3. 3 13 Serial Port Configuration The XYR 400E has an RS 232 and RS 485 port for serial communications These ports may be used for different purposes The XYR 400E offers three different serial functions which are PPP server Serial Gateway and Modbus TCP to RTU Gateway 3 13 1 RS 232 PPP Server The XYR 400E can be used as a PPP Server to connect the wireless Ethernet system to serial devices via the RS232 or RS485 serial ports PPP Server enables a network connection to the XYR 400E over a serial cable This is much like dial up internet The maximum serial data rate is 115 200bps Hardware or Software flow control may be selected With minimal configuration on the PC you may use Dial up networking in Windows XP to connect to the network via the serial port For the XYR 400E users must configure the local IP address for the XYR 400E and the remote device IP address Some care must be taken in selecting these IP addresses 47 XYR400E Ethernet Modem Version 1 5 1 08 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

10. 5dB 6dB Installation tips Connections between the antenna and coaxial cable should be carefully taped to prevent ingress of moisture Moisture ingress in the coaxial cable is a common cause for problems with radio systems as it greatly increases the radio losses We recommend that the connection be taped firstly with a layer of PVC Tape then with a vulcanizing tape such as 23 tape and finally with another layer of PVC UV Stabilized insulating tape The first layer of tape allows the joint to be easily inspected when trouble shooting as the vulcanizing seal can be easily removed Where antennas are mounted on elevated masts the masts should be effectively earthed to avoid lightning surges For high lightning risk areas surge suppression devices between the module and the antenna are recommended If the antenna is not already shielded from lightning strike by an adjacent earthed structure a lightning rod may be installed above the antenna to provide shielding 2 2 1 Dipole and Collinear antennas A dipole or collinear antenna transmits the same amount of radio power in all directions as such that are easy to install and use The dipole antenna with integral 5 metres 15 feet cable does not require any additional coaxial cable however a cable must be used with the collinear antennas Collinear and dipole antennas should be mounted vertically preferably 30 cm 1 foot away from a wall or mast to obtain maximum range

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 LMHOSTS file on your 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 e username user password is user e Serial baud rate 38400bps e Hardware flow control Local address 192 168 123 123 e 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 Network Connections File Edit View Favorites Tools Advanced Help Bak d 12 Search Folders Address Network Connections ball co Name Type Status Device Name Phone or Host Address Direct ee F test PPP Direct Disconnected Firewalled Communications cable Change Windows Fire cable be settings LAN or High Speed Internet S

Bridge Operation Bridges are typically used to connect sections of the same IP network together By default the XYR 400E is configured as a transparent bridge When a transparent bridge is started it learns the location of other devices by monitoring the source address of all incoming traffic Initially it forwards all traffic between the wired Ethernet port and the wireless port however by keeping a list of devices heard on each port the transparent bridge can decide which traffic must be forwarded between ports it will only transfer a message from the wired port to the wireless port if it is required A bridge will forward all Broadcast traffic between the wired and wireless ports If the wired network is busy with broadcast traffic the radio network on the XYR 400E can be unnecessarily overburdened Filtering may be used to reduce broadcast traffic sent over the radio Refer Section 3 12 for how to configure a filter By default a transparent bridge does not handle loops within the network There must be a single path to each device on the network Loops in the network will cause the same data to be continually passed around that loop Redundant wireless links may be set up by enabling the bridge Spanning Tree Protocol see section 3 9 Spanning Tree Protocol for more details 3 or 4 Address Mode There are two different operating modes that affect bridge operation for a XYR 400E client station 3 Address Mode or 4 Address M
