UMP (Unified Media Platform)

15.1 UMP Remote Controls


The UMP devices can be controlled via the network with generic applications such as a Telnet client or a web browser, though for media playback, the regular remote control types are recommended. Remote controls are separated into three different product lines as follows:





The regular iR remote control with a serial receiver unit. This is the most commonly used way to operate the UMP if you do not have a mouse and keyboard connected. The last two digits of the model number indicate the product revision. The UMP-R-100 is the baseline model; future models will use a higher number in the 1XX range.





The UMP-R-2XX series of remote controls are generic USB HIDs that are supported on the UMP as well as any other platform or operating system that supports generic HIDs. The UMP-R-2XX cannot operate all functions of the UMP and is therefore not recommended as the only remote control facility.





The UMP-R-3XX series of controls are composed of a regular USB wireless mice and keyboards, allowing them to be used with almost any other computer, and without any visible component such as an iR receiver. Note that the keyboard itself can perform almost any action in the OSD or Desktop Mode, though it does not support a Mouse Mode, like the UMP-R-1XX.



All remote controls should be connected before powering on the device, though both the serial and the USB ports support hotplugging. Due to the nature of the PS/2 port handling, an input device may be disconnected and reconnected to the device, though for this to work, a PS/2 device must be connected when the device is started

15.2 UMP Power Supplies


Depending on the intended usage, you may determine that the default 60 Watt AC adapter may be insufficient to power your device(s). In such cases, it is advisable to use the UMP-AC-130U or another more powerful model. The internal DC/DC converter board in the device has a maximum power handling of 90 Watts for the internal components, including USB bus power, though the AC adapter may exceed this value to accommodate additional USB power or peak loads.


There are two main types of AC adapter for the UMP devices. The first type is the default line of CWT adapters with no extended functionality and a green input power indication LED. The second type are the Konig AC adapters which feature a red input power indicator LED and in some cases a USB connection which allows you to power external harddisks or the UMP-SA-1XX series of signal adapters.


See chapter 1, section 1 for more information on the connection of the AC adapter and the other related components.


Due to the commonly used 12V power interface on the UMP, you can also power it from a car cigarette lighter plug. Although PelNet does not offer any accessories for this task there are 12V adapters that will fulfill this purpose.



Verify that your vehicle provides a 12V power source, or the adapter you are using has a 12V output BEFORE connecting the UMP, as the connection to a higher voltage circuit can cause irreparable damage! Note that some larger automotives provide a 24V power circuit which can be used with a 24V to 12V adapter, though the maximum load of the circuit (Wattage) will drop by approximately 50% due to the conversion.



Note that despite the DC/DC converter board in the UMP which provides a certain tolerance for brief power fluctuations, the voltage on a vehicle’s power circuit often drops as low as 40% of the intended output when starting the engine, which in turn can cause the UMP device to shut down or restart automatically.



It is recommended to contact UMP support before connecting any power sources which are not expressly recommended or listed as compatible.

15.3 UMP Signal Adapters


Depending on the type of display device that you plan to connect to the UMP device, you may need to use a signal adapter, as the device only provides a D-SUB 15 VGA output. There are two main types of signal adapters, which are explained below.



Passive Adapters (UMP-SA-5X)


These adapters are entirely passive and do not process the signal, but simply link the default 60 Hz NTSC output from the VGA output to a Composite and S-Video female connector. The main advantage of these adapters is their simplicity, due to the fact that they require no configuration or additional power from USB. The current line of these passive adapters does not allow for the connection of an additional VGA display device, though both the S-Video and Composite outputs may be used simultaneously.



Active Adapters (UMP-SA-1XX)


The active signal adapters feature advanced configuration and can accommodate for a VGA display device while the S-Video and/or Composite outputs are in use. Due to the fact that they actively process the VGA signal, additional power must be supplied by means of a USB power cable which can be connected to the UMP itself or to the USB power outlet of the AC adapter (only present on UMP-AC-XXXU models). Alternatively, you can use a regular 5V DC power supply. Using the USB power outlet of the AC adapter has the advantage that the signal adapter doesn’t lose its settings when the UMP is powered off, unless the AC adapter itself is disconnected from the mains power outlet.


See chapter 14, section 3 for more advanced information on the configuration of the UMP-SA-100 signal adapter.
