CHAPTER 1 -Overview

Congratulations on your purchase of a MicroScribe™ G2, model G2, G2X, G2L, or G2LX. This

manual provides you with the information you need to quickly begin digitizing 3D objects.

Functional Overview

The Immersion® MicroScribe G2 is a powerful tool for performing 3-dimensional digitizing. Unlike

any system you have ever used before, the Immersion MicroScribe G2 employs a unique

mechanical linkage system, which provides support to its stylus. The MicroScribe G2 has been

designed with the user in mind. The counterbalanced arm and smooth gliding motion ensure

hours of fatigue-free and comfortable use. The unique stylus is comfortable to hold and allows for

easy manipulation between the fingertips.

The MicroScribe G2X offers higher resolution for more demanding applications. The MicroScribe

G2L offers a larger workspace for convenience and flexibility. The MicroScribe G2LX combines a

larger workspace and increased accuracy.

Technical Overview

The MicroScribe G2 communicates with a host computer through a standard USB port or RS-232

serial port. The system includes the digitizing arm unit, which houses the internal electronics, a

USB cable, a serial cable, an input device, and an external power module.

A series of optical encoders inside each of the joints work with a microchip in the base to send

the joint angles to a host computer, which calculates the position of the stylus tip in 3D space. A

foot pedal or hand switch can be attached to the rear panel of the digitizing arm to input data.

A number of software packages currently exist for the MicroScribe G2. See our web site,

http://www.immersion.com, for free software offers including MicroScribe Utility Software and the

Software Development Kit (SDK).

This chapter provides all of the information you will need to connect and begin using the

MicroScribe G2. Please read this section before unpacking your system to make sure that the

unit is handled correctly.

Unpacking and Assembly

Your MicroScribe G2 is a precision instrument and has been packed carefully to protect the

calibrated electronic and mechanical components. Due to shifting during shipment, we ask that

you take extra care when removing the MicroScribe G2 and accessories. We recommend you

unpack the MicroScribe G2 according to the instructions in this section.

PLEASE SAVE ALL OF YOUR PACKING MATERIALS. They are designed to protect your

MicroScribe G2, and should be retained in case the MicroScribe G2 should ever require

transporting or service. Should you choose to travel extensively with the MicroScribe, you may

wish to purchase a traveling case available from Immersion Corporation or from your MicroScribe

reseller.

You are now ready to unpack the MicroScribe G2 system. After you remove the top protective

sheet of foam, you will find that the system is packed as shown in Figure 1. The MicroScribe G2

fits into the large cutout and the accessories, such as the USB cable, power supply, serial cable,

and foot pedal, drop into the other cutout. Software is added above the system components and

should be located immediately above or below the top protective sheet of foam.

UNPACKING and ASSEMBLY PROCEDURE:

1. Remove the top protective sheet of foam, revealing all of the contents of the package.

2. Remove software packages (may be packed in shrink-wrapped or bubble-wrapped bags

containing disks and documentation).

3. To remove the MicroScribe from the foam materials lift it out, as shown in Figure 3.

•Grasp the MicroScribe G2 at its “elbow” with your left hand. Insert your right hand through

the hold (as shown) to lift it out of its shipping carton. The system weighs approximately

12 pounds, so be sure to have a firm grasp before beginning.

•Be aware that both the wrist/stylus assembly as well as the base will be unsupported and

free to move about. It is recommended to have the other hand ready to catch the arm as

it unfolds upon emerging from the packaging.

Figure 3 –Lifting the MicroScribe out of package.

Figure 4 –The MicroScribe in the Home

Position.

4. Set the base of the digitizer on a

hard flat surface (not on carpet

or fabric).

Place the stylus into the resting

hole on the MicroScribe. This

position is referred to as the

“Home Position.” See Figure 4.

Note that the stylus can only

insert one way into the retaining

socket. If you find that the stylus

is unable to reach the hole, do

not try to force it in. Twist the

final joint element in the

direction opposite to the hard

stop until the stylus can be

inserted.

On G2L and G2LX models, it is

possible to place the stylus in its

holder with the wrist roll joint 180

degrees out of proper alignment -this

will result in the stylus being at a

slightly non-perpendicular angle

relative to the desktop.

To correct this, remove the stylus

from its holder, spin it 180 degrees,

and place it back in the stylus holder.

Figure 5 –On G2L and G2LX model

MicroScribes it is possible to twist the

stylus in the home position.

Once the MicroScribe is securely in its home position, remove all of the other system

components from the packaging.

Moving the MicroScribe Around your Home or Office

_____________________________________________________________________________________

Figure 6 -The proper way to carry

a MicroScribe.

In addition to using the proper packaging

materials for transporting the MicroScribe to

and from various locations, you must also take

precautions when carrying it around your home

or office.

The stylus tip is sharp and can be dangerous if

not held still during transport. Always pick up

the MicroScribe by the base to prevent damage

to the arm, and carry the MicroScribe with both

hands to provide shock absorption for the

digitizer’s joints.

To pick the MicroScribe up, remove the stylus

from the stylus holder, supporting the “wrist”

section in one hand. Slip your other hand

through the opening and use it as a ‘handle’.

See Figure 6 for the correct carrying

procedure.

System Connections

To connect in USB mode:

1. Plug the end of the foot pedal or hand switch cable into the MicroScribe’s “Accessory” port.

2. By default the MicroScribe will draw power from the host computer via the USB cable, in which

case there is no need to plug in the separate power supply. Alternatively, power can be drawn

from the power supply. To do so insert the correct end of the power cable into the MicroScribe

port labeled “5V DC”. Plug the other end into a power outlet. Never use a power supply other than

the one provided with your MicroScribe, even if the voltage rating appears to be correct.

3. Plug the appropriate end of the USB cable into the MicroScribe port labeled “USB”. The other end

should go in a free USB port on your machine.

4. Place the MicroScribe in the home position. Press the “Home” button on the back of the

MicroScribe.

5. The MicroScribe is ready to connect to software. MicroScribe Utility Software (MUS) is included

on the Product CD in the box and can test basic MicroScribe connection settings.

6. Turn standby or hibernate off on the host machine to avoid losing connection to the MicroScribe.

If connecting to a USB hub, ensure that it is a powered hub.

To connect in serial mode:

1. Plug the end of the foot pedal or hand switch cable into the MicroScribe’s “Accessory” port.

2. Plug the appropriate end of the serial cable into the MicroScribe port labeled “Serial”. The other

end should go in a free serial port on your machine, numbered 1, 2, 3, or 4. Serial ports 5 or

greater may not be accessible by the device.

3. Insert the correct end of the power cable into the MicroScribe port labeled “5V DC”. Plug the other

end into a power outlet. Never use a power supply other than the one provided with your

MicroScribe, even if the voltage rating appears to be correct.

4. Place the MicroScribe in the home position. Press the “Home” button on the back of the

MicroScribe.

5. The MicroScribe is ready to connect to software. MicroScribe Utility Software (MUS) is included

Configuring the MicroScribe G2 for Digitizing

Placement of the MicroScribe

Now that your MicroScribe is connected and ready to use, you should situate it on your desktop,

workbench, or other workplace so that it is optimally configured for digitizing.

Figure 8 shows the recommended set-up for digitizing (see Figure 10 for a more detailed

example). Note that the rear panel of the MicroScribe G2 faces away from the user and that the

MicroScribe G2 is set up along the side of the digitizing workspace. This is completely arbitrary,

since the MicroScribe can digitize in any volume it can reach. We suggest that you first try a

configuration like the one in Figure 10, and then customize the positioning of the MicroScribe G2

based on your experience and special needs.

Figure 8 -The recommended workspace for the MicroScribe.

We suggest that you work on one side of the unit, with the center of your workspace about

halfway from full extension of the arm.

Bolting the MicroScribe down (optional)

The MicroScribe G2 is designed to sit securely on a flat, rigid surface. You may also mount it

rigidly to your work surface by using a single bolt (size 3/8 –16) inserted through your work

surface up through the center of the MicroScribe base. Be sure that the bolt you use does not

extend too far into the MicroScribe. The bolt used should extend NO MORE than ½” (1.25 cm)

from the surface to which the MicroScribe is being mounted. Longer bolts could interfere with

internal electronics and damage the system. In other words, the bolt length should be the

thickness of the surface you are mounting to plus up to ½” (1.25 cm) to attach to the MicroScribe.

Do NOT bolt the MicroScribe down to an electrically conducting surface unless that surface is

grounded and not subject to electrical interference or noise. You may also use a large tripod

mount, as the threading on the mounting hole should correspond to standard tripod mounts.

Changing Stylus Tips (optional)

Should you need to replace the digitizing tip which screws into the end of the stylus, simply

remove it by unscrewing it counterclockwise. Only the silver portion of the tip can be removed. Be

sure that when you replace the tip that it is tightened firmly enough to avoid coming loose during

use.

Replacement tips and alternate tips are available directly from Immersion Corporation or an

authorized reseller. Please contact Immersion for details.
