It is necessary to connect a power supply of 12/24VdC to supply voltage to the bus to install the
drivers that come with to the unit so that it is recognised by the operating system.
7.2.1.2 Interface RS232 – Cctalk.
This interface generates a Cctalk bus on the serial port of the PC (COM port). This interface
does not have the electronics required to the eliminate the echo of the bus, so it receives the
commands that it sends.

It is necessary power the unit with a power supply of 12 or 24VDC depending on the voltage the
elements of the bus need.
7.2.1.3 IS21 Cctalk Interface
The IS21 Cctalk interface can work autonomously as an interface of the application Cctalk
Manager. To manage the T3 hopper a RS232 – Cctalk interface is used in combination with the
application Cctalk Manager

The IS21 Cctalk interface makes a Cctalk bus using a serial port (COM) on the PC. The
