1.5		INSTALLING THE HARDWARE

	Connect the receiver to an unused COM port on the controlling computer.


1.6		INSTALLING THE SOFTWARE

	It is recommended that the software be installed on a hard drive, 
	but the software can be operated from a floppy disk.  Floppy disk 
	operation will be very slow because of the disk access time.


1.6.1	HARD DRIVE INSTALLATION

	To install PCSW, simply select 'RUN' from the 'FILE' menu in 
	FILE MANAGER and type <drv:>setup, where <drv:> indicates the
	disk drive where the PCSW diskette resides. Follow the setup
	utility instructions to customize the installation if desired.

	If installation is successful a program group should be created
	in the windows program manager window. A WJ icon designates
	the PCSW software.  

	Select the WJ icon to start the application.  At the main menu, 
	select the OPTIONS button.  When the button opens up, select the 
	COM port which will control the receiver.  Keep in mind that the 
	receiver's COM port can not be the COM port assigned to the mouse.

	Exit the NOVA PCSW software and select the TERMINAL icon typically 
	found in the ACCESSORIES GROUP under the PROGRAM MANAGER.  From the 
	TERMINAL Menu, select SETTINGS.  From SETTINGS, select COMMUNICATIONS.
	In the COMMUNICATIONS Menu, from the Connector listing, select the 
	COM port used to control the receiver.  Then, set the Baud Rate to 
	9600, set the Data Bits to 8, set the Parity to None, set the Flow 
	Control to Xon/Xoff, and set the Stop Bits to 1.  Select the OK 
	Button to exit the menu.

	While still in TERMINAL, SETTINGS, select the TERMINAL PREFERENCES 
	Menu.  In the TERMINAL PREFERENCES Menu, set the Terminal Modes to 
	Line Wrap, Local Echo, and Sound; set Columns to 80; set 
	CR -> CR/LF to Inbound and Outbound; set Cursor to Block and Blink; 
	set Translations to None.  Place a check mark for Show Scroll Bars
	and for Use Function Arrow and Ctrl Keys for Windows.  All other 
	selections can be set to their defaults.  Select the OK button to 
	exit the menu.


1.7		TESTING THE RECEIVER

	While still in TERMINAL, turn on the receiver and allow the receiver 
	to execute it's startup routine.  Once the receiver startup has 
	finished, enter "FRQ?" and press <ENTER>.  If there is communication 
	between the controlling computer and the receiver, the receiver will 
	respond with the receiver's current tune frequency.  If the response 
	is incorrect, verify the COM port selection and configuration.


1.8		OPERATING THE RECEIVER

	Once the software has been loaded and the controlling computer and 
	software configured, the software is available to control the 
	receiver.  When the Icon is selected, the NOVA PCSW Menu appears 
	with the WJ871Y UI Menu located within the NOVA PCSW boundaries.  
	This is the main operating menu.  From the NOVA PCSW menu, selecting 
	Config will bring a single fold-down selection of RF Input.  Selecting 
	RF Input presents three options.  Preamp, which applies 10 dB of gain 
	to the input signal; Attenuate, which applies 15 dB of attenuation to 
	the input signal, and, Normal, which does not alter the input signal.


1.8.1	THE WJ871Y UI (MAIN) WINDOW

	The software can control any of the receiver functions.  From the 
	WJ871Y UI window, the operator can:

	1.	Control the source of receiver control commands.  In the 
		upper left corner of the WJ871Y UI box is a small icon.  
		This icon indicates where control of the receiver resides.  
		If the icon is a black ball, the receiver is under local.  
		Selecting the Black ball with a mouse's left button changes 
		the ball to red.  A red ball indicates remote control, control
		from the computer.  However, an operator at the receiver can 
		deselect remote control at the receiver.  Selecting the red 
		ball with the mouse changes the ball to a red lock.  A red 
		lock indicates that the receiver is under remote control but a
		local operator can not deselect the remote control.

	2.	Control the receiver's tune frequency using the Frequency box. 
		The up and down buttons to the right of the box change the 
		last or selected digit.  Any digit can be selected by 
		highlighting that digit or by placing the cursor to the 
		right of that digit.  As with all windows applications, 
		any highlighted entry can be replaced by a typed-in value.  
		The accepted values of the Frequency box are from 0.000000 
		thru 30.000000 MHz

	3.	Control the step size of the frequency increment/ decrement 
		using the Step control.  This option is selected by placing 
		a check in the box to the left of the word Step.  Once the 
		option has been selected, the Frequency box changes by the 
		value in the Step box whenever the frequency buttons are 
		pressed.  The up and down buttons located to the right of 
		the Step box change the last or selected digit in the Step 
		box.  Any digit can be selected by highlighting that digit 
		or by placing the cursor to the right of that digit.  The 
		accepted values of the Step box are .001 kHz and greater.

	4.	Monitor the strength of the tuned frequency, in dBm, in the 
		SigStr box.  The operator can not modify this value.

	5.	Control the type of gain control that the receiver uses with 
		the AGC box.  Pressing the single down arrow beside the large 
		box presents the menu of available gain types:  Manual, Slow, 
		Fast or Medium.  When a gain type is highlighted, the 
		selection is removed and the selected type appears in the 
		large box.  When Manual is selected, the Gain box is available 
		for operator selection using the up and down buttons to the 
		right of the Gain box or by highlighting the present value and 
		entering a new value.  The accepted values of the Gain box are
		0 thru 127 dB.  In all other gain modes, the Gain box is 
		"grayed" out and is not available.

	6.	Control the detection mode of the receiver using the Detection 
		Mode box.  Pressing the single down arrow beside the large 
		box presents the menu of available detection modes:  AM, FM, 
		CW, USB, LSB, ISB, and SAM.  When a detection mode is 
		highlighted, the selection is removed and the selected 
		type appears in the large box.  When CW is selected, the 
		BFO box becomes active.  The operator then selects the BFO 
		frequency using the up and down buttons to the right of the 
		BFO box or by highlighting the present value and entering a 
		new value.  The +/- key to the left of the BFO box identifies 
		whether the BFO value is added or subtracted.  When any other 
		detection mode is selected the BFO portion is "grayed" out.  
		The accepted values of the BFO box are +8000 thru -8000 Hz.

	7.	Control the IF bandwidth of the receiver using the IF BW box.  
		When the down arrow beside the IF BW box is selected, a menu 
		of 66 IF bandwidths is available.  When a bandwidth is 
		highlighted, that bandwidth is selected.  The accepted 
		values of IF bandwidth range from .056 kHz thru 16 kHz.

	8.	Control the use of squelch and the squelch value.  Placing 
		a check in the box to the left of Squelch allows squelch 
		to control receiver functions.  The box to the right 
		indicates the signal strength required to break squelch.  
		The value in the Squelch box is available for operator 
		selection using the up and down buttons to the right of 
		the Squelch box or by highlighting the present value and 
		entering a new value.  The accepted values of the Squelch 
		box are -135 thru 0 dBm.

	9.	Select the SCAN menu by "pressing" the Scan button with 
		the mouse.  When this occurs, the SCAN window is superimposed 
		over the WJ871Y UI window.


1.8.2	THE SCAN WINDOW

	From the SCAN menu, the operator can:

	1.	Select the receiver's scan parameters.  In the Scan Range 
		box, the operator changes the scan start frequency (From) 
		and scan stop frequency (To) by highlighting the current 
		value and entering a new value, in MHz.  The operator 
		changes the size of the scan step by using the up and down 
		arrow buttons to the right of the Step box or by highlighting 
		the current value and entering a new value, in kHz.  The 
		operator changes the time that the receiver will dwell on a 
		frequency that breaks squelch by using the up and down arrow 
		buttons to the right of the Dwell box or by highlighting the 
		current value and entering a new value, in seconds.  The 
		accepted values for the frequency start (From) and stop (To) 
		values are from 0.000000 MHz to 30.000000 MHz.  The accepted 
		values for the Step are 0.001 thru 25 kHz.  The accepted 
		values for the Dwell time are 0.500 thru 20 seconds or 
		INFIN (infinity).

	2.	Select lockout frequencies.  This capability is disabled
		in the current version.

	3.	Initiate a frequency scan by clicking the Start Scan button   
		Once the scan has begun, the Start Scan button changes to 
		Continue.  Should it be necessary to stop the scan, simply
		click on the Stop button.  Clicking the Start Scan button 
		will reset the scan to the From frequency before resuming the 
		scan, however clicking on the Restart button will resume 
		the scan from the current frequency. The operator can 
		suspend the scan by clicking the Pause button. The Scan 
		resumes when the Continue button is clicked.
