  Yeastar S-Series Linkus with DrayTek Routers
Posted by: admin - 22-11-2019, 11:53 AM - Forum: Asterisk - No Replies

How to setup Linkus with DrayTek Routers.

1) Create Port Redirection Rules as follows:
- Public Port UDP 9850 to Private Port 8111 and to the IP of the PBX
- Public Port UDP 6023 to Private Port 5060 and to the IP of the PBX

   

2) Create an Open Port Rule
- UDP Start 40000 - End 42000 to Private IP of PBX
- UDP Start 10000 - End 12000 to Private IP of PBX

   

3) If you haven't already, install the Linkus App on the PBX and configure it for the Ports you defined above like this:

   

4) On the PBX, go to Settings, General, SIP then NAT and configure the settings as follows:

   

5) Enable the required Extensions for Linkus and click on "Send Email" to send a link to the Users to install the App.

   

Some Yeastar FAQs and Documentation suggest enabling the PBX Firewall which is always a good idea.
However, we have encountered no-audio issues at some multi-site locations which we never figured out when the Firewall was enabled.
At these sites it's always important to ensure your perimeter Router/Firewall is hardened and that your UDP Port 5060 is exposed only to your SIP/VOIP Provider's IP.

  Outlook Resending Old Sent Items
Posted by: admin - 25-10-2019, 05:24 PM - Forum: General Discussions - No Replies

Emails previously sent months ago are sent again.
Affected site uses Exchange 2007 (SBS 2008) and Outlook 2007.
This has been randomly going on for years and we never really found a solution out there.

Narrowing it down to the Computer (Email Account) responsible was easy and we further investigated the issue.

Looking in the Outlook Folder C:\Users\Username\AppData\Local\Microsoft\Outlook we found a bunch of Temp Files (0K in size) corresponding to the same amount of sent Emails.
These files begin with "BIT" with some examples shown here:

   

Out of "suspicion" that the Outlook OST File or Profile was corrupt, we turned off Cached Mode (Cached Exchange Mode) and verified that there were no Sent or Outbox Items pending to be sent.

Without doing anything else, we re-enabled Cached Mode and opened Outlook - suddenly over 50 previously sent Emails suddenly appeared in the Outbox about to be sent again!
So it's without doubt that there is corruption somewhere along the line and that "Cached Mode" is a major factor.

There is a lot of misleading info out there on DuckDuckGo (more so on Google) leading to Exchange as the cause.
For us it was not Exchange but Outlook.

Due to the age of Outlook a permanent fix is not going to be pursued - we are simply going to disable "Cached Mode" until executive decisions are made to upgrade the Office Suite.

  Windows Server SSD Optimisation
Posted by: admin - 15-03-2019, 03:28 PM - Forum: General Discussions - No Replies

How to optimise Windows Server for SSD Drives and reduce the Write IO to increase the lifespan.

1) Enable TRIM
Run the command “fsutil.exe behavior query disabledeletenotify” to check the status.
Should show result of “DisableDeleteNotify = 0” (enabled)
Windows should automatically enable TRIM on your SSD Drive, if it does not then run the following command to enable it:
fsutil behavior set DisableDeleteNotify 0

2) Disable Prefetch
Open Regedit:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
EnablePrefetcher = 0
Reboot

3) Disable Superfetcher
Stop and disable the Superfetch Service

4) Disable Indexing
Stop and disable the Windows Search Service (WSearch)

5) Disable Write Cache (not used by SSD Drives)
Under Computer Management, Device Manager, Drive Properties, Policies:
Disable (uncheck) Enable write caching on the device and which will also disable Turn off Windows write-cache buffer flushing on the device

6) Turn off System Restore for the OS Partition
Under Control Panel, System, Advanced system settings, System Protection tab:
Highlight the Partition and click on Configure and select Disable system protection

7) Turn off Hibernation (may be tuned off already if Hyper-V is installed)
Run the command “powercfg –h off

8) Set the Page File Initial Size and Maximum Size to the same Maximum figure.
IE: If you have 32GB RAM then the Initial and Maximum should be set to 49152 (1024 x 32 x1.5) (48GB).

9) Disable Defrag
Stop and disable the Disk Defragmenter Service.

  BroadLink RM Pro+ and IHC App Missing Timers
Posted by: admin - 05-03-2019, 11:54 AM - Forum: Home Automation - No Replies

I setup multiple RF Remotes for my house blinds and created Scenes with Timers over a year ago.
This has been running flawlessly.

Today I wanted to change the Schedule of the Timers and was horrified that the Timer Functions have been removed from the current (updated) App Version (1.9.23)!

I contacted support at BroadLink and this is their comment:
"The timer function of appliances added via 'user defined' path has been removed due to the system conflicts." 

Now I am stuck with existing Timed Schedules that I cannot change or remove (yes, even though they have removed the Timer function from the App the Timers are still working).

Anyone in the same boat?

  WVC Modem and the KDM Monitoring System for WVC Micro Inverters
Posted by: admin - 05-01-2019, 02:49 PM - Forum: Alternative Power - Solar, Wind & Hydro - No Replies

WVC Modem and the KDM Monitoring System for WVC Micro Inverters

This is my review of the WVC Modem and KDM Monitoring System for WVC Micro Inverters manufactured by Dongguan KaiDeng (KaiDeng Energy Technology).

Please note that the WVC Modem does not support the 2018 Version of WVC Micro Inverters.
For the 2018 Version of the WVC Micro Inverters use a “WVC WiFi (Wireless) Modem” which is very different to the “WVC Modem” and not reviewed here.

The KDM Monitoring System consists of a Modem that uses 433MHz RF to communicate with the WVC Micro Inverters and some rather rudimentary Software called [obviously] KDM System.

I purchased the WVC Modem (as it’s called) at the same time I purchased a bunch of WVC-600 Micro Inverters (which I reviewed separately here: http://www.computersense.co.nz/forums/sh...hp?tid=245).

What you get in the Box:
You get the WVC Modem, Antenna and KDM System Software. Depending on the “bundle” purchased, the supplied accessories will vary (Serial Cable and/or extended Antenna).
   
 
The basic WVC Modem has a Serial Port to connect to a PC – the one I purchased came with a Serial to USB Cable so keep this in mind when purchasing as they are sometimes sold separately.
Also, the one I purchased came with a free-standing Antenna with a 2.5M cable which proved to be invaluable soon after installation.

Installing
Installing the KDM Software is pretty straight forward.

You only need to configure two things; 1) the Serial COM Port that your PC recognises the Serial Cable on and 2) enter the 4-digit Hex Numbers of each Inverter (IE: 85F2).
Remember to make note of these numbers when installing the Inverters and their locations and/or the panels they are connected to (I had to remove a couple of panels to get to the Inverters because I forgot to record their numbers – don’t make the same mistake).
   

Operation
This is NOT a WiFi (Wireless) Modem so don’t expect miracles – the Modem simply receives broadcasted RF Data from each Inverter so the Inverter’s Status can be monitored on a PC.

The WVC Modem does NOT “buffer” Data (store historic Data) – meaning that, if the KDM App is closed (or the Computer goes to sleep or is turned off), no output from the Inverters are recorded which impacts the overall recorded power generated.

If you want to send Data to the Cloud then you need to get the 2018> version of the WVC Inverters and their supported WiFi (Wireless) Modem then setup a Cloud Account on the KDM Website.
   

My Review
The KDM System (Modem and Software) is very basic and sufficient to monitor the health/status of the WVC Inverters. You pretty much get what you pay for (which is not a lot).

For me, I am OK with the KDM System as it does a good job at real-time monitoring of the Inverter’s output. I haven’t yet had an Inverter failure but, if an Inverter failed, it would be pretty easy to identify it.
Recording of historic data is a bit of hit-and-miss and explained here:

At least once a day I notice that one or more (random) Inverters don’t show a satisfactory output.
If I close the KDM Software then re-open it (close it completely, don’t minimise) then the Outputs show a satisfactory level.

If left unnoticed for long periods of time, the total output recorded is way under-reported.

Just as I am writing this review I again noticed a measly 20 watts coming from two Inverters that should have been producing 300W+ each - I closed the app then re-opened it – suddenly the output of the recorded Inverter jumped to 323W!

Sometimes when this happens, closing then re-opening the App doesn’t work – only power-cycling the WVC Modem sorts it out. This is not an output fault of the actual Inverters but a “monitoring” issue. If left unnoticed for long periods of time, the average output for the recorded periods becomes totally inaccurate.

So, without constantly checking multiple times a day that the App is doing what it’s meant to do, you will NEVER get a full and accurate recorded output.

The signal strength of the RF between Inverts and Modem is pretty good – I had a bit of an issue at first due to the distance between my Inverters and the Modem which was worsened by the tin roof on the house. This resulted in some of the Inverters showing as failed because the Modem could not connect to the Inverters – fiddling around with the antenna position resolved the issue.

I use the WVC-600 Inverters which have two panel inputs. Other Inverters like the WVC-1200 have four inputs for four panels.
The KDM Software can’t monitor individual Panels (individual inputs on each Inverter) – only the collective output of each Inverter. If one panel is disconnected (or fails), the overall output of the Inverter drops and there is no way (using the Software) to identify which of the two panels it is (or whether the actual Inverter input is at fault).

In summary, the KDM System is a good (but rudimentary) tool for inspecting the health of your solar array and identifying the proximity of the failure up to the number of panels connecting to each Inverter. The average output recorded (not generated) of your array can be severely affected when the Modem/Software gets a little confused (which is quite often).
I did have a play with setting up a Cloud Account on the KDM Website to see what the new generation of KDM WiFi (Wireless) Modems could do. I was really disappointed in the English translation of the Website and difficulty of use – but the new generation seems to be in its infancy and I may revisit and upgrade the WVC Inverters in future to play with.

  FC-7688 Alarm Not Keeping Date/Time
Posted by: admin - 02-01-2019, 04:35 PM - Forum: Home Automation - Replies (1)

I have an FC-7688 Alarm that does not keep the programmed Date/Time and, after a few seconds, reverts back to default Date/Time after being programmed either via the Web Interface or the Control Panel.

The Date/Time is set and Saved as follows:
   

After a few seconds the Date/Time reverts back to factory default:
   

The correct Date/Time is displayed on the Control Panel too but also (after a few seconds) reverts back to the factory default time.

I suspect that it has something to do with the GSM overriding the Date/Time (I am not using GSM or have a SIM Card installed)?

Web version is: V0.003
Hardware Version is: V0.004
Software Version is: V0.017 SIA_TCP May 5 2018 09:20:41

  Hyper-V Generation 2 VM - No UEFI-compatible file system was found.
Posted by: admin - 13-12-2018, 03:42 PM - Forum: Virtualisation (Hyper-V and VMware) - No Replies

Once you have met all the requirements for a Generation 2 Hyper-V Virtual Machine (64-bit Guest OS and OS that is on the supported list etc.) you may encounter the following error when trying to boot the VM from your ISO:

SCSI DVD     (0,1)       No UEFI-compatible file system was found.

   

Solution: Make sure that the ISO you are installing/booting from is NOT located on a URL or the Folder it is located in is NOT Shared.
Bizarre but true!

  Windows 10 Sleep and Monitor Wakeup Problems
Posted by: admin - 12-12-2018, 02:16 PM - Forum: General Discussions - No Replies

You are no doubt reading this because your monitor/s don’t wake up properly after your PC enters Sleep mode or tries to come out of “Turn off Display Mode” (Turn off Display after a set period of time).

You can either disable Sleep Mode entirely or, if that is not an option for you, set advanced Power Options as follows:

Open “Power Options” and select “Change Plan Settings” then “Change Advanced Power Settings”.
Under “PCI Express” set “Link State Power Management” to “Off” – this is the main culprit.

You may also want to turn off (Disable) “USB selective suspended setting” if you find that the USB Mouse or Keyboard doesn’t respond to input.

While everyone is in favour of saving power, extending the longevity of hardware or protecting your privacy when you are away from your PC, you will no doubt encounter issues with Windows 10 with either Sleep of “Turn off Monitor” Modes.

Personally, I choose never to put my PC to Sleep and rather prefer to Turn off the monitor after a pre-set time. My reasons are clear in that I have critical monitoring software installed that “stalls” when the PC enters Sleep Mode.

Figure out what will work for you – I mostly find that having both Sleep Mode and “Turn off Display” creates a headache when it comes to waking up my 3 monitors.
