TOPAS E

Optical transmission module for AW HE120

Introduction

The TOPAS HE120 is an optical fiber transmission unit intended for a PANASONIC AW – HE120 camera. The special shape of the TOPAS HE120 directly fits under the camera base. The TOPAS HE120 has the same mechanical interface as the camera bottom and its base plate, allowing quick and easy upgrade of existing installations.

The module transmits the following signals:

  • 1 SDI HD IN
  • 1 PAL IN
  • 1 GENLOCK
  • 1 RS 422 bidirectional
  • 1 GP OUT
  • 1 IP 100 Mb/s

The module has three optical connector options and powering:

  • 2 SC/APC connectors, the module is powered by the DC Adapter of the AW – HE120.
  • 1 LEMO 3K or NEUTRIK OpticalCon Duo hybrid connector, the remote powering of the camera and the transmission module is done by the TOPAS receiver module.

As an option, the module can transmit two bidirectional audio signals, a microphone stereo input with remote gain setting and phantom power is also available. The audio option offers also the transmission of two GPIO.

As an option also, for local monitoring, the PAL input signal at camera can be replaced by a return HD SDI OUT channel.
