7.1.5
Pin 8 PG1, pin 14 PG2, pin 15 PG3
Internal wiring
For simplifying the external wiring, three additional ground connections are available. They are connected with the
GND
supply ground via one PTC fuse each.
The following assignment is recommended:
pin 8
PG1
= analogue ground (for pin 21
AI1
, pin 22
AI2
, pin 23
AI3
)
pin 14
PG2
= reserve ground
pin 15
PG3
= RS232 ground (9 pole D-Sub: pin 5)

Pin 9 CNL, pin 10 CNH
INFORMATION
The termination of the CAN lines (optional positioning of the 120
Ω terminating resistor) may be
executed by BRUSA. This is to be indicated by the customer when making the order.
Internal wiring
CAN 2.0 B (baud rate can be parameterised, e.g. 125k, 250k, 500k, 1Mbit)
Both pins are isolated from the
GND
ground and the remaining control signals (avoiding disturbances caused
by stray voltage).
Via the CAN interface, messages can be transmitted in accordance with the CAN matrix provided by BRUSA
as .dbc-file.
The following parameters of the CAN messages can be modified via the PARAM software:
