Vertex Standard VX-6000L Manuale utente

Introduction

This manual provides technical information necessary

for servicing the VX-6000L FM Transceiver.

Servicing this equipment requires expertise in han-

dling surface-mount chip components. Attempts by non-

qualified persons to service this equipment may result in

permanent damage not covered by the warranty, and may

be illegal in some countries.

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.

Important Note

After Lot. 13 of this transceiver was assembled using Pb (lead) free solder, based on the RoHS specification.

Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this appara-

tus. The solder stated above utilizes the alloy composition required for compliance with the lead-free specification,

and any solder with the above alloy composition may be used.

DSUB 25-Pin Accessory Connector

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:

Pin 2, 3, 4, 5 & 6: SELECT, DSUB 03, DSUB 04, DSUB

05 & DSUB 06

These input port features can be programmed via

the CE49 programmer. The same item can not be

chosen twice.

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 VX-6000 includes a convenient “Clone” feature,

which allows the programming data from one trans-

ceiver to be transferred to another VX-6000. 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 MIC/SP jack on the transceiver.

Do this for both transceivers.

3. Connect the optional CT-72 cloning cable be-

tween the MIC/SP jacks of the two transceivers.

4. On the Destination transceiver, press and hold

the PF Button (just below the POWER Button)

while turning the transceiver on.

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

the Button 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 CT-72. Replace the plastic cap

and its two mounting screws.

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

begin normal operation.

DealerProgramming of VTP-50 and F5D-14

These procedures are designed to be used by the installing technician after the VTP-50 and F5D-14 has

been installed in the transceiver. To program a VX-6000’s VTP-50 and F5D-14 board, you will need the

CT-71 programming interface cable, the CE26 Programming diskette, and an IBM PC/AT or PS/2-com-

patible 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

PF Button (just below the Button).
