1.0 SmaRT 218, 918 Remote Control System
✓ Note: The operating frequency for a SmaRT system will be either in the 900 MHz or 2.4 GHz
range. The first number in the system or device name indicates the operating frequency. For
instance, a SmaRT 18-button handheld remote with an ON button and an OFF button will
either be OO-218 or OO-918, where “2”indicates 2.4 GHz and “9”indicates 900 MHz. As
such, references to the system, handheld remote, and base unit in this manual will use “x”in
the name (rather than “2”or “9”) to indicate the operating frequency.
A standard SmaRT x18 Remote Control System consists of a SmaRT OO-x18 18-button
handheld remote control unit and a BU-x16F base unit. A SmaRT system can communicate in
congested radio environments using Direct Sequence Spread Spectrum (DSSS) wireless
technology at a system-dependent 900 MHz or 2.4 GHz range. The system communication link
between the handheld remote control and the base unit is established at the factory using a
process known as “Association.”The system can also be seamlessly associated in the field—
without the need to open the enclosures of either unit—by a wireless process described later in
this manual.
The OO-x18 handheld remote has a dedicated ON button and an OFF button. The remaining
sixteen buttons are assigned to and used to control the base unit outputs. The BU-x16F base
unit has sixteen solid state field effect transistor (FET) channels. System configuration is
extended as the input/output (I/O) can also be custom-configured by Cervis Engineering to be
inputs or outputs.

mobile applications capable of activating and deactivating SmaRT base unit input/outputs. The
handheld remote permits single-handed operation in a comfortable, ergonomic layout.
Using direct sequence spread spectrum (DSSS) wireless technology at the 900 MHz or 2.4 GHz
(system-dependent) range to communicate, the SmaRT 18-button handheld remote creates a
robust link with a base unit in congested radio environments. The handheld remote allows
seamless association to a SmaRT base unit without the need to open either unit’s case. The
rugged weatherproof handheld enclosure allows the unit to operate worry free in harsh weather
conditions.

2.2 SmaRT x18 Handheld Battery Installation
The handheld remote operates between 1.6 to 3.2 VDC powered by four factory installed 1.5 V
“AA”cell batteries. Cervis, Inc. recommends having fresh spare batteries on hand at all times
that the system is in use.
 Note: The battery cover is designed so that the four screws holding the battery cover in
place are “captive”to the cover. Although not easily removed from the cover itself, be aware
that if the screws are over-loosened while opening the battery compartment, they can be
completely removed, increasing the risk of loss. All four screws must be installed to maintain
a tight seal.
1. Place the remote face down, and remove the four screws holding the battery
cover in place. Remove the battery cover.
2. Remove the discharged batteries and properly dispose according to local
regulations.
3. Plug each fresh battery into a terminal cradle observing proper polarity. The
interior of the cradle shows polarity markings for each terminal (Figure 3). Make
sure the batteries are firmly seated in the cradle.
4. Replace the battery cover. Secure the cover with the four screws. Make sure
they are tightened enough to compress the seal, but be careful not to over-
tighten.
Figure 3. OO-218 Handheld Battery Compartment
Observe proper polarity when placing batteries into the cradle.
Improper battery placement can cause excessive heat, battery
explosion, injury to the operator, and damage to the remote.
✓ Note: Cervis, Inc. recommends removing the batteries from the handheld remote when it is
going to be stored for any extended length of time.

4.0 Associate Mode
Use the Associate Mode to establish the communications
link between the 18-button handheld remote and base unit
on a 1-to-1 basis. There must be a clear line of sight
between the handheld and the base unit to associate, and
both units must be OFF (powered down). Turn off the 18-
Button Handheld by pressing the OFF button. Safely
power down the SmaRT base unit by removing the power
source from the unit.
To prevent inadvertent machine
movement, be sure to remove
power from the base unit before
attempting to enter Associate
Mode.
Observe LED states while performing the following
Association:
1. Remove power from the base unit, and make sure
the handheld turned off.
2. Stand near the base unit’s antenna (if the base unit has an internal antenna,
stand near the base unit) with the handheld in clear line-of-sight.
3. Press and hold button 12, then press and hold the ON button. After
approximately three seconds, LEDs 1 (Green) and 3 (Red) light solid.
4. Continue to hold both buttons until LED 2 (Amber) goes out. Immediately release
both buttons, and press Button 1 (the button between the ON and OFF buttons).
5. Continue holding Button 1. Apply power to the base unit. Association is
successful when LED 2 (Amber) begins to flash and LED 3 (Red) goes out.
6. Release Button 1. You can now begin to normally operate the system.
 Note: If LED 1 (Green) and LED 2 (Amber) are flashing together yet no outputs are
responding to button presses, turn the handheld off and then remove and reapply power to
the base unit. Control should be reestablished when the handheld is turned back on.
✓ Note: The label on early versions of the OO-x18 handheld remote indicated eight LED
places numbered left-to-right as 1 through 8, respectively, as opposed to the current six LED
places shown throughout this manual, which are numbered from left-to-right as 1 though 6.
LED numbers 2 (green), 3 (amber), and 4 (red) were the active LEDs on the eight-place
units, which respectively relate to active LED numbers 1 (green), 2 (amber), and 3 (red) in the
current version shown in this manual.

“Momentary”means that the output(s) under control should only change
state (going from inactive to active or active to inactive) when the
appropriate handheld button or switch is positioned, and then only for the
duration of time that particular control remains positioned. Investigate any
unexpected or unintended motion that occurs when manipulating the
handheld unit's controls, or when no handheld controls are being
manipulated.
Immediately stop operating if a jerky motion occurswhile manipulating the
handheld’s controls. Check the handheld and base unit diagnostic LEDs for
any indication of a problem. The particular SmaRT base unit manual
contains diagnostic descriptions.
Be aware that even if the handheld and base unit diagnostic LEDs do not
indicate a problem, one may be present, and further troubleshooting steps
may be needed.
If a problem is found, do not operate the SmaRT System until the problem
is resolved.
