Industrial Gaussmeter IGM11 Operating Instructions
Chapter 9 Serial Interfaces
The IGM11 checks the following:
If the IGM detects an error, the telegram will be refused and not answered. The error
will be stored in the error queue and can be read out via the set-up menu or through
SCPI-command via another interface.

9.4.7 Data Content

The data content will be processed like a normal SCPI command.

9.4.8 Parameter Settings

Operating mode, device address and bit rate are set in the set-up menu. The transfer
rate of the data can be selected within 1200 to 38400 bit/s. The device address (bus
address) can be within 0 and 31. The character parity is set to EVEN for this interface
and cannot be modified.
To select the bus protocol in the set-up menu, choose the parameter value BUS.
Alternatively, the interface can also be operated in the mode P2P. Here, the interface
acts analogous to the normal EIA-232 interface.
9.5 EIA-485 Point-to-Point (P2P) Connection
In this operating mode, the interface acts analogous to the normal EIA-232 interface
in the SCPI mode. A telegram will be transmitted without any further frame data.
Operating mode and bit rate are set in the set-up menu. The data transfer rate can
be set within 1200 and 38400 bit/s. The device address (bus address is not relevant.
The character parity is set to EVEN for this interface and cannot be modified.
