Motorola's 4000 series radios use a "system on a chip" design. This means that all of the FCC and Qualcomm requirements for the design and manufacture of the units are combined into the chip. The chip in the radio has all of the features required for the desired application. The OEM adds the hardware specific interface and WXS drivers needed to be configured for the use and purpose of the radio.
Motorola and the OEM will tell you that the hardware specific interface need to be used to achieve the design and purpose of the radio. We do not place any restrictions or other limitations on this. Therefore, if there is an older Motorola PR 4200 radio in your possession, it will work with any Model 400 series radio. We have 100 and 200 series radios running with over 400 of the Operating Systems with the appropriate hardware specific interface and WXS drivers needed to be configured for the use and purpose of the radio. The hardware specific interface and WXS drivers are fully supported. You may want to verify the compatibility of the project and model with your radio using our website: http://www.twowayradiocenter.com/supported/products.php?search=pr%204400 We work closely with the industry and OEMS to keep up to date with the development of the software and hardware we support. What we can't support (yet ) is the use of Smartphones and other devices that connect to the Axis II port on the radio. At the moment, we are not able to provide the drivers and software for this use. However, if we had enough interest in smartphones as a technology, we could change this. We have not yet determined whether this is a viable market. Although we are dealing with high frequency related technologies, we do not have the resources to support the privacy aspects of this use.
The interface is relatively straightforward, with a few buttons and a side-by-side window that enables users to upload multiple pictures and view them side by side.The only fault I found was the copy function; if you wish to copy a specific picture or part of a picture to another one, you'd have to manually select the images and click on the copy button. d2c66b5586
