Note: The interface does not have apower switch. The power is

switched together with the power switch of the connected
computer. Disconnecting the computer turns off the power
for the interface.

Connects the computer (PC-1600).

® Printer connector

Connects a printer through the printer cable (EA-158C).

® Pocket disk drive connector

Connects the pocket disk drive (CE-1600F)

@

Adaptor plug
Connects the AC adaptor (EA-160)

4. POWER SUPPLY

Size AA batleries (or an adaptor) are required in the interface to
operate the disk drive.

When the

I

BAIT

I

symbol is shown on the top right of the computer's
display, the batlery vohage is low. Replace the batleries in the
interface early.

Note: The interface and computer both supply power alternately.

Thus, operation is possible if power is available from either
one. However, the disk drive's motoroperates from the power
supplied by the interface.

5. ERROR CODES

The interface issues error code 69 during an error.

ErrorCode

Description

Printer is not connected. Printer is not on. Printer

69

is out of paper. Other printer related error
conditions.

SHARP CORPORATION

•

CE-1600E

If the printer takes 10 seconds or more lor the new page operation,

an error occurs when an attempt is made to output data following
the new page code (LPRINT CHR$(12);). I1 an error occurs, add
the following command.
1 ON ERROR GOTO 60000

60000 IF ERN=69 THEN RESUME
Lines 1 and 60000 are repeated until the new page operation is

completed.

6. END OF LlNE CODES AND
PROGRAM LlSTING FORMATS

Output of the end of line code at the end of a line can be turned
on and off if the amount of data exceeds the number of columns
per line specified in the PCONSOLE statement. Also, when
outputling a program listing, printing of the 2nd and subsequent
lines can be started from the first column or the 8th column.

End of Llne Code Output

Problems may arise if the number of print columns per line set in
the PCONSOLE statement is not the same as the number of printable
columns for the printer. Furthermore, most printers automatically
perform a line feed after receiving an entire line of printable

characters.
(1) Select "do not output end 01line code" Irom below il the value

132 is set in the PCONSOLE statement and the number of

printable columns for the printer is 80.

If "output end of line code" is selected, the printer will
automatically perform a line feed after the 80th column and
again after the 132nd column.

(2) Select "output end of line code" from below if the value80is

set in the PCONSOLE statement and the number 01 printable
columns for the printer is 132.

I1"do not output end of line code" is selected, the 81st column
will be output on the same line. Furthermore, if "print from the

8th column" has been selected, 7 spaces will be inserted

between the 80th and 81st columns.

Selectlon of the Start Prlntlng Position

Since the line number is printed from the first column, long program

lines that require 2 or more printed lines can be printed with 2nd
and subsequent printed lines starting from the 8th column to make
the overall program listing easier to read. Select this indentation
leature for easier to red program listings.

When the PC-1600 is connected to interface for the first time or
when the raset button is pressed, X=0 will be selected. Futhermore,
whenever the power is tumed on again, the previous values that
were specified belore the power was tumed off are retained.

Note: The end of line code referred to on the previous page is

specified in the PCONSOLE statement. However, if a program
line is less that the number of columns per line specified in
the PCONSOLE statement, the end of line code specified in

the PCONSOLE statement will be output.

PRINTER INTERFACE

The interface can connect with most Centronics compatible printers.
The interface uses handshaking through the BUSY siqnal. For your
reference, the printer interface connector signals, printer cable
wiring, signal timing chart, and electrical

requtrements

are given in
the following. The information is not necessary il a SHARP
recommended printer and cable are used.

state. See the operaation manual for your printer. Also some printers
provide a switch for the SELECT state.

14. Character Codes

Some characters that are displayed on the PC-1600 maybedifferent from
those printed on the printer. Furthermore, codes &00-&1F are usually
control codes on most printers and will differ from the displayed charac-
ters. See the operation manual lor your printer. The character lonts may
also differ depending on your printer.

Mode 0 Character Code Table

In Mode 0, the PC-1600 character set includes graphic and Greek symbols
and internationa' onaracters in addition to the normal upper and lower
case leiters, numbers and symbols. This character set is similar to the
IBM PC character set.
