Manual Setting
Wires: A1: Blue Wire; A0: White Wire; Shield wire is Digital COMMON.
Selection Manually: Connecting the Blue wire to the shield wire: A1 = 0 or Logic Low
Disconnecting the Blue wire from the shield wire: A1 = 1 or Logic High
Connecting the White wire to the shield wire: A0 = 0 or Logic Low
Disconnecting the White wire from the shield wire: A0 = 1 or Logic High
Shield wire is Digital COMMON.
Selection Digitally: a 2-bit digital word to the gain selection inputs.
Shield wire shall be connected to Digital COMMON.

Transducer Connector Assembly

If buyer orders a free hanging, flange mount or flush mount transducer, BII assembles the connector on transducer cable. Buyer dose not need to do any assembly.
If byer orders a thru-hole mount, bolt-fastening mount or end-face mount transducer, BII ships the transducer with wire leads and the mating connector to buyer. After installing the transducer on the mounting wall, buyer shall assemble the connector with transducer cable and solder the wire leads to the connector pins. Note: the size of the mating connector is bigger than mounting hole size of the transducer.
