EMMI Subsystem (Agilent 8922M Only)
DATA <data entry>
DATA <data entry>
Description Writes the DATA to the EMMI port.
Syntax EMMI:DATA <data entry>
Options This EMMI DATA is in the form:
num-decimal-digits/num-data-chars/emmi-hex-data
(no spaces)
Where;
• num-decimal-digits: (range: 1 through 3) The number of characters following to be
interpreted as num-data-chars.
• num-data-chars: (range: 0 through 510) The number of data characters that will follow.
NOTE: This must be an even number since every two characters will represent one byte
of hex data.
• emmi-hex-data: Hex character data. Each pair of characters represents one byte of
EMMI hex data.
When the data write is complete, a status bit will be set that reflects what happened with
the EMMI data. See the Status Subsystem for EMMI.
RESet
Description EMMI RESet clears out transmit and receive (message) buffers and sends XON (ready to
receive) frame to the mobile station.
Syntax EMMI:RESet
Options Not applicable.
TIMEout:MS:XON
Description Sets/queries the EMMI TIMEout (time limit) allowed for the mobile to send XON. This
adjusts a timer that provides the time delay needed when the EMMI bus is attempting to
send a message before the MS or the Agilent 8922M are ready. If the XON timeout expires,
then the STATus:EMMI:EVENt? will return a 4 (XON timeout exceeded).
Default GPIB and display unit is seconds (S).
Syntax EMMI:TIMEout:MS:XON?
EMMI:TIMEout:MS:XON <real> | [:FNUM]
Options Refer to Appendix B.
