Mere information

The Fiber Converter is a clickable module for the modular imc ARGUSfit system. It allows decentralized distributed system topologies.

The module converts the internal high-speed ARGUS system bus, which connects the ARGUS measurement amplifiers and interface modules via the click connector, to a fiber-optic data link in the sense of a media converter. Thus, the click connection can be extended to a spatially distributed arrangement of the entire ARGUS system by a pair of converters (base/remote satellite) and a fiber optic cable.

The Satellite block uses a joint power supply that is fed into the remote fiber converter module.

imc ARGUSfit: Flexible modular platform for fast measurement systems

Based on an imc ARGUSfit base unit, imc ARGUSfit measurement amplifier and interface modules can be combined to form complete systems by means of a robust click mechanism, which can even integrate
imc CANSASfit modules. The click connectors provide the electrical connection to the power supply and system bus.

For expansion to decentralized distributed topologies, the fast internal ARGFT system bus can be converted to fiber optic cables by means of a clickable fiber converter module.

The entire system can be controlled via a common Ethernet connection (LAN/WLAN) with a PC (imc STUDIO software) and can be networked and operated synchronously and uniformly with all other imc data acquisition instrument series. Furthermore, it can also be operated autonomously and stand-alone without PC with data storage on microSD.

 


 

Fiber converter application

One fiber converter each is clicked onto both sides of the remote fiber connection. There must be at least one ARGFT module between two converters. A star-shaped arrangement is not permitted. The converters have a uniform design and recognize their function (in/out) automatically:

The voltage supply of the base block is realized via the supply socket of the base unit. The power supply of the Satellite block (ARGFT Satellite block #1) and possibly further Satellite blocks #2..n is realized via the supply socket of the fiber converters clicked onto these Satellite blocks. For this purpose, a DC supply voltage or an AC/DC adaptor must be connected to the LEMO.0B (2-pin) "POWER" socket.

If the remote fiber converter detects no signal activity via the connected fiber cable, it deactivates the power supply of the clicked modules and enters in sleep mode with reduced power consumption. If signal activity is detected, the power supply for the clicked modules is activated. Thus, switching off the base unit always leads to switching off the Satellite blocks as well, and the slave fiber converters are put into sleep mode.
