7.7 Non-procedure Mode Programming
7.7.1 Operating in Non-procedure Mode
Communications protocol
In non-procedure mode, the KV-L2 can be connected to an external device having
an RS-232C or RS-422A terminal to write a series of text data (100 bytes maximum)
into data memory as a batch and to send text data from data memory to a connected
device.
Setting of the communications protocol and connection of the KV-L2 to an external
device are described below.
Setting the operation mode
Set the operation mode using the operation mode setting switch SET A (A1 to A4).
Use A1 and A2 to set the mode for port 1, and A3 and A4 to set the mode for port 2.
Turn OFF the power switch before setting the operation mode.
Set the operation mode setting switch A1 to A4 as above.
Setting the communications protocols
Set the baud rate, data bit length, parity, and stop bit with communications protocol
setting switch SET B (B1 to B8) according to the specifications of the external device
to be connected. Turn OFF the power switch before setting the switches.
