Agilent Technologies E1301B SYSTem COMMunicate SERialn CONTrol DTR Example, Parameters Comments

SYSTem :COMMunicate :SERial[n] :CONTrol :DTR

Example

:COMMunicate :SERial[n] :CONTrol :DTR

Parameters

Comments

•Serial communication settings for the Agilent E1324A Datacomm interface can be stored in its on-board non-volatile EEROM only after the DIAG:COMM:SER[n]:STORe command is executed. These settings are used at power-up and DIAG:BOOT[:WARM].

•DIAG:BOOT:COLD will set the serial communication parameters to the following defaults:

–BAUD 9600

–BITS 8

–PARity NONE

–SBITs 1

–DTR ON

–RTS ON

–PACE XON

Setting baud rate for plug-in card 2.

SYST:COMM:SER2:BAUD 9600 (must be a card number 1 also)

SYSTem:COMMunicate:SERial[n]:CONTrol:DTR < dtr_cntrl> controls the behavior of the Data Terminal Ready output line. DTR can be set to a static state (ON OFF), can operate as a modem control line (STANDard), or can be used as a hardware handshake line (IBFull).

Parameter	Parameter	Range of	Default
Name	Type	Values	Units
dtr_cntrl	discrete	ON OFF STANDard IBFull	none

•The following table defines each value of dtr_cntrl:

Value	Definition
ON	DTR line is asserted
OFF	DTR Line is unasserted
STANdard	DTR will be asserted when the serial interface is
	ready to send output data. Data will be sent if the
	connected device asserts DSR and CTS.
IBFull	While the input buffer is not yet at the :STOP
	threshold, DTR is asserted. When the input buffer
	reaches the :STOP threshold, DTR will be
	unasserted.

•DIAG:BOOT:COLD will set … DTR to ON.

•*RST Condition: No change
