5. Communication with the controller
The communication works with a PC. Three configurations are possible: either a single-axis configuration, or
a multi-axis one with DSMAX or DSTEB, or a multi-axis one with micro-master.
5.1 Single-axis configuration
In this configuration, the PC and the controller are linked through the ETEL-Bus-Lite2 (EBL2) protocol (serial
communication) whose default communication speed is 115'200 bps.
This protocol is open. Refer to the 'EBL2 Communication Manual' for more information.
5.1.1 Baud rate configuration
The baud rate of the serial communication (EBL2) can be modified with parameter K195.
Remark: On the DSCDM, parameter K195 must be saved with the same value on both axes.
5.2 Multi-axis configuration with DSMAX or DSTEB
In this configuration, the controllers are linked in daisy-chain. The master is a DSMAX or a DSTEB motion
controller, with whom the PC communicates via the PC ISA or PCI connector. The axes are called slaves. All
axes are linked together by the Turbo-ETEL-Bus also called TEB (ETEL proprietary protocol). One of the roles
of the master is to dispatch the orders he receives from the PC or (sent by itself) to the slaves. Each axis has
a personal number, and if several axes are chained, every number must be different from the others (from 0 to
30); the master will always have the number 31. It is then possible to link up to 31 axes.

K Function Value Comment
K195
Enables the selection of the ETEL-Bus-Lite2 rate. It is taken into account
only at the first switch on. If the user wants to change it, the value must
be set in parameter K195, saved into the controller with SAV.<axis>=2
and then the controller must be switched off and on.
