The alarm input also is a digital input with TTL level and an internal pull-up resistor (the other inputs do not have
internal pull-up resistors as it would not be possible to use them as analog inputs then). The functionality of this
input can be configured (please see the TMCL™ Firmware Manual for details).
Pin 1 of the connector is shown in
Figure 4.2. The pins with odd numbers are those near to the edge of the
board.

Reset button
Pressing the reset button resets the microcontroller. All motors are then stopped immediately and everything is re-
initialized.

ISP connector – restore to factory default
This connector is used for two purposes:
Programming the CPU via an in-circuit programmer.
This is to be done by TRINAMIC only and not by the user!
The user can upgrade the firmware via the RS232 or USB interface using the
Install OS
function in the TMCL-
IDE.
Restoring all parameters to their factory default values: Nearly all parameters can be stored in the EEPROM of
the CPU. If some parameters have been set wrongly this can lead to a case of miss-configuration where the
module cannot be reached by a PC any more. In such circumstances, all parameters can be reset to their
factory default values by doing the following:
1.
Turn OFF the power.
2.
Link the pins 1 and 3 of the ISP connector with a jumper (as shown in Figure 4.6).
3.
Turn ON the power and wait until the
Activity
LED flashes fast (much faster than normal).
4.
Turn OFF the power.
5.
Remove the link between the pins 1 and 3 of the ISP connector.
6.
Turn ON the power and wait until the LED flashes normally (this can take some seconds).
Now, all parameters are restored to their factory default values, and the unit should work normally again.
