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.
