Command Connector &

The & command connector can connect up to 6 basic commands to form a longer command so that it
will make the programming much easier.
For example, assume that the measurement of an instrument with IDN=4321 are going to be returned,
and (then) all the following 3 values--- (1) flow rate (2) velocity (3)POS totalizer---will be returned
simultaneously. The combined command would be W4321DQD&DV&DI+(CR), and the result would
be:
+1.12m3/d(CR)
+3.100m/s(CR)
+10m3(CR)

§6.4 Codes for the Keypad

The codes for the keypad should be used when the instrument is connected with other terminals that
operate the instrument by transmitting the ‘M’ command along with the keypad code. By this function,
remote operation of this instrument can be realized, even via the Internet.
