Figure 141: RS-485 Network Termination.
The L-IP supports bit-rate auto-detection on RS-485 channels. The factory default DIP-
switch setting enables bit-rate auto-detection on all RS-485 ports. Figure 142 shows the
DIP-switch settings to disable bit-rate auto-detection, assuming all other DIP switches
remain in the factory default position.

Alternatively the bit-rate auto-detection can be enabled/disabled via the console menu (see
Section 5.5). Further the console menu allows restarting the bit-rate auto-detection on
selected ports. While the port is auto-detecting the activity LED is flashing orange.
11.4 Redundant Ethernet
11.4.1 Ethernet Cabling Options
The L-IP series “C” models are equipped with two Ethernet ports, which are connected to
an internal Ethernet switch. This allows for advanced cabling options to reduce cabling
costs or to increase network resilience. For this discussion, the term
upstream
is used to
designate the direction towards the network, which the devices are connected to. Likewise,
the term
downstream
is used to designate devices more distant to the network which the
devices are connected to.
