Description and scope of delivery
Thank you for purchasing your MCE18. With the CANchecked Multifunction Can Bus Extension, you
can feed additional sensors to your Can Bus and thus serve as an Input/Output Expander. The MCE18
does not have an internal mapper and places the measured sensor voltages directly on the data bus.
This manual applies equally to its sister product, the CFE18.
There are three versions of the MCE18, some of which differ in terms of functionality and pinout. The
safest way to find out which version you own is to take a look at the revision number on the back of
the board. To do this, loosen the four screws that hold the back plate, then remove the board and
read the revision on it.
In Chapters 2 you will find the assignment of the revision number to the variant of the MCE18. For
version 3 devices, this is engraved on the case (V3).
This guide explains how to operate and handle your MCE18. In addition to connecting and updating,
this guide also covers the connection and operation of our "Device Setup Software" (
DSS).
In the box you will not only find the MCE18, but also the following items are included:
•
The Quickstart Guide
•
one AMP Superseal connector (TE 4-1437290-0)
•
36x AMP Superseal pins for self-crimping 1.0 20AWG (TE 3-1447221-4)
•
Three 2.54 mm
jumpers
Your MCE18 itself has a status LED, an AMP Superseal connector and a MicroUSB port on the board
(version 3). This is not accessible without disassembling the unit and usually does not have to be used
by the customer. The MicroUSB on the board is redundant to the USB pinout of the AMP connector,
which all versions have.
The digital inputs can optionally be equipped with an internal pull-up resistor (20-50 kOhm). The
setting is done in the DSS. You can find more information about this in chapters 4.
On the back of the board you can attach three jumpers (by default they are not mounted).
Jumper 1: Can Bus Termination 120 Ohm (all versions)
Jumper 2: AIN 1 (all versions), AIN 2 (V1 and V2 only) 1 kOhm
Jumper 3 AIN 6 (all versions), AIN 7 (V1 and V2 only) 1 kOhm
Terms associated with the MCE18 are shown in italics in this guide for better understanding.
