Fluke RPM4 Calamb adder, mult CalDate, CALAMB=adder, mult CalDate, Adder, Mult, Baud, Parity

4. REMOTE OPERATION

CALAMB

Purpose	Read or set the on-board barometer calibration.
Command	“CALAMB adder, mult,			CalDate”
Query	“CALAMB?”
Classic	“CALAMB=adder, mult,			CalDate”
	“CALAMB”
Defaults	“CALAMB = 0.0, 1.0, 19800101”
Arguments	Adder:	The Barometer calibration adder (PA), in Pascal.
	Mult:	The Barometer calibration multiplier (PM) from 0.1 to 100.
	CalDate:	The date of the calibration in the format “YYYYMMDD”
Remarks	The barometer calibration information can be accessed with this program message. Using this
	program message overwrites the current calibration coefficients, so caution must be used.
	Changes made take effect immediately.
Example	Cmd sent:	“CALAMB? 2.1, 1.000021, 20011201”
(enhanced)	Query reply:	“	2.10, 1.000021, 20011201”
Example	Sent:	“CALAMB=2.1, 1.000021, 20011201”
(classic)	Reply:	“	2.10, 1.000021, 20011201”
Errors	ERR# 6:	One of the arguments is out of range.
See Also	3.5.7.1, 5.3
COM1
Purpose	Read or set the RS232 settings for				the COM1 port.
Command	“COM1 baud, parity, data, stop”
Query	“COM1?”
Classic	“COM1=baud, parity, data, stop”
	“COM1”
Arguments	Baud:	The baud rate. This may be ‘300’, ‘600’,’1200’,’2400’,’4800’, ‘9600’ or ‘19200’.
	Parity:	The data parity. This may be ‘O’ for odd, ‘E’ for even, or ‘N’ for none.
	Data:	The number of data bits. This may be ‘7’ or ‘8’.
	Stop:	The number of stop bits. This may be ‘1’ or ‘2’.
Defaults	“COM1 2400,E,7,1”
Remarks	The COM1 port is used to communicate to the RPM4. When the COM1 port configuration of the
	RPM4 is changed, the program message reply (COM1 use only) is sent at the old COM1 settings,
	but all subsequent communications are accomplished at the new COM1 settings.
	A 250ms or longer delay after receiving the reply to this command will ensure that the RPM4 has
	changed the COM port settings and is ready for communications at the new settings.
Example	Cmd sent:	“COM1 9600,N,8,1”
(enhanced)	Query reply:	“9600,N,8,1”			(No reply if GPIB-488)
Example	Cmd sent:	“COM1? 9600,N,8,1”
(enhanced)	Query reply:	“9600,N,8,1”
Example	Sent:	“COM1=9600,N,8,1”
(classic))	Reply:	“9600,N,8,1”
Errors	ERR# 7:	Missing or improper program message argument(s).

	3.5.2.1
COM2
Purpose	Read or set the RS232 settings for				the COM2 port.
Command	“COM2 baud,parity,data,stop”
Query	“COM2?”
Classic	“COM2= baud,parity,data,stop”
	“COM2”
Arguments	baud:	The baud rate. This may be ‘300’, ‘600’,’1200’,’2400’,’4800’, ‘9600’ or ‘19200’.
	parity:	The data parity. This may be ‘O’ for odd, ‘E’ for even, or ‘N’ for none.
	Data:	The number of data bits. This may be ‘7’ or ‘8’.
	stop:	The number of stop bits. This may be ‘1’ or ‘2’.
Defaults	“COM2 2400,E,7,1”
Remarks	COM2 is generally used to allow the host computer to communicate through the RPM4 to an
	additional device connected to COM2. This can be useful if the host computer does not have 2
	serial ports available.
Example	Cmd sent:	“COM2 9600,N,8,1”
(enhanced)	Query reply:	“9600,N,8,1”			(No reply if GPIB-488)
Example	Cmd sent:	“COM2? 9600,N,8,1”
(enhanced)	Query reply:	“9600,N,8,1”
Example	Sent:	“COM2=9600,N,8,1”
(classic)	Reply:	“9600,N,8,1”
Errors	ERR# 7:	Missing or improper program message argument(s).
