7.2.3 Outline of Operation Modes
The KV-L2 has three operation modes. The desired mode can be set with the DIP
switch.
KV mode
In KV mode, the KV-L2 permits serial communications and transmission/reception of
text data through the KV-300 CPU modular jack.
Through a connected PC, the statuses of the KV-300 can be monitored, stored data
can be read or updated, and data can be fetched from an external unit.
The data to be fetched from the external unit must have STX and ETX as separa-
tors.
➮ Refer to "7.5.1 Operating in KV Mode" on page 1-253.
Display Interface mode
In display interface mode, the KV-L2 can control the KV-300 when used with
displays. Also, a connected personal computer can be used to monitor the KV-300
statuses and read or update stored data.
➮ Refer to "7.6.1 Operating in Display Interface Mode" on page 1-270.
Non-procedure mode
In non-procedure mode, the KV-L2 allows transmission/reception of text data. The
data does not require STX and ETX separators, but does require CR or CRLF
separators.
➮ Refer to "7.7.1 Operating in Non-procedure Mode" on page 1-292.
