Click the button transfer the parameters.
The required resistors are already the regulator and are switched and off through
a relay. this case, the right E-LAN, for
example, used input for the signal.

0 Baud:
The transfer rate can set for each segment. The left E-LAN sends the signal through 4-wire
connection the next device that connected the E-LAN.Page Detailed description REG-DP/ REG-DPA parameters
We take care it. Meaningful speeds are:
– 500
– 125 000
0 Terminated:
If regulator the beginning end bus segment, the bus must be
closed/terminated that point with resistor (wave impedance). important
that the bus both devices terminated the beginning and the end the network. This wiring enables the
regulator function repeater.3 can bridged.
All the bus segments have terminated for 4-wire connections.
– Four-wire
A 2-wire connection sufficient for short connections (within substation, m).
The 'Terminated' parameter should set for all the devices in-between. AA: Sends the parameters the connected
device.
For 2-wire connections, termination depends the bus structure: select YES (for
closed/terminated) (for not closed/not terminated).2.5 E-LAN (bus connection between several devices)
