The first 8 of the random frequencies can be accessed in parallel mode using the three programming pins RB1, 2 and 3. To access the rest of the channels, the serial programming mode is required. The channel change can be controlled through this serial input. The Windows® based software supplied with the SX500 transceiver allows both a new channel to be selected as well as the re-programming of the internal frequency information. The software can be run on a PC with the serial port connected to PL3 of the SX500 transceiver via a suitable adaptor as shown in Figure 2. If the internal stored data is to be accessed, the read-back function is desired, then PL3 pin 13 of the transceiver must be connected to pin 2 of the PC serial port via a buffer circuit. A 1k pull-up resistor to +5V must also be provided as shown. Software Installation Figure 2 Programming Adaptor The s/w is installed by following the normal procedures for installing windows based software. Insert CD or the first floppy disk and run the “setup.exe” program. Follow the on-screen instructions and the s/w will be installed into the c:\program files\sx500 directory (WIN98) or c:\programs\sx500 (WIN95) directories. A program icon will be placed in the s/w group designated during the installation routine. Running the Software The s/w is accessed after installing by a single click on the SX500 icon. A screen page as shown in the following figure will be displayed. All functions are accessed through this screen. The fields shown in colour can be accessed and modified. Those field shown in grey are fixed by the hardware of the SX500 and cannot be changed by the user. Data is accessed by moving through the fields using the mouse or the TAB key. Where data can be modified, a short description of the data is shown at the bottom of the screen as an aide-memoir. There are 4 main areas of the screen plus the drop-down menu buttons at the top of the screen. The default settings of the screen give the user access to the common data to be modified through these four areas: Random Channel Table This gives access to the first 24 channels which can be set to any random frequency. Sequential Channel Table This gives access to the 232 channels which can only be sequential Current Settings This sets up the program parameters Unit Program Commands This area sets up the data transfer to and from the SX500 Top Level Menu File Load Load a pre-stored set of data. A file list is displayed which can be selected and loaded by using the mouse, highlighting and double clicking. Save Save the current set of data A set of directories are displayed. When in the correct directory, over-write the default file name displayed and click or hot. Print Print the current set of data. The currently selected Windows default printer will be used. Exit Exit the program. View Internal EEPROM Contents This displays in a separate window the contents of the units EEPROM. The data displayed is for the functions and channels displayed on the main screen at that time. Data can be hand-modified by moving highlighting the data and over-writing it. THIS SHOULD ONLY BE CARRIED OUT WITH FULL KNOWLEDGE OF THE INTERNAL WORKING OF THE SX500. Note that the type of data in each field is displayed at the bottom of the window. While this window is displayed, no access is available to the main screen. The window must be cleared down by clearing the “tick” in the View drop-down menu. Unit Settings only displayed when the Readback function has been used to download the PIC Code contents of the EEPROM. Current Settings Data COM port Select the correct serial port for the connection to the SX500, default COM1. Intermediate Frequency The Intermediate Frequency is fixed by the hardware and cannot be accessed Fosc The oscillator frequency is fixed by the hardware and cannot be accessed. Comparison Freq. (Fc) The channel step size is fixed by the hardware at 12.5 kHz. For 25kHz or other channel spacings, set the Table Step size accordingly. Minimum Frequency The minimum frequency is used by the software as a baseline for all other frequency information. This frequency is determined by the physical build of the unit and how it has been aligned. The s/w will not allow a frequency below this minimum to be selected. This frequency is stored in the nonvolatile EEPROM in the unit. Maximum Frequency The maximum frequency that the unit can work on is determined by the physical build of the unit and the alignment of the unit. If a frequency outside the alignment band is selected then the operation of the SX500 will no longer be to the stated specification. The maximum switching frequency over which the unit will operate is 5MHz. The software uses this 5MHz limit to calculate the maximum frequency from the minimum set and uses this for the selectable frequencies in the drop-down list displayed when selecting frequencies. This 5 MHZ band can be different for the transmit and receive frequencies. Receiver Offset The normal operation of the SX500 is with the transmit and receive frequency the same. If an offset is required, a fixed offset can be made between the frequencies by doubleclicking to bring up a selection of offsets. If a frequency outside the alignment band is selected then the operation of the SX500 will no longer be to the stated specification Max. Channel Number This number will determine how many sequential channels are programmed into the table. Serial/Parallel To ensure the correct operation of the unit after programming set this flag accordingly. After programming the unit the serial or parallel mode will be set according to this selection. Serial Channel No. To change channel select a new channel number by rightclicking to bring up a list or double-clicking to select the field to modify. Random Channel Table The first 24 channels of the SX500 can store randomly selected channels, which are nonsequential or separated by a common gap. To change an existing frequency, double-click the particular channel. Either type in a new frequency or select from a displayed list of allowed frequencies. Sequential Channel Table To program these frequencies, ensure that the Max. Channel Number field in the “Current Settings” is set correctly. Under the “Sequential Channel Table” area enter the start frequency and the Table Step size to set the frequencies in the table. Unit Programming Commands To access these 4 functions, double-click on the text or highlight and press ENTER. When accessed, the relevant data areas on the other three screen areas are highlighted to show which data is being transferred. Set parallel ch. mode Changes the SX500 from serial channel selection mode to/from parallel. Read from the unit Download the data from the SX500, assuming that the correct interface lead has been made. Se nd all the data displayed on the screen to the unit.

Parallel Channel Selection Three inputs RB1, RB2 and RB3 applied to PL3 pins 11, 12 and 13 respectively, select the operating channel as shown in the following table: CHANNEL SELECTION Most Significant Bit Least Significant Bit CHANNEL PIN 13 PIN 12 PIN 11 LOW LOW LOW LOW LOW HIGH LOW HIGH LOW LOW HIGH HIGH HIGH LOW LOW HIGH LOW HIGH HIGH HIGH LOW HIGH HIGH HIGH The logic levels are: LOW = < 0.8V, HIGH = > 2V or floating TECHNICAL SPECIFICATION Transceiver (Overall) Frequency Range 400 - 500 MHz (banded) Switching Bandwidth 5MHz Channel Spacing 12.5, 20 and 25 kHz Number of RF Channels 255 Frequency Stability ±2.5ppm Supply Voltage 5.5 - 15 VDC Supply Current Transmit Receive selectable with an external 3 line select selectable via a serial interface 32 random and 255 sequential <100mA at 7.2 VDC < 40mA at 7.2 VDC Duty Cycle 100% max Interface Connections Refer to Figure 1 RF Connection Via PCB Pins Size 59.5 l x 38.5 w x 17.0 h mm Weight • 30gms Temperature (operating) -25°C +55°C Temperature (storage) -30°C +80°C Approvals ETS 300 220, ETS 300 683, meets FCC & IC Transmitter RF Output Power 100mW +1, -2 dB adjustable down to 1mW Receive to Transmit Switching Time <25ms Power-on settling time <60ms Modulation Input Analog : Digital: Frequency Response <10 - 3000 Hz flat (at -3dB) 750 mV p-p nominal DC coupled TTL compatible Receiver Sensitivity -115dBm/12dB SINAD at 25kHz channel spacing AF Output 250mV p-p into 10kS (muted by Squelch) RSSI Output 0.5 - 2.0V with 60dB range and 33kS o/p impedance Squelch Type Noise operated with hysteresis.
