4.1.3 Configured Router Mode
In this operating mode the L-Switch XP acts like a standard CEA-709 compatible router,
which can be configured with standard network management tools like LonMaker or
NL-220. This operating mode is compatible with any other standard CEA-709 router.
Figure 13 shows the proper DIP-switch settings for CEA-709 compatible router mode,
assuming all other DIP-switches remain in the factory default position.

Standard CEA-709 routers allow 4 different operating modes, which must be configured via
a network management tool (e.g. LonMaker): configured router, learning router, bridge and
repeater. Since the learning algorithm in the smart switch operating mode (see Section
4.1.1) is superior to the learning router mode of a standard CEA-709 router, the learning
router mode is not supported by the L-Switch XP.
Further, note that the repeater mode of the standard CEA-709 router differs from the
L-Switch XP repeater mode (see Section 4.1.2). While the L-Switch XP repeater mode is
transparent and does not require any additional configuration, the repeater mode of the
standard CEA-709 router must be configured using a network management tool and thus
requires commissioning.
4.2 Bit-Rate Auto-Detection
The L-Switch XP 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 14 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 on a per port basis via the
console menu (see Section 5.3.4). Further the console menu allows restarting the bit-rate
auto-detection on selected ports.
While the port is auto-detecting the corresponding port LED is flashing orange.
4.3 Network Buffers
The L-Switch XP can handle packets from the network with a maximum length of 256
bytes. There is no explicit limit in the network buffer counts.
