LegacyBox (connections)
Connection of a LegacyBox is required whenever legacy BUCHI laboratory equip-
ment is to be controlled via the Interface I-300 Pro. The LegacyBox is connected to
the distillation system using a standard BUCHI communication cable and has other
connection options such as an RS-485 communication port. There is also the option
of incorporating pumps of other makes in the Rotavapor system and controlling them
via the interface. In that case, the pump requires a 0 – 10 V input.
The LegacyBox is fixed to a Rotavapor R-300 or a laboratory stand clamp.
