3.4 Sending/Receiving Settings
Sending updated settings to the N-400
To send updated settings to the N-400, perform the following procedure.
1. Press and hold the N-400 test switch for five seconds. When the N-400 displays
“S0 ( 50 )”, the communication parameters are temporarily set as follows:
• Baud rate: 9600 bits/s
• Step bit length: 1 bit
• Data length: 7 bits
• PLC link: Disabled
• Parity: Even
If you know the current communication parameter settings of the N-400, this step is
not necessary. You can send data to the N-400 by setting the communication
parameters of the host computer using [COM PORT] so that they conform to the
current settings of the N-400. However, if PLC link is enabled, you cannot send
data to the N-400 without performing this step because the handshaking protocol is
set for PLC link only.
2. Click on [COM PORT] to set the communication parameters of the host com-
puter according to the values listed in the step 1. (above procedure). Select an
RS-232C port, and click on [OK].
3. Click on [Send setting (Save in N-400 EEP-ROM]. The updated settings are
then sent to the N-400.
