P25:
P25 is a digital system that is mostly used by public and private emergency
services world wide.
Currently the DV4minis have 2 reflector systems available:
●
PCS001 for Europe, located in Switzerland
●
PCS002 for the Americas, located in Florida
dPMR:
dPMR is a DMR system from China which uses a several chinese Codecs
instead of the DVSI AMBE codecs commonly used by other digital systems.
These radios are cheaper as they do not need to pay license fees for the
Codecs. Practically you have to use radios from the same manufacturer on
both ends of the communication, as they are not much standardized. This is
why we call the mode experimental.
System requirements:
The following components are necessary:
1. DV4mini USB stick
2. PC Software: DV4mini Control Panel
3. A digital radio (D-Star, DMR, C4FM, P25). If you use the DV4voice (AMBE)
you can just use a PC headset instead.
4. A PC with Windows 7, 8.1, 10; Linux on a PC or an ARM computer like a
Raspberry, BananaPi or Odroid.
5. Internet access
The DV4mini is connected through the USB interface with a PC or a single
board computer. The DV4mini control panel software has to be installed.
You can download it in the download section of our web site at
www.wirelesshold.com
Then start the control panel software and enter the settings you want to use.
If you get a message about a missing DLL download the microsoft VC
redistributable from our website (download section as well) and install this as
well.
