Strip Cable
Similar to Shown
Use ProfiBus cable
per DIN 19245 and
EN 50170.
Do not mix RS485 A & B connections. Green wire is A, red wire is B.
You MUST terminate the network at both ends only.
Termination resistors are integrated in the ProfiBus connector.
When you switch termination ON, the out-going connections
are disconnected from the network.
Network Length
Use Type A ProfiBus cable per EN 50170. Keep line lengths less than the
length indicated below for your transmission rate. For baud rates not shown,
the lower length of the closest range end points apply (i.e. 100M at 3Mbps).
Bus Segment Length Limit Per Baud Rate For Type A Bus Cable
BAUD 9.6K 19.2K 93.75K 187.5K 500K 1.5M 12M
Type A 1200M 1200M 1200M 1000M 400M 200M 100M
Termination
The network must be terminated at both ends only. Most ProfiBus
connectors include a switch for termination as shown above. Note that this
switch will also disconnect the outgoing network signal.
CONNECTIONS
Network
Use ProfiBus connectors
similar to the one shown at
right (Siemens version shown).
Always use ProfiBus cable per
DIN 19245 and EN 50170.
When building cables, do not
mix A & B connections. Green
wire is A, Red wire is B.
The connector must have built-
in inductors in order to operate
at the higher baud rates.

IMPORTANT: Do not connect
earth ground to logic Ground
(DB9 Pin 5). Earth Ground
should connect to cable Shield
(common to DB9 Pin 1).
Note that Acromag modules
also support the optional RTS
direction control signal at Pin
4.
