● Checking the destination ID number for command transmission
Command: TRCOM
Response: mm
[mm = 01 to 31 (ID number)
mm = 00: ID number is not specified.]
■ Description of the procedure
1. Send the “TRCOMmm” command. (The N-400 sends back “OK”.)
The N-400 displays the specified ID number.
2. You can then send a command to the specified BL series without adding its ID
number.
(For the commands sent to the BL series, see the BL series User’s Manual.)
Example
• To start reading: Send “LON [CR]”.
• To end reading: Send “LOFF [CR]”.
• To go to the SETUP mode: Send “SSET [CR]”.
3. When the N-400 fails to send a command to the BL series, the BL series sends
back the following response:
NC: The BL series with the specified ID number is disconnected.
SERR: Communication error
4. After the command transmission is completed, be sure to send “TROFF”.
Otherwise, the N-400 cannot receive any commands.
