F01NVINIT

Reinitialize non-volatile memory and perform a

software reset.

No status message will be generated. There

will be a short delay and then the Vortex

will reset.

8.101. NVLOCK -- Lock/Unlock Non-Volatile Memory

This command controls the non-volatile memory lock feature. When NVLOCK is enabled, the user may not save

any system settings to non-volatile memory. This includes global parameters, presets, macros, labels, and logic

assignments. The lock applies whether the user tries to make the changes via RS-232, front panel, logic inputs,

or any other method. The user will still be able to query all the features of the device, but will get an error

message if an attempt is made to change them. When NVLOCK is disabled, the user has full access to the system

settings.

Usage of this command is similar to other boolean commands (see

Section 6.1) except that when disabling this

feature, the password must be supplied for the command to work. If an incorrect password is supplied,

'ERROR#005' will be generated. The examples below illustrate the correct usage. The examples assume that the

password has been set to 'aspi' (the default). The NVLOCK password can be changed via the

NVPSWD

command.

This command is saved to global non-volatile memory and is not part of a preset. Its value is saved each time it

is changed. It will retain its value after power-down. Since this command writes to non-volatile memory, there

will be a delay before an acknowledgment is returned.

Example Description Status Message

F01NVLOCK1

Lock the non-volatile memory to

prevent users from changing the

settings.

F01NVLOCK1

F01NVLOCK0,yumyum

Attempt to unlock the non-volatile

memory by using an invalid password.

F01ERROR#005 -- since an invalid password

was given, an error message was generated. If

error messages have been disabled (via the

ERROR command), then no status message will

be generated.

F01NVLOCK0,aspi

Unlock the non-volatile memory by

using the correct password.

F01NVLOCK0

F01NVLOCK?

Query the locked status of the non-

volatile memory.

F01NVLOCKx , where x is 0 or 1 depending on

whether the non-volatile memory is unlocked or

locked, respectively.

8.102. NVPSWD -- Change Non-Volatile Memory Password

This command sets or queries the non-volatile memory password. This password is used in conjunction with the

NVLOCK command. The non-volatile memory must be unlocked ('NVLOCK0') in order to use this command to set

or query the non-volatile memory password. If the non-volatile memory is locked, then this command will result

in 'ERROR#004'. The examples below assume that the non-volatile memory is unlocked.

Example Description Status Message

F01NVPSWDlemur

Set non-volatile memory password to 'lemur'.

F01NVPSWDlemur

F01NVPSWD?

Query the current non-volatile memory password.

F01NVPSWDlemur
