Read Me First!
Your new Maple Systems OIT comes from the factory without any
communications protocol or operational software installed; therefore
•The OIT will NOT operate until it has been configured using
OITware-200 or STEPware-100.
•When power is first applied, the OIT’s display will indicate that it
needs to be configured.
•Use the OITware-200 or STEPware-100 software to create a file
(or “project”) that can be downloaded to the OIT.
•When the project is transferred, both communications protocol
and operational software are automatically loaded and the unit is
ready for operation.
To ensure that the OIT meets CE compliance, it is necessary to
follow all installation procedures described in this manual.

Introduction
Thank you for purchasing a Maple Systems OIT3200 or OIT3250. You have
selected a rugged, reliable, and powerful operator interface for your application.
This booklet describes the steps necessary to ensure trouble-free OIT system
operation. Please read this booklet carefully!!
Static Awareness
It is best NOT to remove the rear cover on the OIT except when replacing the
real-time clock battery on the OIT3250 (please refer to the “Battery Replacement”
section for more information). When the rear cover is removed, the circuitry inside
is exposed to possible damage by electrostatic discharge during handling.
Minimize the possibility of electrostatic discharge by:
•Discharging personal static by grounding yourself prior to handling the OIT.
•Handling the OIT at static-free, grounded work stations.
•Connecting the chassis of the OIT to a clean ground.
• Placing the OIT into an anti-static bag during transport.
Unpacking the Unit
Carefully unpack the OIT. Please read any instructions or cautions that appear on
the shipping container. Check all material in the container against the enclosed
packing list. Maple Systems, Inc., will not accept responsibility for shortages
against the packing list unless notified within 30 days. The equipment and its
accessories were inspected and tested by Maple Systems before shipment; all of the

1. Control Panel Design Guidelines
Pay careful attention to the placement of system components and associated cable
routing. These items can significantly enhance the performance and integrity of
your control application.
1.1. Control Panel Grounding
• The control panel should be connected to a good, high-integrity earth ground
both for safety considerations and shielding purposes. This must be a reliable
earth ground with a low-resistance path. The ideal earth ground would be a
copper grounding rod located close to the OIT and the control panel.
•Hinged doors on control panels do not provide a long term electrical connection
to the rest of the enclosure. Corrosion develops over time and prevents good
electrical contact. For this reason, a separate wire braid should be installed from
the hinged control panel to the rest of the enclosure.
1.2. Power Supply Selection
•The power supply used to power the OIT should have an output between +12
and +30 VDC. The voltage should measure between +12 and +30V at the OIT
between Pins 1 and 2 of the power connector. A 24 VDC, 0.5 amp linear power
supply dedicated to the OIT is recommended.
•The power cable for the OIT should be 18AWG 2-conductor wire with a shield
wire and protective shield foil. The shield of the OIT power cable must be
connected to earth ground at both ends of the cable. Please refer to the “Connect
OIT to Power” section and Appendix C for more information.

•A power line filter installed at the AC input to the OIT power supply is highly
recommended as a safeguard against conducted RF noise, which is often present
on factory power lines. The wires connecting the output of the power line filter
to the power supply should be kept as short as possible to minimize any
additional noise pickup. The case of the power line filter should be connected to
a quiet earth ground. The power line filter should have a current rating of at least
three amps with common mode and differential mode attenuation.
• The power supply that provides power to the OIT should not be used to power
switching relays or solenoids unless noise filter caps are connected to each relay.
1.3. OIT Cable Routing
• Always route the OIT communication cable and power cable away from any AC
voltage or PLC/host control wires.
• Never bundle the OIT cables together with 120 VAC power wires or with relay
wiring.
• Try to keep at least 8 inches (20 cm) of separation between the OIT cables and
other power wiring. If voltages greater than 120 VAC are used in the system,
greater separation is required.
•If the OIT cables must come near AC wiring, make sure they cross at 90 degrees.
•Running AC power wires in a separate grounded conduit is the preferred method
for electrical noise reduction.
•Keep the lengths of the OIT cables as short as possible. Do not coil excess cable
and place it next to AC powered equipment.
1.4. Other Steps to Improve Noise Immunity
•Always install the OIT’s rear cover. This provides a shield against electrical
noise which can be generated in the control panel by relays, motors, power lines,
and/or high frequency equipment. Ensure that all rear cover mounting screws
are properly secured.
•Any equipment used in the enclosure that operates at high frequency or high
current levels can be covered with a grounded metal shield.

2. OIT Installation
It is necessary to follow all installation procedures described in this chapter for
electrical noise immunity and CE compliance.
2.1. Set Jumper for Specific Protocol
This step is required for a few protocols only. Consult the Protocol Guides in your
documentation. If the protocol requires RS-485 half-duplex 3-wire
communication, proceed as follows:
STEPS
1. Remove the protective cover from the rear of the unit.
CAUTION: When the rear cover is removed, the circuitry inside is exposed to
possible damage by electrostatic discharge. Refer to Static Awareness on page 4.
2. Locate jumper “JP4” using Figure 3 as a guide. The jumper is installed on
the lower two pins of a 3-pin header. This is called Position “A”.
3. Move the jumper to the upper two pins of the 3-pin header (Position “B”).
Ensure that the jumper is pressed fully into place.
4. Replace the rear cover and the six retaining screws.
2.2. Prepare Panel for OIT Mounting
The OIT3200 and OIT3250 are mounted to a control panel from the front. For a
proper NEMA 4/12 seal, you will need a panel with a minimum thickness of
16-gauge (0.059 inches; 1.5 mm) steel or 10-gauge (0.102 inches; 2.6 mm)
aluminum. Thinner panels may bow between the mounting studs requiring the use
of a stiffener on the rear. Two gaskets on the inside rim of the OIT’s bezel provide
an environmental seal to NEMA 4/12.

2.4. Connect OIT Chassis Ground to Control Panel
The green ground wire assembly, supplied with the OIT, must be installed as shown.
This provides a good earth ground connection to the OIT’s bezel and rear cover.
If your control panel is metal, be sure it is grounded. If it is a non-conductive
material such as plastic, run an additional ground from either the dual-tab lug on the
OIT or the mounting stud (shown) to a good ground point. Use a braided grounding
strap that is as short as practical.
STEPS
1. Remove the mounting nut from the lower right hand stud, as viewed from the rear.
2. To install the green ground wire assembly, slip the #8 ring lug over the stud.

4. OIT3250 Special Features
4.1. Connecting to Printer
The second serial port of the OIT3250 is also used to connect to a serial printer.
This feature enables the OIT to print messages. The OIT 3250 uses XON/XOFF
software handshaking to communicate to the printer. The communications
parameters (ex. baud rate, parity, etc.) used are determined when the OIT is
configured. Consult the OITware-200 manual for more information. Connection
to the printer varies depending upon the pinout of the printer. See Figure 11 for the
OIT Port 2 pin assignments.

Figure 13 OIT3250 Bypass Mode Connection

The OIT3250 features a bypass mode which allows most PLC/host programming
software to communicate through the OIT to the PLC/host without having to
disconnect the cables from the OIT. Bypass mode does not work with PLC
programming software that uses hardware handshaking or 3-wire RS-485 connections.
To use bypass mode:
1. Plug the PC into Port 2 of the OIT.
2. Leave Port 1 connected to the PLC/host.
3. Press the Setup key on the OIT to enter the local setup mode.
4. Advance to the bypass mode setting to select the bypass operation.
5. Run the PLC/host program on the PC to communicate with the PLC/host.
6. When finished using bypass mode, the OIT must have power cycled in
order to operate in normal mode again.
NOTE: While the OIT operates in bypass mode, it cannot communicate with the
PLC/host. It is off-line.
4.3. Wiring for External Alarm/Keypress Buzzers
Outputs provided on Port 2 of the OIT3250 allow connections for external keypress
and alarm buzzers.
• The alarm buzzer output (Pin 8) can be used to turn on an external buzzer
whenever an alarm occurs on the OIT.
• The keypress buzzer output (Pin 9) can be used to turn on an external buzzer
whenever keys are pressed on the OIT. The external keypress buzzer mimics the
internal buzzer of the OIT. Therefore, when the internal buzzer is on, the
external keypress buzzer (if connected) will be on.
The outputs are open drain outputs which can sink DC current up to 200 mA. The
outputs can directly drive any buzzer with a maximum current draw of 200 mA. If
more current is required, a normally open relay is recommended as shown below.
NOTE: Ensure that the relay contacts are properly rated for the current required
to drive the selected alarm horn.

4.4. Battery Replacement
The OIT3250 is shipped with a 3V lithium coin cell battery installed for backing up
the real-time clock. During periods of power loss, the coin cell will allow the
internal clock to continue to run and keep accurate time. As long as power is
applied to the OIT, the battery will not be drained. The battery will experience no
loss of power until the OIT has been configured. Following OIT configuration, the
battery will last for approximately 4-6 months if the OIT is in a continually powered
down state. Replacement batteries can be Ray-O-Vac or Panasonic BR1225 or
equivalent 3V coin cell batteries.
STEPS
1. Remove the protective cover from the rear of the unit.
CAUTION: When the rear cover is removed, the circuitry inside is exposed to
possible damage by electrostatic discharge. Refer to Static Awareness on page 4.
2. Find the coin cell on the PCB. It looks like a 1/2-inch (12.7 mm) silver disk.
3. Insert a small screwdriver into the top of the socket near the positive
terminal and carefully twist the screwdriver to pop the cell loose.
4. Remove the cell from the socket and discard it.
5. Place the new coin cell into the socket at an angle, noting the polarity. The
positive side is indicated by a “+” on the cell (the widest side of the

5. Custom Keypad Slide-In Legends
The OIT3200 and OIT3250 have a graphic overlay covering the keypad. This
overlay contains clear windows that allow you to insert your own legends to
customize the text, color, and graphics of the twelve function keys and add your
own logo or model identification. Function keys F1, F2, F3, and F4 are on the left
legend; F5, F6, F7, and F8 are on the middle legend; and F9, F10, F11, and F12 are
on the right legend. The logo is on the logo legend. These legends can be
inexpensively made and are environmentally sealed when installed.
These slide-in legends can be made on any non-glossy stock between 0.004 inches
(0.1 mm) and 0.008 inches (0.2 mm) thick by either of the following methods:
•Photocopy the blank legends and hand illustrate.
•Use the dimensions to create computer generated legends.
5.1. Blank Legends for Photocopying
The blank legends in Figure 16 can be photocopied and hand illustrated.
When photocopying:
• Use only non-glossy stock which is 0.004 - 0.008 inches (0.1 - 0.2 mm) thick
• Check photocopy accuracy with the printed check dimension.
When illustrating:
• Use the tick marks to locate the window boundaries.
• Background colors should extend to the solid lines.
• All text and graphics should be 0.07 inches [1.78 mm] within the solid lines.
NOTE: Do not affix anything to the legend using glue, tape, stickers, etc.
