Remote Sets the GPIB remote enable line (REN) true which places an instrument in the
remote state.
Comments • The REMOTE 709ss (ss = secondary address) command places the
instrument in the remote state. The REMOTE 7 command, does not, by
itself, place the instrument in the remote state. After sending the
REMOTE 7 command, the instrument will only go into the remote state
when it receives its listen address.
• In most cases, you will only need the REMOTE command after using the
LOCAL command. REMOTE is independent of any other GPIB activity
and toggles a single bus line called REN. Most controllers set the REN
line true when power is applied or when reset.
Examples REMOTE 7 Sets GPIB REN line true
REMOTE 70900 Sets REN line true and

Serial Poll (SPOLL) The SPOLL command, like the *STB? Common Command, returns the
weighted sum of all set bits in an instrument’s Status Register (status byte).
Refer to "The Status Register" earlier in this chapter for a table showing the
contents of the Status Register.
Comments • The SPOLL command differs from the *STB? command in that SPOLL
clears bit 6 (RQS). Executing *STB? does not clear bit 6.
Examples 10 P= SPOLL (70900) Sends Serial Poll, places
response into P
20 DISP P Displays response
