ComBricks Alternative Cable Repeater Module The SCOPE alternative cable repeater (SALT) allows PROFIBUS communication over non-standard cable. The user can easily verify bus signals with the built in oscilloscope, which is accessible through the web server. This product is an excellent tool to modulate PROFIBUS signals on non-standard infrastructures and is the only available PROFIBUS repeater capable of fixing EMC problems. This allows technicians to efficiently maintain the PROFIBUS installation and optimise the entire life cycle of the installation. This product can also be used to increase the idle line voltage on segments where interference causes communication disturbances. The large connectors allow specialty cable and more cable stress. The repeater channel and the integrated oscilloscope are directly connected with the ProfiTrace OE core in the Head Station. The data traffic is constantly monitored for glitches which are digitally filtered out. Two Rotary switches manipulate the values of the termination network. The combination of both set the impedance and the level of the idle voltage. At the other end of the cable, another SALT repeater or the T1-PEPPER has to be placed.
