4.2. USB Communication (EDD MEGATERM)
Function of EDD MEGATERM
Use the application software "EDD MEGATERM" compatible with the Windows 7/10-based PC for USB
communication.
Setting parameters, programming and various monitoring by USB communication can be done easily by
connecting CN0 of PC and the Driver Unit Model EDD with a USB cable. (No setting such as baud rate is
required.)
Caution : USB communication is dedicated for maintenance using the
MEGATERM. Do not use it for normal operation.
Caution : The connection cable with PC should be a double shielded item of 3 m or
less, and use USB mini-B for the connector on the Driver Unit side.
Caution : Depending on the usage environment, communication may be
interrupted. In that case, mount the high frequency division type ferrite
core with three turns on the Driver Unit side and PC side. (Refer to
Appendix 7)
Caution : When USB communication and RS-232C communication are performed
at the same time, USB communication is processed first, then RS-232C
communication is processed.
Caution : All functions cannot be used even if USB communication is performed
with USB communication software other than the EDD MEGATERM.
Table 4-1: Specifications of USB communication
The terminal screen of the EDD MEGATERM can be handled in the same way as the Handy Terminal,
but some operation methods and displays are different. The difference between RS-232C communication
and USB communication is described in this section.
Use of the oscilloscope function and FFT function enables more visual tuning. When high-speed sampling
is required, use an analog monitor.
The FFT can measure sampling acquisitions up to 500 [Hz] at 1 [ms]. If further measurement is required,
measure it with the oscilloscope connected to the analog monitor. For measurement method, refer to
"5.5.2. Setting Notch Filter."
