QUICK SET UP AND OPERATION Synching Up the Transmitter and Base The synch operation only needs to be performed the first time a system is used, or a new bodypack is used with a base previously synched to another bodypack. Do not perform the synch operation multiple times; it only needs to be done one time when a new bodypack is used with a new base. 1) Turn the transmitter power switch to ON and place the transmitter in the recharge cradle of the base. The transmitter goes in the base with the belt clip facing out. 2) The recharge LED will light (Green if fully charged, Red if charging). Leave the transmitter in the cradle for 4 hours for a full charge. 3) Press the REC button on the transmitter and hold until the In-Use LED on the transmitter and base start to flash, then release the button. 4) After a few seconds the light will stop flashing, and a beep will sound (If the beep is enabled). 5) The transmitter and base are now synched and will continue to be until another transmitter is linked to that base. Normal Operation 1) With the transmitter synched up, remove it from the cradle, plug in the lapel microphone (if used) and place the transmitter on your belt. 2) When you remove Transmitter from the cradle, The TR and Base’s In-USE LED will light a constant Green and you will hear short beep. To start the recording, press the REC button and the In-Use LED will blink in green. 3) To end recording, press the REC button and the In-Use LED will light a constant green. 4) At the end of your shift turn the transmitter off and replace it in the charging cradle. Out of Range 1) The transmitter will alert you with Audible warning beeps (two tone) and the In-Use LED will blink in red. 2) Move closer to the receiver base and the link will be re-established once you return to normal range. The In-Use LED will light constant green when link is back to normal operation. 3) If the link is not re-established within 30 seconds, the transmitter and receiver will return to standby mode. 4) If you went out of range in Standby mode, or the unit reverted to standby mode, re-enter normal range and press the In-Use button. Operation will return to normal. 5) If you will be out of range for a long period of time, turn the bodypack off. Low Battery Warning 1) If the transmitter Low BATT indicator (red) starts flashing or you hear warning beeps, return the transmitter to its cradle on the receiver to fully charge the transmitter. 2) The Charge LED indicator will light constant green when the unit is fully charged. EMG Panic Button (if wired for use in your vehicle) 1) The EMG or Panic Button can be programmed to do many things but may not be connected in your vehicle. Check with your technical department to understand what this button will control before you use it. 2) In Record mode: Press the EMG button on the transmitter, a beep will sound and the relay will be triggered at the receiver. 3) In Standby mode: Press the EMG button on the transmitter, a beep will sound, the green In-Use indicator will blink and the relay will be triggered at the receiver. Disabling the Beep Sound On the Transmitter 1) All of the audible beep signals on the transmitter can be disabled by setting the BEEP switch to the off position. Record Trigger (if video recording equipment supports) 1) The Record trigger feature is used to turn on recording whenever the video recorder is turned on. Some video record units can be triggered by other events (lights and siren being turned on etc.) and ensures the microphone starts recording at the same time. The transmitter must be turned on and in standby mode. 2) A +12V signal on the line means the microphone is Record off. 3) 0V or ground on the line turns on the microphone is Record on. 2.

The block diagram in figure 1 represents the RTX RF module. The baseband controller (NSC SC14408) controls the LMX by a Microwire interface and by other baseband signals. The interface is described in detail in section 2.7. LNA PAD LMX4x68 PA Power ramp SW1 SW2 Logic control Baseband controller PLL Loop filter Baseband controller Figure 1. Block diagram of RF module employing the LMX4268. Only two logic ports are used in the Reference Design Kit. The four logic ports are capable of controlling auxiliary circuits, such as activating the power amplifier (PA) and controlling the RX/TX switch. If preamble antenna diversity is to be employed, the baseband processor should control the antenna switches. Both the PA-driver and the LNA require balanced signals. Baluns must be placed at the LNA input and the PA driver output. It is recommended to have the schematics of the RTX module at hand before proceeding. 2.2 Front-end The RTX RF module has two antenna ports. Two PIN diodes controlled by the baseband processor are used for routing the desired antenna to the RX/TX path. Preamble antenna diversity, also known as fast antenna diversity, is supported by this solution. The LMX4268 also features built-in preamble antenna diversity, and has two output ports for driving the antenna switches. Using the bidirectional microwire interface, it can be read-back which antenna was chosen for a receive slot. That same antenna is usually selected for the following transmit slot. Mounting options determine the diversity function of the Kit. 2-Layer 2G4 RF Reference Design Page 6 of 16 This document and the information contained is property of RTX Telecom A/S, Denmark. Unauthorized copying is not allowed. The information in this document is believed to be correct at the time of writing. RTX Telecom A/S reserves the right at any time to change said content, circuitry and specifications. RX/TX switching is accomplished using two PIN diodes, one in the signal line from the power amplifier, and a shunt diode placed a quarter of a wavelength towards the LNA. Logic ports on the transceiver control the diodes. When the two diodes are forward biased, the PA signal is routed towards the antennas, and the shunt diode shorts the signal to ground. However, the quarter-wave microstrip transforms this short into a high-impedance load. This construction has the advantage of very low loss and low power consumption in receive mode. A band pass filter is used to protect the receiver from blocking signals and to attenuate certain spurious emissions, such as the 3 rd and 4 th harmonic of the VCO. For 2.4GHz ISM systems there are no formal requirements for receiver immunity to other systems. The LMX4268 receivers have some frequencies that are subject to blocking, namely the fundamental as well as the first harmonics of the VCO. Using band pass filters generally increases immunity to other systems, and gives a better product. To control the power envelope in transmit mode, the power amplifier supply voltage is switched. A logic port on the transceiver activates the supply power to the power amplifier. The used power amplifier has integrated switching. Ramping up or down the PA is prone to cause transient emissions or even frequency offsets of the VCO. By proper ramping of the supply voltage transients can be avoided, and shielding the transceiver circuit isolates the VCO from the field surrounding the module. 2.3 PLL synthesizer The integrated integer-N PLL uses the 10.368MHz clock signal supplied by the baseband chip as reference frequency. The phase detector operates at 432kHz, which gives a channel spacing of 864kHz, because the prescaler is connected to the VCO output at half the transmit frequency. Please refer to the data sheet for specific A- and B counter settings. The synthesizer requires an external loop filter between the charge pump output and the VCO tune input. The lock-in time of the PLL and open-loop drift depends on this filter. The LMX4268 uses open-loop modulation, where the gaussian shaped transmit signal is applied directly to the VCO modulation input. This implies tri-stating the charge pump when transmitting a burst of data. This also conveniently prohibits the front-end from transmitting any spurious emissions generated by the synthesizer. During the lock-in phase of the synthesizer, it is critical that the modulation input to the VCO is kept at the mean voltage of the modulation that will be applied during the actual transmission. If this is not the case, a frequency offset will be present. If the modulation input 2-Layer 2G4 RF Reference Design Page 7 of 16 This document and the information contained is property of RTX Telecom A/S, Denmark. Unauthorized copying is not allowed.

The 10.368MHz reference frequency is used by the digital circuitry as well as reference for the synthesizer. This means that the reference frequency cannot be switched off, even when the PLL is not active. 2.4 Power up, calibration and initialization After power up or reset, the chip must be calibrated and initialized. Calibrating IF filter response and DC-offset at the ADC input compensates for manufacturing tolerances. The calibration is fully autom…
