5) DIP Switch
a) The DIP switch is composed of 4 pins. The pins are num-
bered from 1 to 4 as shown in the diagram at the right.
b) Each pin is turned ON when pressed to the left.
c) Each pin is effective (read) at the following timings:
(1) When the reset switch is pressed.
(2) When power is turned ON to the Power Supply Module of the Rack to which the
Uniwire (H) I/F is mounted.
d) Each pin’s function is shown in the table below.

Uniwire (H) I/F according
to the table on the right.
OFF ON Sets Module to 200-m mode.
Transmission distance: 200 m max.
The baud rate depends on the
combination of the transmission distance
mode and the interface mode.
Baud rate: H-System 29.4 kbps
Normal System 28.5 kbps
ON OFF Sets Module to 500-m mode.
Transmission distance: 500 m max.
The baud rate depends on the
combination of the transmission distance
mode and the interface mode.
Baud rate: H-System 14.7 kbps
Normal Sywtem 14.3 kbps
Note (1) Never set both pins 1 and 2 simultaneously to ON or simultaneously to OFF. If you set
both pins either to ON or OFF by mistake, it will cause a pin setting error.
(2) Always leave pins 3 and 4 set to OFF. Setting these pins to ON by mistake may result in
incorrect outputs.
