Setting up a Temporary DHCP Server
The processing module has an Ethernet configuration mode setting which has been set to DHCP by
default. If your network does not have a DHCP server, the units will not get a valid IP address
automatically. In this case, Cerebrum/Cortex is not able to detect the card. The initial setup of the units
will only allow for getting an address assigned via a DHCP server. After the DHCP server has assigned an
address to the module, you can add it to the Cerebrum/Cortex system view and change the Ethernet
configuration mode setting to manual mode, with the static IP address you need.
1.
Set up the IP Address of the PC on which Cerebrum/Cortex is installed, to the range which will be
used by the DHCP server, i.e. 192.168.1.1/255.255.255.0
2.
Install a DHCP server to your laptop. You can use http:/tftpd32.jounin.net/tftpd32.html (free of
charge, open source)
3.
Run the DHCP server application and go to
Settings
->
DHCP
tab -> and set a DHCP pool definition
that starts with 192.168.1.1, with a pool size of 50 and a lease time of 2880.
4.
Go to
DHCP options
and set
Def. router
(Opt3) to 192.168.1.254 and
Mask
(Opt1) to 255.255.255.0
5.
Open Cerebrum/Cortex and in
Network
->
Add Generic Device
->
ACP2 device
, select the IP
address which has been assigned to the Neuron module (most likely 192.168.1.2).
Module's IP Address is Unknown
If the module has been set up with a static IP address, but the address is unknown, follow these steps to
retrieve the address:
•
Identify the MAC address of the module.
•
Install Bonjour Browser, an application which can search the network for MAC addresses.

•
Run the application and find the corresponding MAC address's IP address.
•
Add the module to Cerebrum/Cortex using the IP address assigned to the module's MAC address, as
described in "Setting up a Temporary DHCP Server".
