Hi!
Thanks you all in advance.
I search on the web about which cable should I use to connect 5 gas meter to a Mgate device through RS-485 connection. Distance should be less than 300 ft (100 m) between the Mgate device to the last meter.
Some folks recommend STP Cat6, others Belden 3106A.
I currently have the following cables:
1- Belden 9941
2- Belden 9322
3- Belden 9463
4- Honeywell 12065509
5- STP Cat6
Which of those cables should be my best choice?
I am also read about to add a resistor of 120 ohm in the Mgate RS-485 connector and in the RS-485 connector of the last meter. My questions about this:
No matter what cable I chose do I always have to add the resistor at the end of both ends?
Thank everyone for your help.
