1.6 Operation
Whenever it is connected to the electricity main, the weight repeater
comes on and tests the digits and LEDs, which light up in sequence.
After this, the program number and software release are displayed.
This is followed by flashing dashes which remain on until the repeater is
connected to the serial line. If valid data are transmitted along the serial
line, they are immediately displayed. The data remain displayed for up to
5 seconds, as determined by the time-out setting. If no other signal is
transmitted to the repeater, the central segments begin to flash once this
time has elapsed.
The type of string received can either be CB (see par. 5.3.1 on page
1-23) or EXTENDED (see par. 5.3.2 on page 1-24) and
acknowledgement is automatic.
If the string is the CB type, enter the number of decimal digits using the
SETUP switch on the board (consult par. 3.4 on page 1-18). If an
EXTENDED string is received, all the information is within the string
itself and there is no need to set anything. This string also handles the
metrological indications on the front panel of the display in the automatic
mode.
The serial interface used can be either RS232 or RS422, depending on
the connection made. The repeater automatically selects the type of
interface used, checking the lines piloted.
