Connecting your PC with the central unit

For sending/receiving from PROSOFT to the DOIP central unit, there are two possible ways:

  1. USB Connection (Short cable; temporary use). With a USB cable (standard USB-B to USB-A, not included with the central unit) you can connect the DOIP directly to the PC with USB 2.0 and USB1.1 compatible ports. This is typically used for temporary connections (communication with PROSOFT and testing I/O's). Remember that USB is not able to use long cables (about 5 meters).
  2. Ethernet Connection (Long cables possible – up to 100 meter; temporary or permanent connection). Through the RJ45-Ethernet connector on the DOIP central unit you can connect to your LAN (Local Area Network). This is typically used for a permanent connection with a PC, GUI-Device (touchscreen PC) or any LAN application.

Before you start:

Windows 7, XP and Vista:

This guide to communicate with the DOIP central unit is written for Windows 7. For Windows XP/Vista the procedures are largely the same. Where needed, there will be extra screen shots/Information for Windows Vista/XP.

Control Panel:

For some parts in the guide you will be asked to go to the control panel. We assume that the control panel is set to the 'Classic view'. In Windows 7 you find this in the right upper corner of the control panel. In both Vista and XP you can find button 'Classic view on the left part of the control panel'. If the button is labelled 'Switch to category view' you are already working in the classic view.

USB Communication

To avoid possible problems it is recommended always to use the same USB-port on your PC. Some PC's tend not to recognize the DOIP central unit if connected to another port!

USB is the easiest way to connect your PC to the DOIP central unit. To be able to use this way of communication, a specific USB driver should be installed first. Follow the steps below to prepare your PC:

Installing the necessary USB driver (Windows 7)

  • Make sure that the correct PROSOFT Suite version is installed on your PC.
  • Connect your PC to the DOIP central unit using a standard (A to B type) USB cable
  • Windows will give a short message that the hardware couldn't be installed.

Image208

  • Go to the Control panel
  • Click on Device Manager
  • Look for the RNDIS/Ethernet Gadget (has a yellow triangle)
  • Click with the right mouse button on this item and choose update driver software.

Image209

  • Select in the next screen:' Browse my computer for driver software'

Image211 .

  • Select in the next screen: ’Let me pick from a list of device drivers on my computer'.

Image213

  • Select in the next screen: Have disk'.

Image215

  • Now browse to the installation folder of PROSOFT. Normally this should be c:\Program Files (x86)\TELETASK\PROSOFT 3.2 and click ‘OK’.

Image217

  • Windows will give a warning about the installation of the driver, click 'Continue anyway'
  • Windows will now install the correct driver for the DOIP central unit (this may take some time)
  • Click Finish in the last screen of the 'Find New Hardware Wizard'.
  • Your computer is now ready for communication with the DOIP.

Image218

Drivers are installed for each USB port separately, so if you use another USB port of your PC (notebook) the next time you want to communicate with the DOIP you will need to repeat this procedure.

Installing the necessary USB driver (Windows XP)

  • Make sure that the correct PROSOFT Suite Version is installed on your PC.
  • Connect your PC with the DOIP Central Unit by a standard (A to B type) cable.
  • Windows will automatically start the 'New Hardware Wizard'.
  • Choose 'Not this time' and click on next.

Image220

  • Choose 'Install from a list or specific location (Advanced)' and click next

Image221

  • In the next screen, select 'Search for the best driver in these locations'

check 'Include this location in the search', click the browse button and select the location of the PROSOFT Installation folder.

  • Windows will give a warning about the installation of the driver, click 'Continue anyway'

Image222

  • Windows will now install the correct driver for the DOIP central unit (this may take some time)
  • Click Finish in the last screen of the 'Find New Hardware Wizard'.

Image223

  • Your computer is now ready for communication with the DOIP.
Drivers are installed for each USB port separately, so if you use another USB port of your PC (notebook) the next time you want to communicate with the DOIP you will need to repeat this procedure.

Checking the connection

You can check if the USB cable is correctly connected to the TELETASK Central unit:

  • Go to Start, Control Panel, Network and sharing centre, Manage network connections (in the bar on the left, 'Change Adapter Settings). For XP is this Control Panel, Network connections.
  • There must be a connection with Device Name; TELETASK Central Unit (RNDIS)...

Image224
Troubleshooting: If you have problem communicating with the DOIP via USB you can check the following

Check if the USB port is working properly with another device (e.g. mouse, keyboard,)
Check if you can communicate via USB to another DOIP central unit (if available), if this works, there might be a problem with the central unit, contact your TELETASK supplier.
Make sure your Windows is updated (Service Pack 2 is necessary on XP)
Check if it is possible to communicate to the DOIP using another USB port/Computer. If this works there might be a problem with your USB port / computer, contact you PC distributor.

Reinstall the driver

Following section describes how you can install the driver when you cancelled the normal procedure.

  • Make sure your PC is (still) connected to the DOIP with USB
  • Go to Device Manager (Start/Control Panel)
  • Probably you will find a device there with an exclamation mark

(this means: not correctly installed)

  • Right click on that item en choose 'uninstall'
  • Press OK to confirm the removal of the driver.
  • Remove the USB cable from the PC
  • Now you can go back to section A. Installing the driver

Ethernet Communication

Ethernet communication looks is a bit more complex than USB communication. In most cases however setting up the Ethernet communication is as easy (or even easier) as setting up a USB connection. This is the case when you have a simple LAN network to which your computer is already connected.
You can connect the DOIP to your Network (switch/router) with a standard Ethernet patch cable.
From the moment this cable is connected correctly, the Communication LED (LEDLINK) on the DOIP printed circuit board will be on. If this LED is blinking continuously there is possibly something wrong whit the cable (The LED will blink only when there is data-communication)
If your network is a 100Mbit network or more the 100Mb detection LED (LED100MB) will be lit as well.

Ethernet communicatie through LAN

The best way to connect a PC to the Central Unit through Ethernet is by using a hub, switch or router. Most likely you already have a local network conencted to your PC. Connect the DoIP, and if necessary your computer to the LAN. In order to establish a communication between your computer and the Central Unit, follow these steps:

  • Restart the Central Unit once it is connected to the LAN (press the 'Restart' button or remove the power for ten seconds).
  • Start Prosoft SUITE V3.1 (or higher); open the .NBT file you want to use (or create a new one if required.)
  • Go to the menu 'Communication' and select 'Send'.
  • Within the communication window select 'Ethernet'

Image225

  • Click the 'Search button' and a Message box will appear asking you to press 'SW2' on the central unit. (The 'SW2' button on the DOIP is located at the right side of the printed circuit board, above the battery. Press and release, this button.)
  • To make sure that this functionality works your FIREWALL must allow that PROSOFT can accept connections from the network, if you use 'Windows Firewall' you will automatically get a 'Security Alert', you have to choose 'Unblock' there. If you use another Firewall on your PC (ex. Norton Internet Security) please look at the documentation of that software what to do (you can also temporary disable the Firewall)

Image226

  • A new window will appear in PROSOFT in which you can set the communication parameters. In most cases, the new window will look like this:

Image228

  • The text on the top describes the IP settings as they are at the moment, at the bottom you can change the settings. For a new DOIP (or a DOIP on which the IP-address is dynamically assigned) PROSOFT will make a proposal for new settings. It is advised to accept the settings PROSOFT suggests.

There are two types of assigning an IP address: Dynamic or Static. With Dynamic the TELETASK central unit will ask for an IP address on the network, the switch or router will provide the IP address automatically. With a Static IP address the central unit will always have the same IP address.
New DOIP central units always use 'Dynamic' so that they receive all necessary information (IP address, Subnet Mask, Gateway and Name Server) from the network. The disadvantage of this system is that the IP-address can change. Therefore it is advisable to change it to a 'Static' IP-address, like PROSOFT suggest. In this way the IP-address of the central unit will not change, which is easier for sending, necessary for connecting GUI's, ..

  • If needed make changes to the settings, and click save to apply. (You can always return to this screen to change the settings again).
  • The IP information is now inserted in your .nbt file (save the file to keep the settings for further usage).
  • Your PC is now ready for communication with the DOIP (using the saved .nbt file)
  • In the communication screen of PROSOFT you can now connect to your central unit.
Remark: when you are connected to the central unit, the 'Search' button, changes to a 'Configure' button. When you click this button you immediately get the IP configuration screen, and you can change your settings (if this is needed).

Trouble shooting: It is possible that procedure above will not work, this is the case if:

The central unit is 'Static' set to an IP address in another network range than the range of the LAN network. For most small networks IP addresses are in a different range when the first three numbers are not the same (e.g. 192.168.0.10 and 192.168.0.11 are in the same range, 192.168.0.10 and 192.168.1.11 are not).
There is no DHCP server on the LAN (the DHCP server is responsible for giving IP addresses to devices that ask for it, in most cases the Switch or router is also the DHCP server.). In this case the DOIP will use the default IP address (192.168.0.200) and it is possible that this IP address is in wrong network range for your LAN
The range 192.168.168.XXX should not be used (This range is reserved for USB communication). All other ranges are free to use
It is not possible to connect devices in a different IP range, so in both these cases you cannot configure your central unit using Ethernet, use USB to set the IP settings of the central unit to 'Dynamic', reset the central unit and restart this procedure.
Alternatively you can push in SW1 and SW2 during 10 second. Herewith the Ethernet settings of the DOIP central unit are brought back to factory settings (DHCP).
PAY ATTENTION: it will also delete possible NBT information from the DOIP Central Unit.
WARNING: In this procedure we will change the IP configuration of your computer. So it is possible that your computer will no longer be able to connect to your network or Internet (you will need to set your PC settings back to what they were before you started this procedure in order to be able to connect again).

TELETASK does not advise this procedure, we recommend using USB or Ethernet using a LAN connection. However there can be situations where this procedure is needed to communicate with the central unit (e.g. if there is no LAN, and you do not have a USB cable with you).
The connection between the PC and the DOIP is normally done with a 'crossed CAT5' cable. (Most recent network-cards of the PC's have an 'auto-cross/straight' detection, then you can also use a straight patch cable)
The steps to set up a connection are:

  • Find the IP-Address of your central unit
  • Give the PC to an appropriate IP address

Find the IP Address of your central unit

The default IP-Address of a new DOIP is 192.168.0.200. If you just unpacked your DOIP you can skip this section

  • Connect the central unit and your PC
  • Open TELETASK PROSOFT Suite software, go to the communication screen, click on the search button and press 'SW2' on the TELETASK central unit

(see Ethernet communication using LAN for a more detailed description of this step).

  • There are two different possibilities of the result by pressing the SW2 switch

1. You get the IP configuration box:
Image229

  • Press 'Cancel'
  • The IP Address is automatically filled in
  • You can now press 'Connect' and then press 'Transmit' to send your PROSOFT file
  • You can skip the rest of this document

2. You are in the wrong IP subnet:

  • PROSOFT Suite gives a message that it can't be connected with the Central Unit.
  • Press 'OK'
  • The IP Address is automatically filled in
  • Note this IP address of the central unit
  • Close the PROSOFT Suite

Give the PC an appropriate IP address (Windows 7).

  • Go to Start, Control panel, Network and sharing- change adapter settings). You will have a window looking like this:

Image230

  • There might be more than one connection (Wireless connection, 1394 Connection,); you need to find the normal wired connection (not the wireless, nor the 1394 connection).
  • 'Right click' on the Local area connection and choose properties
  • In the new window, select 'Internet Protocol (TCP/IP)' Version 4 connection in the list and click 'Properties'.

Image231

  • Now you will get a window where you can set the IP configuration for your computer. Change the settings so it looks like this (Assuming that the IP address of the Micros is 192.168.0.200. If not, make sure that the 3 first numbers are the same as from the IP address of the DOIP and that the last number is different).
Warning: Note the settings. Before changing them you might need them in order to reconnect your computer to a network or Internet afterwards.

Image232

  • Click OK to save the new settings. Wait until MSWindows has applied the new settings (this may take some time).
  • Open PROSOFT Suite, go to the communication screen, enter the IP address of the DOIP and click 'Connect'.
  • Now you can press 'Transmit' to send your PROSOFT file to the DOIP central unit.

Give the PC an appropriate IP address (Windows XP)

  • Go to Start, Control panel, Network connections. You will have a window looking like this:

Image233

  • There might be more than one connection (Wireless connection, 1394 Connection,); you need to find the normal wired connection (not the wireless, nor the 1394 connection).
  • 'Right click' on the Local area connection and choose properties
  • In the new window, select 'Internet Protocol (TCP/IP)' connection in the list and click 'Properties'.

Image234

  • Now you will get a window where you can set the IP configuration for your computer. Change the settings so it looks like this (Assuming that the IP address of the Micros is 192.168.0.200. If not, make sure that the 3 first numbers are the same as from the IP address of the DOIP and that the last number is different).

Warning: Note the settings. Before changing them you might need them in order to reconnect your computer to a network or Internet afterwards.
