Information on the serial interface
• To connect the serial interface, the device has an M12 interface: A-coded, 5-pin, female.
• Via the serial interface, you can access the CLI of the device directly via an RS-232 connection
(115200 8N1) without assigning an IP address.
• Access to the device is also possible independent of the Ethernet ports.
• To connect the serial interface to the PC, you require a cable with an M12 plug and 9-pin D-
sub female connector. You can order the connecting cable for the serial interface as an
accessory.
• When it ships, the cover for the serial interface is secured to the housing see "Device views
(Page 24)".
