Edwards nEXT nEXT85 - Logic Interface Connector

3.9 Logic interface connector
The pump has a 15‑way logic interface connector at the end of the logic interface cable.
Use an applicable connector mang half (not supplied) to connect the nEXT pump to the
customer equipment. Refer to the table that follows for the connector mang half type.
