NXLXCVR3000900 MHz Scoreboard Transmitter

SETUP & OPERATION INSTRUCTIONS NXLXCVR3000 900 MHz WIRELESS CONTROL Connecting The Transmitter IMPORTANT FCC STATEMENTS 1. Connect the transmitter’s interface cable to the 8-pin female end of the adapter cable, then plug the 5-pin male end of the adapter cable into either of the controller’s control cable jacks. (See Figure 1) 2. Supply power to the controller using the supplied 12- volt DC wall transformer. Connect the transformer to the power receptacle on the back of the controller before plugging the wall transformer into a live outlet. (See Figure 1) 3. Turn the controller’s POWER switch ON. When the POWER switch is turned ON the controller’s LCD will read: To Continue Last Game Press Enter To Start New Game Press Reset Pressing either ENTER or RESET will enter the controller’s game mode. From here, the operator can begin scoring the game or enter the option menu where the game may be changed and keyboard options such as contrast and clock functions may be set. For complete and detailed operating instructions for your scoreboard model(s), please refer to the OPERATION MANUAL included with the scoreboard(s).

Operating Description This transceiver device can operate in half duplex mode on 16 different frequencies in the 902-928MHZ ISM band. While it is frequency agile, it does not actively “hop” between frequencies. The particular channel, or frequency is set via the serial link. The transceiver IC uses the 14.7456MHZ crystal as a reference for the PLL. Based on information coming in the serial channel, the microcontroller will set the operating frequency and mode (RX or TX). After this, the microcontroller is tasked with the baseband data exchange, usually via the RS485 link. For transmitter operation the transceiver’s PLL is programmed to the desired frequency and the RF data is FSK modulated (30KHZ typical frequency deviation) out the TX signal path shown in the block diagram. The microcontroller also drives the antenna switch to connect the TX output of the transceiver to the SAW filter. The filter reduces harmonics and any other spurious emissions before the signal is applied to the antenna. The exact frequency that corresponds to each of the channels is shown in the table below. For receiver operation the transceivers PLL is programmed to 150KHZ below the desired reception frequency (see table below). The IF is therefore approximately 150KHZ but exists only within the silicon of the transceiver. There is no external IF signal or filter. The microcontroller puts the transceiver in receive mode, and drives the antenna switch so that the RX signal path is chosen. In this mode the SAW filter is used to increase the selectivity of the receiver and decrease the possibility of blocking.
