Description:
ATYPE
parameter for CAN Daughter Board = 8
The CAN daughter board is particularly aimed at providing dedicated CAN chan-
nels for controlling servo amplifiers. It features opto-isolation and the ability to
support communications at 1M Baud.
CAN Connections
The CAN connection of the CAN daughter board is via a 9 way Male 'D' type con-
nector. Pinout is compatible with that suggested by the CAN in AUTOMATION
organisation:
No terminating resistor is fitted internally to the CAN daughter board. A 120 ohm
resistor must be fitted between pins 2 and 7 if at the end of the CAN network.
The daughter board CAN channel can be controlled using the Trio BASIC CAN com-
mand. Trio are also building into the system software dedicated communication
software to support particular communication protocols, such as that for
INFRANOR SMT-BD CANbus drives and some CANopen drives.
