How to Interface the LARC

The LARC 1 connector interfaces the mainframe to the
Lexicon Alphanumeric Remote Control (LARC) via a
flexible 50-ft cable (supplied). If your system is
equipped with a single LARC, this is the connector you
should use.
The LARC 2 connector has two functions. It allows
connection of a second LARC to the mainframe for
applications where use of two LARCs is required. It can
also be used to connect the 480L to a 224XL with both
units under the control of a single LARC. A 10' cable is
available from Lexicon for this connection. (Lexicon
