GUIDE
Q. What type of cable do I need for
RS-422/485?
A. Category 5 cable is available as Shielded
Twisted Pair (STP) as well as Unshielded
Twisted Pair (UTP) and generally exceeds
the recommendations for RS-422 making it
an excellent choice for RS-422 and RS-485
systems.
Q. How do I wire Model BB-485OP for 2-wire?
A. Make sure to externally jump TDA to RDA and
TDB to RDB.
Q. Do I have to run a Signal Ground on Model
BB-485OP?
A. Yes, all B+B SmartWorx optically isolated
devices require a Signal Ground.
