Keypad Layout

The keypad of the TECH 2 contains 27 keys. Within these keys are 23 keys that are pre-defined and four keys which are

referred to as soft keys. The soft key usage will change depending on which part of an application is being used.

Following is a definition of the key usage for the pre-defined keys.

Soft Keys

There are four keys on the TECH 2 that will have changing usage within an app lication. Soft key functions are software

driven. This means that the soft key function may change in different areas of the software. The left most soft key at the

Main Menu will be used to Clear Vehic le, while in Snapshot the same key position may change Units. The ability of the

soft keys to perform different tool operations at different times increases the versatility of the TECH 2.

Page 0C–8

TECH 2 Page 0C–9

Selection Keys

The arrow keys are used for screen movement to make a selecti on. There are four arrow keys. The Up and Down arrows

move the highlight bar one line at a time. If they are held, the highlight bar will scroll. The Left and Right arro w keys will

move the highlight a page at a time. Left arrow moves the hi ghlight up (previous page) and Right arrow moves the

highlight down (next page). The arrow keys are used to move the highlight bar to a position to make a selection, or to

move the display to allow more information to be viewed.

Action Keys

There are a group of keys that are referred to as Action ke ys. As the name implies, action keys will make an action take

place on the TECH 2 tool. The action keys are YES, NO, ENTER, and EXIT.

YES — Confirms a positive response to a question.

NO — Confirms a negative response to a question.

ENTER (2 keys) — Indicates a selection has been made.

EXIT (2 keys) — Returns the user to a previous menu selection.

Function Keys

The function keys (F0 - F9) allow direct selection of a cho ice from a menu.

Help Key

Help (?) accesses a tool help function that is specific to the current operation of the TECH 2.

Control Keys

There are two keys that are used to control the TECH 2 itself. These are the SHIFT and PWR (Power) keys. The SHIFT

key will access screen contrast control. To adjust contrast during the current power cycle of the TECH 2, use the

following procedure.

Press the SHIFT key (The yellow light will turn on).

Use the Up arrow to Increase screen brightness and contrast or the Down arrow to Decrease screen brightness and

contrast.

Press the SHIFT key (the yellow light will turn off).

This procedure will only adjust the contrast for the duration of this power cycle of the TECH 2. If the power is turned off

and then back on again, the contrast will change to a default value. The default setting is covere d in the TECH 2 User’s

Guide.

Be aware that if the yellow SHIFT light is on, only the Up/Down arrow keys and the EXIT keys are active.

There is a PWR (Power) switch for TECH 2 that will control turning the TECH 2 on and off. A green ind icator will

illuminate when the TECH 2 is s witched on.

Thumb Action

The TECH 2 is designe d for one handed operation. The unit is balanced to allow one hand to comfortably hold and

operate the tool. Straps on the sides of the tool are adjustable to help hold the TECH 2 in one hand. The keypad

configuration is designed for thumb usage while holding the tool in either the left or right hand. It is suggested to use the

selection and action keys instead of the function keys, as some TECH 2 screens require making selections from a list on

screen. In these cases there may not be a function key equivalent.

Legend:

1. PCMCIA Release Button 3. Empty Lower PCMCIA Slot 1 5. PCMCIA Cover

2. In Use Upper PCMCIA Slot 0 4. TECH 2 PCMCIA Card 6. Underneath Side of TECH 2

The TECH 2 uses a Personal Computer Memory Card Industry Association (PCMCIA) standard memory card for storage

of diagnostic functions and applicati ons. The memory card has a capacity of 32 Megabytes. T he PCMCIA card is

accessed through a door on top of the TECH 2, and should not normally require removal. There are two PCMCIA slots in

TECH 2, slot zero which is closest to the screen and the second slot that is identified as slot one. To remove the card,

push the arrow button pointing to card to be remove d. Cards are notche d to allow insertion only one way. When re-

inserting the card make sure that it fully seat s into the TECH 2.

If you are using a 32 Megabyte PCMCIA card, the card should be installed into slot zero. If you are using 2 PCMCIA

cards, one in each slot, you can switch between cards by pressing the SHIFT key, then press either the RIGHT or LEFT

arrow key. TECH 2 will then toggle between the card in slot 0 to the card in slot 1. Once TECH 2 has toggled between

cards, press the SHIFT key again.

The TECH 2 has the capabi lity of storing two snapsh ots. T his will allow comparison of before/after type conditions on a

vehicle being serviced.

NOTE

The PCMCIA card is sensitive to magnetism and

static electricity so care should be taken in the

handling of the card.

A write protect slide mechanism is on the top edge of the ca rd. T he correct position is to the middle of the card

(unlocked). If the write protect is in the locked position, snapshots will not be able to be stored, and Service Programming

System (SPS) will not work.

TECH 2 and PCMCIA card can be updated b y connecting to Technical Information System (TIS).

The software that operates the TECH 2 is stored on the PCMCIA card. The contents of the card are not distinct

applications. All of the applications share a single database of informatio n on the PCMCIA card.

TECH 2 Page 0C–11

Vehicle Communication Interface Module

The TECH 2 uses a Vehicle Communication Interface (VCI) module, located in the bottom of the unit to act as an

interface between the vehicle and the internal workings of the TECH 2. This allows the TECH 2 to communicate to many

different types of data systems on vehicles.

Data is transmitted between the vehicle and the TECH 2 through the DL C cable. Power for the TECH 2 is also sent

through the VCI module. Power can either come through the DLC cable or from the power jack on the bottom of the VCI

module. Internally, the VCI module protects the TECH 2 against reverse polarity power connections.

During normal usage of the TECH 2, there is no reason to remove the VCI module. In the future, if different types of data

communication are used on the vehicle, the VCI module could be changed to extend the useful life of the TE CH 2 even

further. To remove the VCI module, refer to the TECH 2 User's Guide.

1.2 Connections

To use the TECH 2 (4), proper connections will need to

be made. These connections include power and the DLC

(1). Power for the TECH 2 normally comes from the DLC.

If no power is available at the DLC, or if using the TECH 2

away from the vehicle, another source of power should be

used. On-vehicle power connection may also come from

the cigarette lighter adapter or from the battery clip

adapter. When using one of the adapters (2), connect to

the jack at the back of the DLC cable (3) connection. The

12V adapters have fuses in them to help prot ect the

TECH 2 wiring.

The TECH 2 AC po wer adapter should NOT be used

while the TECH 2 is connected to a vehicle as data errors

may occur. Instead, the AC power adapter is designed to

be used while operating TECH 2 away from vehicle. T he

TECH 2 will work between 8-20 volts and about 0.75

amps.

The TECH 2 will also at times be require d to be

connected to a Personal Computer (PC) to communicate

with the Technical Information System (TIS). This

connection is made via the RS-232 comm unication port.

A hardware key is required when the Service

Programming System (SPS) is being utilised
