USB-2-X

2 Features

The USB-2-X device is an interface converter which is equipped with a CAN interface, an IIC interface, a LIN interface, an SPI interface and an RS485 interface. It can be connected to the PC via the USB interface.

The USB-2-X device is mainly designed for use with some of the TRINAMIC evaluation kits, but it can also be used in any other purpose where a connection between a PC and a CAN interface, an IIC interface, a LIN interface, an SPI interface or an RS485 interface is needed.

Its frame is a compact, metalized standard housing (known as 25 pin Sub-D adapter housing) with the dimensions 53mm x 55mm x 16mm (length x width x height). Please notice that plugs and cables need further space.

The software supplied with this product can be used with every version of the Windows operating system that supports USB (Windows 98, Windows ME, Windows 2000, Windows XP and Windows Vista). Windows 95 and Windows NT4.0 do not support USB, so the USB-2-X device cannot be used with such systems.

4.2.1 CAN connector

Table 4.1: CAN connector

 A CAN termination resistor of 120 ohms can be activated shorting the two pin header placed below

the USB connector using a jumper.

4.2.2 LIN, IIC, and SPI connectors

Table 4.2: LIN, IIC, and SPI connectors

 When LIN is used, the LIN transceiver of the USB-2-X device has to be powered by the target via pin

9 of the connector.

 The pin assignment has been selected in order to allow direct connection to the TRINAMIC TMC211

evaluation board and the TRINAMIC TMC222 evaluation board.

 Please note that the additional SR (slave request) line of the SPI interface is not available on this

connector but on a board edge solder pad (the second of eight solder pads counted starting from IC labeled 75176).

 The IIC interface and the SPI interface cannot be used simultaneously.  Also, the LIN interface and the RS485 interface cannot be used simultaneously.

5 Putting the USB-2-X into operation

5.1 Starting up

1) As USB devices are hot pluggable it is not necessary to turn off the PC when plugging in or

removing the USB-2-X device. Just plug in the device when the PC is switched on and Windows is running.

2) When you plug in the USB-2-X device for the first time you will be prompted for a suitable device

driver after a few seconds. You will have to be logged in as administrator to be able to install device drivers on Windows 2000 or Windows XP.

3) Insert the TMC TechLib CD that is supplied with this product and select the USB2X.INF file in the

interfaces\USB2X directory on the TechLib CD.

4) The device driver will be installed. Now the USB-2-X device can be used.

5.2 Software

5.2.1 The USB-2-X with a TMC211 evaluation board

If you are using the USB-2-X device with a TMC211 evaluation board, use the software that is supplied with the evaluation board: Eval211USB.exe. This software is described in the manual of the TMC211 evaluation board.

5.2.2 The USB-2-X with a TMC222 evaluation board

If you are using the USB-2-X device with a TMC222 evaluation board, use the software that is supplied with the TMC222 evaluation board: Eval222USB.exe. It is described in the manual that comes with the TMC222 evaluation board.

5.2.3 The USB-2-X.EXE software for any other application

With this software you can send and receive any data using the interfaces of the USB-2-X device.

Start up as follows:

1) Start the program by double clicking the file USB2X.EXE which is supplied in the interfaces\USB2X

directory of the TechLib CD.

2) The main window appears. Select your USB-2-X device in the interface section.

3) Click the Open button.

4) After the connection to the device has been successfully established, the firmware revision number

of the device is shown.

5.2.4 Further information about the software

On the IIC, LIN, CAN, SPI and RS485 tab pages you can find all functions to make use of the interfaces of the USB-2-X device. Please check TRINAMIC’s web site from time to time and watch out for updates (of the PC software and the firmware).

Notes on using the USB-2-X device in your own PC software can be found in the documentation of the USB2-X host interface protocol. There is also an example program, written in Delphi.

In the near future there will also be a DLL that will make integrating the USB-2-X device into your own devices very easy. Please check TRINAMIC’s web site from time to time if it is already available.

Additional support tools for the USB-2-X are also available. Please check our website www.TRINAMIC.com to find the temperature logger to measure 8 temperatures via IIC with a LM75 chip or a chip programmer to read out and write via SPI, IIC or micro wire to EEPROMS and SPI chips like the TMC428.

6 Updating the firmware

The USB2X.EXE software also makes it possible to update the firmware of the USB-2-X device via its USB interface. Firmware files for the USB-2-X device can be downloaded on TRINAMIC’s website (www.TRINAMIC.com).

For installing a new firmware file, please follow the instructions:

1) Download the file from TRINAMIC’s web site. Firmware files for the USB-2-X device normally have

the extension .s19.

2) Start the USB-2-X PC software and click the Open button.

3) Click the Firmware update button. A new window appears.

4) Click the Load button and select your new firmware file.

5) Click the Start button and wait for the update process to complete.

6) Try if the USB-2-X device still works.

If this should not be the case, quit the USB-2-X software, pull out the USB plug on the USB-2-X device, wait some seconds and plug it in again. Now restart the USB-2-X software and try again. If for some reason the USB-2-X device should still refuse to work, try to update the firmware again.
