If you can still reach the module via RS232 the easiest way will be to click the "Reset to factory default" button on the "Others" tab of the "Configure module" dialogue in the TMCL-IDE.
If the module can not be reached by the serial interface any more you can try to connect together the pins LED_TEMP and DIRIN. If the module has at least firmware revision 1.08 it will then be reset to factory default settings then (connect the two pins togehter, switch on the power supply, wait some seconds, switch off, remove the link, switch on again). If this does not help we will have to reprogram the module here.
