Reference:
The functions of the DIP switches on the memory unit are indicated in the table
below.
• SW1
Switch
Automatic transmission (writing from the memory Automatic transmission (writing from the memory
SW1-1 SW1 1
unit to the PT)
Automatic transmission (writing from the PT to Automatic transmission (writing from the PT to
SW1-2 SW1 2
the memory unit)
Manual transmission (Direction of transmission Manual transmission (Direction of transmission
SW1-3 SW1 3
and bank used selected at the PT touch panel)
SW1-4 Data type to transfer
• SW2
Switch
SW2-1 SW2 1 Disable/enable writing to PT Disable/enable writing to PT
SW2 2 SW2-2 Disable/enable writing to the memory unit Disable/enable writing to the memory unit
SW2-3 SW2 3 Area (bank) selection of automatic transmission * Area (bank) selection of automatic transmission. *
SW2-4 SW2 4 System/Screen simultaneous transmission System/Screen simultaneous transmission
* The memory unit stores system program or screen data for one PT in each of
areas (bank 0, bank 1). (The total data storage is for two PTs.) SW2-3 sets which
of these two banks is used for automatic transmission.
S The DIP switch function of the memory unit is supplemented to NT31/NT31C
with the Vj suffix.
S In the following cases, a mode setting error occurs.
• More than one of the SW1-1 to SW1-3 switches are set to ON.
• None of the SW1-1 to SW1-3 switches are set to ON.
