6.2 Setup Procedure
For setup and connection procedures, see p. 10. This section describes the proce-
dures for setting the N-400, BL series and PLC only.
6.2.1 Setting the BL series
1. Set “Multi-drop Link” to “Enable”. (Click the button.)
2. Enter the ID numbers (1 to 31) for the connected BL series. Be sure not to
assign the same ID number to different units.
3. Set the RS-485 communication parameters (baud rate, data length, parity and
stop bit length) for the BL series according to the N-400’s settings. The default
settings of the BL series and the N-400 are as follows:
Baud rate: 9600 bps
Data length: 7 bits
Parity: Even
Stop bit length: 1 bit
Note: To increase the response speed, set the BL series’ baud rate to 38400 bps.
4. Setting “Handshaking protocol” or “RTS/CTS” is not effective.
5. Set “Header” to “None”. Setting “Delimiter” is not effective.
* To use multi-head scan mode, set the following parameters.
Additional setups for multi-head scan mode use
1) To use the N-400 in multi-head scan mode, set the BL series’ reading mode to
“Single label”.
2) Set the trigger input signal type to “Level”.
3) Set the read error code according to the N-400’s setting.
Normally, the read error code is set to “ERROR” (default setting).
4) Set the reading start command and read end commands according to the N-
400’s settings. Normally, these commands are set to “LON” and ”LOFF” respec-
tively (default settings).
* Change other parameters as required.
