RS-485 Local Area Network (LAN) Connectivity
If several units need to be controlled via Ethernet or USB, they do not all
have to be connected directly to the PC or an Ethernet Switch or USB Hub.
Instead, a single unit can act as a “gateway” or “master” by connecting it to
the PC and also connecting it to the remaining units using a half-duplex RS-
485 LAN bus.
There are two RS-485 connectors that accept standard 3.5mm stereo plugs.
The two connectors are connected in parallel inside the controller. These
connections along with RS-485 cable (model 8745-RS485-CBL) facilitate
daisy-chain type hook-up to simplify the wiring between an external
computer and multiple controller units.
Read controller User’s Manual for complete details.
NOTE: Make sure RS-485 cable plug is fully inserted into controller
connector input socket.
NOTE: Install and run easy to use Picomotor Windows application
software to confirm USB, Ethernet and RS-485 LAN communication.
