message format for VE.Direct protocol

hi,

I try to understand the communication of Bluestar MPPT 70/15 with external microcontroller system (e.g. arduino) with hex protocol
I received some exmaple codes from open source page of victron.
But there is a main point that i could not understand.

i could not undestand the main message format such that:

get MPPT Charger Volt ":7D5ED008C\n"

: is starting colon

7 is get command

D5ED is adress of charger voltage 0XEDD5

008C what is this phrase?

\n add of command


another example:

get MPPT charger current ":7D7ED008A\n"

: is starting colon

7 is get command

D7ED is adress of charger current 0XEDD7

008A what is this phrase?

\n add of command


i think everything will be clear for me if i can learn this part.

best regards,


VE.Direct
