If all components are placed and soldered on the right position, the powersupply can be connected. Be sure to have checked all the components not only in on the right location, but also in the right position (polarity!). Some checkpoints:
- Are all the IC's (integrated Circuits) placed wit the pin 1 on the right position?
- Did you place all capacitors with the plus on the right side?
- Are all diodes pointing the right direction?

Before connecting the power, I'll advise you to keep the processors (U4 and U5) out of the circuit, untill you checked the powersupply. Connect the power supply of +12V (J1) and 0 (ground) to J2. Look out for the resistor RA. This resistor will get very hot!

Measure the voltage on the location of J4 and J5. 
This should be +5V exactly. If a higher voltage is measured, turn off the power immediately!

Check the little LED's on the Xport. When no ethernet cable is connected, the red LEd should light up blinking every 10-15 seconds. When the ethernet cable is connected, both the led's (the led's do have two colours!) should light up green; one blinking, showing the traffic on the net, the other one continue, telling you the Xport is happy with the connection. Shut down the power for a while. Place both the porcessors U4 and U5 in their socket.
Attention for pin 1!

Turn the power back on.
If you do have an oscilloscope, you can check the signals on pin 3 - pin 7 of U4; you should see a rectangle wave shape with increasing frequency (pin 7 low f - pin 3 high f).Having checked all that, the hardware part of your IpSonLab is working. (back to the top)

The onboard server can be configured with a normal web browser or with telnet (terminal software). What is there to be configured? The IpSonlab needs to know which IP-address the remote computer (=the IP-address of your computer) has and which port on that IP-address will be available. As soon as this has been configured, the IpSonlab can exchange data with the remote computer (is your computer).

At the Electronical Workshop of the Royal Conservatory, we already initialized the IpSonLab, so it has a default IP-address and a default local port. The ip-address of the IpSonLab is written on the PCB (Printed Circuit Board). The local port will be 10001.

There are two ways to connect the IpSonLab to your computer:
- Direct connection between the IpSonlab and your computer; this means you have to work with a cross ethernet cable.
- Through a switch or ethernet-hub with a normal ethernet-cable. Remark: If you send lots of data through your ethernet connection, it is preferred you make a direct connection between your computer and the IpSonLab. In that way nobody else on the network will notice the amount of bandwith you use.   Configure the IpSonLab with a webbrowser Start a web browser (Firefox, Netscape, Explorer, Safari) and fill in the ip-address of the IpSonLab (Xport). If the login window pops up, just hit enter. You can protect your xport by setting a password. Default the name and password are empty. The loading of the pages will take a short while, so be patient. It will load a Java applet. Select port properties and fill in your IP-address at ‘ Dedicated connection, and remote Ip-address and remote-port. When the changes are made, make sure you save the new settings, with ‘ update settings’.

Make sure the IpSonLab is connected and the power is on. Open the terminal on your computer (both Mac and PC) and type telnet at the prompt:
telnet <enter> Then open the connection with the IpSonLab (example ip-address 10.1.60.1):
Open 10.1.60.1 9999 <enter>
The number 9999 is the port number. Within five seconds you have to hit enter again. At this time you are connected with the IpSonLab and you are able to configure all kind of settings. Be aware that the general settings are already made and the only thing that has to be changed is the remote IP-address and the remote port number (default on 10001). The next screen will show:

Change Setup:
0 Server configuration
1 Channel 1 configuration
3 E-mail settings
5 Expert settings
6 Security
7 Factory defaults
8 Exit without save
9 Save and exit
Your choice?

Select an option on the menu by entering the number of the option in the Your
choice ? field and pressing Enter.
To enter a value for a parameter, type the value and press Enter, or to confirm a
current value, just press Enter.
When you are finished, save the new configurations (option 9). The unit reboots.

** You can choose your own port number (number between 1000-10000). Be aware of the fact that some numbers are already in use (for example port number 80 for http, port number 23 for telnet)
When you are sure the values are right, press 9 to save the new settings and exit or press 8 if you are not sure you filled it in the right way. Your IpSonLab is ready to go!

Now your IpSonLab is connected to your computer and able to exchange data, you can start with Max/Msp (or any other software that can exchange Open Sound Control packages, ea SuperCollider). Within Max/Msp you can read the data from, and send data to the IpSonlab with the ‘udp-read’ and udp-write objects for PC and ‘otudp read’ and ‘otudp write’ objects for Macintosh. For further information about these objects I refer to this website: http://www.cnmat.berkeley.edu/OpenSoundControl/Max

Important: Within the ‘osc-route’ object at the receiving part, you have to fill in the /ipson route for sensor info or /sw for rotary switch info. All packages sent by the IpSonLab do have, so called, header information. You can download an example Max/Msp patch for both Macintosh and PC.

As explained in the software versions, the data communication between IpSonLab and Max/Msp, is quiet a lot of data. We are bussy to reduce and finetune these settings, so more speed can be achieved and the resolution will be high (10-12 bit). (see the dev.log page)

Max/Msp is receiving:
The first version of the IpSonLab (ipson1SHS) sends out lot's of OSC data per changes on the input. There's no data reduction of any kind. This means that within the osc-route object, the data can be read out directly (with the unpack-object)
The next version of the IpSonLab (ipson2SHS) sends out less OSC data; for 32 sensor inputs, it sends 8 times 32 bits integers. This means the data is 'compressed, or stuffed'' by the IpSonLab and that the 'de-compression, or unstuffing,  has to be done by Max/Msp

1. connect the external power also to the relayboard (H11); this is to connect the onboard safety 
diode parallel to the coil of the relay.
2. connect the gnd (ground, or zero) of the external power source to the gnd connection of the relay-board(H12).
3. The onboard relay drivers (the uln2803) can drive 500mA max. 
Make sure you do not exceed this value! 

H14 is used to connect an extra relayboard; the amount of outputs can be extended to 64.
