Foreword

Foreword

Thank you for purchasing the Topcon RC-2W Remote control system-2W.

For the best performance of the instrument, please read these brief instructions carefully, and

keep them in a convenient location for future reference.

This system has the following features:

●

Enables optical communications between the total station GTS-800A/810A/820A, GPT-8000A
and RC-2RW on the prism side, which allows simplified one-man survey based on the
application programs.

●

For communication between the RC-2RW on the prism side and the data collector FC-1000,
communication by either Bluetooth (wireless) or cable is possible.

●

Has the turn-round function with which more efficient one-man survey is possible.

General Handling Precautions

Before starting work or operation, be sure to check that this system is functioning correctly with
normal performance.

●

Do not submerge the instrument into water.

The instrument can not be submerged underwater.
RC-2RW is designed based on the International Standard IP65 and RC-2H is designed based on
the International Standard IP54, therefore it is protected from the normal rainfall.

●

Guarding the instrument against shocks.

When transporting the instrument, provide some protection to minimize the risk of shocks. Heavy
shocks may cause the measurement to be faulty.

●

Battery level check.

Confirm battery remaining level before operating.

●

Storing the instrument for long period

Remove the dry cells from the instrument when you would not use it for long period.

●

Tu r n-round motions and Optical communications
RC-2RW should be kept aiming so that the total station always stays within the above
range of laser beam emission until the turn-round motions or optical communications are
completed.
If the aiming is out of above range while RC-2RW is in turn-round motions or optical
communications, the turn-round or optical communications could not be completed.
See “Light emitting angle” on page 14 and “Light detecting range” on page 15.

Light emitting angle

Laser beams are emitted from the light emitter of the RC-2RW.
The angle of emitting laser beams is as follows.

Light emitting angle

At greater distances, the laser light at
the edge of the beam field (angle) will
be weaker.

Important

Light emitting angle

RC-2RW should be kept aiming so that the total station always stays within the
above range of laser beam emission until the turn-round motions or optical
communications are completed.
If the aiming is out of above range while RC-2RW is in turn-round motions or
optical communications, the turn-round or optical communications could not be
completed.

Light detecting range

The detecting angles of RC-2RW and RC-2H (Total station) are shown below:
Total station can only be turned round with the turn-round key under the condition that RC-2RW
remains confined within the range as shown below where RC-2H can detect light.
RC-2RW should be aimed in a way to always capture the total station within this range during
receiving data from the total station.

Turn-round function

RC-2RW should be kept aiming so that the total station always stays within the
above range of laser beam emission until the turn-round motions is completed.

Important

The turn-round key on RC-2RW is used to have the total station search or automatically track RC­2RW (prism).
In the auto tracking mode, RC-2RW and the total station are ready for optical communications.
Tu r n-round function is useful for auto-tracking when you start working or when the auto-tracking is
interrupted by any reason.
For increasing efficiency, keep the auto-tracking status when you move to another measurement
point.

Note

Tu rn on the total station and execute the [External Link].

Aim the RC-2RW light emitter at the total station.

2

If the aiming is out of above range while RC-2RW is in turn-round motions, the
turn-round could not be completed.
At greater distances, the laser light at the edge of the emitting range (angle) will
be weaker; therefore, the RC-2RW must be aimed correctly.

Tu rn On the RC-2RW by pressing the power switch.

Press the [turn-round] key on RC-2RW.

4

Total station starts searching and ends in the tracking mode where it is communicable with

this system.

Total station must be kept apart from reflecting planes such as glass
and white walls. Reflected light may prevent it from correct prism
searching and from auto tracking. In this case, change the power
mode of RC-2RW to the low power mode to decrease the output of
laser beam. To change the power mode, see “Low Power mode of

Note

Laser Beam” on page 17.
Ensure that RC-2RW remains as motionless as possible when the total
station is in turn-round motions. Total station otherwise may not be able
to search prism correctly, requiring extra time for the task.
The RC-2RW must be aimed so as to capture the total station within a
range of ± 35° in the vertical and horizontal direction during
communicating. (Refer to “Light detecting range” section.)

Stopping turn-around operations

Press the [ESC] key to terminate turn-around operation. After the key is pressed, turn-around
operation will continue for a short time before the Total Station comes to a stop.

16

Tracking Sensitivity of total station

(Only for GTS-800A/810A)

When executing turn-around operations at separation distances of 100 m or more from the total
station, the manufacturer recommends setting the tracking sensitivity of the total station to high
(H) in order to make operations more consistent.
On the low (L) and medium (M) settings, distance and weather conditions can increase the time
required for turn-around operations, and under certain adverse conditions total station operations
might even be impossible.

Low Power mode of Laser Beam

When the Total Station performs a turn-around function at a distance of approximately 10 m from
the RC-2RW, strong reflections of the pulsed laser diode (PLD) emission can prevent the Total
Station from searching the prism correctly. In this case, switch the laser to low-power mode to
reduce the intensity of such reflections.
In low-power mode, the range of the turn-round function is shorter than in normal-power mode.

To change the power mode

Tu rn the power ON while holding down the [ESC] key.
A buzzer will sound indicating that the RC-2RW is in low-power mode.
To return to normal-power mode, turn the power OFF, wait several seconds, and then turn the
power ON again.

Basic Operation

Reference : Turn-round motions:

When the turn-around key on the RC-2RW is pressed, the pulsed laser diode (PLD) in the emitter
produces a laser beam with a ± 5° cone pattern (Refer to “Light emitting angle” on page 14”.)
The RC-2H component of the Total Station has photo detectors on all four sides (front, rear, right
and left), allowing laser beams to be detected in any orientation. This detection ability extends to
approximately ± 30° in the vertical direction (refer to “Light detecting range” on page 15.)
Upon detecting laser emissions, the Total Station aligns toward the RC-2RW.
After horizontal alignment, the telescope is scanned vertically in order to target the prism and
initiate auto tracking.

Under certain conditions, the time required for communications can increase to the point
that turn-around operations require a long time to complete, and under certain
circumstances such operations might not even be completed properly. The following
conditions can adversely affect operation:

1) When units are used for communication over long distances or under poor atmospheric
and weather conditions (e.g., in strong direct sunlight; heat refraction such as occurs
near road surfaces and building surfaces on hot days; rain; fog, etc.)

2) When the aim of the RC-2RW is set incorrectly (refer to “Light emitting angle” on page

14.)

3) When the installation position of the prism and RC-2RW are separated (refer to
“Minimum Distance for Optical Communication” on page 18.)

4) When communication channel settings, or other settings, of the total station and RC­2RW are not matched or are set incorrectly (refer to “Table of item to be set” on page 13
and “Setting Mode” on page 19.)

5) When the total station is located in front of or to the side of glass or some other reflective
surface.

6) When, during turn-around operations, a person, car, or other object obstructs the light
path between the total station and the RC-2RW.

7) When the units are used over long distances, the RC-2RW is set to low-power mode
(“Low Power mode of Laser Beam” on page 17.)

8) When the dip switch settings on the RC-2RW are set incorrectly (refer to “Setting Mode”
on page 19.)

9) When the battery status display on the total station is flashing (low battery power)

Minimum Distance for Optical Communication

If you are not using the external detector(optional accessory), attach the prism unit as close as
possible to the RC-2RW. The minimum distance for optical communication is then determined by
the distance between the prism and the receiving window (dP), as described below.

Recommendation of the sealed-nickel-metal hydride (Ni-MH) battery

The use of Ni-MH batteries is recommended under low ambient temperature conditions. In
general, under cold conditions, the discharge characteristics of Ni-MH batteries are better than
those of alkaline-manganese batteries, thus providing longer operating time.

Precaution

Always clean the instrument after use.

Remove the dust using a brush, then wipe off with a soft cloth.
For cleaning the lens surface of the receiving window, use a cleaning brush, then use a clean
lintless cotton cloth. Moisten it with alcohol (or mixture with ether) to wipe gently in a rotational
motion from the center out.

To remove the dust on the surface of emitting window or the parts made by plastic, never use
thinner or benzine. Use a clean cloth moistened with neutral detergent.

Always make sure the instrument is completely dry before storing. Dry any moisture with a
soft, clean cloth.
