Inserted or changed with LCOS 8.50
When configuring wireless P2P links, the remote sites usually recognize one another by a particular feature of the P2P partner; either the station name or the MAC address as entered into the access point's configuration.
However, when changing P2P partners, it is not possible to enter a fixed parameter into the configuration. For example, if you want to set up a P2P link between two train carriages to offer IP services on the whole train, the P2P partners could change according to the combination of carriages.
In these cases, the access points can exchange their MAC addresses via the serial interface. To do this, interconnect the devices via two wires of the serial interface. You can then set the P2P peer recognition to the value 'Serial autoconfig'. You then configure the P2P links as if for a fixed installation of the access points.
In the default state, the WLAN modules are disabled. When the devices are turned on, they first exchange their MAC addresses, the WLAN modules are activated and the P2P link is established automatically.
