6.2.2 Setting the N-400
Using the N-400 setup software, set the N-400 as follows:
For the difference in settings depending on the type of the link unit or PLC, see
“Setting the PLC” on the next page.
1. Set the host mode to multi-drop link mode or multi-head scan mode. ( ➮ See p.
38.)
2. Set the PLC link on the “PROTOCOL SETUP” screen. (See p. 40)
• PLC model name
To use the KV-L2 in “Link” mode, select “SYSMAC-C” for the N-400’s
setting.
• DM head address
• Trigger input through PLC
• Setting PLC unit number/station number
• Setting file register to “Enable” or “Disable”
3. Enter the ID numbers for the connected BL series on the “ID SETUP” screen.
( ➮ See p. 42.)
4. Set the baud rate, data length, parity and stop bit length according to the PLC’s
settings on the “RS-232C SETUP” screen. ( ➮ See p. 42.)
Setting "RTS/CTS" protocol is not effective when PLC link is enabled.
5. Set the baud rate, data length, parity and stop bit length according to the BL
Series’ settings on the “RS-485 SETUP” screen. ( ➮ See p. 43.)
Note: To increase the response speed, set the RS-485 communication baud rate
to 38400 bps. (Set the BL series’ baud rate to this value as well.)
* To use multi-head scan mode, set the following parameters.
Additional setups for multi-head scan mode use
1) In multi-head scan mode, connect the trigger input to the N-400 so that all of the
BL series connected to the N-400 are controlled like a single bar code reader.
You must also set the “Read mode” and “Trigger input signal type” on the N-
400.
2) Set the read error code according to the BL series’ setting. Normally, the read
error code is set to “ERROR” (default setting).
3) Set the reading start command and read end commands according to the BL
series’ settings. Normally, these commands are set to “LON” and ”LOFF”
respectively (default settings).
