RS232 interface
The RS232 interface is one way to connect the unit to a PC or a microcontroller with RS232 interface. All TMCL™
commands can be sent to the unit via this interface. A null modem cable has to be used to connect the TMCM-610
to a PC.
The following connections have to be made:
TMCM-610 pin PC pin

The pin assignments of the RS232 socket of the TMCM-610 are as follows:
Pin number Signal name

5
GND
All the other pins of this connector are not connected.
4.2.6
USB interface
The USB interface is also a way to connect the unit to a PC, when higher communication speed is needed. The
interface supports the USB 2.0 standard. Please see chapter 6.5 on how to install the device driver that is needed
to communicate with the TMCM-610 via USB.
The USB interface and the RS232 interface should not be used simultaneously.
4.2.7
General purpose I/Os
The general purpose I/O connector provides eight digital outputs and eight inputs that can either be used as
digital or as analog inputs with 10 bit accuracy (thus there are no pull-ups). All digital inputs and outputs operate
at TTL level, so the maximum voltage is 5V. The maximum current of each digital output is 20mA.
The pin assignments of the connector are as follows:
