Splitter Interface

This splitter interface (Cat. No. 939) can be used if access to more than one of

the Auxiliary Receptacle functions is required simultaneously. Connecting the

interface to the 6-pin connector on the sampler provides three additional

connectors for use. Two or more interfaces may be connected in series to

allow for as many connections as desired.
