RS485
The
SW-D8000U
can have up to 15 optional remote keyboards controlling it through the RS-485
network. In addition, a single remote keyboard can control up to 15 different
SW-D8000U
units, (or
a mixture of keyboards and multiplexers totaling 16 devices), installed in a multi-drop configuration.
The
SW-D8000U
unit address on the RS-485 network is programmable in the RS-485 section of the
COMMUNICATIONS submenu. You need set the address of the multiplexer on the network 1-15.
Using RS-485 correctly wired, the total length of all connections on one configuration of multiple
units and multiple keyboards can be up to 3,200 feet (1,000 meters) from end to end. A remote
keyboard can thus be up to 1,000 meters from the actual unit without the need for additional
transmission equipment.
