Notice to Users
Z-WORLD PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL
COMPONENTS IN LIFE-SUPPORT DEVICES OR SYSTEMS UNLESS A SPE-
CIFIC WRITTEN AGREEMENT REGARDING SUCH INTENDED USE IS EN-
TERED INTO BETWEEN THE CUSTOMER AND Z-WORLD PRIOR TO USE.
Life-support devices or systems are devices or systems intended for surgical im-
plantation into the body or to sustain life, and whose failure to perform, when
properly used in accordance with instructions for use provided in the labeling and
users manual, can be reasonably expected to result in significant injury.
No complex software or hardware system is perfect. Bugs are always present in a
system of any size. In order to prevent danger to life or property, it is the responsi-
bility of the system designer to incorporate redundant protective mechanisms ap-
propriate to the risk involved.
All Z-World products are 100 percent functionally tested. Additional testing may
include visual quality control inspections or mechanical defects analyzer inspections.
Specifications are based on characterization of tested sample units rather than testing
over temperature and voltage of each unit. Z-World may qualify components to operate
within a range of parameters that is different from the manufacturers recommended
range. This strategy is believed to be more economical and effective. Additional
testing or burn-in of an individual unit is available by special arrangement.

OP7100 Overview s11
CHAPTER 1: OVERVIEW
Chapter 1 provides an overview and a brief description of the OP7100
features.

OP710012 sOverview
Introduction
The OP7100 is a serial graphic display in a compact, easy to integrate
module. The OP7100 features an LCD that has a white background with
blue images. The LCD has pixel graphics and provides two-color (mono-
chrome) displays. Five standard fonts are included in the supplied soft-
ware. Additional custom fonts are easily created to meet the needs of an
application.
The OP7100 can operate with Z-World single-board computers or other
serial displays over an RS-485 network. The OP7100 also supports
RS-232 communication.
The OP7100 display terminal uses display technologies that require mini-
mal mounting depth and offer maximum viewing angles. The memory
allows up to 25 application-screen bitmaps (240 × 320) to be stored with-
out compression in a 256K flash EPROM. A further 256K is available for
the application in a second flash EPROM.
Figure 1-1 illustrates the standard OP7100 board layout.

Development and Evaluation Tools
The OP7100 is supported by a Tool Kit that include everything you need
to start development with the OP7100.
The Tool Kit includes these items.
 Serial cable
 24 V DC power supply capable of delivering 1.1 A
 Users manual with schematics
An optional Serial Interface Board (SIB) is available to program the
OP7100 when a second RS-232 serial port is needed by the application
being developed.
For ordering information, call your Z-World Sales Representa-
tive at [phone].
Software
The OP7100 is programmed using Z-Worlds Dynamic C, an integrated
development environment that includes an editor, a C compiler, and a
debugger. Library functions provide an easy and robust interface to the
OP7100.
Z-Worlds Dynamic C reference manuals provide complete
software descriptions and programming instructions.
$

OP7100 Overview s15
CE Compliance
The OP7100 has been tested and was found to be in
conformity with applicable EN immunity and emission
standards. Note the following requirements for incorporat-
ing the OP7100 into your application to comply with CE
requirements.
The power supply provided with the Tool Kit is for development
purpose only. It is the customers responsibility to provide a CE
compliant power supply for their end-product application.
The OP7100 has been tested to meet the following immunity standards.
EN61000-4-2 (ESD)
EN61000-4-3 (Radiated Immunity)
EN61000-4-4 (EFT)
EN61000-4-6 (Conducted Immunity)
Additional shielding or filtering may be required for a heavy industrial
environment.
The OP7100 has been tested to meet the EN55022 Class A emissions
standard with ferrite RFI suppressors on the I/O cables. Additional
shielding or filtering may be needed to meet Class B emissions
standards.
Since Z-World products are connected to other devices, good EMC prac-
tices should be taken to ensure compliance. CE compliance is eventually
the responsibility of the integrator. For more information on tips and
technical assistance, visit our Web site at www.zworld.com/products/
ce_certification/, or contact your local authorized Z-World distributor.

OP7100 Getting Started s17
CHAPTER 2: GETTING STARTED
Chapter 2 provides instructions for connecting the OP7100 to a host PC
and running a sample program.

OP710018 sGetting Started
Initial OP7100 Setup
Parts Required
 24 V unregulated DC power supply capable of delivering up to 1.1A
 Serial cable
The necessary parts are supplied with the Tool Kit.
Setting Up the OP7100
1. Remove the green power connector shown in Figure 2-1 from the back
of the OP7100.
2. Attach the bare leads from the power supply to the terminals on the
power connector as shown in Figure 2-1.
3. Plug the connector back into the power connection header at the back
of the OP7100. Watch the polarity of the connection so that the banded
wire from the power supply goes to DCIN as shown in Figure 2-1.
Figure 2-1. OP7100 Power Supply Connections
Be careful to connect the power supply wires to the correct
screw terminals on header J8. The OP7100 may be destroyed
if the power supply is connected to the wrong screw terminal.
A protective diode prevents damage to the OP7100 if the
power supply polarity is reversed.
4. Plug the power supply into a wall outlet. The display should now light up
with the demonstration screens shown in Figure 2-2.

S/N:
Connecting the OP7100 to a Host PC
1. Unplug any power supply connected to the OP7100 and remove the
back cover from the OP7100 assembly. The back cover is attached
with the two screws shown in Figure 2-3.
Figure 2-3. OP7100 Back Cover
2. Establish a serial communication link. A PC communicates with the
OP7100 via Serial Port 0 or the Clocked Serial Input/Output port on
the OP7100s Z180 microprocessor. There are two options for the
serial communication link.
Option 1 (via optional SIB)Connect an RJ-12 cable between the PC
and the SIB. An RJ-12 to DE-9 adapter is included for DE-9 PC COM
ports. Remove any jumpers that may be installed on the OP7100s
header J4 and plug the SIBs 8-pin connector onto header J4 as shown
in Figure2-4. Make sure that pin 1 on the ribbon cable connector (on
the striped side) matches up with pin 1 on J4 (indicated by a small
white circle next to the header).
Option 2 (directly)Place a jumper across pins 12 of header J4 on the
OP7100 as shown in Figure 2-5. Connect the PC COM port to the DE-9
jack on the OP7100, header J7, using the DE-9 to DE-9 cable supplied
with the Tool Kit.
3. The OP7100 is now ready for programming. The power supply may be
plugged in and turned on.
