User’s manual FlexGain Plex, V2
Version 1.3 18 from 99
The choice of the clock source and the generation of clock signals is performed by
unit 21. The configuration of the operation parameters, switching between the operation
modes and control of the device status are performed:
• Locally via terminal port 31 with the help of the VT100 terminal or a personal
computer, which emulates the terminal. The software can be downloaded
though this port as well (by using the X-MODEM protocol);
• Through the local network by using the TELNET protocol. The software can
be downloaded from the local network by using the X-modem or a special
program (NETLOADER.EXE). To receive this program, which is distributed
free of charge, contact your dealer. The programming of the device is
considered in detail in the “Programming guide” section.
The device is powered with +3.3 V, +5 V, +12 V from inbuilt DC/DC converters 24,
25, 26.
The range of input voltages of the secondary power supply source varies from -38 to
-72 V. Mini-Rack devices have AC/DC converters 23 to convert 220 V AC into -48 V DC,
which is used to feed DC/DC converters.
