4.3 Parameter commands and their significance
4.3.1 Read / write bit parameters „a“ (61h)
To exploit the maximum storage capacity, several parameters are put together and transferred as “pack”.
Parameter codes as follows:
Data1: 1 0 X X 0 0 0 0
┬ ──┬── ───┬───
│ │ └───── reserved
│ └──────────── arrows 0/1/2/3 (UP/DOWN/UNI/OFF)
└──────────────── 1
Data2: 1 0 0 X 0 X 0 0
┬ ┬ ─┬─ ─┬─ ─┬─
│ │ │ │ └─── reserved
│ │ │ └─────── turn display 0/1 (OFF/ON)
│ │ └─────────── offset 0/1 (OFF/ON)
│ └────────────── reserved
└──────────────── 1
Data3: 1 0 X X X 0 X X
┬ ┬ ──┬── ┬ ─┬─
│ │ │ │ └─── hide target 0/1/2 (ON/OFF/EVER)
│ │ │ └────── resolution 0/1 (1/100 or 1/10)
│ │ └────────── decimal point 0/1/2/3/4/5 (AUTO/OFF/0.0/0.00
│ │ 0.000/0.0000)
│ └────────────── reserved
└──────────────── 1
Data4/5: 0 0 1 1 X X X X
───┬───
└───── reserved
Important: Only bits marked ‘X’ may be altered. The fix values „1“ and „0“ must not be altered since thereby a
control token (tokens < 20h) might be created what is not allowed in ASCII protocol.

Parameter significance
Arrows
This parameter is for displaying arrows intended as support for the editing engineer. They indicate the direction for
the new setting (clockwise or counter clockwise, up or down). The following settings are possible
00 = Up If current value < target: arrow at the right; current value > target: arrow at the left
01 = Down Similar to „Up“, but direction of the arrows the other way round
10 = Uni If current value ≠ target: always indicate both arrows
11 = Off Arrows always hidden
