Input voltage: DC 9-30 V
Buffer: 512 bytes
Transmission distance: 1200 m
Masters supported: 2
Isolation: opto-isolation between master and slave
Baud rate: 1200-115200, configurable
Port protection: ESD and lightning surge protection
Data format: configurable data bits and parity
The LK-RS3201IS 2-master buffered isolated RS485 hub connects two RS485 master devices to one or more RS485 slave devices. It removes the bus conflicts that occur when two masters talk to the slaves at the same time: data requested by master 1 is returned only to master 1, never to master 2, and likewise data requested by master 2 is returned only to master 2.

Isolation: opto-isolation between master and slave
Data format: configurable data bits and parity
Extra features: configurable master port priority
Port protection: ESD and lightning surge protection
Baud rate: 1200-115200 (set independently for every port)
The LK-RS4201 2-master fully isolated buffered RS485 hub connects two RS485 masters to one or more RS485 slaves. It queues the masters automatically and forwards their data without user intervention.
