9.5 Command List

In depending from the specific commands, the following characters are used:

?... host (e.g. PC) requests for a parameter value of the unit

!... unit acknowledges a valid parameter request and responses with the parameter value

=... host forces the unit to set a certain parameter

#... unit informs the host, a parameter was set on the control panel manually

*... unit’s error response

Table 5: Command List

(1)P = Poll Mode (Request for a parameters), B = Burst Mode (continuous sending of parameters in the burst string), S = Set (Command for setting a parameters), N = Notification (Acknowledgment for setting a parameter)

(2)n = number, X = uppercase letter

(3)see section 9.3.2 Burst Mode, p. 40

(4)Setting peak hold cancels average, and vice‐versa. 300.0 means reset only with external trigger

(5)The sensor restarts after a baud rate change.
