12.18 Tilt Angle Pulse Ratio Request
Pedestal Control Command Type 1
Function To return the coefficient to convert parameter value using Tilt angle (position)
and Tilt speed commands to angle unit.
Command 005Bh
Length 1 byte Parameter
Value 1h
Length 4
byte Status
Value 11250 (2BF2h)
Reference •To return integral value multiplied 100000 to the conversion coefficient of
true Tilt angle. In case of angle conversion, divide it by 100000.
Example below,
Status value /100000 = 11250 /100000 = 0.1125
Note: The parameter of 12.2 Tilt Speed Assignment command can be
converted as under.
Tilt speed = 622 PPS = 622 × 0.1125 ≠ 70 degrees/s

Error Flag indicates in 2 figures hexadecimal and returns ASCII code value.
Example: e0 e1
In case of Parameter Error :
01010000B ⇒ 50h ⇒ 35h 30h
In case of Mode Error : 10010000B ⇒ 90h ⇒ 39h 30h
Condition of Error flag to be set
Parameter Error •Assign illegal parameters.
Mode Error
•Not in status of Camera ON.
•Not in status of Host Control Mode.
