Vertex Standard VX-6000U Manuale utente

Introduction

This manual provides technical information necessary for

servicing the VX-6000U UHF FM Transceiver.

Servicing this equipment requires expertise in handling sur-

face-mount chip components. Attempts by non-qualified per-

sons to service this equipment may result in permanent damage

not covered by the warranty, and may be illegal in some coun-

tries.

Two PCB layout diagrams are provided for each double-sided circuit board in the Transceiver. Each side of is referred

to by the type of the majority of components installed on that side (“leaded” or “chip-only”). In most cases one side has

only chip components, and the other has either a mixture of both chip and leaded components (trimmers, coils, electrolytic

capacitors, ICs, etc.), or leaded components only.

While we believe the technical information in this manual to be correct, VERTEX STANDARD assumes no liability

for damage that may occur as a result of typographical or other errors that may be present. Your cooperation in pointing

out any inconsistencies in the technical information would be appreciated.

Pin 1: RSSI [Analog Output]

A DC voltage proportional to the strength of the

signal currently being received (Receiver Signal

Strength Indicator) is provided on this pin. This

low impedance output is generated by the receiver

IF sub-system and buffered by an internal op-

amp. Typical voltages are graphed as follows:

Similarly, if you assign “CH SW0,” “CH SW1,”

and “CH SW2” to the Universal Input Port, you

can recall Channels 1~7 as shown below:

If you need to recall all memory channels (15 CH)

from the External Controller via the Uni-versal

Input Port, you should assign the “All Channel

Recall” Command (CH SW 0 ~ CH SW 3) to the

Universal Input Port.

In this case:

The Memory Channel is determined via the CE49

Programmer. (Common DSUB-25pin connec-

tor Channel switch Table).

Cloning

The includes a convenient “Clone” feature,

which allows the programming data from one trans-

ceiver to be transferred to another . Here is

the procedure for Cloning one radio’s data to anoth-

er.

Note: When a cloning isn't made, you correct the fol-

lowing part using “CE49."

When a “Radio to Radio Clone" which is in the

“Miscellaneous" menu is “Disabled," change this

menu to “Enabled."

1. Turn both transceivers off.

2. Remove the plastic cap and its two mounting

screws from the jack on the transceiver.

Do this for both transceivers.

3. Connect the optional cloning cable be-

tween the jacks of the two transceivers.

4. On the Destination transceiver, press and hold

the (just below the )

while turning the transceiver on.

5. Now, on the source transceiver, press and hold

the while turning the transceiver

on.Data will now be transferred to the Destina-

tion transceiver from the source transceiver.

6. If there is a problem during the cloning process,

sound an error beep from source the transceiver.

Check your cable connections and battery volt-

age, and try again.

7. If cloning is a successful, turn the Destination

transceiver off. Now turn the source transceiver

off.

8. Disconnect the . Replace the plastic cap

and its two mounting screws.

9. You can then turn the transceivers back on, and

begin normal operation.

Dealer Programming of VTP-50 and F5D-14

These procedures are designed to be used by the installing technician after the and has

been installed in the transceiver. To program a 's and board, you will need the

programming interface cable, the Programming diskette, and an IBM PC/AT or PS/2-

compatible type computer.

To enter the Programming mode, use the follow-

ing procedure:

1. Turn the transceiver off.

2. Turn on the transceiver while holding in the

(just below the ).
