7.4 Software Setup
7.4.1 Using KV Software [KV IncrediWare (DOS)]
Starting KV IncrediWare (DOS) from the KV-L2
A personal computer, when connected to the KV-L2 of the designated station no.,
can transfer programs to multiple KV-300 CPUs and monitor their operations. To
use this function, change the environmental string as follows before starting the KV
IncrediWare (DOS).
SET KV-LNK=Y
By substituting Y with 0 or 1 to F, your personal computer can communicate with
KV-300 CPUs through the designated KV-L2 without requiring selection of the KV-
L2 station no.
Example
Starting KV IncrediWare (DOS)
C>SET KV-LNK=Y ENTER
C>MNU ENTER
Example
Starting KV IncrediWare (DOS) by using KV-L2 designated as station no.1
C>SET KV-LNK=1
C>MNU
Note: When KV-LNK is set to "Y", the KV IncrediWare (DOS) confirms the station
no. to be accessed whenever communication* is attempted. This permits frequent
changing of the station no. However, if KV-LNK is set to "1", for example, you can
change the station no. only after quitting KV IncrediWare (DOS) and resetting KV-
LNK to the desired number.
* "PC-Port" in the menu refers to the serial port on the KV-300 CPU, which is used
only for communication between the CPU and a computer. Ignore the L2 function
when using this port.
Setting the KV-L2 (in KV mode)
Set the KV-L2 station no. as follows.
Connect the personal computer to the KV-L2 using an RS-232C cable. Set the KV-
L2 connected to the personal computer station no. F. Connect the KV-L2 of station
no. F to other KV-L2s using the multi-drop method with RS-422A cables. Specify
station nos. 0 to 9 of the other KV-L2s.
Note: Use the station no. designated by the station no. selection switch on the KV-
L2.
