Device ManageR and the Device Discovery Utility use a broadcast scan on UDP port 30718 to automatically locate AVTECH monitors on a network.
To begin discovering the monitor's IP address, please follow the instructions below starting at step 1.
AVTECH recommends the following for initial product discovery:
- DHCP Enabled on network.
- UDP Broadcasts allowed at a computer and network level.
Please Note Before Beginning:
- The network cable must be plugged in to the Room Alert or TemPageR monitor and the switch or computer before power is connected. This ensures that the initial DHCP request will be sent successfully when power is connected.
- If the monitor has been assigned a static IP address that is invalid for the current IP address range of the network, please proceed to step 3 of this guide.
- When the Room Alert or TemPageR monitor is powered on and plugged into a network, please check the current status of the Network Jack's lights as these lights are used to determine the current state of the monitor. The left link light should be a solid green color while the right light should be a flashing green or orange. If these lights display any other patterns than this, please skip to step 5 of this guide.
1. Both Device ManageR and the Device Discovery Utility have a manual discovery feature that uses a TCP scan on TCP port 30718. This feature is helpful if the network range or specific IP address of the monitor is known.
- To access this feature using Device ManageR, click the 'Advanced Discovery Options...' button under 'Device Status' in the left menu. Click the 'Manually Add Device/s Via IP Address' button and select either 'Single IP Address' or 'Range Of IP Addresses'. Insert the desired IP address or range and click the 'Begin Scan...' button.
- To access this feature using the Device Discovery Utility, click the 'Advanced Discovery' button located under the 'Search' button. Then, select either 'Single IP Address' or 'Range IP Addresses' and enter the single IP address or IP address range. Start the scan using the 'Begin Scan' button.
2. DHCP Enabled On Network – All AVTECH monitors are initially set to obtain an IP address automatically using DHCP. DHCP must be enabled on the network for the monitor to receive a valid IP address. If DHCP is not enabled, the monitor will default to an auto IP address in the 169.254.xxx.xxx range. At this IP address, the router or system firewalls may not allow discovery because the IP address is outside of the valid network IP range. Valid assignment could potentially be hindered by a managed switch even if DHCP is enabled. If DHCP assignment is delayed in the managed switch, the DHCP request sent from the monitor can timeout and default to a 169.254.xxx.xxx Auto IP address.
- If DHCP is enabled on the network, there is a chance the DHCP server has already assigned a valid IP address even though the monitor is not discoverable. If the manual discovery option from step 1 does not discover the monitor, the IP address can sometimes be obtained by checking the DHCP server for the MAC address of the monitor.
- If the IP address can be verified by checking the DHCP server and the IP address is in range of the network, it can be added to Device ManageR and the Device Discovery Utility using the manual scan feature from step 1. This IP address can additionally be accessed by directly by typing the IP address in a web browser.
- It is also possible to create a DHCP reserved IP address on a server. Doing this and recycling the power on the monitor should allow the IP address to be assigned by the DHCP server. If this process is unknown or unable to be completed personally, please consult the local Network Administrator. Otherwise, continue to the next step.
3. If the IP address of the monitor is still not discoverable, AVTECH recommends connecting the unit directly to a computer or laptop using a cross-over Ethernet cable or spare network hub.
- Before disconnecting a computer or laptop to be used from the current network, be sure that the Device Discovery utility is installed along with a protocol analyzer (packet sniffer) application. If a preferred protocol analyzer application is unknown or not installed, a free utility called 'Wireshark' can be installed from http://www.wireshark.org/.
- Begin by assigning a static IP address to the computer's network card, then connect the monitor via cross-over Ethernet cable or spare network hub to the computer. Lastly, plug in the power to the Room Alert or TemPageR monitor to begin the connection process.
- Attempt discovery using the Device Discovery utility by clicking the 'Set IP' button. The 'Set IP' button can set an IP via the MAC address which can be found at the bottom of any Room Alert or TemPageR monitor's case. Follow the procedure as prompted by Device Discovery and remember to set the IP to a valid IP address that is within the same subnet as the IP set for the computer's network card. After doing this, the monitor should be accessible via the Device Discovery list or by directly entering the newly set IP address in a web browser.
4. DHCP alternative to the static IP settings above: While still on the cross-over cable direct connection between the computer and monitor, the Room Alert or TemPageR may also be reset back to initial DHCP factory defaults via the reset button on the back panel of the monitor (if applicable).
- For TemPageR3E, Room Alert 4E, 11E: Hold the reset button in for 10-15 seconds until the top left LED on the Ethernet jack blinks. A reset has occurred when this light on the ethernet jack goes out, then reappears 1 second later. Please release the reset button after this occurs.
- For Room Alert 24E, 26W, 32E/W: Hold the reset button in for 10-15 seconds and watch the 3 main status lights on the front of the monitor. A reset has occurred as the front 3 status lights cycle through red and then finish cycling. Please release the reset button after this occurs.
- With the unit now set back to DHCP factory defaults, change the laptop's network card settings to automatically obtain an IP address as opposed to specifying a static IP. Start up the Device Discovery utility and click 'Search' to locate the monitor.
- If the Device Discovery utility methods are not working and the above steps have not located the monitor, start the protocol analyzer application, Begin packet capture and recycle the power on the monitor. Look for incoming packets coming from the MAC address of the monitor (located on a sticker on the bottom of the monitor's case or on the back of a rack mount kit if applicable). One of these packets should contain the source IP address of the monitor. Once this IP address has been obtained, configure a static IP address on the laptop or computer that is within a valid network range in relation to the IP address assigned to the unit as in step 3 (i.e. IP of unit: 192.168.2.3 - IP for computer or laptop: 192.168.2.4). The monitor can now be directly accessed by entering the IP address in a web browser.
5. If the above trials have been unsuccessful in discovering the IP address of the unit, please email Support@AVTECH.com with the packet capture obtained in step 4 attached to the email.
