7.4.3 Operation Check on IT-2000 (Using COM2KEY/XY)
If software coordination through simulation has been completed, it should be transferred onto the
IT-2000 for operation checks. To do this use the COM2KEY utility. The COM2KEY utility will,
when the COM port of a personal computer is connected with the IT-2000 via the dedicated cable
(DT-9689AX), use the personal computer as a dumb terminal of the IT-2000. For more information
about the COM2KEY utility refer to Chapter 8.9 "COM2KEY Utility".
A batch file (1.BAT) for initiating this COM2KEY utility is installed on the basic drive of the IT-
2000. It can be initiated by using the appropriate numeric key while the IT-2000 is in the command
prompt state. Since the major purpose of this utility is in assisting application development, it can be
directly called from AUTOEXEC.BAT. Moreover, it can be registered as a device driver.
This is convenient for developing device drivers to be registered in CONFIG.SYS. In this case,
register the COM2KEY utility before registering a developed device driver, and redirect the
COM2KEY utility to the personal computer with the start-up message of the device driver.
The following is the program transfer procedure used with the COM2KEY utility.
Connect the personal computer and IT-2000 with the dedicated cable (DT-9689AX).
Initiate the terminal software on the personal computer side and establish communication at
9600 bps. There are no particular requirements for use of the terminal software. YMOEM/bat
protocol is available.
Initiate COM2KEY on the IT-2000. For information about the initiation method, refer to Chapter
8.9 "COM2KEY Utility".
With the above procedure the command prompt of the IT-2000 will appear on the terminal
software screen. Under this condition initiate the XY utility and perform the program transfer, as
follows:
D: >
D: >xy/ry /N
After the above operation has been performed the IT-2000 remains in the wait state for file
reception with the YMOEM/bat protocol. Use the upload function of the terminal software to
transfer the application program.
If file transfer has been completed, the operation check of the program can be performed.
Of course, this application program can be initiated with a command line displayed by the
terminal software on the personal computer.
