USB Port Communication The standard B-type USB port is used to connect the UPS and network server or other computer system using Liebert MultiLink. A standard B-type USB port is provided to allow connection to a computer or network server. The USB port can be used to communicate with the GXT4 configuration program (see section Configuration Program on page 38 for details) or Liebert MultiLink (see Liebert MultiLink on page 37 for description) that is provided on the CD that is included with the UPS.NOTE: Programming the output voltage of a 230V model of the GXT4 to 220V automatically derates the UPS to 96% of both the VA and watt ratings (refer to Specifications on page 53 for VA and watt ratings). NOTE: This program is compatible with UPS models beginning with ‘GXT4,’ as in ‘GXT4-3000RT230.’ It is not compatible with earlier versions of the Liebert GXT UPS. A computer running Microsoft® Windows 2000®, Windows XP®, Windows Vista®, Windows 7 or Windows 8 is required to set up and run the configuration program. 6.3 RS-232 Port The RS-232 port uses an Vertiv™ proprietary protocol that is for use with Liebert MultiLink®. This port enables a more secure connection instead of the USB cable, to the computer or server that has Liebert MultiLink installed. 6.4 Terminal Block Communication The Terminal Block includes eight pins, as shown the figure

Configuration Program

 The configuration program is on the Liebert GXT4 CD and can be used instead of making configuration setting changes from the LCD panel. The configuration program communicates to a computer running a Microsoft® Windows® operating system via the included USB cable. For most users, the factory-default settings are adequate. This section give a brief overview of the features and parameters that are available for modification, as well as the factory-default settings. Should any changes be necessary, refer to the Configuration Program User Manual that is located on the included CD for further details. The configuration program allows these features of the GXT4 to be changed: • Change and set the display language • Enable/Disable Auto-Restart (default is Enable) • Select frequency converter operation with a fixed output frequency of 50 Hz or 60 Hz, bypass disabled (default is Auto-Select with bypass enabled) • Set the Low Battery Warning alarm time from 2 to 30 minutes (default is 2 minutes) • Enable/Disable the Auto-Battery test (default is Enable) • Enable/Disable Auto-Restart after removing Remote shutdown (default is Disable) • Set the wiring mode of Remote shutdown (default is normally open) • Set the Auto-Enable output after remote shutdown (default is Disable) • Set the Auto-Battery test to 8, 12, 16, 20, or 26 weeks (default is 8 weeks) • Select the number of external battery cabinets connected to the UPS to adjust the remaining run time calculated by Vertiv™ software products (default is zero) • Select one of multiple output voltages to match various voltages.
