Hiro H50113 USB modem is Microsoft Windows Server 2012 Compatible

First, pls connect the modem to an USB 2.0 port. (Not USB 3.0 since some of the USB 3.0 chipsets are not 100% USB 2.0 backward compatible when using modem)

Win 8.1 FXST30.dll is the problem. Pls download the correct version below and replace it.
You may have to TAKE OWNERSHIP to do so, as this is a system file.

For Win 8.1 32-bit
http://www.hiroinc.com/drivers/Software/FXST30/Win732/FXST30.dll

For Win 8.1 64-bit
http://www.hiroinc.com/drivers/Software/FXST30/Win764/FXST30.dll

The problem, which first surfaced in W8, is caused by a DLL file: FXST30.dll.
To fix the issue, copy the file from a W7 installation or download from http://www.hiroinc.com/drivers/Software/FXST30, then replace the W8/8.1 FXST30.dll with that file. It resides in C:\Windows\System32.

In order to do so you must first "take ownership" (have permission) of the W8/8.1 file. An easy way to achieve that is to download this, which will create a right-click "take ownership" context menu item. Though the site offers this for "Vista" it's good for W8/8.1 as well.
Add "Take Ownership" to Explorer Right-Click Menu in Win 8.1 8 7, http://www.howtogeek.com/howto/windows-vista/add-take-ownership-to-explorer-right-click-menu-in-vista/

Once the new file is in place, FAX should work normally. Be aware however that if you run the system file checker (SFC), the bad file will be restored, so keep the W7 DLL on hand.
http://www.eightforums.com/general-support/27582-fax-service-broken.html

**Alternative way to resolve the issue, pls connect your H50113 Ext. USB modem to an USB 2.0 port directly. Download the file http://www.hiroinc.com/drivers/Software/FXST30 and paste it to C:\Windows\System32\ folder

In order to do so you must first "take ownership" (have permission) of the W8/8.1 file.
Grant Permissions to everyone.
a. Go to C:\Windows\System32 and then right click on System32 folder and choose properties.
b. Then go to security tab and click on advanced
c. now click on Find Now and choose everyone and click Ok.
d. Then again click Ok and now click on Allow => Full control => Ok.
Copy the downloaded FXST30.dll file and paste it into the System32 folder.
Restart the computer and perform Windows Fax and Scan to test sending and receiving function.

There is 2 types of slot that is been used on Win 7 and later motherboards.
PCI and PCIe

PCI
http://en.wikipedia.org/wiki/Conventional_PCI

PCIe
http://en.wikipedia.org/wiki/PCI_Express

If your slot is a PCIe, pls choose H50113 External USB modem since PCIe modem is EOL (Phase Out) in 2011 due to no chipset available.

A standard bracket is approximately 4.75" from top to the bottom while a low profile bracket is measured at 3.2"

The height for low profile bracket is approximately 3.2”. The height, size and retention bracket details for Low Profile PCI as developed by Intel and adopted by PCI-SIG are almost identical with those defined by Intel for the Low Profile version of the Communication and Networking Riser (CNR) Specification. For detailed information, please refer to the URLs below for more information.

When a new fax machine is installed, it can be difficult to determine if it is setup properly. While you could determine if your fax machine is properly configured by sending a test fax to a friend, family member or business with a fax machine, you can also do so using a free service provided by HP. The HP service is free of charge, and saves your peers from the inconvenience associated with the test fax.

Send a one page black and white text fax to 1-888-hpfaxme (1-888-473-2963).
When your fax is received by the HP Test Fax Service, we will generate a return fax to you within five minutes confirming that we received your fax. This verifies that you can both send and receive a fax with your fax machine.

http://support.hp.com/us-en/document/c00259105

Pls open Windows Fax and Scan and check if both of the send/receive options are checked under Tools\Fax Setting\

Other check up

Is the modem connected directly to the USB 2.0 port on your computer?
Are you able to send/receive fax using a regular fax machine and the telephone line?
Are you able to send fax using the modem and the telephone line?

How to re-establsih the link between presenter and USB transmitter

How to activate/deactivate the laser pointer

HiRO presenters are working at the frequency of 2.4GHz. However, there are other devices that work within this frequency as well, such as cellular phone, cordless phone, or even microwave oven. Therefore, it is possible that the presenter's link with USB transmitter may be interfered by those neighbors.

The symptom of broken link between presenter and USB transmitter is that all the buttons & directional pad are not functional. However, the laser pointer should still work because this feature does not require any communication with USB transmitter. Therefore, please follow the steps below:

(1) Please refer to the following URL to see if the laser pointer is working or not.

How to activate/deactivate the laser pointer

If the laser pointer is working, please go to the 2nd step. Otherwise, please contact us at service@hiroinc.com

(2)Please refer to the following URL to re-establish the link:

How to re-establsih the link between presenter & USB transmitter

Via 802.11n protocol, Our H50191 is designed to achieve the maximum speed of 300 Mbps, while H50193 & H50194 can get up to 150Mbps.

Current wireless routers should be designed in “regular” 802.11n mode. However, please make sure that your 802.11n router is not using the older “draft-N” mode, which sometimes can result in communication problem between wireless network card and router and may result in the connection speed of 54Mbps (802.11g mode). In addition, due to the router’s MIMO design & the configuration of antenna (it may be running 1x transmit, and 1x receive as there are only 2 antenna shown), it may be more common to see your connection around 150Mbps.

For either scenario above, you may need to contact your router's manufacturer for more support.

After resolving the issues mentioned above, if the connection speed is still at 54Mbps (802.11g mode), please go into your router setup and change the following security protocols:

Change the security mode from WPA-Personal to WPA- or WPA2-Personal
Change the cipher type from TKIP to TKIP and AES

Save the setup into your router. You may need to restart the computer afterward.
