CAN Troubleshooting
If you meet some problems when communicating with PC by CAN interface,
please check the following items:
•
PC and the instrument must have the same baud rate.
•
Ensure you have used the correct communication cable (CAN_H,
CAN_L). Please pay attention that some cable may not have a
correct internal wiring even it is with an appropriate plug.
•
The interface cable is correctly connected (CAN_H to CAN_H,
CAN_L to CAN_L).
•
If the communication signal is poor or unstable, it is recommended
to con- nect a 120 Ω terminating resistance.
–
The connection diagram of a single device is as below.
–
The connection diagram of multiple devices is as below.
When multiple devices are connected, it is recommended to
connect the pin 8 (GND) of the P-IO terminal on the rear panel
of these devi- ces in parallel, and the communication quality
will be improved in the entire CAN network.
9.4 GPIB Interface (Optional)
The GPIB (IEEE-488) interface is assembled in the IT-E176 communication
board. Use a GPIB cable to connect GPIB interfaces of the instrument and
PC. Please ensure that the screws have been screwed down in order to have
a full connection.
GPIB Configuration
Each device on the GPIB (IEEE-488) interface must have a unique whole
num- ber address between 1 and 30. Your computer’s GPIB interface card
address must not conflict with any instrument on the interface bus. This
setting is nonvo- latile; it will not be changed by *RST.
