Hello,
I have an RGM ISIS monitoring system from a yacht with a problem. This system has 6 units to get data from sensors and a main unit (brain) to communicate with these 6 peripheral units. Communication is through optical fiber. From 6 units one is missing at computer.
I took two units (the bad one and a good one), power supply and brain to check communication at workshop.
On the peripheral units I have SFH576V as emitter and at main unit I have SFH551-1V-1 as a receiver.
When I measure at SFH576V I have data coming out but when I measure at receiver I don´t get them, only 5V. I know this peripheral unit is working properly and I have the same data (measurement) at output of the unit which is not recognized on the system.
I know the input at main unit was also working so my question is: is it possible that the cable has some problem even if I see red light at the end of the cable??? It´s only a piece of optical cable I took from the yacht.
