Amplifier Queries
Advanced Query
Command Byte: ‘?’
Description:
The Advanced Query feature is intended to streamline the user’s polling loop
by allowing the user to construct custom query sequences. It is a complete
polling solution returning virtually any measurement you might want.
Measurements are requested using a variable length parameter list. The
length of the response will vary according to the measurements selected.
Measurements are returned in the order specified by the user.
The syntax of an Advanced Query command is as follows:
<start character><address><‘?’><parameter 1><parameter
2>...<paramater last><end character><check character>
Note: Separators (l) are shown to clarify the response. They are NOT part of
the response.
Example 1
Query: <STX>A?PQLV<ETX><checksum>
Example 2
Query: <STX>A?13A<ETX><checksum>
