VERTEX STANDARD VX-2100 (03) PDF MANUAL

Servicing this equipment requires expertise in handling 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.

The advanced microprocessor design allows a complete alignment of this transceiver to be performed without opening the case of the radio. All adjustments can be performed from a personal computer, using the Vertex Standard VPL-1 Programming Cable and CE82 Software.

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 apparatus. 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.

Pin 1 is the External Microphone Input (Analog Input). The nominal input level is 6 mV at 600-ohm. When connecting an External Microphone to this port, insert a 0.1 µF coupling capacitor between the microphone and this port.

Pin 2 provides a low-level receiver output (Analog Output). The peak signal level is 150 mV at 600-ohm.

Pin 3 is the ground for all logic levels and power supply return.

Pin 4 provides a switched 13.6V DC output for supplying power to an accessory.

Pin 5 provides a DC voltage proportional to the strength of the signal currently being received (Receiver Signal Strength Indicator) (Analog Output). This low impedance output is generated by the receiver IF sub-system and buffered by an internal op-amp. Typical output voltages are 1 V (@No Signal Input) through 2.0 V (@50 dB Signal Input).

Shorting Pin 6 to ground causes the transceiver to be placed in the Transmit mode. Opening the connection to this port returns the transceiver to the Receive mode. Opening voltage is 5 V, closed current approx. 5 mA.

Pin 7 is intended for controlling an external TX/RX switching circuit. This port is an open collector output which can sink approx. 100 mA when active. Max. voltage is 16V.

Pin 8 is used for the Ignition Sense feature. The VX-2100/-2200 may be automatically switched to the STND-BY mode when the vehicle’s ignition key is turned on. Maximum current is 20 mA.

These port features can be programmed via the CE82 programmer. Each port is an open collector output which can sink approx. 100 mA when active. Max. output 16V. When the input is selected, it becomes active between 2V and 16V.

Pin 13 (Accessory Port 5) is available to set only for Output function, and its active logic is the opposite side against Ports 1 ~ 4. It is a CMOS output with Max. output 5V, closed current approx. 1 mA.

Pin 14 (Accessory Port 6) is available to set only for Input function, and its active logic is the opposite side against Ports 1 ~ 4. It is a CMOS input with Max. input 5V.

Pin 15 is the Chassis ground.

There are 13 levels of squelch setting from 0 to 12.

Level 0 means open the squelch.

Level 1 means the threshold setting level.

Level 11 means tight squelch.

Levels 2 to 10 are established in the middle of threshold and tight. The bigger figure is nearer the tight setting.

Level 12 becomes the setting of carrier squelch.

The noise squelch circuit uses a band pass filter (Q1036), noise amplifier (Q1047), and noise detectors (D1047, D1048). When no carrier is received, noise from the demodulator (Q1036) is amplified, detected into a DC voltage, and sent to the CPU (Q1065). This DC voltage is “HIGH”. When a carrier is received, noise is compressed, and the DC voltage becomes “LOW”. If the voltage is HIGH, the CPU mutes the AF output (Q1044 OFF). If the voltage is LOW, the CPU enables the AF output (Q1044 ON).

The CPU (Q1065) detects the RSSI voltage output from Pin 12 of the IF IC (Q1036) to control the AF output. The RSSI voltage increases with stronger carrier signal strength. The process of AF signal control (muting/unmuting via Q1044) is the same as Noise Squelch. The shipping data is adjusted 3dB higher than squelch tight sensitivity.

The output power of the Power Module is detected by a CM coupler and diodes (D1007, D1008). This signal is input to a comparator (Q1048) which compares two different voltages and stabilizes the output power by controlling the bias voltage of the power module.

There are 3 levels of output power (Hi, Mid, and Lo) which are switched by the voltage of Q1014-CH1 (M62364FP). (Note: An E-Low level is also mentioned in the TX Power alignment section).

The PLL serial data from the CPU Q1065 is sent to the PLL IC Q1054 via three lines: SDO (pin 12), SCK (pin 11), and PSTB (pin 13). The lock condition of the PLL is output from the UL (pin 14) terminal. The CPU monitors the UL condition; if it becomes “L” (unlocked), the CPU prohibits transmitting and receiving.

The transceiver is aligned at the factory and realignment should not be necessary except in the event of a component failure. If damage occurs and parts are replaced, realignment may be required. Realignment should only be done after the cause of a malfunction is clearly pinpointed, faulty components are replaced, and the need for realignment is determined to be absolutely necessary.

Servicing and alignment should be performed only by authorized Vertex Standard service technicians who are experienced with the circuitry and fully equipped for repair and alignment. All component replacement and service should be performed only by an authorized Vertex Standard representative, or the warranty policy may be voided.

A 50-ohm RF Dummy load and in-line wattmeter must be connected to the main antenna jack during transmission, except where specified otherwise.

Because of the BTL (Bridged TransLess) Amplifier circuit, do not connect either side of the speaker leads to chassis “ground.”

Remove test equipment not needed for the next step before proceeding.

Ensure ambient temperature is the same for the transceiver and test equipment, held constant between 68 °F and 86 °F (20 °C ~ 30 °C).

Allow the transceiver to come to room temperature if brought in from hot or cold air.

Whenever possible, perform alignments with oscillator shields and circuit boards firmly affixed.

Test equipment must be thoroughly warmed up before beginning.

Follow all steps in a section in the order presented. Do not attempt only a single step unless it is clearly isolated electrically.
