Chapter 3 N-400 Setup Procedure

3

Reading the current settings of the N-400

To read the current settings of the N-400, perform the following procedure. (This
procedure is almost the same as the procedure for sending settings.)

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

Data length: 7 bits

Parity: Even

Step bit length: 1 bit

PLC link: Disabled

If you know the current communication parameter settings of the N-400, step 1. 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 step 1., 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 step 1. Select an RS-232C port and click
on [OK].

3. Click on [Send setting (Save in N-400 EEP-ROM)].

When you click on [Read N-400 settings], the settings of the N-400 can be read
on the host computer.
