2 UIMtp PRODUCT DESCRIPTION The Apricum USB interface UIMtp connects a PC to KNX TP via USB and provides a galvanic isolated bi-directional data connection to the KNX bus. With the ETS or another KNX compatible commissioning tool the UIMtp works as programming interface. Due to HID profile support no specific USB driver is required. The UIMtp also supports the USB suspend mode. The UIMtp establishes access to all bus devices to feature commissioning, addressing, setting parameters, visualization, protocolling, and diagnostic operation. The protocol used for communication between interface and host is the flexible cemi protocol. The connection between KNX and a PC with standard software (like ETS, EITT, also in Raw Frame operating mode) or other software is handled by the FALCON driver. The UIMtp supports long messages (up to 220 byte APDU length) and ensures easy software handling also under operating systems not supported by the FALCON driver (e.g.: Linux). For specific diagnostic applications like EITT the UIMtp supports the "Raw Frame" operating mode. The UIMtp is supplied by both KNX TP and USB. So, no additional external power supply is necessary. Two LEDs are located on the front panel as illustrated below. The LEDs indicate details concerning the bus (connection) state and telegram traffic.

3 OPERATIONAL DESCRIPTION After connecting the UIMtp to the PC the LEDs show the bus connections status. Lightning green means a connection is established. Blinking green indicates the telegram traffic extent. In Microsoft Windows the UIMtp is recognized as HID (Human Interface Device). So, no extra drivers have to be installed or downloaded. In general, network configurations become less time-consuming. The UIMtp s ETS database entries are available for ETS3.0d and upward. The device (dummy application without parameters and without communication objects) can be added to an ETS project as usual. Picture 2: Connection diagram 3.1 CURRENT INTERFACE OF ETS BUS CONNECTION To use the UIMtp as the KNX programming interface in the ETS the UIMtp has to be chosen as the Current Interface. This can be done in the ETS Bus Connections tab and when editing a project, at the bottom line ( Name and state of current connection ) of the ETS window.

3.2 PHYSICAL ADDRESS ASSIGNMENT The device is supplied with the individual physical address 0.2.255. With the ETS the physical address can be assigned to the device by setting the desired address in the Bus Connections window of the ETS. To download the desired physical address the UIMtp has to be chosen as the Current Interface. Then type in the Individual Address and press the Test button. Note: In this document only the term physical address is used. The term physical address means the physical address as well as the individual address. Both terms are used interchangeably by the KNX organisation. 3.3 ETS PRODUCT DATABASE The KNX product database entry (only as ETS dummy application) can be downloaded from our website and the KNX Online Catalog.
