1 General
The large display numeric LED can be used universally for displaying
production data, or as an information board.
The modular design allows for cost-effective models of various sizes,
and with different character heights and numbers of digits.
Thus integration into existing equipment or systems is easy and simple.
Display Functions
Data transmission: InterBus
Simple parameter setting and initial start-up
Variable size thanks to modular display design.
Important Note:
As of 11/09/2005 a new, simpler frame type is adjusted at the delivery by de-
fault (see chapter “Standard Transmission Frame“).

3.3 Device or System Start-Up
The large format numeric LED display performs internal memory and
function tests while powering up.
Start-Up Procedure:
Segment test
After this, the display waits for valid user data.
If a valid frame is sent during the test routine, the test will complete and
after that, data are displayed.

3.4 Control via the InterBus Interface
Data received by the InterBus („out“ words) are stored to intermediate
memory, processed and transmitted to the large format display. After
the frame has been transmitted, the frame data are mirrored via the In-
terBus as a response („in“ words).

3.4.1 User Data –IB Output
The large format alphanumeric display utilises 4 IB output words. These
are used for transmission of user data which are required for control of
the large format display.
3.4.2 User Data –IB Input
The large format numeric display utilises 4 IB input words. These are
used as a response to user data which have been transmitted to the
large format display. After transmission of each frame, the IB data which
have just been transferred to the large format LED display are mirrored
in response to the „in“ words.

Toggle byte
The interface at the large format display is driven with the first byte of
output data (toggle byte TB).
The toggle byte is saved to intermediate memory immediately after the
InterBus interface has been initialised (first of all it must be „0“), and is
then always compared with the respectively current content of the first
byte of output data. As soon as it’s value is changed, subsequent output
data are evaluated and interface data are transmitted to the large format
display if appropriate. The only evaluation criterion is a change of con-
tent –the actual content itself is irrelevant.
The following must be observed in order to transmit a frame to the large
format display:
The frame at the large format LED display is subdivided into blocks of
7 bytes each, which are transmitted one after the other.
The InterBus interface accepts output data transmitted by the IB
master (7 bytes) as soon as the toggle byte has been changed. As
soon as transmission of the 7 bytes of frame data to the large format
display is concluded, the output data transmitted by the IB master are
mirrored to the input data at the IB master (8 bytes).
The next block cannot be transmitted until input and output data are
identical (the comparison of the toggle byte is sufficiently).
If the last block of the protocol requires less than 7 bytes, the unused
bytes must be set to 00h (they are not sent).

5.1 Maintenance and Care
Please observe the following instructions.
Make sure that the housing can be opened for adjustment and
maintenance even after the display has been installed. Allow for ad-
equate clearance at the back, front and top of the display unit in or-
der to follow for sufficient ventilation (if vent slots are included).
Display quality is impaired by direct illumination with bright light
sources and/or direct sunlight.
The display must be switched off before cleaning.
Protect the display from excessive humidity, extreme vibration, di-
rect sunlight and extreme temperatures. Non-observance may lead
to malfunctioning or destruction of the device. Under certain cir-
cumstances electrical shock, fire and explosion may occur as well.
Information concerning allowable ambient conditions, including rec-
ommended temperature ranges, can be found in the chapter enti-
tled „Technical Data“.
The display may not be placed into service if the device and/or the
power cable are known to be damaged.
Do not attempt to repair the device yourself. The guarantee is ren-
dered null and void if the device is tampered with by unauthorised
persons.

5.3 Warranty / Liability
For the product, liability is assumed for defects, which existed at the de-
livery date according to our General Terms and Conditions.
Technically changes as well as errors are excepted. A claim for delivery
of a new product does not exist. The buyer has to check the received
product immediately and indicate evident defects at the latest 24 hours
after detection. Non-observance of notification requirements is equated
with acceptance of the defect. Not immediately visible defects have to
be indicated immediately after their perception too.
Generally, defects and their symptoms must be described as accurately
as possible in order to allow for reproducibility and elimination. The buy-
er must provide for access to the relevant device and all required and/or
useful information at no charge and must make all of the required data
and machine time available free of charge.
The guarantee does not cover defects, which result from non-
observance of the prescribed conditions of use, or from improper han-
dling.
If the device has been placed at the disposal of the buyer for test pur-
poses and has been purchased subsequent to such testing, both parties
agree that the product is to be considered “used” and that it has been
purchased “as is”. No guarantee claims may be made in such cases.
The General Terms and Conditions of microSYST Systemelectronic
GmbH in current version apply as well.
