Wiring the data interface CAN 1-IN/OUT
The CAN interface of the ICR890 System is used in the following configurations:
•
In the case of single-side reading, the peripheral equipment should be wired centrally
at the MSC800.
•
In the case of multi-side reading, the ICR890 System works with the MSC800 together
with further camera systems, bar code scanners and volume measurement systems
(camera control).
¾
Connect the ICD890 Camera to the 5-pole M12 socket and the open end via the CAN
1-IN connection using the cable no. 6021166. (See
for pin/wire
colour assignment.)
¾
Attach the open cable end to the CAN 1 connection in the MSC800.
¾
Attach the terminal resistance no. 6021167 to the CAN1-OUT connection of the
ICD890 Camera.
The signals for the reading pulse and increment are transmitted to the ICR890 System via
the CAN bus. Direct connection to the ICR890 System is, thus, not required. The HOST and
AUX data interfaces as well as the signals of both switching outputs (for single-side reading)
are accessible via the CAN bus at the MSC800. The ICR890 System and the MSC800 have
to be configured accordingly as Slave or Master for this purpose (see
).
