5.1.2 Setup procedure
For setup and connection procedures, see p. 10. This section describes the
procedures for setting the N-400, BL series and host computer only.
Setting the BL series
1. Set “Multi-drop Link” to “Enable”. (Click the button.)
2. Assign ID numbers (1 to 31) to 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 for 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 the terminator is not effective.
6. Set the BL series’ reading mode to “Single label”.
7. Set the trigger input signal type to “Level”.
8. Set the read error code of the BL series according to the N400’s setting.
Normally, the read error code is set to “ERROR” (default setting).
9. 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” respectively (default settings).
* Set other parameters as required.
