7.1.1. Ethernet adapter Overview


The 8SMC4-USB-Eth adapter has been renamed 8Eth1 [1]. All available instructions in our manual are relevant and applicable to both devices. General information


Outward appearance of 8Eth1 adapter

8Eth1 [1] is a universal device based on Cubieboard2 single-board computer with OS Linux inside, which enables the end user to interact with motor controllers remotely via various Ethernet-oriented interfaces. This device is also intended to be a universal provider for different services related to controllers’ popular usage scenarios (e.g. motion control). It means that if there is a standalone program which could be effectively used in conjunction with our controllers, chances are high that this adapter already has it preconfigured and all you need is to plug some controllers and connect Ethernet cable to it. Out-of-the-box 8Eth1 supports online web-camera streaming, LAN auto-discovery system and two interfaces to configure and control motor controllers:

  1. TANGO control system interface.
  2. XIMC interface (compatible with XiLab and libximc).

Moreover 8Eth1 is equipped with embedded web-based administration interface, which enables the end user to conveniently control the device and monitor its state.

Using a USB hub, you can connect 36 controllers to this Ethernet adapter.
IMPORTANT: For a USB connection, it is better to use a tree structure. The fewer USB hubs you use, the better.


The work with the multi-axis controller of 8SMC5-ETHERNET/RS232-B19 via Ethernet does not differ from the work with an 8Eth1 adapter

Industrial motion controller/driver 8SMC4-ETHERNET/RS232-B19 is designed especially to control up to 12 mechatronic systems based on standard DC, Servo or Stepper technologies. Controller/driver housing can be mounted in standard 19 inch industrial cabinets. Several boxes can be connected in a single network via Ethernet port. System can be automatically set on a peer-to-peer mode without any special infrastructure or master servers to operate. Also each axis could be controlled via separate RS232 port.

8SMC4-ETHERNET/RS232-B19 contains all necessary subsystems, including: control, power units and etc., which support the simultaneous work of all axes. Controller/driver can be connected to a number of PC-based workstations via Ethernet. All users have access to the range setting of the available axes and assignment of access privileges. From the programmer’s point of view, working with all axes of the system is very similar to working with a simple 8SMC4-USB box. The number of the axes available for a user and processed by the system can reach 50000. Front panel contains LED power and status indicators, manual buttons, system interlock button and Ethernet port. On the back panel there are motor connectors and separate RS232 ports for each axis, synchronization I/O connectors, a power connector and on/off button.The system is cooled through grille slots in upside and underside walls of the box.
