2. Commissioning
Power is supplied via a 5V USB unit which is connected to micro USB port X14 (between
the two DSUBs). The ipCore can provide supply for modules at the RS485 bus. Here,
the maximum current that can be supplied via the power supply unit must be taken into
account. After deduction of the own consumption of max. 1W@5V, 1800mA will remain in
a 2A power supply unit for the IO cards connected.
2.1. RS485
The RS485 bus of the ipCore is located at X13 (DSUB socket) on pins 4 (RS485+) and 6
(RS485-). A gpio.Net IO card can be connected directly by means of a normal serial 1-1
cable. In a similar manner, all other cards can be hung in a row by connecting the DSUB
socket to the DSUB plug.
2.2. USB
The two USB host ports X9 can also be used to connect a gpio.Net IO card. This card then
serves as a gateway between the USB and all other IO cards connected to it.
2.3. Booting and usage
After switching on the ipCore (power supply is present, push button SW1 has been briefly
pressed), the Modbus TCP server, the REST interface and the database start automatically.
User-defined scripts can also be executed automatically.
The gpio.ipCore obtains its IP address on its own via DHCP and uses the mDNS protocol
(Avahi, Bonjour, Zeroconf) to publish its IP. An ipCore can be accessed on “ipcore.local”.
The device responds to command “ping ipcore.local” in a shell (Windows/MAC/Linux). The
REST interface can be accessed via URL http://ipcore.local/gpio by using a browser.
To ensure to above method works, Bonjour (from Apple) must be installed in Windows,
and Avahi must be installed in Linux. For more configurations of the system and to upload
the scripts, the device can be accessed via SSH.

2.4. Useful tools
The use of the following tools is recommended for easy access to the gpio.ipCore in
Windows: Putty, curl, winscp. Linux usually brings all necessary tools along already.
2.5. Changing root password
We strongly advise the user to change the default password for root access. In order to do
so, login via SSH using the information from Table2.1, “Default login information”.
