CX1010-N030/40 connections

CX1010-N030/40 connections 1:

The CX1010-N030 system interface features two RS232 interfaces, COM1 and COM2 (9 pin Sub-D plug connector). If there is need for more than two serial interfaces two further RS232 interfaces, COM3 and COM4 (9 pin Sub-D plug connector) can be added to the system via the system interface CX1010-N40. The maximum baud rate on all channels is 115 kBit. The pin assignment for all interfaces is equal and described below. The interface parameter can be set in the operating system or in the PLC program.
