When connecting the device to the network, the following procedures must be followed:

• Use Category 5 cabling with a characteristic impedance of 120 ohms for RS-485

networks. Category 5 cables with a characteristic impedance of 100 ohms can also

be used, but with lower performance.

• Cable manufacturers provide cables with multiple twisted pairs designed for this

type of communication (characteristic impedance is 120 ohm).

• Unused pairs within the cable must be terminated with characteristic impedance

(100 or 120 ohm) on both ends.

• AWG 24 should be considered as the minimum gauge.

• Choose one twisted pair of conductors to use for RS-485 differential connections,

other conductors should be used for Signal Ground (RS-485 GND on Weidmuller

connection).

• The RS-232 to RS-485 converter must support Sense Data to be able to switch

from Send to Receive mode.

• Check each device's cabling for ground faults before connecting to an RS-485 net-

work.

• Each device should have pin 3 of the mini-connector connected to earth ground.

After all devices are configured and connected to the RS-485 network, the baud rate

can be increased to the highest supported rate (some experimentation might be re-

quired).
