1. INTRODUCTION
The LP3500 is a low-power single-board computer with built-in
analog and digital I/O. Although the LP3500 was designed spe-
cifically for low-power applications and data logging, it has a
host of features that make it attractive for other applications as
well. Low power is often required in portable equipment operat-
ing from batteries or from solar power. The LP3500 is ideal for
monitoring equipment or processes that are far-removed from a
power supply, remote telemetry (RTUs), pipeline control and
monitoring, well-head monitoring; and use on mobile equipment
such as refrigeration trucks. An optional plastic enclosure and an
LCD/keypad module are available.
The Tool Kit has the essentials that you need to design your own
low-power microprocessor-based system, and includes a com-
plete Dynamic C software development system.
1.1 LP3500 Description
The LP3500 is a low-power single-board computer that incorporates the powerful and
low-EMI Rabbit 3000 microprocessor, flash memory, static RAM, digital I/O ports, A/D
converter inputs, PWM outputs, RS-232/RS-485 serial ports, and both parallel and serial
interfaces that allow other devices to be connected to the LP3500.
All aspects of the LP3500 are designed for low power consumption and operates at a vari-
ety of power levels, including a power-save mode, to fit customer-specified conditions at
any given time. The CPU runs at a nominal speed of 7.4 MHz, and operates at 2.8 V to
conserve power. The LP3500 consumes less than 20 mA when fully operational, and less
than 100 µA when in the power-save mode. A replaceable coin-type battery will allow the
LP3500 to operate in sleep mode for over 3 years. The LP3500 is normally powered from
an external battery or power supply. When the unit is in the power-save mode, it can be
awakened by an internal timer, an RS-232 signal, or via polling of an external input. The
LP3500 can be switched from the power-save mode to full operation and back under pro-
gram control. In addition, various sections of circuitry (such as the RS-232 ports) can be
switched off under program control to further conserve power when not in use.

1 asynchronous clocked serial port dedicated for programming
•Battery-backed real-time clock.
•Watchdog supervisor.
Two LP3500 models are available. Their standard features are summarized in Table 1.
Appendix A provides detailed specifications.
The LP3500 can be mounted in two ways. It can be mounted to a panel or on a plastic-
enclosure base, which allows I/O connections to be made using traditional connectors with
0.1" spacing. The LP3500 can also be inverted and mounted directly to mating connectors
on a motherboard of the customer's design. The first approach is appropriate where I/O
connections go directly to devices and switches. The second approach is appropriate
where additional circuitry is incorporated on the motherboard.

1.5 CE Compliance
Equipment is generally divided into two classes.
These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequencies
above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbit-based
systems at frequencies above 300 MHz are generally well below background noise levels.
The LP3500 has been tested and was found to be in conformity with the
following applicable immunity and emission standards. The LP3510 is
also CE qualified as it is a sub-version of the LP3500. Boards that are
CE-compliant have the CE mark.
NOTE: Earlier versions of the LP3500 sold before 2003 that do not
have the CE mark are not CE-complaint.
Immunity
The LP3500 series of single-board computers meets the following EN55024/1998 immu-
nity standards.
•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.
Emissions
The LP3500 series of single-board computers meets the following emission standards
emission standards with the Rabbit 3000 spectrum spreader turned on and set to the nor-
mal mode.
•EN55022:1998 Class B
•FCC Part 15 Class B
Your results may vary, depending on your application, so additional shielding or filtering
may be needed to maintain the Class B emission qualification.
CLASS A CLASS B
Digital equipment meant for light industrial use Digital equipment meant for home use
Less restrictive emissions requirement:
less than 40 dB µV/m at 10 m
(40 dB relative to 1 µV/m) or 300 µV/m
More restrictive emissions requirement:
30 dB µV/m at 10 m or 100 µV/m

User’s Manual 7
1.5.1 Design Guidelines
Note the following requirements for incorporating the LP3500 series of single-board
computers into your application to comply with CE requirements.
General
•The power supply provided with the Tool Kit is for development purposes only. It is the
customer’s responsibility to provide a CE-compliant power supply for the end-product
application.
•When connecting the LP3500 to outdoor cables, the customer is responsible for provid-
ing CE-approved surge/lightning protection.
•Z-World recommends placing digital I/O or analog cables that are 3 m or longer in a
metal conduit to assist in maintaining CE compliance and to conform to good cable
design practices. Z-World also recommends using properly shielded I/O cables in noisy
electromagnetic environments.
Safety
•For personal safety, all inputs and outputs to and from the LP3500 must not be con-
nected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC). Damage to
the Rabbit 3000 microprocessor may result if voltages outside the design range of 0 V
to 40 V DC are applied directly to any of its digital inputs.
•The lithium backup battery circuit on the LP3500 has been designed to protect the bat-
tery from hazardous conditions such as reverse charging and excessive current flows.
Do not disable the safety features of the design.
1.5.2 Interfacing the LP3500 to Other Devices
There are two versions of the LCD/keypad module that may be used with the LP3500:
without a bezel (Z-World part number 101-0601), and a remote panel-mounted version
with bezel (Z-World part number 101-0541). The cable used to connect the LCD/keypad
module should be less than 30 cm (12") to maintain CE compliance. Appendix C provides
complete information for mounting and using the LCD/keypad module.
Since the LP3500 series of single-board computers is designed to be connected to other
devices, good EMC practices should be followed to ensure compliance. CE compliance is
ultimately the responsibility of the integrator. Additional information, tips, and technical
assistance are available from your authorized Z-World distributor, and are also available
on our Web site at www.zworld.com.

4. Connect the programming cable to download programs from your PC and to program
and debug the LP3500.
NOTE: Use only the programming cable that has a red shrink wrap around the RS-232
level converter (Z-World part number 101-0276), which is supplied with the LP3500
Tool Kit. Other Z-World programming cables might not be voltage-compatible or their
connector sizes may be different.
Connect the 10-pin PROG connector of the programming cable to header J5 on the LP3500
board. Ensure that the colored edge lines up with pin 1 as shown. There is a small dot on the
circuit board next to pin 1 of header J5. (Do not use the DIAG connector, which is used for
monitoring only, as explained in Appendix F, “Programming Cable.”) Connect the other
end of the programming cable to a COM port on your PC. Make a note of the port to
which you connect the cable, as Dynamic C will need to have this parameter configured.
Note that COM1 on the PC is the default COM port used by Dynamic C.

5. Connect the power supply.
Hook up the connector from the wall transformer to header J5 on the Prototyping Board as
shown in Figure 4. The orientation of this connector is not important since the VIN (posi-
tive) voltage is the middle pin, and GND is available on both ends of the three-pin header
J5.
NOTE: Do not connect the AC adapter to the VBAT terminal on the Prototyping Board.
The VBAT terminal supplies the backup battery voltage of 3 V, and the LP3500 may be
damaged if subjected to the raw DC voltage from the AC adapter through the VBAT
terminal.
6. Apply power.
Plug in the AC adapter. If you are using your own power supply, it must provide 3 V to
30 V DC—voltages outside this range could damage the LP3500.
NOTE: A hardware reset may be done by pressing the RESET switch on the LP3500.
The LP3500 may also be reset by unplugging the AC adapter, then plugging it back in.
However, when the LP3500 is operating in the power-save mode, the backup battery
will provide sufficient voltage to prevent a reset from happening, in which case you will
have to press the RESET switch on the LP3500.
Figure 5. Locations of LP3500 RESET Switches
Reset switches are located on both sides of the LP3500 board.

2.2 Remove Battery Tab
The backup battery on the LP3500 has a plastic tab to protect the battery against discharg-
ing before the LP3500 is placed into service.
Figure 6. Remove Battery Tab
NOTE: Z-World recommends that the battery tab not be removed until you are ready to
place the LP3500 in normal service with regular power connected to header J3.
The backup battery protects the contents of the SRAM and keeps the real-time clock
running when regular power to the LP3500 is interrupted. If you plan to use the real-time
clock functionality in your application, you will need to set the real-time clock once you
remove the plastic tab. Set the real-time clock using the onscreen prompts in the demon-
stration program. Alternatively, you may set the real-time clock using the SETRTCKB.C
sample program from the Dynamic C SAMPLES\RTCLOCK folder. The RTC_TEST.C
sample program in the Dynamic C SAMPLES\RTCLOCK folder provides additional exam-
ples of how to read and set the real-time clock.

2.3 Installing Dynamic C
If you have not yet installed Dynamic C version 7.26P (or a later version), do so now by
inserting the Dynamic C CD in your PC’s CD-ROM drive. The CD will auto-install unless
you have disabled auto-install on your PC.
If the CD does not auto-install, click Start > Run from the Windows Start button and
browse for the Dynamic C setup.exe file on your CD drive. Click OK to begin the
installation once you have selected the setup.exe file.
The Dynamic C User’s Manual provides detailed instructions for the installation of
Dynamic C and any future upgrades.
NOTE: If you have an earlier version of Dynamic C already installed, the default instal-
lation of the later version will be in a different folder, and a separate icon will appear on
your desktop.
2.4 Starting Dynamic C
Once the LP3500 is connected to your PC and to a power source, start Dynamic C by dou-
ble-clicking on the Dynamic C icon or by double-clicking on the .exe file associated
with DcRab in the Dynamic C directory.
Dynamic C assumes, by default, that you are using serial port COM1 on your PC. If you
are
using COM1, then Dynamic C should detect the LP3500 and go through a sequence of
steps to cold-boot the LP3500 and to compile the BIOS. If the error message “Rabbit Pro-
cessor Not Detected” appears, you have probably connected to a different PC serial port
such as COM2, COM3, or COM4. You can change the serial port used by Dynamic C with
the OPTIONS menu, then try to get Dynamic C to recognize the LP3500 by selecting
Reset Target/Compile BIOS on the Compile menu. Try the different COM ports in the
OPTIONS menu until you find the one you are connected to. If you still can’t get Dynamic
C to recognize the target on any port, then the hookup may be wrong or the COM port
might not working on your PC.
Dynamic C automatically uses a maximum debug baud rate of 38,400 bps when an
LP3500 series board is in use.
