1.3 POWER SUPPLY
Power can be supplied in three ways:
•By connecting the µGRAPH displayboard to the MICROGATE battery charger. In this way it is
possible to supply a mains graphic displayboard and to keep the batteries charged at the same
time. This guarantees perfect functioning also when the mains power supply is interrupted. The
ACC062 adaptor accepts an input of alternate current at 50 or 60Hz, within a range of 100 and
240 Volts
•By using the internal batteries of the displayboard. In this case autonomy is usually above 30
hours of continuous functioning (depending on the type of display used).
•By connecting the displayboard to any continuous current supply (whether steady or not)
between 10 and 30 Volts which is able to supply at least 30W peak power and about 4W
average power. A car battery guarantees several days’ autonomy.
If 2 or more µGRAPH displayboards must be powered, a single dedicated adaptor can be
requested from MICROGATE.
Important note: the adaptor ACC062 for the µGRAPH displayboard is not suitable for outdoor
use. Consequently Microgate does not accept any responsibility for damage to persons or things
due to incorrect use of the adaptor.
1.3.1 Battery Recharge
If the batteries are low, either the discharge/recharge or the immediate recharge procedure can be
carried out.
In the first case, the batteries are first discharged and only subsequently recharged. This allows the
batteries to maintain their original capacity over a long period.
To select discharge/recharge, keep the “START STOP (MODIFY CHARGE/DISCHARGE)”
button on the control panel pressed down for at least 2 seconds with the displayboard
switched off after connecting an external power source to the connector SUPPLY.The operation
will take from a minimum 7 hours to a maximum of about 10 hours, depending on the initial battery
charge level.
If you choose immediate recharge instead, the operation will last about 7 hours. However, although
this type of recharge takes less time, it should only be used in exceptional circumstances as it
shortens the life of the batteries.
To select immediate recharge, keep the yellow “LAP RESET (SETUP DIRECT CHARGE)”
button on the control panel pressed down for at least 2 seconds with the displayboard
switched off after connecting an external power source to the connector SUPPLY.
In both recharge modes it is possible to interrupt the process by pressing the START STOP and
LAP RESET keys simultaneously.

1.4 MODULAR ASSEMBLY
One of the greatest advantages of μGRAPH is that a number of displayboards can be put together
to increase the length of the strings and images displayed. A single μGRAPH has a resolution of
24x90 pixels, while connecting up 3 displayboards in series, for example, would make it possible to
show displays with a resolution of 24x270 pixels without spaces between one displayboard and the
next. Each displayboard is distinguished by its position (line and column) defined by the rotating
selector on the control panel. Consequently the selector of the first displayboard must be set at
ROW 0 and COLUMN 0, the second, to its right, at ROW 0 and COLUMN 1 (and so on) before
connecting up as described below.
This feature makes it possible to put together up to a maximum of 9 displayboards without taking
apart their external casing, and is quite easy to do.
DISPLAYBOARD A
DISPLAYBOARD B
PHASE 1:
a. Unscrew the 4 screws
in the side panel on the
right of
DISPLAYBOARD A and
remove the panel.
b. Unscrew the 2 locking
pins on the right of
DISPLAYBOARD A.
c. Pull out the two
sliding plates of
DISPLAYBOARD A as
far as they will go.
d. Screw in the 2 locking
pins of
DISPLAYBOARD A to
block the sliding plates.
e. Unscrew the 4 screws
in the side panel on the

B and remove the panel.
f. Unscrew the 2 locking
pins on the left of
DISPLAYBOARD B.

With this method it is also possible to join two or more lines of displayboards:
SERIAL 2
OUT
IN
SERIAL 1
OUT
SERIAL 2
IN
SERIAL 1
SERIAL 1
IN
SERIAL 2
OUT
PC - CHRONOMETER
In this configuration, each line of displayboards (maximum 9 per line) must be powered separately
through the first displayboard on the left. For data exchange between the lines, each first
displayboard must be connected to the one below it as in the figure: the signal coming from
SERIAL 2 of the displayboard above passes to SERIAL 1 of the displayboard below through a
special connection cable.
It is important to set the position of the displayboard on the rotating selector of the control panel. In
the example given, the first displayboard at the top left will have ROW 0 and COLUMN 0, the one
to its right ROW 0 and COLUMN 1, the first in the middle on the left ROW 1 and COLUMN 0, the
one to its right ROW 1 and COLUMN 1, the first at the bottom left ROW 2 and COLUMN 0 and
finally the one to its right ROW 2 and COLUMN 1.
Another possibility is to join two or more lines without external casing. This will increase not only
the length of the texts and images displayed, but also their width. Using 4 displayboards, for
example, gives a resolution of 48x180 pixels without breaks. Also in this case the position of the
displayboards must be set as for modular connections between two or more lines of μGraphs with
external casing (see above).
In this way it is possible to connect up to 16 lines of 9 displayboards, each for a total of 810x384
pixels. To be able to exploit this second possibility you are advised to contact MICROGATE for the
preparation of a special casing.

1.5 VIA RADIO SYSTEM
Some programs for the μGRAPH displayboard (see par. 0Program on p.18) make it possible to
use the Linkgate radio system connected through Decoder or DecRadio to the RADIO connector
situated on the µGRAPH control panel. Thanks to Linkgate it is possible to transmit START STOP
and LAP signals from a long distance and, in Program 0 (Normal), serial data.
For further information about the Linkgate system, consult the appropriate REFERENCE MANUAL.
In the following paragraphs, the possibility of using the via radio system will be indicated by a
section RADIO.
NOTE: To be able to use the Linkgate system in, Program 3 (Speedmeter) and Program 7 (Lap
Chronometer) the radio channel must be set in Program 0 (Normal) (see p.19) of the µGRAPH.
To be able to transmit control commands in Program 0 (Normal) via radio the DIP SWITCH on the
control panel must be set to RADIO (see par. 0 Serial Velocity Selector on p.6).
1.6 µGRAPH FIRMWARE
Every time it is switched on, μGRAPH displays the firmware version stored at that moment:
VERSIONE HARDWARE TIPO DI FIRMWARE VERSIONE FIRMWARE
HARDWARE VERSION FIRMWARE TYPE FIRMWARE VERSION

μGRAPH Displayboard User Manual 17
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
As can be noted in Figure 1, the numerical code of the firmware consists of 3 parts:
1. Harware Version, the first number: indicates the version of the motherboard which controls the
displayboard.
2. Type of Firmware, the second number, varies according to the programs that can be
performed with the displayboard acquired:
•1 = Standard Firmware
•2 = Standard Firmware with Program 10 (Self Timing) enabled
3. Firmware Version, the last two numbers: it is important to provide the MICROGATE staff with
this number if you require technical assistance.
1.6.1 Updating of Firmware
Free μGRAPH Firmware updating is possible by downloading the latest versions from the site
http://www.microgate.it or requesting them from MICROGATE.
Once the update file has been obtained, the operations to be performed are simple:
A. Switch off μGRAPH and set the rotating selectors ROW, COLUMN and PROGRAM to 15,15
and 15
B. Press the START STOP (MODIFY) e LAP RESET (SETUP) buttons simultaneously and, while
keeping them pressed down, switch on the displayboard (attention, the power supply must be
disconnected before switching on the displayboard); the led on the displayboard should slowly
blink red-green.
C. Connect the PC serial to the μGRAPH SERIAL 1 connector (using the 20m CAB010 cable or
the 2m CAB001)
D. From the PC run the uFlasher program containing the latest Firmware version. During
programming, the LOW BATTERY led on the displayboard turns ORANGE.
E. After about 2 minutes programming is over (uFlasher shows the message "Device successfully
programmed"). At this point, the led turns GREEN.
F. The μGRAPH Firmware has been successfully updated. Now you can switch off the
displayboard and change the settings on the rotating selectors ROW, COLUMN and
ADDRESS.
Any error in programming is indicated by the LOW BATTERY led on the displayboard, which turns
RED. In the unlikely eventuality that this should happen, simply repeat the procedure indicated
above.

2.1 PROGRAM 0(NORMAL)
By selecting the Program 0 (Normal) it is possible to command µGRAPH through the SERIAL 1
serial communication port or the RADIO connector.
The commands that can be given to µGRAPH are listed in par.0 Appendix A: µGRAPH Serial
Frame on p.39. We strongly recommend that the less expert should exploit the versatility of the
MICROGATE µBOARDS software to control µGRAPH correctly rather than making tedious
attempts at direct programming.
Note: the commands identified as ‘priority’ or ‘non-priority’ (or ‘strong’ and ‘weak’) should be
understood as being priority or non-priority in relation to the pause command. For example, a
‘Weak reset’command given after a command pause will be carried out only at the end of the
pause. A ‘Strong reset’command, on the other hand, will be carried out directly.
RADIO: When the Linkgate system via radio is used in Program 0 (Normal), the type of radio
signal used is different from that of the other programs and it is advisable not to exceed a
transmitter/receiver distance greater than 150m.

If 2 or more µGraphs commanded via Radio are being used, a special connector (ACC087) must
be connected to SERIAL 1 of the first displayboard. Without this connector pins 1 and 6 of the
Amphenol must be bridged.

Setup
In Program 0 (Normal), setup allows you to re-initialize all µGRAPH parameters to standard values
and to set the first column displayed on the displayboard. The latter configuration makes it possible
to use two or more displayboards placed side by side. For example, if the displayboard is the
second element of the line, the first column will have to be set to 9.
