3.3 Connecting the Module
The TMCM-109 module consists of two PCBs: the CPU board and the base board. All the connectors
can be found on the base board. They are shown in Figure 3.4.
Attention: Never plug in the board in reverse direction!

3.3.1 Connector 1: Power Supply, RS485, Step/Direction
Use this connector to connect the module to the power supply. The connector also provides pins for
RS485 and Step/Direction signals. To use the RS485 interface, it has to be enabled via the interface
selection input (please see connector 2 pinning). The polarity of the shutdown input can be
configured using TMCL (please see the TMCL Reference and Programming Manual for details). Please
note that the shutdown input, the step input and the direction input are connected to photo
couplers. The ground line of all three photo couplers is connected to terminal 5.
