Model 6122C, 6526LCD-C, 6702S, 6702S-LCD and 6603DT

  • Overview

    Microwire Serial to 4-20mA Interface 6122C converts a serial signal to a 4-20mA output. Any Microwire compatible 3-wire synchronous serial signal channel can be used as an input. It supports two 16-bit resolution channels.
    The Starflow, Prologger and Starlogger support MicroWire as an alternative use of the SDI-12 channel. This enables the connection of any measured channel to a 4-20mA transmitter.

    The Starflow Liquid Crystal Display Module 6526LCD-C interfaces with the 6526 Starflow ultrasonic Doppler velocity, depth and flow Instrument. It displays the values obtained from the most recent scan.

    The Starflow’s scheme defines which parameters will be displayed. For example, one of the supplied schemes displays water temperature, battery supply voltage, totalised flow and logging status.

    The 6526 LCD is packaged in a compact weatherproof polycarbonate enclosure, fitted with pre-wired SQL type
    connectors. These connectors enable direct connection to a Starflow instrument, and computer/external power supply using a 6603D-SDI cable.

    The SQL connections are designed to be ‘pass through’ so that the computer can connect to the instrument without disconnecting the power or display.

    The display module power supply can be wired to a user-installed switch so that it can be switched on only when necessary. The module display is refreshed every scan (normally 15 seconds with a Starflow) and will display a
    test message when power is applied until a message from the instrument is received. Pressing the button on the front panel resets the display.

    The 6702S weatherproof polycarbonate enclosure contains mounting hardware for a 12V 14Ah Sealed Lead-Acid Battery (6907B-14) and Drying Tube (6603DT).

    There are three SQL connectors mounted in the base of the cabinet. These are wired to enable connection to the Starflow, computer and solar panel/external power

    The 6702S-LCD has an LCD mounted on the hinged lid of a large weatherproof polycarbonate enclosure. It displays the values of parameters obtained from the most recent scan.
    The LCD unit communicates with the Starflow via the HSIO bus. The RS232 interface is available for other purposes such as connecting a modem.

    The Starflow’s scheme defines which parameters will be displayed. For example, one of the supplied schemes displays water temperature, battery supply voltage, totalised flow and logging status.

    To keep the vent tube in vented cable dry, a Drying Tube 6603DT containing “Silica-Gel” desiccant is connected to the cable. The Drying Tube needs to vent to the atmosphere. Replace Drying Tube when it turns pink.

    Use this model with the Starflow and Water Depth Probes (Model 6542D).
