MAXON SD-125 RF LINK MODULE The MaxonCIC SD125E Series of RF Link Modules from MaxonCIC utilizes the latest technology in its design and manufacturing. Both the UHF and VHF models are PLL (Phase Lock Loop Synthesizer) / microprocessor controlled, and offer one to five watts of power with 16 channel capability. Multiple functions including 1200 to 9600 baud rates, AC and/or DC audio coupling, GMSK and FSK modulation are standard in these fully programmable wide bandwidth RF Link Module units. The radio is programmed using a IBM Personal Computer, DOSbased software, an interface module and a programming cable. This allows the radio to be tailored to meet the requirements of the individual user and of the System(s) it is operating within. Busy Channel Lockout 16 Channels TX Time-out Power Save 1 / 5 Watt Programmable Output 12.5 / 25 kHz Programmable Channel Spacing Busy Channel Lockout The Busy Channel Lockout feature, when enabled, disables the transmitter when the receiving channel is busy and the user attempts to transmit. 16 Channels The SD-125 Series radio can store up to 16 channels within the same band. TX Time-out The TX Time-out feature, when enabled, limits the amount of time that the user can continuously transmit. This time can be set in increments of 10 seconds from 10 seconds to 990 seconds. Power Save The Power Save feature is used when an external battery is used as the power source. When Power Save is enabled, the receiver “ON” and “OFF” time can be programmed into the radio and allows the operator to set the length of time the receiver is asleep. MAXON SD-125 RF LINK MODULE MAXON SD-125 RF LINK MODULE The SD125E Series radio requires the ACC-900E Programming Software, 9-15 VDC 200mA Power Supply and ACC2125 Programmer Interface Cable. Refer to the ACC-900E Programming for detailed information on programming the SD125E Series radio. The SD-125 UHF/VHF Receiver is by design, broad band covering UHF(400-430 MHz & 440-470 MHz & 470-490MHz) and VHF(148-174 MHz) and should require no special alignment, unless repairs are performed on the receiver portion. Should repairs be necessary, use the "Test Equipment Diagram" on page 17 & the "Alignment Points Diagram" on page 18, in conjunction with the following procedures: • An Extender Board is required in order to separate the Digital and RF PCB’s to allow access to the alignment points. Installation instructions are provided with the Extender Board Assembly. RECEIVER Apply a standard test signal to the receiver antenna terminals. Adjust T1 for maximum sensitivity and audio output with minimum audio distortion. Adjust RV403 for the specific audio output level. RX VCO Set the unit to the highest receive frequency, 470MHz(UHF), 174MHz(VHF) and adjust the VCO L303 to 8 volts. Set the unit to the lowest receive frequency 440MHz(UHF), 148(VHF) and check that the VCO voltage is above 2.0 volts. If voltage is below 2.0 volts, adjust L303 for 2.0 volts or more. • Note: Use TP1 to measure the voltage. TRANSMITTER Connect the unit to a Service Monitor with the power meter setting to the 10 W scale (or autorange) TCXO Set the channel selector to the mid-range frequency 460 MHz, adjust TCX01 for a reading of 460 MHz ±200Hz (155 MHz VHF models). TX VCO Set the unit to the highest transmit frequency, 470MHz(UHF), 174MHz(VHF) key the transmitter and adjust the VCO L203 to 8 volts. Set the unit to the lowest transmit frequency 440 MHz(UHF), 148(VHF) key the transmitter and check that the VCO voltage is above 2.0 volts. If voltage is below 2.0 volts, adjust L203 for 2.0 volts or more. • Note: use TP1 to measure the voltage. TX Deviation and Balance Adjustment Set the unit to a mid-frequency and input the TX data with 400 Hz standard audio level. Increase the signal level to 20 dB from standard level. Monitor the demodulated signal from service monitor. Adjust RV3 to make the monitored signal to be a balanced square wave. Reduce input signal to the standard level and adjust RV2 for the standard deviation. APC Adjust RV1 for High Power (5W) Adjust RV6 for Low Power (1W) This completes the transmitter alignment procedures. MAXON SD-125 RF LINK MODULE MAXON SD-125 RF LINK MODULE Surface Mount Components Surface mount components should always be replaced using a temperature controlled soldering system. The soldering tools may be either a temperature controlled soldering iron or a temperature controlled hot-air soldering station. A hot-air system is recommended for the removal of components on these boards. With either soldering system, a temperature of 700° F (371° C) should be maintained. The following procedures outline the removal and replacement of surface mount components. If a hot-air soldering system is employed, see the manufacturer’s operating instructions for detailed information on the use of your system. CAUTION: Avoid applying heat to the body of any surface mount component using standard soldering methods. Heat should be applied only to the metalized terminals of the components. Hot-air systems do not damage the components since the heat is quickly and evenly distributed to the external surface of the component. CAUTION: The CMOS Integrated Circuit devices used in this equipment can be destroyed by static discharges. Before handling one of these devices, service technicians should discharge themselves by touching the case of a bench test instrument that has a 3-prong power cord connected to an outlet with a known good earth ground. When soldering or desoldering a CMOS device, the soldering equipment should have a known good earth ground. Surface Mount Removal 1 Grip the component with tweezers or small needle nose pliers. Alternately heat the metalized terminal ends of the surface mount component with the soldering iron. If a hot-air system is used, direct the heat to the terminals of the component. Use extreme care with the soldering equipment to prevent damage to the printed circuit board (PCB) and the surrounding components. When the solder on all terminals is liquefied, gently remove the component. Excessive force may cause the PCB pads to separate from the board if all solder is not completely liquefied. It may be necessary to remove excess solder using a vacuum de-soldering tool or Solder wick . Again, use great care when de-soldering or soldering on the printed circuit boards. It may also be necessary to remove the epoxy adhesive that was under the surface mount component and any flux on the printed circuit board. Surface Mount Component Replacement “Tin” one terminal end of the new component and the corresponding pad of the PCB. Use as little solder as possible. Place the component on the PCB pads, observing proper polarity for capacitors, diodes, transistors, etc. Simultaneously touch the “tinned” terminal end and the “tinned” pad with the soldering iron. Slightly press the component down on the board as the solder liquefies. Solder all terminals, allowing the component time to cool between each application of heat. Do not apply heat for an excessive length of time and do not use excessive solder. With a hot-air system, apply hot air until all “tinned” areas are melted and the component is seated in place. It may be necessary to slightly press the component down on the board. Touch up the soldered connections with a standard soldering iron if needed. Do not use excessive solder. • CAUTION: Some chemicals may damage the internal and external plastic parts of the radio. 4. Allow the component and the board to cool and then remove all flux from the area using alcohol or another approved flux remover. Surface Mounted Integrated Circuit Replacement Soldering and de-soldering techniques of the surface mounted IC’s are similar to the above outlined procedures for the surface mounted chip components. Use extreme care and observe static precautions when removing or replacing the defective (or suspect) IC’s. This will prevent any damage to the printed circuit board or the surrounding circuitry. The hot-air soldering system is the best method of replacing surface mount IC’s. The IC’s can easily be removed and installed using the hot-air system. See the manufacturer’s instructions for complete details on tip selection and other operating instructions unique to your system. If a hot-air system is not available, the service technician may wish to clip the pins near the body of the defective IC and remove it. The pins can then be removed from the PCB with a standard soldering iron and tweezers, and the new IC installed following the Surface Mount Component Replacement procedures. it may not be necessary to “tin” all (or any) of the IC pins before the installation process.
