Overview
FR CUBE can work with no connection to a PC (standalone mode).
In standalone mode, the instrument is controlled through a low-level
connection interface.
Signals
Signals needed to control the instrument in standalone mode are located
in the “Low-Level Interface” connector (see “Connectors” on page 59 for
the connector pinout on the various FR CUBE models) and are explained
below.
Signal level is 0-5V. All lines are isolated (referenced to GNDI).

START line (input): Executes the project specified by
PRJ_SELx lines on the programming
site(s) enabled by START_ENAx lines.

Active high.
PASS/FAULTx lines (output): Valid at the end of project execution (when
BUSY is low). Indicate, for each programming
site(s), the success state of the programming
project. (OK = high, ERR = low).
