1.4.2
Interfaces
The SONOCOOL ultrasonic bath features two interfaces on its rear side which may be
optionally used by the operator.
Note:
Implementation of the technical programs required for communication is the responsibility
of the operator and is not supported by the manufacturer. The manufacturer only
guarantees the proper functioning of the interfaces.
Commercially-available cables may be used for the communication.
It is possible to use both interfaces simultaneously.
1.4.2.1 D-Sub 15 - Pinning
15-pin D-Sub interface for remote control, e.g. using an CLP.
