3.2 Data interface
3.2.1 Connecting the RS-485 cable
The D-SUB 9 port connects to a PROFIBUS DP network and functions as a master.
NOTE:
Observe the polarity of the RS-485 cable.
Install SUBCON-PLUS-PROFIB/90/PG/SC termination plugs (Order number 2313708) at
the furtherest ends of the PROFIBUS DP network.

Pos. Signal Description
1 – Not connected
2 – Not connected
3 B Data line (+)
4 CNTR P RTS (TTL direction control for repeaters)
5 GND Ground
6 +5 V Supply voltage for terminator resistance
7 – Not connected
8 A Data line (-)
9 CNTR N Neutral signal for active PROFIBUS cabling
3.2.2 Connecting the Ethernet cable
The GW PN/DP 1E/1DB9 has an Ethernet interface on the front in RJ45 format, to which
only twisted-pair cables with an impedance of 100

can be connected. The data
transmission rate is either 10 or 100 Mbps. The GW PN/DP 1E/1DB9 supports the auto
negotiation function for automatic selection of the transmission speed, as well as an
automatic crossover feature for the selection of line or crossover cabling.
Push the Ethernet cable with the crimped RJ45 connector into the GW PN/DP 1E/1DB9 until
it engages with a click.
