3.6.3 Serial interface board (SIB) (V.24 connection)
An additional V.24 interface is offered as an optional babyboard in the GEE12/16 module hous-
ing. Level matching and galvanic isolation of the V.24 adapter are implemented on the SIB. The
2400 baud rate cannot be changed.
Up to 4 GEE modules can be installed; up to 4 serial interface boards can therefore be operat-
ed.
