General Settings

Regulatory Domain – Please select regulatory domain that is most appropriate to your location.

Supported Regulatory Domains and allowed frequency ranges are defined as follows:
Europe – 5500 – 5700 MHz with DFS,
OFCOM UK – 5735 MHz, 5755 MHz, 5775 MHz, 5835 MHz with DFS,
USA – 5745 - 5825 MHz,
Far East & Africa – 4920 – 6100 MHz (236 channels).

Device Name - This is the system name for easy identification of the OSBRiDGE 5NXt unit.
ESSID - An ESSID is the unique name shared among peers on your wireless network. The name must be identical for both OSBRiDGE 5NXt devices to connect. It shall be up to 32 characters length.
WLAN Operational Mode - Wireless LAN Operational mode for the device. Available modes are Master and Slave. To create a Point to Point wireless link device on one side of the link should be configured to operate in Master mode and the device on other side of the link should be configured to operate in Slave mode.
Preferred BSSID – MAC Address of the other OSBRiDGE 5NXT device this one should connect to. If set to 00:00:00:00:00:00 then only ESSID is taken into account when connecting to other network peer.
Frequency - Here you can select frequency for the device to operate on. Depending on configured Regulatory Domain this will either be DFS where user can not manualy select frequency (ETSI and UK regulatory domains) or list of allowed frequencies for manual selection (USA, Far East & Africa domain).
Channel Width: - Channel width the device uses to operate. Available values are 20 MHz (default width), 40 MHz, 18 MHz, 16 MHz, 14 MHz, 12 MHz, 10 MHz and 5 MHz. The smaller channel width is, the lower real speed obtained over wireless link is. However, the benefit of using smaller channel widths is that they normaly handle interference much better than the regular width channels.
Noise Immunity - This option enables special algorithm to handle transfer in extermely high noise areas. This option should be enabled only if the operation on selected frequency is not possible due to interference. Also, this option reduces effective data transfer speed over the wireless link.
Scan Range - This option defines frequency range that should be used when scanning for other network peer in slave mode. This frequency range must be within range of frequencies allowed in configured regulatory domain.
Enable Stream 1 - This option allows disabling or enabling transmit/receive on the first RF stream of MiMo radio.
Enable Stream 2 - This option allows disabling or enabling transmit/receive on the second RF stream of MiMo radio.
Carrier Sense - This option allows to disable standard 802.11 CSMA/CA backoff mechanism. Disabling 802.11 CSMA may improve performance when operating in area with noise generated by other (especialy non 802.11 compliant) devices.
IP Operational Mode
Bridge - Bridge works at OSI model Layer 2. This means it does not know anything about protocols, but just forwards data depending on the destination address in the data packet. This address is not the IP address, but the MAC (Media Access Control) address that is unique to each network adapter card. With a Bridge, all your computers are in the same network subnet, so you don't have to worry about not being able to communicate between computers or share an Internet connection. The only data that is allowed to cross the bridge is data that is being sent to a valid address on the other side of the bridge.
Router - Router is an OSI model Layer 3 device, and forwards data depending on the network address, not the hardware (MAC) address. For TCP/IP networks this means the IP address of the network interface. Routers isolate each LAN into a separate subnet. Routers provide bandwidth control by keeping data out of subnets where it doesn't belong, however routes need to be set up before they can get going.
Use Management VLAN - This option configures VLAN management to access the OSBRiDGE 5NXt device.
Accessing the device for management will only be possible from VLAN interface with specified VLAN-ID. Packet Aggregation - Enable or Disable built in packet aggregation. Packet aggregation joins many smaller ethernet packets and sends them over wireless link as one, large wireless packet. This way the real data transfer speed is greatly improved. This option should be left enabled by default and configured only when there is problem with data transfer performance over wireless link.
Watchdog – If enabled then OSBRiDGE 5NXt device will send 3 ICMP Echo Requests to the specified IP address, each in 60 seconds interval. If there is no single ICMP Echo Reply to any of these requests, then the device will reboot itself.
The device also has second hardware watchdog built in, that checks for critical operational parameters and reboots the device, should the system hang or become unstable. That watchdog operates all the time, regardless of the ping watchdog configuration.
Run Web Server on Port – TCP Port for the built in management WEB server to operate.
Web Login Timeout – Enter the value the management Web session should be kept alive without any action from the user.
NTP Server - Configure IP address of the external NTP (Network Time Protocol) server OSBRiDGE device will obtain current time from at startup time. The device will attempt connection to this NTP server 60 seconds after full system start.
SNMP Server - Configure operation of built in SNMP server. Community string required to access SNMP is configured in Password Settings tab.
Distance to the Peer (kilometers): - Configure distance between OSBRiDGE 5NXt device and it's network peer. This is a very important value to configure, if set too low, then the communication over wireless link will be not possible or erratic at best. When in doubt it is better to set distance longer than the real one rather than too short one. The value should be set as integer number, rounded up.
XTRange Enabled – Enable or Disable OSBRiDGE proprietary XTRange protocol that improves pefromance over long distance links.
Transmit Power - Configure Device Transmit Power, available values depend on configured Regulatory Domain.
WLAN Speed - Configure fixed wireless interface Transmit Data Rate or Auto for auto speed selection.
Multicast Optimization - When enabled multicast packets are transmited using more advanced algorithm and applications that use multicast for transport (ie. some surveilance cameras) can achieve much better performance.
Encryption - Select generic encryption algorithm
WEP - Wireless Equivalent Privacy
WPA-PSK TKIP - Wireless Protected Access
WPA-PSK CCMP - Wireless Protected Access 2 (WPA2)
WEP Key – Enter WEP encryption key here. Keys are entered as hexadecimal numbers in following format:
64 bit WEP: xxxx-xxxx-xx
128 bit WEP: xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xx
156 bit WEP: xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx
WPA Pre-shared Key - the key is entered as 8-63 characters long string, ie. OSBRiDGE.

IP Settings

Bridge mode

Device IP – Enter device IP address here.
Subnet Mask – Enter network subnet mask here.
Default Gateway – IP address of a router where traffic going outside of the local network will be forwarded.

Router Mode

Wired Interface IP – Enter IP address of the wired interface here.
Wired Interface Mask – Enter wired network subnet mask here.
Wireless Interface IP – Enter IP address of the wireless interface here.
Wireless Interface Mask – Enter wireless network subnet mask here.
Default Gateway – IP address of a router where traffic not destined for defined routes / local routes will be forwarded.
Defined Routes – This table displays currently defined static routes. To delete a route select "Delete" checkbox and press Submit on the bottom of the page. Please note that it is not possible to delete first two entries – direct routes to local interfaces.

Add Route:
Direct – on wired or wireless interface - When router has two or more IP subnets directly attached to its different interfaces, it can route IP packets between those subnets using a direct route. A direct route consists of an IP Address which specifies the basic IP address to route, a Subnet Mask which defines the class of IP addresses that will be routed, and an interface which specifies where the IP subnet is attached. When an IP packet addressed to a system on the directly routed subnet arrives at the router, the router will send it directly to the target machine on the interface specified. When entering direct route use 0.0.0.0 as Gateway.
Indirect - When router needs to send IP packets between IP subnets which are not directly connected to one of its interfaces, it must have an indirect route for sending those packets. An indirect route consists of an IP Address which specifies the basic IP address to route, a Subnet Mask which defines the class of IP addresses that will be routed and a Gateway that will relay the IP packet. When an IP packet addressed to a system on the indirectly routed subnet arrives at the router, the router will route it over to the specified Gatway to be routed further.

Spectrum Analyzer

Spectrum Analyzer is an utility that lets the user scan specified frequency range to see what other transmiters are operating there. It is strongly recommended to use this tool right after the first link deployment to select channels that are interference free, for best possible device and link performance.

After finishing the scan you can point using your cursor on the specific signal bar on the graph to see frequency and signal level reading for that specific frequency.

Emergency firmware restore procedure.

Should the OSBRiDGE device fail or loose power during firmware upgrade the built-in bootloader allows easy firmware restore.


This is the step by step procedure required to perform firmware restore:
1. You need to obtain tftp server software, the free one is available at http://tftpd32.jounin.net/
2. Install tftpd32.exe into the catalog where firmware files are located
3. Rename the firmware file (ie. OSBRiDGE_5NXt_1.06R.bin) to zImage
4. Change your computer IP address to 192.168.1.23 netmask 255.255.255.0
5. Connect the OSBRiDGE device to the computer via cross-over cable or via network switch
6. Turn on the OSBRiDGE device, it should initiate the transfer automaticaly, automaticaly reflash and reboot itself.

Resetting device to default settings.

In order to reset OSBRiDGE device to factory default settings you need to use OSReset software available for download at http://www.osbridge.com/?q=en/software

OSReset will locate any compatible OSBRiDGE device regardless of its IP address located on the same physical subnetwork with the computer it is running on.

After selecting the device you want to reset enter "Reset to Default Password" in the Password: field and press button.

If you have changed Reset to Default Password to one you no longer remember then please email us at support@osbridge.com stating device type and MAC Address and we will provide you one time, generated password that will let you reset the device to factory default settings.
