Adjustments in the SCI Mode
SCI OFF
: At this adjustment a transfer of measured values from the GM 80 is disabled.
The GM 80 can be controlled however with the GM 80-commands.
HAND
: In this mode a measured value is issued via the serial interface when the Enter key is pressed at the GM 80.
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 written in the logger. Since the trigger pulses may occur in
10ms raster and additional time-logg is not possible. The flank of the trigger pulse must be on HIGH for at least 4ms. Then it
must be on LOW for at least 6ms.
TRIGGER2:
This mode functions like the trigger mode, however here the MIN value and the MAX value
are set back at a recognized trigger pulse. The display is set back to the display mode which was adjusted in
menu 2.9 INPUT-DISPLAY.
Connection to the Serial Interface
As a single device, the GM 80 can directly be connected to a PC by a serial 1:1 connecting cable.
By internal circuitry, up to 6 devices can be connected to the RS232 interface parallel.
The connection with the GM 80 takes place parallel via a 1:1 connection (Rx on Rx, Tx on Tx and GND on GND). The
connection to the pc then takes place with a zero-modem cable. In the BUS operation mode all GM 80 units operate as
SLAVE; a connected control as MASTER.
