket.
To disconnect, hold the shell by hand, and pull it straight
toward you. Do not pull out the connector by puiling on
the cable.

Stylus replacement procedure
(1) Pull out the ·existing stylus
with a nail clipper or hair
tweezers.
( 2)
(3)
Insert a new stylus properly
into the cap.
Make sure that the stylus is
clamped tightly and will not
drop.
CAUTION
(1) If the stylus is inserted
improperly, digitizing oper-
ation cannot be made properlyw
Be sure to insert the atylus
to the extreme end (or until
it is pushed into the pen).
If the stylus is pushed in
too strongly, the pen may be
broken.
(2) Do not pull on the cable, nor
bend the cable end.
(3) Do not tap an object with the
stylus pen •

3. I/O ports
3.1 RS-232C ports (serial port)
Two bi-directional half-duplex RS-232C ports are available.
Pins are arranged so that Port A is configured as a modem,
and Port B as a terminal. The difference between the
modem and terminal configurations is that all lines on the
same pin number have reversed roles as regards input/output,
or, e.g., Pin No. 2 (Transmit Data) of Port A (modem) is for
data input while the same number pins of Port B (terminal)
is for data output. Table 3.1 shows the pin assignments.
Connectors
AMP206584-l and DB-25P (cable side)
Before plugging in the connector, determine whether it is
to be connected to Port A or B taking into account the
following items.
{l) Type of external device port (modem configuration or
terminal configuration)
(2) Type of connecting cable (direct type for modem-to-
terminal connection or cross type for terminal-to-
terminal connection)
For example, if the cross type cable is used for connect-
ing a CRT display to the HDG-1111, the cable connector
should be plugged into the Port B.

Single port operation mode
Data output/command input can be made through selected one
of the RS-232C ports. Any data input through the other
port will be ignored. Meaningless data or invalid commands
input to the selected port are also ignored.

Dual port operation mode
Both the RS-232C Ports A and B are effective in this mode.
Either of these ports selected by the PORTA/PORT B selector
switch (Port A when DSW2-2 is ON, Port B when DSW-2-2 is
OFF) or main Port selection command is called main port,
and the other is subport.
XY coordinate data is transmitted from the both ports if the
subport is enabled by turning OFF the DSW2-l, and is output
only from the main port if the subpart is disabled. Commands
are input to the HDG-1111 only from the main port.
Data transfer between PORT A-PORT B is a unique feature of
the dual port operation mode. All data input to the subport
will be transferred to the main port before being transmit-
ted.
Among the data sent to the main port, those other than
command data are transferred to the subpart before being
transmitted. The command data are 02 HEX for stop-data-
output, 04 HEX for resume-data-output, and 01 HEX followed
by two ASCII characters.
The data transfer between the input and output will results
in a delay of approximately 0.1 ms.
