Matrix 120
It is recommended to connect the device CHASSIS to earth ground (Earth) by
setting the appropriate jumper in the CBX connection box. See the CBX
Installation Manual for details.
Main Serial Interface
The signals relative to the following serial interface types are available on the
CBX spring clamp terminal blocks.
The main serial interface type and its parameters (baud rate, data bits, etc.) can
be defined by the user via DL.CODE software. For more details refer to the Help
On Line page of the Reading Phase step (Channels) in DL.CODE.
Details regarding the connections and use of the interfaces are given in the next
paragraphs.
This interface can also be used for configuration through DL.CODE, see Step 4C
- Serial Device Discovery.
RS232 Interface
The RS232 interface is generally used for Point-to-Point connections. When it is
connected to the host computer it allows transmission of code data.
The following pins are used for RS232 interface connection:
It is always advisable to use shielded cables. The overall maximum cable length
must be less than 15 m (49.2 ft).
CAUTION
Do not connect to the Main Interface spring clamp terminals if using Host Interface Mod-
ules (Fieldbus) with the CBX500.
