Magellan Motion Processer Developer’s Kit Manual
A
The L-bracket is optional but highly recommended because it provides a stable mechanical base from which you can
connect and operate your prototype system. With the vertical plate option installed the Atlas units have additional heat
sinking, which can be extended further by connecting the vertical plate to your own heat sink or cold plate.
A.2
Installation and Getting Started
In these instructions it is assumed that you have purchased a Magellan DK (Developer’s Kit), which comes with the
Pro-Motion exerciser and tuning software. If you have not purchased a Magellan DK then you will still find these
instructions useful, however you will use the detailed connections detailed in
Section A.3, “Atlas Carrier Card
to connect your system and begin operation.
A.2.1
Setting Atlas SPI Bus Addresses
If your Atlas DK came with an L-bracket, the Atlas units are pre-loaded on the L-bracket hardware and each Atlas is
pre-addressed with axis number labeled. You can therefore skip to
Section A.2.2, “SPI Bus Connections”
getting started instructions.
If you are not using an L-bracket, you will need to set the SPI bus address using jumper J6 on each Atlas carrier card.
For vertical Atlas units you can set the jumper without removing the Atlas from the carrier card. For horizontal Atlas
units you must remove Atlas from the socket, select a jumper, and then carefully remount the Atlas into the socket.
to select an address.

SPI Bus Connections
If you are using an L-bracket you should plug in the provided 12" DB9 cable at J5, the female DB9 connection of the
carrier card. Do not plug in at the male DB9 connection, J4. Doing so will mean that you will not be able to connect
your Atlas units to the Magellan DK card. Once you have plugged in the DB9 cable, you can skip forward to
If you did not order an L-bracket, you will need to first connect the Atlas units together, and then connect the provided
12" cable.
Each Atlas must have a unique address from 1 to 4, and this number directly corresponds to the axis number
addressed by the Magellan Motion Processor
.
The DB9 connections used with the Atlas DK are not compatible with standard RS-232 serial ports. Do not at-
tempt to plug this connector directly into your PC.
