Casio IT-2000W manual About time stamping of files, About key input during communication

￿Note:

When the cable comes off while the communication takes place:

If the connection cable is accidentally unplugged while communication between the IT-2000 and PC is taking place, a communication error results and communication is interrupted. In this case the communication software on the PC will display an error message and interrupt transmission/reception, however, some data may remain in the transmission buffer. If an attempt is made to restart communication in this condition, the XY utility may receive illegal packets, hampering normal communication. If this occurs, terminate the communication software on the

￿PC side then restart it to restore normal communication.

About time stamping of files:

This utility supports the function to exchange time stamp information between the transmitted file and received file. The time stamp information to be exchanged will be processed assuming that it is Greenwich standard time. In contrast, the time used by the IT-2000 is the local time, and the time stamp of IT-2000 files are accordingly controlled based on the local time.

The XY utility, for file transmission/reception by means of the YMODEM protocol, will convert a time stamp in Greenwich standard time to a time stamp in local time, or vice versa. This time conversion is achieved according to the environment variable, TZ. In communication between two IT-2000 terminals, if, for example, TZ of the transmission side is "JST+5", the time stamp of a file to be transmitted will have five hours added. In this case the reception side will create a file by subtracting five hours from the time stamp of the received file.If the environment variable TZ is not set, this time conversion is not performed.

The time stamp made at XMODEM communication uses the system time of the reception side.

About key input during communication

Do not press any key during communication, otherwise file transmission/reception may be

hampered.
