4.3.1. Read / write bit parameter „a“ (61h)

To exploit maximum memory capacity, several parameters are put together and transferred as “data pack”
under the following parameter codes:

Data1: 1 0 X X 0 X 0 X

┬ ──┬── ─┬─ ─┬─

│ │ │ └─── positioning direction 0/1 (UP/DOWN)

│ │ └─────── counting direction 0/1 (UP/DOWN)

│ └──────────── arrows 0/1/2/3 (UP/DOWN/UNI/OFF)

└──────────────── 1


Data2: 1 0 0 X 0 X 0 X

┬ ┬ ─┬─ ─┬─ ─┬─

│ │ │ │ └─── round actual value 0/1 (OFF/ON)

│ │ │ └─────── turn display 0/1 (OFF/ON)

│ │ └─────────── offset 0/1 (OFF/ON)

│ └────────────── reserved

└──────────────── 1


Data3: 1 0 0 0 0 X X X

┬ ───┬─── ┬ ─┬─

│ │ │ └─── suppress target 0/1/2 (ON/OFF/EVER)

│ │ └────── resolution 0/1 (1/100;1/10)

│ └─────────── reserved

└──────────────── 1


Data4/5: 0 0 1 1 0 0 0 0

───┬───

└───── reserved


Important: Only the bits marked ‘X’ may be altered. The permanent parameters „1“ and „0“ must not be altered
since this might create a control token ( tokens < 20h) what is not permitted in ASCII protocol.
