RS485 hub/repeater

2.
DMXH1003C is a divisional hub for RS485 bus ,which designed for the system
requirements of RS485 bus under complex environment, through the series of
products, a topology can be made from RS485 bus network into star shaped network
or tree shaped network, which provides simple and reliable solutions for complex
RS485 network.Besides can separately for each road RS485, baud rate, data bits,
stop bits, parity, various RS485 can be configured to different communication
speed, can also configure RS485 master-slave direction, RS485 master-slave
direction is not fixed, can be configured to 1master device have 2 salve unit, two
master device 1 salve unit .
There are a variety of product specifications including 3 channels as well as
with optical isolation for the users to choose.
