C-CONTROL Connectors and Ports

Pin rows

All useful signals and ports of the computer are connected to two rows of pins, that can be directly
plugged into your application. The pictures show the top view (the pins are located at the opposite
side).

Interface Connector

Even if all useful signals are available at the pin rows, the
serial and IIC-Bus interface is available at a seperate
connector for easy plug and play use (protected against
reverse polarity and supplying the operating voltage)).
.

Jumpers

The C-Control Computer has to jumpers: AUTOSTART and UREF

Autostart:

JP2 at Unit M2.0
JP9 at Unit M1.2
If this jumper is attached the user program stored in the memory will be started when the operating
voltage is applied. If this jumper is not attached, the pin START has to be tied to GND for a short
moment to run the user program. If you use the computer together with the Application-Board, this
jumper must not be attached because the Application-Board provides a START button, which is
connected to this pin.
Caution:
In all cases it is required to remove this jumper if a user program download to the computer
shall be executed.

Uref

JP1 at Unit M2.0
JP8 at Unit M1.2
This jumper connects the reference voltage for the AD-coverter to the 5V operating voltage. The
accuracy of the 5V voltage provided by a voltage regulator is fitting the requirements in common
applications. To achieve more accuracy a dedicated precise 5V reference voltage can be applied at
the Uref terminal. In this case the jumper has to be removed.
Caution:
Other voltages than 5V (+-10%) are not allowed to be connected to this terminal.
To operate the computer together with the Application-Board, this jumper has to be removed.

Connecting external circuits to ports

All usable signals and ports of the computer are connected to two rows of pins, that can be directly
plugged into your application. So the controller ports can be connected to the user application circuit.
There are three types of ports to distinguish
special digital ports
-
standard I/O Ports
-
analog ports
