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.
