The parameter IDs that you use to send settings are the same as when you request settings. For example, to set
the chartspeed you would use a parameter ID '15'.
Querying Parameter settings
To query a setting use the following 6 character sequence: <CTRL+P><Request ID><space><Parameter ID>
The Request ID is a command that the Echotrac recognizes as the command for a parameter value request.The
Echotrac CV will then reply with “#CV3,P,”<UNITS><PING NUMBER><PARAMETER ID><VALUE>.
The Units is a single character F or M for Feet or Meters. The ping number is 8 characters, the Parameter ID is 2
characters and the value is 8 characters. Example:
<CTRL+P>86 00
#CV3,P,F000000010000000168
Note:
The Serial Parameter Request feature is supported in the following firmware versions only (See table
below). Also, as of version 3.06 the ID used to request a parameter value changed from 86 to 187.
