NOTE
Leading zeros are deleted in ASCII. Therefore a space is always required between all
command parts and parameter parts.
As further alternative within CoLa A, depending on the preferences of the user, all
values can be written directly in Hex. This means however a 1:1 conversion of all letters
and characters including numbers and fixed hexadecimal values via the ASCII chart.
NOTE
The device will confirm parameter values always in hexadecimal code, regardless of the
code sent.

Start Data
This is again an example telegram for setting the user level "Authorized Client". As only
fixed hexadecimal parameter values are needed, the option to use parameter values in
decimal code with special indicator cannot be applied here:
•
Framing = <STX> = telegram start = 02 (Hex)
•
Data:
–
sMN = start of Sopas command (and blank) = 73 4D 4E 20 (Hex)
–
SetAccessMode = the actual command for setting the user level (and blank)
= 53 65 74 41 63 63 65 73 73 4D 6F 64 65 20 (Hex)
–
03 = fixed Hex value meaning user level "Authorized Client" (and blank) = 30
33 20 (Hex)
–
F4 72 47 44 = fixed Hex value, serving as password for the selected user
level "Authorized Client" = 46 34 37 32 34 37 34 34 (Hex)
•
Framing = <ETX> = telegram stop = 03 (Hex)
