FlexGain PLEX - 1.2 Features

User’s manual FlexGain Plex, V2
Version 1.3 14 from 99
• Mini-Rack – a unit to be inserted into a 19’’ cabinet;
• Stand Alone – a unit to be mounted on a horizontal surface.
These modular designs allow one to change and expand the functionality of the
devices by installing additional daughter boards without changing its hardware, i.e., the
basic module. The shelf with the Sub-Rack multiplexer installed in it as well as Stand Alone
multiplexers are powered from a grounded primary DC source (–48 V). The Mini-Rack
multiplexer can be powered either from a grounded primary DC source (–48 V) or and AC
source (220 V).
