Using a Memory Unit Section 3-5
In systems where there are frequent setup changes, by preparing a number of
Memory Units in advance and recording screen data in them in accordance
with the control performed in each case, the NT31/NT31C screen data can be
changed simply by installing the Memory Unit, without connecting to the Sup-
port Tool.
In addition, even if NT31/NT31C is replaced, the previous status can be main-
tained simply by installing the Memory Unit that retains the system program
and screen data of the previous NT31/NT31C.
By using the following combinations, data can be stored (backed up) to a
Memory Unit.
• Screen data for two PTs.
• System program for two PTs.
• System program and screen data for one PT.
One Memory Unit can store the screen data for two PTs.
Note 1. Make sure that the power supply to the PT is OFF before connecting or dis-
connecting a Memory Unit.
After mounting a Memory Unit, be sure to tighten its two screws.
2. During data transmission, do not turn off the power supply to the NT31/
NT31C or reset it.
3. Do not touch the PCB (printed circuit board) with bare hands.
Reference: • When a Memory Unit is mounted, the NT31/NT31C cannot be set to the
operating status. On completion of data transmission with a Memory Unit,
always disconnect the Memory Unit from the NT31/NT31C before starting
NT31/NT31C operation.
• Memory Units (NT-MF261) can be used in common for the following PT
models: NT31, NT31C, NT631, and NT631C. One Memory Unit can store
screen data for up to two PTs of different models. However, 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 correct since these models have different numbers of colors.
• One Memory Unit can store a system program for up to two PTs of differ-
ent 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.
• 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 set-
tings 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.).
