Issue Error: "Could not create remote directory" or "Failed to establish connection with the target device" when trying to upgrade/downgrade a Xenta 5/7/9xx controller     Product Line TAC INET, TAC Vista, Satchwell MicroNet Environment Xenta Servers Xenta 511, 527, 527-NPR, 555, 701, 711, 721, 731, 913 XBuilder Cause This error can be caused by any of the following reasons: Trying to downgrade a Hardware version 2.x Xenta Server device to System Program version 2.10 or older Internet Options are configured to use a proxy server IP communication is not properly established due to incorrect IP settings, a bad cable or a faulty device The controller is 5.1.8 or lower and Microsoft KB 2661254 or KB 2661254-V2 is installed on the PC. In this upgrade Microsoft has changed the criteria for the certificate Key. Service packs are available on the extranet to correct this issue. Download blocked because of other Windows updates SSL 2 and 3 is not activated Resolution First, establish that the System Program that you are attempting to load is compatible with hardware version of the device. The older HW 1 versions can be upgraded to System Program 5.1.2 or older. Only system program versions 2.2.0 and newer can be loaded into devices that are hardware version 2.X. Hardware Version System Program 1.0 5.1.2 or older 2.X 2.2.0 or newer 3.X 5.1.6 SP1 or newer Note: Hardware version 1 devices are not labeled as HW 1 since only one version of hardware existed at the time. Hardware devices can be identified by the lack of any hardware version printed on the Neuron ID sticker. Note: If running the firmware update software, ensure you are running as an administrator. Next, check to verify that IP communications are configured properly and are functional: Check the IP address defined in XBuilder Verify a good connection to the IP port of the controller (10Base-T port on the far right) with a crossover cable. If that is all good, then a reformat of the controller may be necessary. Connect via Hyperterminal to the unit and at the dsh> prompt type format and press enter command . This will recreate the directory structure of the controller and allow you to attempt the upgrade/downgrade again. Finally, verify that the Internet Options are not configured to use a proxy server or, if they are, temporarily change them as follows: To temporarily change this setting follow these steps: In Internet Explorer select the Tools Menu and select Internet Options. Or select Internet Options from your Control Panel. Go to the Connections tab. Click the LAN settings button. Uncheck the Use a proxy server for your LAN box. Click Ok in the LAN settings window and the Internet Options window. Complete the System Program download. Return to the Internet Options window and re-check the Use a proxy server for your LAN box in the LAN Settings found in the Connections tab. Another Matrix explaining the compatibility of each with Vista versions can be found in Xenta-Server-firmware-versus-Vista-Server-versions If you have the Xenta FW 5.1.8 or lower and KB 2661254 or KB 2661254-V2 were installed during a Windows Update you will need install the service packs. These new service pack builds have been released and are available on the extranet. See TPA-VSTA-12-0028.00 - TAC Xenta Servers, Not Possible to Download Firmware for more info. Another issue has been reported to support relating to the bit length of the Xenta server boot certificate. The Xenta server installer uses a 512 bit key length of the boot certificate, and Windows in some instances can be configured for a 1024 bit length certificate. If the issue still exists after removing the above mentioned Windows Updates, or if you are getting this error and the Windows Updates are not on your machine. Download the attached tool, Allow Weak Certificates.zip, and execute the file, chose "Allow Weak Certificates", and "Update".   Here is what the tool set: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\OID\EncodingType 0\CertDllCreateCertificateChainEngine\Config] "EnableWeakSignatureFlags"=dword:00000002 "minRSAPubKeyBitLength"=dword:00000200 If taking the preceding steps fails to resolve the issue then see the following articles for additional steps that can be taken: Xenta Server "Run" light is solid red, with no communication via Ethernet,  Fail to upgrade the TAC Xenta Server system software (firmware)  An unexpected error occurred while downloading using a Xenta Server

Issue General use of the Wireshark program. Product Line Access Expert, Andover Continuum, EcoStruxure Building Expert, EcoStruxure Building Operation, Pelco, Satchwell MicroNet, Satchwell Sigma, TAC IA Series, TAC INET, TAC Vista Environment Ethernet Networks Cause General Information on using WireShark. Resolution Wireshark is an Ethernet packet analysis programme, Which can be downloaded from: Latest version available from Wireshark Locally stored version 1.0.9 Installing Wireshark If necessary, unzip the WireShark executable file to a suitable location on the PC/Laptop you wish the programme to be installed on. Run the executable file and follow the on-screen instructions. Rules for capturing LAN traffic using Wireshark: Do not use a switch or router to connect the LAN capture PC to the network as these will filter important network activity that you will need to see. You will want to capture everything that is passing over the network at the point of concern. Usually, this means tapping into the ethernet at the Controller or controllers, that is having an issue. midBit-Technologies-LLC-10-100 is an example of a device that can be used to easily tap into the network to take the capture. The monitoring PC must see all traffic from the controller's point of view. The monitoring PC can be connected in either two ways: Connected to the network at the controller The customers IT department can mirror all the network traffic from the controllers port to another port the PC can be connected to. If connected to the network at the controllers, the connection must be made through a true ethernet hub. A hub will not selectively filter important network traffic as a switch or a router will do. More information on what a "true ethernet hub" can be found at http://wiki.wireshark.org/HubReference There are however some switches that feature port mirroring, please see How to Configure a NETGEAR Prosafe Plus Switch for Mirroring. If connected to a mirrored port, the port must mirror 100% of the network traffic to and from the controller. No filtering should be done. Once a complete capture file has been obtained it can be filtered after the fact using WireShark or EtherReal. Using Wireshark Run WireShark Start a trace by choosing the "Capture" menu and then select "Interfaces" Choose the appropriate interface. Generally, this can be identified by its IP Address, but if not, then the packets increasing are an indication. Press the "Start" button. The trace will start and will be similar to the following screenshot. After an appropriate time, the trace can be stopped by selecting "Capture" menu and "Stop" To save the capture file, choose "File" menu and "Save As".

Issue What NEMA or IP rating is a specific product? Environment All devices Cause Is a product protected against water and access by foreign objects? Resolution The Degrees Of Protection document details both the IP rating and NEMA Enclosure charts. The IP rating is made up of 2 digits, the first is the level of protection to foreign objects, the second is the level of protection to water. If a product does not specify any rating for water ingress in it's datasheet then the the second digit will be 0. The first digit relates to the size of a foreign object that can be inserted into the product. Typically many Buildings products will not allow the insertion of a finger (12.5mm approx' 1/2") and offer no water protection, so they would be rated as IP20, however it would be IP10 should they have holes of up to 50mm (approx' 2").

Issue What are the differences between the IAC 400 and the IAC 420 controllers? Product Line Field Devices, Other, Satchwell MicroNet, Satchwell Sigma   Environment IAC 400 IAC 420 Cause The IAC 400 controller is obsolete and its replacement is the IAC420. Resolution Hardware differences; The IAC 400 has 3 Temperature, 2 Analogue and 1 Digital input, where as the IAC 420 has 6 Universal inputs. Communications differences; The IAC 400 controller uses terminal 3 to earth the communications cable screening, on the IAC 420 the screening must be connected to a good earth and not terminal 3. Tables and offsets; Because the IAC 420 has different inputs that tables and offsets are changed, please review IAC Controllers - Tables and Offsets.
