If you wish to use routing over this serial network connection, then the IP addresses selected must
not lie on Wireless or Wired Ethernet networks already configured into the device. You must ensure
they set routing rules appropriately for devices either side of the network.
If you want the serial device visible as present on the Wireless or Wired network, then the local IP
address must be the same as the IP address set for the desired port. A process called “Proxy ARP”
is used to make the device visible on the network. In this process, the XYR 400E pretends that it
holds the IP address on the network, and responds on behalf of the remote device.
The result of this is similar to bridging for a single device, with some exceptions. One of these
exceptions is the inability to handle name server searches of the network via this serial link. For
example, you would encounter difficulty if you were to use Windows Explorer over the serial link
to find a PC on the wired network. For this to operate correctly you must explicitly map computer
names to IP addresses in the “LMHOSTS” file on your PC.
When in SETUP mode, the XYR 400E PPP server is enabled. This may also be used to configure
the module. Settings whilst in SETUP mode are as follows:
•
username
user
, password is
user
.
•
Serial baud rate 38400bps
•
Hardware flow control
•
Local address 192.168.123.123
•
Remote address 192.168.123.124
To configure Windows XP to establish a PPP connection to a XYR 400E in SETUP mode, follow
these steps:
