2. Position the memory module over the metal plate on the carrier board. Orient the
memory module so that the catalog number label is visible when the module is plugged
into the connector on the CPU board.
3. Slide the memory module onto the connector on the CPU board, making sure it is firmly
seated on the connector and the metal retaining bracket is in place at the rear of the
module. IMPORTANT: READ THE “SWITCH POSITIONS” SECTION BELOW PRIOR
TO RESTORING POWER TO THE INSTRUMENT!
Failure to do so may result in overwriting the configuration database in the instrument or
the module.
2.3.2 Switch Positions
There are two switches on the memory module, which control the flow of data between the module and the
controller.
Read / Write Switch
This switch has two positions: READ/WRITE and READ ONLY.
Read / Write Position
With the switch in the READ/WRITE
position, data can be writing to the
memory module by the controller.
Use this position for backing
up the database in a controller,
or when the memory module is
left on the instrument during
operation and you want the
controller to update the
parameters in the memory
module’s database.
Read Only Position
With the switch in the READ ONLY
position, the database in the memory
module cannot be updated or
overwritten by the controller.
If a module is installed on a
controller with the switch in this
position, the controller generates a
diagnostic indicating the Memory
Module is write-protected.
Use this position on a
module being used to back up
and store a known good
database.
