Remote Operation
4.1.6.2 Program Operation
Once the program is running, try the following commands and observe the
response of the instrument. Input from the user is shown in bold and
terminators are added by the program. The word [term] indicates the
required terminators included with the response.
ENTER COMMAND? *IDN? Identification query. Instrument will return a
string identifying itself.
RESPONSE: LSCI,MODEL211,21A0000,022607[term]
ENTER COMMAND? KRDG? Kelvin reading query. Instrument will return
a string with the present kelvin reading.
RESPONSE: +12.345[term]
ENTER COMMAND? INTYPE 0 Input type command. Instrument will change
the input type to silicon diode. No response
will be sent.
ENTER COMMAND? INTYPE? Input type query. Instrument will return a
string with the present input type setting.
RESPONSE: 0[term]
ENTER COMMAND? INTYPE 0;INTYPE? Input type command followed by input type
query. Instrument will change the input type
to silicon diode then return a string with the
present input type setting.
RESPONSE: 0[term]
The following are additional notes on using the Serial Interface program.
• If you enter a correctly spelled query without a ―?,‖ nothing will be
returned. Incorrectly spelled commands and queries are ignored.
Commands and queries and should have a space separating the
command and associated parameters.
• Leading zeros and zeros following a decimal point are not needed in a
command string, but they will be sent in response to a query. A leading
―+‖ is not required but a leading ―–‖ is required.
4.1.7 Trouble Shooting
New Installation
1. Make sure transmit (TD) signal line from the instrument is routed to
receive (RD) on the computer and vice versa. (Use a null modem
adapter if not).
2. Always send terminators
3. Send entire message string at one time including terminators.
(Many terminal emulation programs do not.)
