5.3 XTC/2 Protocols
One of these protocols is in effect if XTC/2 Ck Sum, XTC/2 No Ck Sum,
XTC/C Ck Sum or XTC/C No Ck Sum has been selected under the
RS-232 Protocol parameter. TCP/IP always uses the Standard protocol.
Unlike XTC/3’s standard protocol, which is binary based, XTC/2 protocols are
ASCII based. That is, numbers are represented by their ASCII codes, not as
"floats" or "ints".
5.3.1 Basic Command Structure
The following commands are available via the computer communications:
E. . . . . . . Echo. Returns the sent message.
H. . . . . . . Hello. Returns the model and software version number.
Q . . . . . . Query. Interrogates the programmable parameters and returns the value

U . . . . . . Update. Replaces the particular parameter with the value sent.
S. . . . . . . Status. Sends back pertinent information based on the specific

command, including the ACK, must be entered quickly. Otherwise, XTC/3
will fail to recognize the transmission as a valid command.
