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

a. Connect the power socket (7 pole amphenol, the cable with the larger diameter) of DISPLAYBOARD A to the external connector SUPPLY of DISPLAYBOARD B.
a. b. Connect the REAR SERIAL socket (6 pole amphenol, the cable with the smaller diameter) of
DISPLAYBOARD A to the SERIAL 1 connector of DISPLAYBOARD B.
c. Bring the two displayboards together so that the sliding plates of DISPLAYBOARD A fit into the slot designed for them in 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. 0
Program 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:

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.

2.2 PROGRAM 1 (MEMORY PROGRAM)
Program 1 allows you to automatically run the previously set program. This program must be
stored while µGRAPH is in Program 0. To store the program, send the command 'Program Start',
then the sequence of commands that make up the program, finally the 'Program End' command. Besides the normal commands, a program can contain loops with instructions automatically repeated more than one time or an infinite number of times. The commands to be repeated must be preceeded by the command 'Label', which makes it possible to define the position of the program from which the commands to be repeated start. This command sequence must end with
the command 'Loop-Goto' which allows you to define the number of times the loop must be
repeated.

2.3 PROGRAM 2 (CHRONOMETER)
In this mode µGRAPH works as a typical chronometer set to 1/100 of a second.
• With Start (manually, from input or via radio) the chronometer starts.
• With Lap (manually, from input or via radio) the chronometer shows an intermediate time
for 5 seconds.
• With manual Start or Stop from input or via radio the chronometer stops.
• Now it is possible to set the chronometer to zero by pressing Lap.
If the chronometer is not set to zero, it will start from the value shown.
If the Autoreset time has been set to follow every Stop (or manual Start), the chronometer resets itself to zero after the preset time.
NOTE: If the printer is connected, times are printed, coupled to a progressive counter that is
automatically set to zero every time mode 2 is selected or µGRAPH is switched off.
RADIO:
Program 2 (Chronometer) can also be used with a Linkgate system via radio. After the
radio channel has been correctly set (see par. 0
Program 0 (Normal) on p.19) the µGRAPH
displayboard will also accept START, LAP and STOP signals coming from Linkgate.

2.4 PROGRAM 3 (SPEEDMETER)
This mode allows you to measure the speed on the basis of any length. The speed is calculated on
the basis of the measurement of the time interval between two L
AP-STOP input or via radio or
manual
LAP-START impulses. So you need only place two photocells at the desired distance and
connect them to the Lap and Stop inputs. If the bidirectional mode has been set, the measurement base can be run in both directions. Bidirectional mode is not recommended if it is not essential. The system is able to manage up to 20 transits at the same time in the measurement base. If a delay has been set for the activation of the stored program (see "Setup" below), when this time is completed after the last measurement made, the display of the sequence stored as program is automatically started. This auxiliary function allows automatic display of information or advertising during the pauses between transits. If the printer is connected, the speeds are printed, coupled to a progressive counter which is automatically set to zero every time you enter mode 3 or µGRAPH is switched off.
NOTE: obviously, speed measurement precision depends on the accuracy with which time is
measured on the measurement base. To have a precision of 0.025 Km/h up to speeds of 130 Km/h, you need only place the photocells at least 10 m apart (using MICROGATE photocells). Increasing the distance increases measurement precision.
RADIO: As well as giving the manual LAP and START signals or input LAP or STOP, a Linkgate
system via radio can be used. In this case the following options are available:
A. Use of 2 Polifemo photocells and 2 Encoders or EncRadios. The signal of the first
EncRadio must be set on LAP (any), and that of the second on STOP.

In the example shown in Figure 3, 2 Polifemos connected to EncRadio through Banana Cube have
been used.
It is important to point out that if the EncRadios (or Encoders) have been set on LONG
transmission signals, the traveling time of the length base cannot be less than 3 seconds while the time cannot be less than 1 second if SHORT signals are used.
B. Use of 2 Polifemo photocells and 1 Encoder or Encradio. The first photocell must be
connected (2 metre CAB050 cables or 20 metre CAB048 cables) to the Red and Black
banana jacks of the Encoder and the second to the Green and Black banana jacks. The rotating selector for the selection of the signal on the Encoder must be set to LAP E.
With this option it is not possible to exploit the bidirectionality of the system or to have more than one competitor in the measurement base.

2.5 PROGRAM 4 (COUNTDOWN)
In this mode µGRAPH simulates a timer for the start. The beeper is activated at -10 seconds, -5, ­4, -3, -2, -1 and 0 seconds from the set start time. Normally, the built-in beeper is too weak. You are therefore advised to connect the loudspeaker to the external socket on the side panel. The start device (starting gate or other) should be connected to the START-STOP-LAP-INPUTS input. At each start the starting time (minutes, seconds and thousandths) and the deviation in minutes, seconds and thousandths relative to the scheduled starting time (with the sign - for early start, + for delayed start) are displayed in sequence.
NOTE: the first start is given at the first net minute shown after Program 4 (Countdown) has been
activated.
Setup
The time intervals between successive starts, the green light time and the time displayed can be pre-set (so as to synchronize the internal clock with other devices, usually the main chronometer). The period between each start is set to 0 and the countdown from -10 seconds starts when the L
AP-SETUP key is pressed (or when the Lap input is activated).
In this way the start sequence can be set manually. In this case deviation from the scheduled start time is neither displayed nor printed.

2.8 PROGRAM 7 (LAP CHRONOMETER)
Program 7 allows lap times timing. At each Start or Stop impulse (indifferently) the chronometer takes the time from the previous impulse and restarts automatically from zero. Time continues to be displayed for 8 seconds, then the running time appears again. The input and Lap key reset the chronometer to zero.
NOTE: If the printer is connected, times coupled with a progressive counter which is automatically
set to zero every time Program 2 (Chronometer) is entered or μGRAPH is switched off, are printed.
RADIO: As well as giving the manual or input START, STOP and LAP signals, a Linkgate system
via radio can be used (after correctly setting the radio channel in the menu of Program 0 (Normal)). The displayboard accepts any LAP signal.

2.10 PROGRAM 10 (SELF TIMING)
NOTE: This mode is available only on displayboards purchased with the Self-Timing option.
2.10.1 Starting Coin Box
The Starting coin box must be connected to the starting gate by connecting the special cable to the "GATE" socket on the bottom of the coin box and to the starting gate (black and green sockets). The coin box must also be connected to the finish through the"LINE" connector. For the connection between start and finish use a four-pole cable (the only specification for the cable: the total resistance of each cable should be less than 50 ohm - for example, for a 1000 m line, cables with a
section of 0.25 mm2 or more are sufficient). The jacks supplied must be connected to the ends of the cable, connecting poles 1, 2, 4, 6 of the jacks one at a time. Poles 3 and 5 are not used. The third socket on the coin box is for powering a self-regulating warming resistance inside the coin box itself. This prevents the blocking of the mechanical parts of the coin box when wet or snow-covered coins are used and the external temperature is particularly low. Although it is not normally neccessary to power the resistance, you are strongly recommended to do so. The resistance must be powered at 24V (either direct or alternate). Consumption is high at the beginning (200W max). Then it stabilises at about 20W (exact consumption depends on the external temperature). The two resistance poles are connected to pins 1+2 (short-circuited) and 4+5 (short-circuited) of the "HEATING" jack.
NOTE: It must be stressed that if the warming resistance is not used, it is not necessary to power
the coin box.
2.10.2 Finish displayboard
Connect the line from the Start (see previous paragraph) to the SELF-TIMING socket of THE displayboard with the jack supplied. Connect the photocell to the S
TART-STOP-LAP INPUTS socket of the displayboard with the cable
supplied. If you wish to take the exit speed, the intermediate time photocell must also be connected. Consequently a suitable wire must be used with a connection box to connect the start and intermediate time photocells. With regard to power supply, remember that there are three different ways of powering the MICROGATE Self-Timing (see also par. 1.3 Power supply on p.9): A. By connecting the displayboard to the MICROGATE battery recharger/supply unit. In this way
the Self-Timing is powered from the mains supply and simultaneously the batteries are kept charged by a trickle current. This guarantees perfect operation even if the mains supply is interrupted.
B. By connecting the displayboard to any direct current source (whether stabilised or not) between
10 and 40 Volts, able to provide at least 4W peak power. A car battery guarantees a few days of autonomous use.
C. By using the batteries built into the displayboard. In this case it is necessary to recharge the
batteries daily with the special battery recharger.

2.10.3 Printer
It is possible to connect a printer with a built-in ticket cutting device to MICROGATE Self-Timing. The printer must be connected to the SERIAL 2 port on the side panel of µGRAPH. At the finish, for every competitor a card is printed for him/her to take. On the card the following information appears:
• Two lines pre-set by the user (see below)
• Date, time and the competitor’s progressive number
• Competitor’s time
• Best race time
• Competitor’s exit speed (if the intermediate photocell has been installed)
• Best exit speed
The progressive number, the best time and the best speed are reset to zero by switching off μTAB or by passing to a mode different from Program 10. To set the first two lines which appear on the printer it is necessary to use a Personal Computer and send the appropriate command to µGRAPH (on this subject, see par. 3.1.1 µGRAPH Serial Protocol – Self Timing on p.40). The operation is easy and immediate if you use the MICROGATE µBOARDS program.
2.10.4 Functioning of Self-Timing Systems
To activate Self-Timing just connect the system as previously described and switch on the displayboard (Power switch), making sure that the "Program" switch is on 10 (Self-Timing). The system starts functioning automatically when the first coin is inserted. The light on the coin box can have three states:
• Red: track stopped (any possible start has no effect)
• Green: track free, the athlete can start
• Blinking Red/Green: track free, but less than 10 seconds are left to start.
The green light is coupled to a free track beeper. The beep becomes more frequent when less than 10 seconds are left to start (blinking Red/Green). After every start the track can be stopped for a time which can be changed as desired (see next paragraph), even if there are credits left. During this time the light remains red, and no start made will be considered. The light remains red even if there are four competitors on the track simultaneously. If a competitor falls and does not finish the run, his/her time is automatically cancelled after a maximum time that can be changed as desired (see next paragraph).
It is also possible to set a minimum race time under which Stop signals are not accepted. This minimum time has two functions. First it serves the purpose of eliminating "impossible" times (obtained, for example, if all the gates are “missed”); secondly, it prevents the time of a competitor who has abandoned the race from being assigned to another competitor who has overtaken him/her.
NOTE: It is not necessary to wait until the track is free before inserting the coins. The system
automatically allows the number of transits that have been paid.

values have a special meaning: - 10 minutes and 0 seconds: the light remains green for an infinite time after each enablement until the enablement is used with a start.
- 0 minutes and 0 seconds: the track is always free and coins do
not need to be inserted. This setting is useful when you want to use the system to time a race, or when the payment of the races is not necessary or is managed by other devices. The light turns red only after each start for the minimum time between one start and the next.

2.10.6 Default value of the Self Timing editable parameters
When µGRAPH is delivered or after each global initialization (see
2.10 Program 10 (Self Timing) p.19), the configurable parameters are automatically set to the following values (often suitable for many applications):
• Maximum Race Time 1' 30"
• Minimum Race Time 0' 0" (Stop is always enabled)
• Green Light Time 1'
• Minimum Start between two starts 0' 20"
• Speed Base Length 10 meters
• Speed unit Km/h
• Delay Time of Program Activation 0' 15" (Attention: obviously, the program does not
start if it has not been previously stored)
• Printer paper length 0
2.10.7 Some suggestions
• Avoid reducing the minimum time between two starts excessively as it can be dangerous to
have racers starting at very short time intervals.
• Also avoid excessive reduction of the green light time, that is, the time that each racer has for
starting. Although the reduction of this parameter makes it possible to reduce the waiting time at the start, too short a time can be unpleasant for customers, who find themselves obliged to rush their starts.
• If the photocell is used to take the exit speed, place it at least 8 - 10 meters before the finish
photocell to guarantee the necessary measurement precision (see also general instructions, par.2.4 Program 3 (Speedmeter) on p.23).

3.1 APPENDIX A: μGRAPH SERIAL FRAME
(8 BIT, 1 STOP, PARITY NONE)
The serial velocity and the type of protocol used by the displayboard must be set with the Dip­Switch on the control panel. The data transmitted consists of 8 bits of information and 1 bit of Stop, without parity check. There is no hand-shaking. The μGRAPH protocol is based on 2 standard records:
• textual, which allows the display of simple strings of text
• graphic, which allows the display of strings of text and images
3.1.1 Text Frame
When textual records are used, the μGRAPH displayboard is divided up into a number of sections depending on the height of character employed. The textual record will be fully compatible with that of the μTAB alphanumeric displayboard.
The character used by the displayboard can be set manually by means of the Setup of program 0
(see
Program 0 (Normal) on p.19), or the appropriate serial command.
3 character heights can be used, and the display area of each μGraph will be divided up like this:
LINE A
LINE A
LINE B
μGRAPH Displayboard User Manual 40
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
LINE A
LINE B
LINE C
As can be seen, when the HUGE character height is used, μGRAPH has a single line of display. If the MEDIUM character is used, the displayboard is divided into two parts (line A and line B). Finally, if the SMALL character is used, the displayboard is divided into 3 sections (line A, line B e line C). It should be pointed out that when two or more μGRAPHs are connected in series, there is no break between one displayboard and the next, but, for example, when 3 μGRAPHs are used in series, strings up to a length of 270 pixels can be shown, compared with 90 for the single displayboard. As well as height, another important characteristic of the fonts is width. Some fonts can be shown
in both proportional and non-proportional mode (see chap.
Proportional and Non-Proportional
Fonts
on p. 48).

3.1.2 Proportional and Non-Proportional Fonts
In both textual and graphic frames, some fonts can be displayed in non-proportional and proportional mode:
• non-proportional fonts have letters, figures, punctuation and spaces of the same width
• proportional fonts have: -figures of the same width
-punctuation of the same width (less than that of the figures)
-letters of variable width
-space the same width as for figures
-“short” space the same width as for punctuation and corresponding to the character ASCII 255
Font
Non-Proportional
Font
Proportional
The “brief” space of proportional fonts is very useful when times must be lined up on different lines:
ASCII 32
ASCII 32
ASCII 255
As can be seen in the figure, to line up the time of the bottom line with that of the top line, two “normal” spaces and one “brief” space have been used.

3.1.3 Graphic Frame
The advantage of the graphic frame is that it allows you to display images and active objects as well as text strings. The position of strings and images is not restricted by lines or columns. The positioning of each object will be completely free, will have as reference the upper-left corner of the μGraph and be given in pixel. The objects themselves will have their highest point on the left as reference (unless a different setting is made). To use the displayboard in graphic mode, commands must be sent to the identifier (see Address field) ‘@’. The first μGraph will transmit the data to the others. If data is sent to the graphic displayboards with the address ‘A’, ‘B’ and so on, it will be interpreted as μTAB commands and treated as such. The format of the command frame is different for commands sent to the graphic displayboard, so it is important not to get the identifiers mixed up. At the start of the Data area 2 words are inserted with the coordinates in pixels of the starting point of the command and a byte containing the Binary Operation to be made. If a position parameter is used in the command for μTab, this will not be transferred but will be replaced by the new format.
NOTE: The Binary Operator value will not in fact be used for all commands (for example, for the
PAUSE command). However, it must be sent for all graphic displayboard commands.

3.1.3.1 Graphic Frame format and Command table
The format of the frame for the graphic displayboard will therefore become:
Field Length Content Meaning
Start of Frame 1 ESC
(0x1B)
Start of command
Address 1 @ (0x40) Identifier of Graphic Displayboard Command 1 Variable Command to be sent to Displayboard Start of Horizontal Coordinate
2 0-809 max 9 displayboards placed side by side (the first
column is the one furthest to the left) Start of Vertical Coordinate
2 0-383 max 16 placed one on top of the other (the first line
is the top one) Binary Operation 1 0-4 See relative table below
Font 1 0-3 Binary code
0=Default

2=12xVariable proportional (MEDIUM)
3=24xVariable proportional (HUGE)
4=24x15 'full size', only numeric (SPECIAL)
5=12x10 non proportional (MEDIUM FIXED)
6=24x13 'full size narrow', only num. (SPECIAL2)
Note: by adding 128 (0x80) to the font identifier,
alignment to the right is activated. In this case the
start position is in relation to the top right corner of
the field. Data Variable Variable Command optional data area End of Frame 1 ETX
(0x03)
End of Command
Checksum 1 Variable 7-bit checksum made on whole frame.
The table below gives the identifiers of the binary operator applied. ‘Source’ means the bitmap transferred with the command, and ‘destination’ the area of the displayboard on which it is placed.
Code Operation performed
0 No Operation: Copies the pixels, writing over the previous status 1 NOT: Inverts the source values and copies them on the destination 2 AND: Only the active pixels on both the source and destination stay switched on 3 OR: Only the switched-off pixels on both the source and destination are
switched off
4 XOR: The pixel at destination is inverted if the corresponding pixel at source is
switched on.
NOTE: by adding 128 (80 hex) to the Binary Operator, the command will be regularly processed, but the displayboard will not be updated. This allows to send several commands (e.g. several
strings placed at different positions), updating the visualization just when the last command is received.

3.1.3.2 Active Objects
The display commands include “Active Objects”, that is, predefined objects which are managed autonomously by the graphic displayboard. Active objects can be of 4 different types:
• The internal time of the displayboard (Real Time Clock) in various formats: it is provided by the internal quartz clock of the displayboard, which functions also when power is off. It is usually synchronized to the time of day.
• The time of day in various formats: it is provided by the quartz precision clock of the displayboard which functions only when power is on. When switched on, it synchronizes itself with RTC
• Data in various formats
• Rolling texts
On every μGRAPH displayboard up to a maximum of 16 active objects can be displayed, each of which is characterized by an origin (coordinates x and y of the start pixel). If two active objects have the same origin, they can only be displayed one at a time. The command for displaying active objects requires the use of a special “Graphic Header” (ESC ­@ - command – x_start – y_start – binary operator – font).
