To avoid hazardous electrical shock, do not perform electrical

tests if there is any sign of shipping damage to any portion of the

front or rear panel or the outer cover. Read the safety summary

at the front of this manual before installing or operating the

3606E Message Terminal.

Inspect the shipping carton immediately upon receipt for evidence of
mishandling during the transit. If the shipping carton is severely
damaged or water stained, request that the carrier's agent be
present when opening the carton. Save the carton packing material
for future use.

Contents of the shipment should be as listed in the enclosed packing
list. If the contents are incomplete, if there is mechanical damage or
defect, or if the 3606E Message Terminal does not work properly,
notify your dealer.

After you unpack the 3606E Message Terminal, inspect it thoroughly
for hidden damage and loose components or fittings.

 Inspect the cable harness for stress, loose or broken wires, or

broken cable tires.

 Examine all the components for loose or missing hardware.

Installation Cabling

1.5 Cabling

For any installation it is required that all attached cables are shielded
and equipped with shielded connectors, which are properly
connected to the shield of the cable. Furthermore every shield
should have a low impedance connection to an electrical ground.

Before using the TT-3606E Message Terminal for the first time
check out that all cables are correctly wired and fastened.

Please notice that the DC-input range applies to the DC voltage
measured at the pin's on the power connector on the 3606E. This
means that the power cable characteristic should be taken into
account. The cable should allow the DC, measured at the input pin's
on the 3606E power connector, to stay within limits even though it
has to carry a current of 3 A.

Please notice, that the wires must be properly connected in the
connector and all pin’s for each power input must be connected to
the respective wire.

A cable using 2 mm2 (AWG 14) wire's of length 4 m fulfils the
requirements.

Please notice, that the cable connections must be properly installed.

Page 1-6 19Mar07

Mounting Installation

1.6 Mounting

The TT-3606E Message Terminal may be mounted in several ways.
If the mounting bracket is not used, the TT-3606E Message

Terminal may be flush mounted in a consol by using the 4 screw
holes on the rear.

The mounting bracket may be used either to mount the TT-3606E
Message Terminal on a horizontal surface or a vertical surface. In
both cases the angle can be adjusted in steps of 7.5°. This is done
by loosening the hand wheels slightly and then move the upper part
of the TT-3606E Message Terminal into the wanted angle. Please
remember to tighten the handwheels again.

When assembling the mounting bracket together with the TT-3606E
Message Terminal it is important that the small indications on the
cylinders are in-line with the indications on the rear of TT-3606E
Message Terminal.

When installing the TT-3606E on a vertical surface it is necessary to
mount the mounting bracket opposite the way it is mounted for
horizontal installation.

Please refer to the chapter describing the detailed mechanical
outlines of the TT-3606E Message Terminal and mounting bracket.

Service Disassembling

To get access to the main PCB, backlight PCB (piggy bag on the
main PCB) and computer board the following steps should be
followed:

WARNING

To avoid hazardous electrical
shock, do not touch the two
high voltage outputs of the
backlight inverter.

1. Make sure the mounting bracket is removed

2. Unscrew the 12 counter sunk screws on the rear and the 8 Sub­D stays.

3. Gently divide the front part and rear part from each other so that
the flex cable connecting the floppy with the main PCB on the
intermediate plate can be removed by releasing the zero­insertion force cable connector mounted on the main PCB (J15).

If it is necessary to remove/replace the main PCB it is necessary to

Special I/O Technical description

4.2 Special I/O

Special I/O ports have been implemented in the TT-3606E Message
Terminal in order to be able to support some extra features
compared to a standard PC. These are

• Disk change signal from floppy

• Backlight control of TFT flat-panel

• Watchdog

• Light sensor

• Reset of external keyboard

The table below indicates the diffent I/O ports

Address Direction Function
302h output light sensor sample and hold
302h input light sensor output
303h output control of

display backlight level
watch dog
keyboard reset

Table 8 Special I/O ports

The light level surrounding the equipment is determined by the light
sensor circuitry. A sample/hold of the light level is done by writing to
this port two times. The sampled value can then be determined by
reading this port afterwards.

An 8-bit A/D-converter is used with a reference level of 5V
(corresponds to A/D value FFh). The linear light sensor gives an
output in the range from 0V to 3,60V, thus the light level is in the
range from 00h to approximately C0h (255*5V/3,75V).

The tables below indicate the precise function of each bit in the
remaining ports.

19Mar07 Page 4-3

Technical description Special I/O

The “disk change signal “ is a hardware signal from the floppy drive
which during access to the floppy indicates (goes to 0) whether or
not the floppy has been changed. Can be used in the application
software to only read the FAT-table, when the floppy has actual
changed.

303h Function
0 (LSB) If 0 display backlight off else on
1 N/A
2 N/A
3 If toggled from 1 to 0 to 1 the light level of the

selected backlight(s) is(are) changed 1 unit (out of

100), /INC. Direction depends on bit 4

4 If 0 the light level is decreased when toggeling bit 3

(/DWN) else increased
5 Watch dog toggled when changing this bit
6 If 0 watchdog is disabled else enabled
7 (MSB) External keyboard enabled if 0 and disabled/reset if

1

Table 9 Control port (all 0 except bit 1,2 after power up)

The control port is used to set/reset the different bits in the
connected register. After power up all bits in this register defaults to
“0” except bit 1 and 2 which set to 1. This implies that the the display
backlight is turned on, the watchdog is disabled and the external
keyboard is enabled.

After the unit has booted, the application can enable the watchdog, if
the application program supports a watchdog surveillance circuitry. If
enabled it must be toggled every 0,5 second by changing the
appropriate bit as indicated above otherwise the unit will reset and
reboot.

Page 4-4 19Mar07

Special I/O Technical description

The reset possibility of the external keyboard can be used by the
application software for keyboard surveillance purposes.

The display backlight is controlled using electronic potentiometers
controlled using three signals:

CS : Chip Select
/INC: Increment
/DWN: Up/down selection

If CS is “1” the electronic potentiometer is selected and the /INC and
/DWN signals can be used to adjust the electronic potentiometer and
thus the light level. If CS is “0” these two signals will not imply any
change. Every time the /INC-bit is toggled the potentiometer is
adjusted 1/100 of its maximum value. The direction is controlled by
the /DWN-bit. If it is 0 the light level is decreased where as a 1 will
imply an increase when the /INC bit is toggled.

In this way the application can control the potentiometers to obtain
any of its 100 different positions/levels.

The /INC bit may not be changed more often than every 4 µsec.

Both potentiometers can be adjusted simultaneously in the same
direction by setting both CS bits to “1”.

To make sure that the position of the potentiometers are known by
the application software after power up both potentiometers should
be initialised with 100 pulses in either up or down. It is
recommended to decrease both backlights to the minimum level at
power up.

With respect to the display backlight there is a 1:1 relation from
potentiometer position 100 (maximum light) down to approximately

60. Below 60 the display backlight level will not change.

19Mar07 Page 4-5

Technical description Special I/O

In order to completely turn off the backlight it is necessary to use the
display backlight on/off bit and set it to 1.

A way to cope with the display backlight characteristic is to have two
display setups/styles: one used during daylight (bright colors, but not
red) and one used during night (red characters and graphics on a
black background).
