4.4 Bluetooth Wireless Technology

Precautions concerning Bluetooth wireless technology

• Use of this technology must be authorized according to telecommunications regulations of the country where the instrument is being used. Contact your Sokkia agent in advance.

• Sokkia is not liable for the content of any transmission nor any content related thereto. When communicating important data, run tests beforehand to ascertain that communication is operating normally.

• Do not divulge the content of any transmission to any third party.

Radio interference when using Bluetooth technology

Bluetooth communication with the SRX uses the 2.4 GHz frequency band. This is the same band used by industrial, scientific, and medical (ISM) equipment such as microwaves, portable premises radio equipment (license required) and portable specified low-power radio equipment (license-exempt) used in factory production lines, etc.

• Before starting transmission, check that operation will not take place within the vicinity of portable

premises radio equipment or specified low-power radio equipment.

• In the case that the instrument causes radio interference with portable premises radio equipment,

terminate the connection immediately and take measures to prevent further interference (e.g. connect using an interface cable).

• In the case that the instrument causes radio interference with portable specified low-power radio

equipment, contact your Sokkia agent.

Although a radio station license is not required for this instrument, bear in mind the following points when using Bluetooth technology for communication.

● Do not use within the vicinity of the following:

•Industrial, scientific, and medical (ISM) equipment such as microwaves and pacemakers.

• portable premises radio equipment (license required) used in factory production lines etc.

• portable specified low-power radio equipment (license-exempt)

•IEEE802.11b/IEEE802.11g standard wireless LAN devices

The above devices use the same frequency band as Bluetooth communications. As a result, using the SRX within proximity to the above devices may result in interference causing communication failure or reduction of transmission speed.

• Refrain from using the SRX within proximity to televisions and radios Televisions and radios use a different frequency band to Bluetooth communications. However, even if the SRX is used within proximity to the above equipment with no adverse effects with

regard to transmission, moving a Bluetooth-compatible device (including the SRX) closer to said equipment may result in electronic noise in sound or images.

4. PRODUCT OUTLINE

Precautions regarding transmission

● For best results

•When using the On-demand Remote Control system, perform communication within a line-ofsight distance of approximately 300m. The usable range becomes shorter when obstacles block the line of sight, or devices other than the On-demand Remote Control system, such as PDAs or computers, are used. Wood, glass and plastic will not impede range becomes shorter. Moreover, wood, glass and plastic containing metal frames, plates, foil and other heat shielding elements as well as coatings containing metallic powders may adversely affect Bluetooth communication and concrete, reinforced concrete, and metal will render it impossible. Use a vinyl or plastic cover to protect the instrument from rain and moisture.

•The direction of the Bluetooth antenna can have adverse effects upon usable range. For best results make sure that the antennas of both the SRX and the companion device are as vertical as possible and visible to one another. When this is not possible, better results can be obtained by pointing the antenna vertically towards the ground.

communication but the usable



• Perform communication at a distance of 2m or more from electrical devices such as audio-visual equipment and office automation equipment. In the case of microwave ovens, which are especially su scept ible to int erfer ence, this d ista nce sh ould be inc rease d to 3m . Moreover, operation near televisions and radios may lead to problems with reception.

• Ensure that cellular phones are at least 20cm from the SRX Bluetooth module during operation.

• Change location when proximity to a wireless device or broadcast station results in communication failure.

When using the SRX near IEEE802.11b or IEEE802.11g standard wireless LAN devices or other devices that operate on the 2.4GHz ISM band, interference may result, causing transmission speed to slow or even disrupting the connection completely. Turn off all devices not being used.

● Reduced range due to atmospheric conditions

The radio waves used by the SRX may be absorbed or scattered by water and airborne moisture. The signal may be weakened by exposure to rain, fog, and moisture from the human body with the limit of usable range becoming much lower as a result. Moreover, as wireless devices lose signal strength when close to the ground, perform communication at as high a position as possible.

11.TARGET SIGHTING

The target can be automatically sighted using the Auto Pointing function or manually sighted by the operator using the peep sight and telescope. The Auto Pointing function automatically sights the target and does not require you to focus the telescope. The SRX analyses the image of the prism in the field of view and moves the telescope to sight the center of this prism.

•The search method can be set.



"12.1 Auto Tracking Settings"

 Caution

• The instrument emits a laser beam until the center of the prism is sighted.



• Auto Pointing can only be performed when a prism or sheet is used as the target. For reflectorless measurement, the target must be sighted manually.

• Use reflective prisms/reflective sheets from Sokkia for higher precision measurement.

• Auto Pointing cannot be performed if the prism is located at the zenith. In this case, manually sight the target.



"11.3 Manually Sighting the Target"

• If more than one prism is located in the field of sight during Auto Pointing, an operation error will occur and the SRX will not be able to find the target.

• A prism beyond glass cannot be searched because a measurement error occurs.

• If an obstacle blocks the laser beam path between the SRX and the prism, SRX cannot find the target correctly.

• If strong light shines directly into the objective lens, measurement cannot be performed correctly.

• Position the prism in alignment with the objective lens. In short distance measurement especially,

make sure to align the prism with the objective lens (within 10 to 15°) to obtain the correct result. A prism with a prism constant of -40mm can eliminate the error caused by tilted prism.

 Aspect of the 360° Prism

The 360° Prism should be set up so that a pair of hexagonal points on the rubber flanges of the prism are aligned with the sighting direction of the SRX (see the diagram below).

11. TARGET SIGHTING

 Accu. search

Compared to Digital Imaging Mode ("Rapid" setting), the analysis of the prism image in Optical Imaging Mode ("Fine" setting) is finer and the criteria for completing sighting are more stringent. "Rapid" mode should be used when supporting the pole by hand if "Time out" is displayed before the SRX completes sighting as a result of vibration, or, completing Auto Pointing takes too long.

 Srch method

Selects search before distance measurement option. When set to "G.S." the SRX will search for the target in the area specified in the Search area tab. When set to "R.C.", the SRX will wait for a Turning command to be issued from the RC Controller before starting Auto Pointing. Both methods can be used to sight the target.

2. Set the area in which to perform target sighting in

the Search area tab. Drag the box to specify the desired or area or input vertical and horizontal angle values. Angle values can only be specified in 1°30’ steps (e.g. 15°00’, 16°30’, 18°00’ etc.). Input values not conforming to this format will be automatically rounded up.



• When sighting the target, strong light shining directly into the objective lens may cause the

instrument to malfunction. Protect the objective lens from direct light by attaching the lens hood.

XPROCEDURE

1. Look through the telescope eyepiece at a bright and

featureless background. Turn the eyepiece clockwise, then counterclockwise little by little until just before the reticle image becomes focussed. Using these procedures, frequent reticle refocussing is not necessary, since your eye is focussed at infinity.

2. Use the peep sight to bring the target into the field of

view. Turn the vertical and horizontal jogging knobs for fine sighting adjustments.

3. Turn the telescope focussing ring to focus on the

target. Turn the vertical and horizontal fine motion screws to align the target with the reticle. The last adjustment of each fine motion screw should be in the clockwise direction.

4. Readjust the focus until there is no parallax

Readjust the focus with the focussing ring until there is no parallax between the target image and the reticle.

 Eliminating parallax

This is the relative displacement of the target image with respect to the reticle when the observer's head is moved slightly before the eyepiece. Parallax will introduce reading errors and must be removed before observations are taken. Parallax can be removed by refocussing the reticle.

12. MEASUREMENT WITH AUTO TRACKING

With the Auto Tracking function, an SRX, sighted on the target using Auto Pointing, will following that target as it is moved from measurement point to measurmeent point. The On-demand Remote Control System is recommended for high performance Auto Tracking measurement.

 Caution

• The instrument emits a laser beam during Auto Pointing and Auto Tracking operation.



• Auto Pointing can only be performed when a prism is used as the target. Auto Tracking is not

possible with reflective sheet and reflectorless measurement

• Use reflective prisms from Sokkia for higher precision measurement.

• If more than one prism is located in the field of sight during Auto Tracking, an operation error will

occur and the SRX will not be able to find the target.

• The prism beyond the glass can not be searched because measurement error occurs.

• If an obstacle blocks the laser beam path between the SRX and the prism, SRX cannot find the

 Caution

• When using the laser-pointer function, be sure to turn OFF the output laser after distance

measurement is completed. Even if distance measurement is canceled, the laser-pointer function is still operating and the laser beam continues to be emitted. (After turning ON the laser-pointer, the laser beam is emitted for 5 minutes, and then automatically switches OFF.)



• Make sure that the target setting on the instrument matches the type of target used. SRX

automatically adjusts the intensity of the laser beam and switches the distance measurement display range to match the type of target used. If the target does not correspond to the target settings, accurate measurement results cannot be obtained.

• Accurate measurement results cannot be obtained if the objective lens is dirty. Dust it off with the

lens brush first, to remove minute particles. Then, after providing a little condensation by breathing on the lens, wipe it off with the wiping cloth.

• During reflectorless measurement, if an object with a high reflective factor (metal or white surface)

is positioned between the SRX and the target, accurate measurement results may not be received.

• Scintillation may affect the accuracy of distance of measurement results. Should this occur, repeat measurement several times and use the averaged value of the obtained results.

16. RESECTION MEASUREMENT

 Resection calculation process

The NE coordinates are found using angle and distance observation equations, and the instrument station coordinates are found using the method of least squares. The Z coordinate is found by treating the average value as the instrument station coordinates.

16. RESECTION MEASUREMENT

 Precaution when performing resection

In some cases it is impossible to calculate the coordinates of an unknown point (instrument station) if the unknown point and three or more known points are arranged on the edge of a single circle.

An arrangement such as that shown below is desirable.

: Unknown point : Known point

It is sometimes impossible to perform a correct calculation in a case such as the one below.

When they are on the edge of a single circle, take one of the following measures.

(1) Move the instrument station as close as possible

to the center of the triangle.

(2) Observe one more known point which is not on the

circle.

(3) Perform a distance measurement on at least one

of the three points.



• In some cases it is impossible to calculate the coordinates of the instrument station if the included

angle between the known points is too small. It is difficult to imagine that the longer the distance between the instrument station and the known points, the narrower the included angle between the known points. Be careful because the points can easily be aligned on the edge of a single circle.

17.SETTING-OUT MEASUREMENT

Setting-out measurement is used to set out the required point. The difference between the previously input data to the instrument (the setting-out data) and the measured value can be displayed by measuring the horizontal angle, distance or coordinates of the sighted point.

The horizontal angle difference distance difference, and coordinate difference are calculated and displayed using the following formulae. Horizontal difference Displayed value (angle) = Horizontal angle of setting-out data - measured horizontal angle Displayed value (distance) = measured horizontal distance x tan (horizontal angle of setting out data

- measured horizontal angle)

Slope distance difference Displayed value (slope distance) * = measured slope distance - slope distance setting-out data * Horizontal distance or height difference can be input in the above formula.

Coordinate difference Displayed value (coordinates)* measured N setting-out coordinates - N coordinates of setting-out data * E or Z coordinates can be input in the above formula

Height difference (REM setting out measurement) Displayed value (height) = measured REM data - REM data of setting out data

• Setting out data can be input in various modes: slope distance, horizontal distance, height

difference, coordinates and REM measurement.

• It is possible to allocate softkeys in the Setting-out measurement menu to suit various applications

and the ways that different operators handle the instrument.
