5.5 Connections for RS485 Interface
The RS485-mode allows for configuration of motor parameters as well as remote control of the motor.
5.5.1 Interface installation
To connect the module to a PC a RS485 interface is required, for example TRINAMIC’s new USB-2-
485 or any other RS485 adapter, like the standard RS232 to RS485-converters. Input A has to be
connected to RS485A of the IDX and Input B with RS485B.
5.5.2 Control with terminal program
Having installed the hardware, the IDX can be controlled with any terminal program, like
HyperTerminal that comes with MS-Windows. Following steps are described for HyperTerminal but
are similar for the other terminal programs:
Type into the terminal window commands like “AV 50000”, “AA 300” or “Ac” and execute each with
ENTER. Pay attention to the spaces between command and value. With standard RS485 adapters the
typed value may be echoed and lines like AAVV 5500000000 for the typed AV 50000 appear. If this
happens best is to pay no attention to the screen and just type in the commands and press ENTER.
The value sent to the module is only the typed and not the displayed. First command to the module
should be an acceleration differing from 0 to enable RS485 mode. If this value is stored to the
EEPROM step/direction control is not possible until acceleration is set to zero again (and eventually
stored) or the board is reset to factory default.
