1.0 SmaRT DO-x18 18-Button Handheld Remote Control
 Note: Frequency of operation for a SmaRT handheld remote will be in the 900MHz
or 2.4GHz range. The first number in the name of the system or device indicates the
frequency of operation. For instance, a SmaRT 18-button handheld remote with a
single button serving as the ON and OFF button will either be DO-218 or DO-918,
where a 2 indicates 2.4GHz and 9 indicates 900MHz. As such, reference to the,
handheld remote, base unit, or system in this manual will use x rather than a 2 or 9
in the name to indicate the frequency of operation.
The SmaRT DO-x18 18-Button Handheld Remote is designed for traditional and non-
traditional mobile applications capable of activating and deactivating the input/outputs of
SmaRT base units. The ergonomic layout of the handheld remote provides for
comfortable remote operation of the SmaRT system.
Using direct sequence spread spectrum (DSSS) wireless technology at the 900MHz or
2.4GHz (system dependant) range to communicate, the SmaRT DO-x18 eighteen
button handheld remote provides 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 the case of either unit. The rugged weatherproof handheld
enclosure allows the unit to operate worry free in harsh weather conditions.

1.2 SmaRT DO-x18 Remote Control System
A standard SmaRT DO-x18 Remote Control System consists of a SmaRT DO-x18
eighteen button handheld remote control unit and a BU-x16F base unit. A SmaRT
system is capable of communicating in congested radio environments using Direct
Sequence Spread Spectrum (DSSS) wireless technology at a system dependant
900MHz or 2.4GHz 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 DO-x18 handheld remote has a single button with which the unit is switched ON
and OFF. The remaining seventeen buttons are assigned and used to control the
sixteen base unit outputs, or custom programmed to serve a special function. Custom
program options are available through the Cervis Engineering Department.
Figure 2. Standard SmaRT DO-x18 System
The BU-x16F base unit has sixteen solid state FET channels. System configuration is
extended as the I/O can also be custom configured by the Cervis Engineering
Department to be inputs or outputs.

1.3 SmaRT DO-x18 Handheld Battery Installation
The handheld remote operates between 1.6 to 3.2VDC powered by four factory
installed 1.5V AA alkaline batteries. Cervis, Inc. recommends that fresh spare batteries
be at 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 in accordance with 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. 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. DO-x18 Handheld Battery Compartment
Observe proper polarity when placing batteries into the cradle. Improper
battery placement can result in excessive heat, battery explosion, injury
to the operator, and damage to the remote.
 Note: Cervis, Inc. recommends that the batteries be removed from the handheld
remote when the remote is going to be stored for any extended length of time.

1.4 Low Battery Warning
When low voltage is sensed—approximately 1.7V—the AMBER RX LED will no longer
indicate that there is an incoming message. Instead, the LED will begin to flash
approximately once per second indicating a Low Battery Warning. Messages are still
being received, and the handheld can still be used, but it is recommended that a fresh
set of four AA batteries should be installed as soon as possible.
Figure 4. Low Battery Warning and Auto-Shutdown
1.5 Low Battery Auto-Shutdown
When the critical Auto-Shutdown voltage is sensed (approximately 1.6VDC), the
AMBER RX LED will stop pulsing, the handheld will no longer communicate with the
base unit, the RED LED will pulse for approximately 30 seconds indicating the handheld
remote is about to completely shut down. The four AA batteries must be replaced
before the handheld remote can be used.
LOW BATTERY WARNING
At Low Voltage, the AMBER RX LED stops flashing as messages are received by the
handheld remote from the base unit. Messages are still being received, but they are not
indicated by the LED. The RX LED begins flashing once per second indicating a LOW
BATTERY situation is present. The batteries should be replaced with four fresh AA batteries
as soon as possible. The LED will continue to flash at one second intervals until the batteries
are changed, or until the voltage level drops to the level where Auto-Shutdown occurs.
LOW BATTERY AUTO-SHUTDOWN
As the critical Auto-Shutdown voltage is sensed, the AMBER LED stops flashing.
The RED LED flashes for approximately 30 seconds indicating the handheld remote
is automatically shutting down. The four AA batteries must be replaced before the
handheld can be used again.

3.0 Associate Mode
The Associate Mode is used to establish the
communications link between the 18-button handheld
remote and base unit on a 1-to-1 basis. Both units must be
OFF (powered down), and the handheld must be close to
the base unit with a clear line of sight between handheld
and base to associate. The SmaRT base unit is safely
powered down by disconnecting P1 and P2 or by removing
the power source from the unit.
To prevent inadvertent movement of the
machine, be sure to remove power from
the Base Unit before attempting to enter
the Associate Mode.
Observe LED states while performing the following
Association:
1. Remove power from the base unit by disconnecting P1
and P2 and turn off the handheld.
2. Stand near the base unit with the handheld in clear line-of-sight.
3. Press and hold button 13 and then press and hold the ON/OFF button. LEDs #1
(green), #2 (amber), and #3 (red) light solid.
4. Continue to hold both buttons until the Amber LED (#2)goes OUT. Immediately
release both the ON and 13 buttons. You have approximately 2 seconds to perform
the next step. If you miss this window of opportunity, you must restart this procedure
starting at Step 3.
5. Press and hold button 1. Wait until Amber LED #2 goes out.
6. Turn the base unit ON while holding button 1. LEDs illuminate..
7. When the Red LED #3 goes out, release button 1.
If the Association is successful, green LED #1 and amber LED #2 will continually flash
(TX and RX respectively) indicating that the handheld and the base unit are
communicating.
 Note: The label on early versions of the DO-x18 handheld remote indicated eight
LED places numbered left-to-right as 1 though 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.

Push-To-Operate means that the outputs under control should only change
states when the appropriate button or switch of the handheld is pressed or
positioned, and then only for the duration of time that particular output button
is pressed. Any unexpected motion that occurs when pressing the output
control buttons of the handheld must be investigated.
Should a jerkiness of motion occur while constantly pressing an output
switch, immediately stop operation. Check the base unit diagnostic LEDs for
any indication of a problem. Diagnostic descriptions are found in the manual
of the particular SmaRT base unit being used.
Be aware that even if the 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.
