UtiliNet SCADA Single Board Radio 98-1546 Rev AA 7
Pin Functions
Pin Outs for the connector as described below are designed to interface with the developer’s OEM
board. When pins are connected to non developer boards or when standard interfaces are required
without use of the USB cable (P/N 19-1220), appropriate design constraints (power and logic) must
be adhered to (See “UtiliNet SBR Logic” on page 29).
