NOTE: Multiple PLCs/Devices can be connected to Port 2 of a DN-3000 if:

1)All PLCs/Devices use the same protocol.

2)Each PLC/Device can be internally addressed with a network address.

3)Each PLC/Device can communicate on a RS-485/422 multi-drop communications network; -OR- RS232 to RS485 converters (1 per PLC or Device) are used;

-OR- a 3rd Party multi-port communications expansion module (Port Expander) is used.
