8. ANALOGUE INPUTS
Notes:- Options of four analogue inputs must be specified when ordering.
WindMaster Part 1590-PK-050 is supplied with four off 12 bit analogue inputs.
Use Gill Wind Software to enable Analogue inputs.
Information on how to change the formats and all the settings follows in Section 10, CONFIGURING.
Averaging (G command) does not apply to Analogue inputs. If the G command is set for example to
G10, one reading every 10 seconds, then the last value displayed will be output until the 10 second point
arrives and a new instantaneous (non averaged) reading will be output.
Analogue inputs are not supported in Syncpoll 1 mode.
