1 Introduction
The motherboards for PCAN-MicroMod provide an application-
oriented environment. Typical characteristics of this product group
include a wide supply voltage range and the protective circuit for
the inputs and outputs. CANopen® firmware is available for all
PCAN-MicroMod motherboards.
The Mix 1 motherboard serves common analog and digital require-
ments and supports temperature measurement.
Note: This manual only refers to the motherboard as base for a
PCAN-MicroMod and to the standard firmware. For the PCAN-
MicroMod and the configuration program PCAN-MicroMod
Configuration, there is separate documentation.

2 Hardware Configuration
You can customize the motherboard by modifying the hardware.
The following subsections contain descriptions about possible
modifications.
Accessing the Motherboard
In order to carry out the modifications described in the following
sections, unscrew the lid of the casing and pull off the MicroMod
from the motherboard.
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the motherboard or the PCAN-MicroMod. Take
precautions to avoid ESD when handling the boards.
Remounting the MicroMod
When you remount the MicroMod, take notice of the white triangu-
lar marks on each the motherboard and the MicroMod (upper left
corner). These marks must align.

2.1 Modification on Nominal Supply
Voltages > 12 V
If you want to supply the Mix 1 motherboard with a nominal voltage
+Ub> 12 V (usually 24 V), then you must do the following
modification:
1. Equip the unpopulated position D6 with a reference diode
BZV55C12 (package SOD-80).
Figure 2: Position D6 (top side of the PCB)
2. Replace the 0-Ohm resistor on position R33 with a resistor of
1.6 k(package S1206).

Note: You do not need to consider voltage fluctuations that
might occur. A modification isn't required in that case. Exam-
ple: In the automotive sector up to 18 V may occur at a nominal
voltage of 12 V.
2.2 Pull-up/Pull-down Circuits for the
Digital Inputs
At delivery the digital inputs are set to pull-up circuits. You can set
them to pull-down circuit in groups. This is done by repositioning
resistors.
Digital inputs Pull-up (+Ub)*Pull-down (GND)
DIn 0 R31 (2.7 k) R12 (2.7 k)
DIn 1 and DIn 2 R53 (0 ) R55 (0 )
DIn 3 to DIn 5 R54 (0 ) R56 (0 )

Attention! Double-check for inadvertent short circuits after
altering the setup, especially at positions R53/R55 and R54/R56.

2.3 Measuring Range Extension of the
Analog Inputs
You can extend the measuring range of each analog input to a
higher maximum voltage than 5 Volts by using a voltage divider. On
delivery of the motherboard the resistor positions R30 and R43 on
the bottom side of the PCB are not equipped. By inserting a resistor
Rx(package S0805) with a value calculated with the following for-
mula the measuring range is extended to the desired maximum
voltage UMB.

3.2 Configuration Program
In order to create and transfer MicroMod configurations the Win-
dows software PCAN-MicroMod Configuration is used. This section
covers basic points about installation and use of the program with
the Mix 1 motherboard.
You'll find detailed information about the use of PCAN-MicroMod
Configuration in the related documentation which is invoked via the
program (e.g. with F1).
3.2.1 System Prerequisites
Windows 10, 8.1, 7 (32-bit or 64-bit)
Computer with CAN interface of the PCAN series (for transfer-
ring a configuration to the PCAN-MicroMod via CAN)

3.2.2 Installing the Program
Under Windows install the program from the supplied CD. Start the
corresponding installation routine by using the CD navigation going
to Tools > PCAN-MicroMod Configuration 2.5.x.
3.2.3 Creating a Configuration
When you start creating a new configuration in PCAN-MicroMod
Configuration, the Board Type dialog box appears in order to select
the type of the used motherboard. The necessary settings are
explained in the following.
Figure 8: PCAN-MicroMod Configuration: selection of the Mix 1 motherboard
Board Type: PCAN-MicroMod Mix 1
Module No: 0
The module number of the MicroMod on the Mix 1 motherboard is
set to 0 at delivery and is relevant if you want to configure more
than one MicroMod on the same CAN bus. See also section 3.4
Several MicroMods on the CAN Bus on page 16.

Bitrate MicroMod: 500 kbit/s
At delivery the MicroMod is set to a bit rate of 500 kbit/s. A change
of this setting will take effect after sending the completed configura-
tion to the MicroMod.
Note: For the first transfer of a configuration to the module it
must be integrated in a CAN network with a bit rate of
500 kbit/s.
3.2.4 Applicable MicroMod Services
The motherboard's inputs and outputs are controlled by the servi-
ces of the MicroMod. The following table shows the assignment of
the motherboard functions to the MicroMod services.

3.3 Status LEDs
The motherboard including the MicroMod has three LEDs with the
following status indications:
LED Indication
Power (green) Power is applied.
DOut 7 (red) Is linked to the digital output DO 7 of the MicroMod and
can be configured freely.
Activity (red) Status of the PCAN-MicroMod:
blinking at 1 Hz normal operation
blinking at 2 Hz invalid or no configuration
blinking at 5 Hz configuration mode
continuously on internal MicroMod error
3.4 Several MicroMods on the CAN Bus
If you want to use several MicroMods on the same CAN bus and
want to configure them, each one needs its own module number.
That way the MicroMods are distinguishable for the program PCAN-
MicroMod Configuration.
The module number is set on the MicroMod by solder jumpers and
lies in the range of 0 to 31. At delivery each MicroMod has the
module number 0.
During normal operation of the PCAN-MicroMod, the module
number has no effect on the CAN communication.
For setting the solder jumpers on the MicroMod unscrew the top of
the casing and remove the MicroMod from the motherboard. Please
find further information about the assignment of module numbers
in the separate manual for the PCAN-MicroMod.

components on the motherboard or the PCAN-MicroMod. Take
precautions to avoid ESD when handling the boards.
Remounting the MicroMod
When you remount the MicroMod, take notice of the white triangu-
lar marks on each the motherboard and the MicroMod (upper left
corner). These marks must align.
