Compu-Aire
To start the pCOWeb with default parameters, proceed as follows:
When the pCOWeb is off:
•
switch on the controller controller with the pCOWeb already inserted and hold the
button for at least 20 s, until the status LED starts flashing SLOWLY 3 times, red-dark;
•
release the button while the LED is flashing, after having flashed 3 times, the LED turns
green, then, to confirm the recognition of the button, the LED will flash QUICKLY 3
times, red-dark.
•
To complete the pCOWeb boot phase, wait approximately 50 s until the status LED
flashes regularly. From this moment on, the pCOWeb can be accessed via the network
When the pCOWeb is already on:
•
Restart the pCOWeb software (see “Restarting the software”)
•
After restarting, proceed as above for when the pCOWeb is off.
Note:
In “factory bootswitch parameters” mode, the pCOWeb does not save the
parameters recalled, but simply uses them, and therefore, when next restarted without
pressing the button, it will use the parameters set by the user (if just acquired, with DHCP)

Restarting the software
To restart the software when the board is in stable operation (that is, with the status LED
flashing regularly), press and hold the button for between 5 and 10 seconds; after around 10 s
from releasing the button, the status LED will stop flashing, and after a further 15 seconds the
software on the board will restart.

Configuration
Note:
For the correct operation of the pCOWeb, a number of basic parameters need to
be set, such as the IP address and Netmask; each device connected to an Ethernet
network, to communicate with a host, must have a unique IP address.
PCOWeb is supplied with the DHCP function already active. Therefore, in a network served by a
DHCP server, pCOWeb will automatically acquire the necessary parameters without requiring
configuration. In the case of a network without DHCP, the parameters need to be configured
manually (see the “Accessing the user configuration...” section).
Accessing the user configuration
(via Ethernet network and configuration web pages)
Automatic network configuration
(DHCP): ask the network administrator for the address that
has automatically been assigned to the pCOWeb already connected; the administrator will need
to know the MAC ADDRESS of the pCOWeb.
Network without DHCP
: when first using the board, it is recommended to connect pCOWeb
directly to a computer using a crossed Ethernet cable; then start the board with the “factory
bootswitch” parameters (see “Pushbutton”).
