Note: In case of use in RACS 4 system, the UT-4DR requires PR Master software in version 4.4.6 or newer. Note: It is not possible to use UT-4DR interface as a virtual serial port so it cannot be used for firmware upgrade of PR series controllers connected to RS485 bus.
Fig.1 Typical connection diagram for UT-4DR interface 3.2 Front panel According to fig. 2, the UT-4DR interface is equipped with LED indicators on front panel to indicate various states of the device and with RESET button to restart the controller in the same way as in case of powering device off and then on.
Note: The operation of UT-4DR in dedicated LAN is guaranteed by Roger. Practical tests proved that the interface can be also used in LAN, where multiple systems are operated as well as in WAN but in such case UT-4DR functioning is not guaranteed by Roger due to number of possible and unpredictable network conditions.

Additionally in the field Interface it is possible to select if the interface is operated in LAN or WAN which results in different levels of acceptable communication delays.
Each UT-4DR interface must have individual IP address but they can use the same TCP port. 4.3 Configuration with Telnet In order to log in to the UT-4DR, please type in the command line: telnet <device IP address>, e.g. telnet 192.168.0.38. Then please log in as a default user (user: root, password: dbps). Then after entering help command, a list of available commands shall be displayed.
