3 DESCRIPTION

The software described in this manual allows interactive operation with GL-T8500 and GL-T8600 transm itters. Here is a brief list of th e transmit ter features that the sof tware operates.

3.1 Status Display

The VDT displa ys principal transmi tter status continuou sly or spec ific transmitter status selectively. Principal status is show in three information blocks at the top of most screens:

• The stat us block prov ides present information on 20 crit ical paramet ers of the t rans-

mitter, in addition to the fault or alarm condition.

• The currents block p rovides amperage measurements for the dc power input of each

amplifier stage in the power amplifier.

• The powers bl ock prov id es w attage me asure men ts for fo rward and ref lecte d RF pow er

of most amplifier stages in the power amplifier.

3.2 Remote Control

The VDT can displ ay more specif ic transmitter st atus if desire d. Specific status i ncludes regulated voltage readings, programmed channel frequencies, and four full-screen information displ ays:

• The present faul ts display lists every tra nsmitter fault or ala rm available at the pre sent

moment.

• The stored faults display lists the transmitter fault or alarm that was stored when the

transm itte r firs t left norma l operati ng sta tus.

• The readings at fault display lists the status, currents, and power blocks that were stored

when the transmitter first left normal operating status.

• The presets display lists programmed transmitter parameters for all eight channels.

When the transmitter is in service and is responding to controller commands, the VDT can perform remote control functions:

• Adjust the transmitter’s RF power out to any wattage within the transmitter’s rated

forward power.

• Adjust the trans mitter’s low po wer a larm to an R F powe r out wat tage belo w which the

transmitter provid es an alert.

• Program frequencies into channels, if authorized with the frequency password.

Frequency password can be changed.

• Change entry passwo rd, used to gain access to VDT. Enable and disable use of entry

passw ord.

Note

C2000/I20 overwri tes user chang es when in remote mode.

3.3 Local Control

After the VDT has removed the transmitter from service, the VDT can still perform remote contro l fun ct ion s, but no w ca n perf o rm local contro l fun ctio n s:

• Key or unkey transmitter.

• Change betwee n analog, 2-le vel, and 4-level digital mod es.

• Change between eight channels.

• Calibrate total forw ard power (TFP) and total reflected power (TRP) using the appro-

priate external instruments.

4 INSTALLATION AND SETUP

This section requires user manuals for VDT hardware and emulating software. Before startin g this sec tion, ve rify that all hardw are requ ired to ru n the em ulating program has bee n inst alled into the V D T.

4.1 VDT Connection

Connect the VDT to the exciter/PA control equipment using the proper interconnecting cable. The exciter female DE-9 connector is configured as a serial, DCE, EIA-232 port. T he VDT (or computer) female DB-25 or male DE-9 input is con figured as a serial, DTE, EIA232 port. The typical serial input connector for the VDT is a female DB-25, and that of most computers is a male DE-9, but there is no gua ran tee of this.

4.1.1 VDT-to-Exciter Interconnect Cable

The DSP Exciter to VDT cable can be a straight through DE-9 to DE-9 cable, or a DE-9 to DB-25, EIA-232 adaptor cable, as shown in Figure 4-1 . These cable s m ay be purc hase d from a computer shop, adap ted usin g standard EIA-232 parts, or fabricated. The exciter end of the cable is always a ma le DE-9 connector. The VDT end can be a male or female DE9 or DB-25 connector, check your VDT for the correct connector type.

A 3-conductor cable can be used to fabricate either of the above mentioned cables, as only the TXD, RXD, and ground connections are needed. Connect the three conductors as show n in Figure 4-1.

Figure 4-1 DSP Exciter to VDT Cable

Gold Line VDT Glenayre Document Number : 9110.00164 INSTALLATION AND SETUP Issue 1, Rev. F: 09/03/96

4.1.2 Connecting the VDT to the Transmitter

Connect the VDT to the transm itter using th e proper cable(s). Plug the male DB-9 D CE connector into the jack marked VT-100 INTERFACE located on the front panel of the exciter/PA control. Plug the other end of the cable or the adapter into one of the VDT's serial ports. Note the desi gna tio n of this port for VDT start -u p.

4.2 Starting Up the VDT

Apply power to the VDT . If it has not yet been installed, install the emulating program and all so f tw are req uire d to ru n it .

4.2.1 Presetting the Emulating Program

Select the com m po rt I/O l ine setting s s creen o n the VDT. Change the cu rrent sett ings to those shown in Table 4-1. After you are done, save and exit the line settings screen.

Table 4-1 VT-100 Line Settings

parameter setting

baud rate 9600 parity none data bits 8 stops bits 1 port select desired port A common abbreviation for the above settings is: 9600 8N1.

4.2.2 Access VDT Communications

At this point, the VDT should display a screen containing the ENTRY LEVEL PASSWORD menu. From this menu, perform the following steps:

1. Type ABCD from VDT keyboard . As each letter is typed, an asteri sk (*) appears on

the screen under the phrase ENTER PRESENT PASSWOR D.

4.2.3 Changing Passwords

When the VDT is connected to the transmitter the first time, a password must be entered in order to access VT-100 communic ations. Enter the default p assword "abcd" to access VT100 communications. The VDT uses another password to access channel carrier frequency assignme nts. This passw ord is also initia lly the defau l t passw ord "abcd " . It is import ant to change these default passwords to secret passwords immediately after the VDT is connected the first time . By using two pass words, the fre quency passwo rd may be ma intained at a higher l evel of secrecy than the entry password. Th e entry password ma y be disabled if desired to permit immediate access to VT-100 communications. However, even if it is disabled, it is important to change the entry password to prevent unauthorized personnel from changing the default passw ord.

4.3 Using the VT-100-Emulating Program

Most VT-100-emulating programs have additional features, some of which can be helpful when operat ing the program as a transmi tter interface. The p rogram may be capable of saving the active, or present settings for the RS-232 link with the transmitter. Some program s have a log function, which saves the key strokes and displ ays f rom the current session. Th is feature is particu larly useful for savi ng the transmitte r parameters entered during a setup procedure. When used with a printer, the program may be able to dump the contents of the present screen display to the printer.

Caution

Some transmitter controllers may issue an alarm if a transmit command is sent with no resultant indication of transmitter forward power. This can be avoided by first placing the transmitter controller in a mode that does not allow it to issue alarms.

5 OPERA TION

5.1 VT-100 Screen Displays

Most VT-100 screens have four display areas as shown below. Display area 1 contains STATUS information, such as transmitter parameters and conditions. Display area 2 contains the value of CURRENTS through selected active devices within the power amplifier. Display area 3 contains the value of forward or reflected POWERS for s e lected act iv e devices within the power amplifier. Display area 4 contains the menu, which permits data input and selection of other menus. The VT-100 screens that do not have these four display areas are certain full-screen status displays. This section shows all four STATUS, CURRENTS, POWERS, and menu display areas, in addition to the full-screen status displays.

5.1.1 Display Area 1: STATUS

STATUS display area 1 contains two grou ps of two col um ns. The t ransmi t ter para me ter is in the left column of each group, and its value or condition is in the right column of each group. The entire display area is repeated and continuously updated on all VT-100 screens except certa in full-sc reen status displays. The STATUS displ ay a rea is displa y-only and does not permi t selec tions or dat a entry. The fol lowi ng text desc ribes each p aram eter and condition displayed in the STATUS display area.

FWD PWR (Forward Power)

This displa y lists the transm itter's a ctual forward RF ou tput pow er in watts . Sometime s described as total forward power, the value for this display is measured at the output of the PA's combiner board.

REF PWR (Reflected Pow er)

This displa y lists the transmitter's actual reflected RF power in watts. Sometimes described as total reflected power, the value for this display is measured at the isolator module on the rear of the PA.

EXC 26V (Excite r 26 Volts)

This display lists the exciter's actual 26-volt operating voltage. This voltage is measured at the power input of the exciter/PA control, and is normally supplied by the transmitter's 26volt power supply.

AGC (Automatic Gain Control)

This displa y lists the AGC voltage, a dc volt age that c ontrols the gain of the po wer amplifier . This voltage, generated by the PA metering board , is measured at the prea mplifier (first stage) on the PA's driver board.

Page 22

Gold Line VDT Glenayre Document Number : 9110.00164 OPERATION Issue 1, Rev. F: 09/03/96

Note

Do not confuse AGC voltage generated in the PA with AGC reference

volt age gene rated i n the excit er/PA co ntrol. T he PA's AGC voltage is produced by comparing AGC reference voltage against transmitter forward power.

V001 (Voltage-Controlled Oscillator 1)

This display lists the dc control voltage for VCO-1, in the exciter/PA control IF stage circuitry. The VCO1 con tro l vo lta ge , nec essary for phase-locking the VC O - 1 carrier to the 10-MHz reference signal, is generated by synthesizer-1.

display lists 0 Hz

• When in an alog mode and an input signal is prese nt above the p rogramme d limiting

value, causing the transmitter to impose deviation limiting, the DEVIATION display lists LIMIT.

• When in analog mode and an input signal is present above 100 Hz and below the

programmed limiting value, the DEVIATION display l ists the actual d eviation v alue. This value is the number of Hz between f between f

OFFSET

This display lists t h e progra mmed offset value fo r the mode c urre ntl y selec te d, a nd, w hen in the digital FSK mode, for the channel currently selected. This offset of the channel frequency is needed in order to reduce overlap area nulls when simulcasting. Offset value is the number of Hz added to or subtracted from the channel frequency to create the center frequency (digital FSK mode) or carrier frequency (analog mode), also known as f

and the highest FSK frequency, and between f0 and the lowest FSK

and the highest modulated frequency , and

and the lowest modulated frequency. See OFFSET for a description of f0.

MODE

This display lists the presentl y selected operating mode and, when in analog mode, also lists the audio response.

• If 2-LEVEL is listed, two-level FSK mode is sel ec te d .

• If 4-LEVEL is listed, four-lev e l FSK mo de is selec te d .

• If ANLG-FLAT is listed, analog mode and audi o response for flat is selected.

CONTROL

This display lists the transmitter's presently selected control state. This state is listed either as LOCAL or REMOTE.

• REMOTE - this i s th e t ran smitter's n o rm a l o pe rat in g mo d e. E x te rn al c o nt ro l i nputs such

as channel, m ode, and key comman ds are supplied by a devi ce such as a transmitte r controller and are obeye d by the transmitter. These commands are not possible through the VT-100 interface when in the remote control mode.

• LOCAL - this is the transmitte r's maintenance m ode. External control input s such as

chann el , m o de , an d k ey c o mmands are i gn o red by the transmitt er. These co m ma n d s, i n addition to maintenance, setup, and self test functions, are possible through the VT-100 interface when in the local control mode.

KEY STATE

This di spla y l ist s the tran smitter's p resently se lect ed ke y i n put state. Th i s st at e i s l isted as KEYED or UNKEYED. The logi c for this conditi on is det ec te d in the exc it er/PA control. A keyed condition indicates an external key hardline activation (in the remote control mode) or a VT-100 VDT [K] key software selection (in the local control mode).

FILTER

This display lists the rise time, in microseconds, of the presentl y selected digital premodulation filter. This rise time is effective for the digital FSK modes only, although it is always displaye d regardless of mode .

CHAN BW (Channel Bandwidth)

This display lists maximum bandwidth, in kHz, of all the transmitter channels. The bandwidth is determined by the filtering circuitry installed in the exciter/PA control.

5.1.4 Display Area 4:Menu

The remainde r of this section des cribes the menu display area 4. Unlike the other three display areas, most menus permit data input and parameter selection. Each menu is described i n five parts: ac cess procedure , sample menu , menu funct ion, menu opera tion, and active alpha function key list.

Page 27

Glenayre Document Number: 9110.00164 Gold Line VDT Issue 1, Rev. F: 09/03/96 OPERATION

1. Acce ss Procedure - an access procedure is included at the top of each page just be-

low the menu title. The access proce du re descri bes the keystro kes or other ac tio ns required to display this menu.

2. Sample Menu - a sample menu is outlined by a square. This sample shows the typical

contents of display area 4 when the menu is selected.

3. Menu Function - a menu function desc ribes the purpose of the menu.

4. Menu Operation - a menu operation describes how to use the men u.

5. Active Alpha Function Keys - an active alpha function key list is at the bottom of

each page. This list contains the alphabetical keys, active when the menu is displayed, that have been assign ed a predet ermi n ed softw are funct ion. The predet e rmine d software function of these alpha keys is described in the previous introductory Section 4.

5.2 Keyboard Operation

Depending u pon the display ed menu, the k eys most oft en used on the k eyboard are the numeric keys, en ter/ ret urn key, [ESC], and alphabetic func tio n keys.

5.2.1 Numeric Keys

The numeric ke ys are used to select a menu or transmitter parameter, or to enter a value into a da ta input f ield. T he num er i c k ey s o n the k eypad fun ction i denti ca lly to t hose on th e m ain keyboard if [NUM LOCK] is enabled.

5.2.2 Enter/Return Key

If the menu c ontain s a lis t of n umbered options, a sing le press o f a nu me ric k ey pro du ces the menu or function desired. No further keystrokes are required if the number pressed was one of the options.

If the menu contains a data input field, more than one keystroke is usually required to produce the desired function. Pressing numeric keys causes the value to appear in this data input field, in the space underlin ed by the curso r. The backspace key is function al during this procedure. After t yping a value into the data input field, a press of enter/re turn is required to activat e the value.

This key is labeled Enter, Return, or abbrev i ation s there o f, d epe n ding upon t he k e yboa rd. This key performs the same enter function regardless of label, and so is called [ENTER]. The key is used to activate a value that has been typed into a data input field.

When a data input field first ap pears, it alre ady co nta ins the defau lt val ue or th e last valu e entered by previous keyst rok e s. A cu rsor located to the left of this v al u e ind ic at es where a t yped numeral will appear. As the new value is typed into the data input field, the old value disappears and the cursor flows to t he right of the new value. After [ENTER] is pressed, the cursor re se ts to the lef t to ind ic at e the new valu e has be co m e the o pe rat ive val ue.

Page 28

Gold Line VDT Glenayre Document Number : 9110.00164 OPERATION Issue 1, Rev. F: 09/03/96

5.2.3 [Esc]

The [ESC], or escape ke y, is active when all except top-level menus are displa yed. Pressing the escape key cau ses the previous me nu to be displa yed. The p revious men u is the nexthigher le ve l, o r on e menu back. T he e sca pe key will no t w o rk if a M a i n Men u (remote or Local) is displayed.

5.2.4 Alphabetic Function Keys

Alphabetic fu nct ion k e ys a re a gro u p o f l etters th at, w hen pressed, cause a pred e termi ned activity to occur. Onl y some ke ys are active when a particular menu is displayed. An active alphabetic function key list is provided for each menu. The following is a list of all the alphabeti c function keys:

• M (disp lay main menu)

• R (refresh main menu)

• K (key or unkey TX)

• A (select all channe ls )

• Y (yes, perform req ue st)

• N (no, do not perform request)

• U (adjust value upw ard s)

• D (adjust va lue do wn w ard s)

M Key

Pressing the M (ma in m enu) ke y cau ses a main m enu t o be displ ayed, i f it is not a lready displayed. If the transmitter is in remot e control, the M key displa ys the Remote Cont rol Main Menu. If the transmitter is in local control, the M key displays the Local Control Main Menu.

R Key

Pressing the R (refresh) key causes a main menu to be displayed if it is not already displayed (the same as pressing the M key). The R key also causes the transmitter to update the status, currents, and powers valu es in the top ha lf of the scree n.

K Key

Pressing the K (key) key causes the trans mitter to key, if unkey ed, or to unkey, if already keyed. The K key is active in local control only. When local control is entered, the K key is activated and the transmitter unkeys, if already keyed. When local control is exited, the K key is deactivated and the transmitter assumes the key state determined by the remote ke y input.

A Key

Pressing th e A (all) key ca uses the chan nel-all menu to be displayed for the parameter presently selected . This key allows selection o r change of a transmitter para meter for all channels simultaneously, without having to select each channel individually.

7.3.1.1.1 Set Frequencies For Chan nel

Refer to following dia gram for ini tial steps of Set Frequenc ies For Cha nne l procedure .

Note

Different frequency ranges appear for different bands. The ranges which are available to y ou, correspo nd to the available frequency ran ge of the exciter, except in cases where the frequency band is subdivided (banded) so that frequencies selected must be within the range of resonant parts. For example, if your range is 920-960 MHz, you may legitimately selec t a new frequency around 925 MHz. The part icular exciter, howeve r, has resonant parts for, say, approximately 955 MHz and may not work at the programmed frequency because the VCO cannot lock unless you also install banded parts for the range which corresponds to the new frequency.

• Press numeric keys to input desired frequency into shaded area. Frequen cy must be

within limits and proper multiple as stated on screen. Frequency must be within bandwidth of VCO/RF amp li fier board. Press at least t hree whole di gits and no more th an eight dig i ts tot al . A de ci m a l may be pr e ssed if desired.

• Press Enter to store frequency and reset cursor. A decimal is assumed between third and
