Device Configuration
• Wire the inputs and outputs according to the connection diagram.
• If required, set the baud rate (see page 9).
• Set the device address (in a network, make sure that the connected devices have different
addresses).
• Check whether the device is ready for operation: RUN LED is on, FA LED is off.
• Wire the interface or the network.
• Check for proper functioning of the serial communication.
• Configure the device or the network and set the necessary parameters.
Communication Parameters
The following tasks are based on serial communication:
• Setting the parameters using software
• Loading the firmware
• Setting the connections in the network
To make sure that these tasks can rely on smooth data transmission between the PC Software
Tool and the infobox connect device, the characteristics of the communication interface must be
set up correctly.

• Setting the Device Parameters
Use the two hexadecimally coded switches at the rear of the device to set the principal device
parameters . The boot loading function can also be triggered by a switch.
Baud Rates and Addresses
To achieve best communication through the device interface, you can adjust the baud rate so
that it matches the baud rate of the partner device. However, correct and safe data trans-
mission at baud rates higher than the default rate cannot be guaranteed. We therefore
recommend not to change the baud rate of the device.
Procedure:
- Switch off the device
- Set the switch for the required baud rate (see further down)
- Switch on device
- Wait for pulse tone of internal horn (This indicates that the baud rate is saved)
- Set the address of the device (red FA LED is on)
- Wait until the FA LED goes off again (valid address range: 1 to 7Fh)
The following baud rates can be set:

• Reset to Factory Settings
If you wish to reset the device software to the original parameters set by the supplier, set the
switch to 00h/80h. This is necessary, for instance, when the device has been loaded with a new
firmware.
The reset affects the following program sections:
- Reset to default mapping (Careful: Mapping parameters that may have been added by the
user will be lost after a reset!)
- Rese to default parameters (Careful: The current parameter record will be overwritten!)
Procedure:
- Switch off the device.
- Set the switch to 00h.
- Switch on the device (intermittent acoustic signal from the internal signal generator)
- Set the switch to 80h (continuous acoustic signal from the internal signal generator)
- Wait until the acoustic signal emitted by the internal signal generator turns from continuous to
intermittent. (The resetting process is completed.)
- Set the device address. (red FA LED lights up)
- Wait until the FA LED extinguishes again (valid address range: 1 to 7Fh)
• Boot Load Function
A special boot load function is available for updating and servicing the device firmware. You
use it to load a new firmware version into the device.
Procedure:
- Switch off the device.
- Connect the device to your computer (depending on the device type: to the RS 232 interface
or to the CAN card of your PC)
- Start the PC Boot Load Tool “Hexapro”.
- Check whether the interface settings of your PC and the infobox device match.
- Set the hexadecimally coded switch to the boot load position: FFh
- Switch on the device.
- In the Hexapro tool, select the Hex program file.
- Start the program transmission in Hexapro. (A flashing FA LED indicates that transmission is
in progress.)
- Wait until the Hexapro tool indicates the end of transmission.
- Reset the device to its original factory settings (see above).
• Software Configuration (Setting the Parameters and Programming)
The device can be easily adjusted to meet different requirements by configuring it and setting a
number of parameters using software. Two PC software programs are available for this
purpose.
- PC-Tool for WIN 95 / WIN 98 / WIN NT for single user systems
- PC-Network Tool for WIN 95 / WIN 98 / WIN NT for CANopen networks

The infobox device has two data areas that are reserved for configuration and parameter data
and for user-specific programming:
1. Default data (factory settings)
2. User data
When the infobox device is delivered, the user data record and the default data record are
identical. The user data record can be modified as follows:
Changes in the device configuration and device parameters (e.g., write and save a parameter
record in the infobox device).
Aread access to the data record of the device always provides you with the contents of the
user data record. You may always return to the default data record by resetting the device to
the original factory settings. The user data record will then be identical again with the default
settings. (Careful: Such a reset will delete your user data!)
It is good practice to save your user data from time to time in the form of a file using the
relevant PC tool. You can always fall back on it if you have reset the infobox device
inadvertently.
Procedure:
• Configuration and parameter data
1. Establish communication between your PC and the infobox device.
2. Start the PC tool for specifying the configuration and parameters.
3. Open the file that contains the user data.
4. Start downloading this file into the infobox device.
5. Wait until the download procedure is completed (progress is indicated by a progress bar;
completion is indicated by an acoustic signal).
• Network configuration data
1. Establish communication between your PC and the infobox device.
2. Start the PC network tool.
3. Open the file that contains the user data.
4. Call “Load configuration.”
5. Save the data (Option: Save all parameters).
6. Start downloading this file into the infobox device.
7. Wait until the download procedure is completed (progress is indicated by a progress bar;
completion is indicated by an acoustic signal).

ME30 infobox connect
infobox connect 13
The scope in which the programmed configuration and parameter data affect the message
inputs varies as follows:
a) Message channel: Configuration and parameters apply to the selected message input only
b) Message group: Configuration and parameters apply to all 8 message inputs of an input
module.
c) All message Configuration and parameters apply to all message inputs of the
channels: infobox device.
• Input Processing
The signal states of the message inputs are read cyclically (minimum signal duration: 5 ms). A
valid input signal is recorded in the event memory. The record contains the signal status and
date and time stamps (resolution: 1 ms).
a) Working Current (N/O) Signal
The message is generated as soon as the normally open contact closes (signalling voltage is
present).
b) Closed Circuit (N/C) Signal:
This is the opposite of the working current principle. In this case, a message is generated when
a normally closed contact opens (there is no signalling voltage).
Function: Polarity of the message inputs
Range of application: Message channel
Default value: N/O signal
Parameter range: -
For each individual message input you can disable message processing by means of an
activation function. Although message processing is inhibited, the signal states of disabled
inputs are still read and recorded in the event memory.
Function: Activation of message inputs
Range of application: Message channel
Default value: Active
Parameter range: -
Signal filtering by means of software settings is available for reducing the effects of contact
chatter. A signal change at the input is only considered as valid if it is still present after the
selected debouncing delay has elapsed. A second signal change that may occur during the
delay period is not recognized as such.
Function: Debouncing delay for message inputs
Range of application: Message group
Default value: 0 ms (no debouncing delay)
Parameter range: 1 to 250 times 5 ms (5 ms to 1250 ms)
The chatter stop function monitors the number of signal changes at a message input. It
prevents the event memory from being filled with invalid information, for instance when an input
contact is defect. The number of signal changes within a selectable monitoring delay is
counted. When the set limit of signal changes is exceeded , the message input is automatically
disabled. It will be enabled again, when the number of signal changes is within the set limits.
The message input is automatically enabled again, when the number of signal changes is
within the set limits.
Function: Chatter monitoring of the message inputs
Range of application: Message group
Default value: Monitoring period 0 ms (not activated)
Number of signal changes: 10
Parameter range: Monitoring period: 1 to 36000 xl 100 ms (100 ms to 60 min)
Number of signal changes: 1 to 250

Message Processing
The infobox device supports message signalling functions acc. to DIN 19235 and ISA for
processing the acquired message input signals. Pressing the message acknowledgement
pushbutton acknowledges both the acoustig signal and the message. This is very useful when
you want to acknowledge the message instantly as there is no need to press the button twice in
order to acknowledge first the horn and then the message.
Default setting: First-up indication by single flashing light
