Using a Memory Unit Section 3-5

•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 NT631/NT631C, the system program must be compatible to the tar- get 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 NT631/NT631C, make sure that these set- tings can be adapted to the NT631/NT631C used before transmission.

3-5-1 Installation Method

Install the Memory Unit (NT-MF261) at the expansion interface connector at the rear of the NT631/NT631C as shown in the figure below (the expansion interface connector is located underneath the note label.).
