************
Users who program their own custom application software to
communicate with the TPS2000B/TPS2000 should read the following:

For optimal performance, when programming and communicating to the
instrument the following is recommended:

(1) Be familiar with the programmers guide Status and Events section.

(2) Configure the rear RS232 on instrument, including properties of Baud,
Flow control, EOL string and Parity. Press the UTILITY button.
Select i°Optionsi± option. And press the i°RS232 Setupi± option to configure the 
Properties. 


(3) Controlling programs should use the *STB query in preference to
the serial poll following a service request (SRQ).

Why:  A serial poll following a service request (SRQ) may cause
communication to hang.


(4) Programs should check for a timeout error after each read.

Why: In rare circumstances, the read following a query may time out.
When a timeout error is observed, it is necessary to re-send the
query and re-read the query response.
