5. When you enter a command in the “Send command” field, you can send
the command to the N-400 (or BL series). The format of the command to
be sent is “[Command] + [CR]”. Typing command and pressing [ENTER]
key sends the command.

commands previously sent are listed. (Up to 100 commands can be listed.)

Procedure for starting BL test mode using the “Monitor” screen
To start the BL series “Reading rate check” mode by sending a command
from the host computer to the N-400 in multidrop link mode, send the com-
mand using the “Monitor” screen according to the procedure below.
■ Using the N-400 in multi-drop link mode
1. Send the “Specific ID polling” command (see p. 72) so that polling is
performed only for the BL series to be tested. To send the command using
the Monitor screen, be sure to enter the command using uppercase
characters. [CR] of the following command corresponds to the [Enter] key
of the personal computer.
POLEmm[CR] * mm = 01 to 31 (ID number of BL series)
Note: When only a few BL series units are connected, you need not send this
command. However, when many BL series units are connected, the cycle of
the N-400’s polling for each BL series becomes longer than the reading cycle
of the test mode, causing the data to be stored in the N-400 buffer. To prevent
this, be sure to send the above command.
