Printout mode display, also used to determine the
printout contents. Choices include turning
logged data and statistics on or off and
whether or not to print event summaries.

4. COMMUNICATIONS
DEFINITIONS
PARALLEL MODE
: Data is passed along multiple wires simultaneously. This is used for sending information to parallel
printers.
SERIAL MODE
: All of the data is passed along a single wire in a sequential stream. This mode is used when sending
information to a computer or serial printers. RS-232 is a type of serial mode communication.
BAUD RATE
: Baud rate is the speed at which serial communications take place, measured in bits per second. The baud rate
options for the Q-300 are 300, 600, 1200, 2400, 4800, 9600, and 19,200. The higher the baud rate, the faster the
communication. When trying to pass information from an instrument to a computer or serial printer, both must be set for
the same baud rate. (Baud rate settings have no affect on parallel printing.)
COM PORT
: Abbreviated name for a serial communications port on a computer (also called RS232 port). Most PCs have
between 1 and 4 serial ports referred to as COM1, COM2, etc... This is where the cable from the meter connects to the
PC. The COM ports generally will take the form of either a 25 pin male (has pins instead of holes) connector or a 9 pin
male connector.
4.1 Printing Data
The Q-300 may be connected to either a parallel or serial (RS-232) printer by using the proper cable and adapter. Data
may also be printed directly to a PC by using a communications package such as Procomm or Windows Terminal. The printout
contains the Overall Summary information and individual Events, if desired, including:
1.
All measurement parameters (Range, Weighting, etc.)
2.
Data Summary of all measured parameters (LEQ, LMAX, etc.)
3.
Start, Stop and Run Times and OL
The information printed will be that selected in the Print portion of the Setup Menu (PRNX - Refer to section 3). See the
end of this section for a sample printout. The printout sections selected in the setup menu are labeled on the sample printout for
clarity.
To connect the Q-300 to a parallel printer, the 056-957 Parallel Interface is required. The 10 pin circular connector
plugs into the jack on the top of the meter. The 36 pin flat cable connector plugs into the printer. The meter must be set for
parallel operation (PRLL option for Baud Rate, located in the Setup Menu - Refer to section 3).
The Q-300 and the printer should all have their power switches turned ON. The meter must be in PAUSE mode. The
display must be set to the PRNX portion of the setup menu. Pressing the RUN/PAUSE key will start the printout.
To interrupt a printout, press RUN/PAUSE again. Disconnect the interface from the printer before turning the Q-300 off.
The Q-300 can be connected to a serial (RS-232) printer or a PC by using the Serial Communications Interface (056-
956). A 25-pin male to male gender changer will be required for connection to the printer. The printer's communications
parameters must match that of the Q-300. Refer to the following section.
Some printers can work either in serial or parallel mode. The printer must be set up for one or the other. Simply
plugging into the correct connector is not sufficient. Refer to the printer's manual. THE Q-300 HAS A SEPARATE CABLE FOR
CONNECTING TO A PARALLEL PRINTER. THE SERIAL CABLE
CANNOT
BE ADAPTED TO WORK WITH A PARALLEL
PRINTER.
