COMPUTER AND PRINTER INTERFACE

General Information

The CLINITEK ® 500 Urine Chemistry Analyzer can be
interfaced to a host computer or LIS (Laboratory Infor-
mation System) via the serial port on the instrument
(labeled " "). It can also be interfaced to an 80-column
or form printer through the parallel (Centronics) port
(labeled " "). This appendix contains the specifications
for the interface cables needed to accomplish these inter-
faces. Additional information needed to write a program
to interface the CLINITEK 500 Analyzer with a computer
can be obtained from your nearest Bayer Customer Service
Department or office.
Cable and Pin Specifications — Serial Port
The cable normally used to interface with the CLINITEK
500 instrument is a Null modem cable. This cable cross-
es pins 2 and 3, 4 and 5, and 6 and 20; pins 1 and 7 are
straight through. Refer to Table CPI-1 for definitions of
the pin assignments and hardware handshaking.
Cable and Pin Specifications — Parallel
Port
The printer (parallel data) port is of the "Centronics"
style of interface with a DB-25 connector and is provided
for use with either of two types of printers:
1. Any standard 80-column printer having a Centronics
style of interface — the External Printer option must
be set to "ON, 80 Column" in the Setup Routine
(Section 3, Step A-4a-iii). The interface cable that
is used to connect the 80-column printer to the
CLINITEK 500 instrument must contain a DB-25 male
connector (standard IBM configuration). Refer to
Table CPI-2 for definitions of the pin assignments.
Revised 5/01
2. Form Printers — three special formats of data are gen-
erated for use with various form printers when the
External Printer option is set to "ON, Form Printer 1,"
"ON, Form Printer 2," or "ON, Form Printer 3" in the
Setup Routine (Section 3, Step A-4a-iii).
2. • Form Printer 1 creates a format that is appropriate
for use with the Printer Products Form Printer. It
adds 9 spaces to the beginning of each line so the
results align in the proper location on the CLINITEK
Report Form. The display includes a "Reprint" key
that can be used if a record needs to be reprinted.
2. • Form Printer 2 is appropriate for use with the
CLINITEK ® Form Printer. The results are transmitted
without any additional spaces in front of each line.
Records are reprinted using the "Reprint" key on the
Form Printer.
2. • Form Printer 3 can be used with the Star Form
Printer (Bayer Product No. 5257) and other simple
form printers. This format includes a command to
the printer that prevents it from printing a record
until a form is in place. It also includes a command
to eject the form out of the front of the printer. The
CLINITEK 500 display includes a "Reprint" key
that can be used if a record needs to be reprinted.
Extra spaces are not transmitted with this format.
2. If you are unsure of which format to use, print a record
using each of the Form Printer options to determine
which one provides the best placement of the printed
results on the form and works appropriately with your
form printer.
