•
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.
10.4 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.
When you purchase the interface accessory and successfully insert it into the
corresponding position on the rear panel of the instrument, the menu item for
changing the GPIB address appears in the System menu. The specific steps are as
follows:
1.
Ensure that the instrument's power switch is off, that is, the instrument is
