    9.4. Cabling The SPCe functions as a DTE (Data Terminal Equipment) device. When the controller is connected to another DTE device (such as a personal computer), a null modem serial cable is required to connect the devices. The null modem cable swaps the signal and control lines so that receive and transmit are properly connected.
