5.6 Adjustments in the SCI mode
SCI off:
With this adjustment, measured values transfer from the 7280 measuring
amplifier is disabled, but the 7280 measuring amplifier can be controlled
via the 7280 commands.
HAND:
In this mode a measured value is issued via the serial interface when
ENTER is pressed at the 7280 measuring amplifier.
AUTO:
In this mode a measured value is issued via the serial interface in the
adjusted delay.
TRIGGER:
At a trigger event in this mode, a measured value is issued via the
serial interface. The trigger pulses can occur in 10 ms raster. The flank of
the trigger pulse must be on HIGH for at least 4 ms. Then it must be
on LOW for at least 6 ms.
5.7 Transfer rate / specification RS232 (V.24) / USB
Parity:
none
Number of data bits:
8 (1 Byte)
Stop
bit:
1
Baud rate:
adjustable (2400; 4800; 9600; 19200; 38400; 115200
In the USB mode, the baud rate in the 7280 measuring amplifier
and in the connected device must match.
