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 2 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 Pull-up/Pull-down Circuits for the
Digital Inputs
At delivery the digital inputs are set to pull-up circuits. You can set
them together to pull-down circuit. This is done by repositioning a
0-Ohm resistor.
Digital inputs Pull-up (+Ub)*Pull-down (GND)
DI 0 and DI 1 R73 (0 ) R74 (0 )

Attention! Double-check for an inadvertent short circuit after
altering the setup.

2.2 Measuring Range Extension of the
Analog Inputs
You can extend the measuring range of each analog input to a
higher maximum voltage than 4.1 Volts by using a voltage divider.
On delivery of the motherboard the resistor positions R28 to R30 on
the bottom side of the PCB are not equipped. By inserting a resistor
Rxwith a value calculated with the following formula the measuring
range is extended to the desired maximum voltage UMB.

2.3 Using a PT1000 with Three-Wire
Connection
At delivery the Mix 2 motherboard is configured to be used with a
PT1000 thermistor with two-wire connection. If you would like to
use a PT1000 with three-wire connection instead (e.g. in case of a
long connection cable), you must remove the 0-Ohm resistor on the
PCB located on position R76.
