9 Data Security

9.1 Introduction

Ensuring that your VFD2041 display’s exactly what you want it to can be the difference between a

projects success and failure. This is why we incorporate features such as Data Lock into the VFD2041 With

this new feature you now are in control over of how and when settings will be changed so there is no need

to worry about the module acting exactly like you expected it to because all the settings may be locked and

remembered for the next power up.

9.2 Set Remember

Syntax

Hexadecimal 0xFE 0x93 [switch]

Decimal 254 147 [switch]

Parameters

Parameter Length Description

switch 1 0: Do not remember, 1: Remember

Description This command allows you to switch the remember function on and off.

To use the remember function, set remember to on, then set all of the

settings that you wish to save, settings that are listed as ’Remember:

Yes’ support being saved into the non-volatile memory. After you have

set all of the commands that you wish to save, you may then cycle the

power and check the display settings to ensure that all the settings have

been saved. If you wish to use remember again after cycling the power,

you must set it to on again.

NOTES

• Writing to non-volatile memory is time consuming and slows down the operation of

the display.

• Non-volatile memory has a ‘write limit’ and may only be changed approximately

100,000 times.

Remembered No

Default Do not remember
