ST-200W & ST-200E

The ST-200W and ST-200E models feature a sturdy alumium enclosure with LED indicators on the front panel and connectors at the back.  The small size allows it to be easily mounted in vehicles and other space constrained locations.

Two variations exist for either Wi-Fi or Ethernet communications.  The Ethernet model is particularly suited to providing monitoring capabilities to proprietary wireless networks or where ethernet communications may already exist.

Examples of where the Ethernet model may be used include;

  • Proprietaty wireless solar repeater trailers (such as MotoMesh)
  • Comms huts & infrastructure locations for power monitoring, UPS activation detection and remote resets of equipment.

Where wireless access does exist the ST200W has the advantage of being able to continue to operate from the internal battery if power is disconnected.  This is a common occurrance where devices such as repeater trailers are turned off and moved or power/charging faults cause the device to go offline.  In this scenario the SiteHawk ST200W would continue to report its position and system power status allowing the trailer to be located or the power problem diagnosed and rectified.

ST-220W Outdoor Asset Management Device

The ST-220W is a variation of the ST-200W Wi-Fi model designed specifically for outdoor installation directly onto equipment.

The ST-220W is packaged in an NEMA4x weatherproof polycarbonate enclosure.  Integrated antennas for GPS and wireless communication limit the cabling requirements to a single power lead which also delivers the I/O capabilities (if required).

The ST-220W supports mounting directly to a pole (40-90mm) or can be supplied with a standoff mast if required.   The minimal cabling and flexible mounting option equates to a fast and simple installation, reducing the time and complexity of deployments.

Each unit is supplied ready to install with antennas, pole mounting kit and a 5m pre-terminated power/IO cable.
