6.3.1 MX840A pin assignment
So that insertion or removal of a transducer connection can be unmistakably identified, Pin 4
and Pin 9 in the connector plug must be bridged! If this bridge is missing, no measurement
values will be recorded at the connection!

NOTE
Many HBM transducers are fitted with 15-pin D-SUB connectors (2 rows). The adapter
cable 1-KAB416 can be used for connection to the 3 row D-SUB-15HD device
connectors of the MX840. Pins 4 and 9 are already bridged in this adapter cable (see
chapter 9.4.3).
