This chapter covers the physical and electrical installation of the Solaris™ Dome's
External Termination Unit (XTU).
NOTE
The XTU is patent pending.
The External Termination Unit (XTU) is an IP67 sealed enclosure containing the
Dome unit's power supply, telemetry interface, alarm/relay connections, video
conditioning and protocol conversion.
The advantages of this separate XTU enclosure include:
Ease of setup and installation of the Dome unit
Single connection cable to the Dome unit
All other connections are made to the XTU
Ease of access for maintenance
The XTU allows the Dome to be controlled via:
Coaxial telemetry (see Section 9.4.1: XTU connections - coaxial (C-type)
telemetry).
RS485 telemetry (see Section 9.4.2: XTU connections - RS485 (D-type)
telemetry).
Photon telemetry (see Section 9.4.3: XTU connections - Photon telemetry).
