Setting the N-400
Using the N-400 setup software, set the N-400 as follows:
1. Set the host mode to multi-head mode (Click the button). ( ➮ See p. 38.)
2. In multi-head mode, connect the trigger input to the N-400 so that all BL series
connected to the N-400 are controlled as if they are a single bar code reader.
You must set the “Read mode” and “Trigger input signal type” of the N-400.
3. Enter the ID numbers of 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 host
computer’s settings on the “RS-232C SETUP” screen. ( ➮ See p. 42.)
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.)
6. Set the read error code of the N-400 according to the BL series’ setting. Nor-
mally, the read error code is set to “ERROR” (default setting).
7. 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).
Setting the host computer
Set the RS-232C communication parameters (baud rate, data length, parity and
stop bit length) for the host computer according to the N-400’s settings.
