How to Calculate Checksum Value

Format of NuDAM Commands

(LeadingCode)(Addr)(Command)(Data)

[Checksum]

<CR>

When checksum is enable then 

[Checksum] 

is needed, it is

2-character.

[Checksum]

 = 

(

(Leadi(Addr)+(C(Data)

) MOD 0x100

Example 1:  checksum is 

disable

User Command :  $012<CR>
Response          :  !01400600

Example 2:  checksum is 

enable

User Command :  $012

B7

<CR>

Response          :  !01400600

AC

‘$’ = 0x24

‘0’ = 0x30

‘1’ = 0x31

‘2’ = 0x30

B7 = ( 

0x24 + 0x30 + 0x31 + 0x32 

) MOD 0x100

 ‘!’ = 0x24

‘0’ = 0x30

‘1’ = 0x31

‘4’ = 0x34

‘6’ = 0x36

AC

 = 

( 

0x24 + 0x30 + 0x31 + 0x34 + 0x30 + 0x30 + 0x36 + 0x30
