For the connection of ccTalk devices to a PC you need an electronic interface that suits the
voltage to be used in this serial communication. There are two available interfaces, one with a
USB connection and the other with a RS-232 connection, to be connected to a COM.
6.2.2 ccTalk interfaces
6.2.2.1 Interface USB – ccTalk.
This interface is connected through the USB port of the PC and provides ccTalk to the bus.
This connection can be connected to any ccTalk device available with a 2 x 5 - way flat
ribbon connector. This interface eliminates the echo of the ccTalk communication.

It is necessary to connect a power supply source of 12/24VdC for supplying voltage to the
bus and the installation of the drivers that come with the device so that it is recognized by the
operating system.
6.2.2.2 Interface RS232 – ccTalk.
This interface creates a ccTalk bus through a serial port of the PC (COM port). This interface
does not have of the necessary electronics to eliminate of the echo of the bus, so it receives the
commands sent.
