3-5SectionUsing a Memory Unit (-Vj Versions)
40
Reference: S When a memory unit is mounted, the NT31/NT31C cannot be set to the oper-
ating status. On completion of data transmission with a memory unit, always
disconnect the memory unit from the NT31/NT31C before starting
NT31/NT31C operation.
S Memory units (NT-MF261) can be used in common for the following PT mod-
els: NT31, NT31C, NT631, and NT631C (with or without the Vj suffix). One
memory unit can store screen data for up to two PTs of different models. How-
ever, since the data compatibility is not complete between NT31/NT31C and
NT631/NT631C, an error may occur if an attempt is made to read NT631C data
with an NT31C. (The data must be converted using the Support Tool.)
Note also that although there is data compatibility between the NT31 and
NT31C, and between the NT631 and NT631C, the display may not be cor-
rect since these models have different numbers of colors.
S One memory unit can store a system program for up to two PTs of different
models. In order to transmit a system program from the memory unit to the
NT31/NT31C, the system program must be compatible to the target PT model.
S The statuses of memory switch settings and system settings can be recorded
to the memory unit besides screen data. When the data in the memory unit is
written into the NT31/NT31C, make sure that these settings can be adapted to
the NT31/NT31C used before transmission.
3-5-1 Installation Method
Install the memory unit (NT-MF261) at the expansion interface connector at the
rear of the NT31/NT31C as shown in the figure below (the expansion interface
connector is located underneath the note label.).
Mounting screws
3-5-2 Method of Use
As shown in the figure below, a memory unit has two sets of four DIP switches,
and the operation is determined by the DIP switches that are set at startup.

Factory setting is turned all to off.
Note 1. Always confirm that the power to the NT31/NT31C is off before setting the
DIP switches.
2. Do not touch the PCB (printed circuit board) directly with bare hands.
