3.2.1 Communication
The data transfer from the base instrument (weighing point) to the remote display occurs
via remote display telegram via the serial interface of the basic unit.
The speed is set in the base unit and can fall between 2400 and 19200 baud.
Data transfer is possible at 7 data bits, 1 parity bit (straight parity), 1 start bit and 1 stop bit.
If this data format including correct parity is not maintained, the complete data telegram
is considered not received and shown on the remote display as dashes (------).
This applies when
- the set baud of the base unit is not consistent with that of the remote display.
- new data is not continually received.
- the data line is disconnected.
The data telegrams for tare and net are only present for certain functions; the gross
telegram however, is always available in normal scale operation.
The test number is transferred during test operation. It is also displayed on the remote
display as long as it appears on the display of the base unit. For marking purposes, the
dimension sign (g, kg, t or lb) is switched of.
An intrinsically safely fed remote display connected to multiple indicators must be run in
token mode. The token telegram coordinates operations.
