The LIM-AC (

AC
) connects a 2 way radio station to its operator device via lea-
sed line. It is certificated according to german TBR 15 and for this can be connected to private and
public/leased lines.
The 2 wire connection is plugged into the connector Line. The operator device is connected to the
plug named Major. The connection LIM-AC to the Major operator device is established through a one
-to-one cable. Standard network patch cords can be used.
On the opposit side the devices FT634a, FT634aC or FT633AC can be used.
All operator devices of the Major series (e.g. Major 4a, 5a, 6) can be directly connected to the LIM-
AC.
Exception:
The Major BOS 4 and Major BOS 8 feature a busy line instead of the 12V power supply on the 8 pole
plug. In this case the LIM-AC has to be powered via the separate power supply plug.
