10.3.2 IEEE488.2
This interface is also known as IEC625 bus or GPIB. By it you can implement the LMG into
an existing bus system.
The IEEE interface can just be used for remote control, not for logging. The maximum data
transfer is about 1 Mbytes per second. This and the connection of several other devices makes
this bus a standard for complex measuring systems
This port has the pinout defined in the standard IEEE488. You can use the standard cables.
10.3.3 Parallel Port
Whenever you want to print out data directly, this interface is used. In the LMG we have
implemented drivers for the most popular printers. They are just needed, if you want to print
out graphics.
Like with the serial interface you can print out cyclic values as tables.
Printers are not the fastest devices, so it can happen, that the printer gets more data than it can
handle. In this case the printing is interrupted
This port has the same pinout like a PC parallel port. You can use the same cables.
