Chapter 1 Product Overview Introduction Thermo Electron Corporation’s AutoRADIO Wireless Modem is a synchronized wireless networking system. Each radio in the network is a half-duplex radio with frequency hopping spread spectrum features. In transmit mode, the base band receives data from an upper level data source and packetizes it into data packets. After adding the 16-bit CRC check, the radio is set to TX mode, and the PA is ramped up to the power level controlled by the ARM processor. The data train is then Gaussian filtered to reduce bandwidth occupation. The filtered pulse train modulates the frequency (FSK) generated by VCO and then converts to the desired frequency. The RF signal is then amplified to approximately 5 dBm. Frequency control is accomplished by the on-chip synthesizer, and the RF signal is then filtered to remove harmonics via a band pass filter. The radio hops frequency at a rate of 25 ms per hop. In the receiving mode, the radio signal coming from the antenna is filtered by the band pass filter and amplified by a low-noise amplifier (LNA). After one conversion, the data is demodulated by an on-chip FM demodulator. The on-chip clock recovery circuits recover the clock from the received signal. The recovered data is then fed to the ARM processor. A Baker code controls the frequency hopping pattern. Within the ISM band, there are 51 hops in each cycle. The radio also comes with RSSI, automatic gain control, and data retransmission features. Following is an overview of the instrument: Thermo Electron Corporation ● Wireless, license-free FHSS modem ● Operates on the 902–928 MHz frequency band ● 16-bit CRC check for data integrity ● Nested private network ● Built-in diagnostic information ● Same footprint as Thermo’s AutoWAVE ● Low power ● Software performance optimization, no tweaking or manual adjustment AutoRADIO User Guide 1-1 Product Overview Modes of Operation Modes of Operation ● Friendly hardware and software user interface ● Maintenance free 1. Normal mode: Radios are defaulted to work as point-to-multipoint. A network consists of a master radio broadcasting to multiple slaves and/or repeaters. Any two radios in this network may also be set up as private network or point-to-point using AT command set to dial the other radio ID. Once this link is established, these two radios will reject all data from the master or from the repeater radio. The radios will return to point-to-multipoint mode as soon as disconnect AT command is issued. 2. Boot Loader mode: With proper shorting on block JP3, the radio goes into the boot loader mode, allowing for the radio firmware upgrade function.

Chapter 2 Installation Transceiver Transceiver location typically has a significant impact on the instrument’s performance. In general, higher placement of the antenna ensures a better communication link. Additionally, the transceiver should be placed away from computers, telephones, answering machines, and other similar equipment. Placement of the external antenna is critical to a solid data link. Other antennas in close proximity are a potential source of interference. It is also possible that slight adjustments in antenna placement will solve noise problems. Power output of the radio system, including the antenna gain, cable loss, and insertion loss, should not exceed 36 dB. Software Thermo Electron Corporation To install the software, the operating system must be running Microsoft® Windows® 98/NT/2000/XP (English versions). Insert the CD into the appropriate drive. The CD should automatically start. Follow the directions as they appear on the screen. AutoRADIO User Guide 2-1 This page intentionally left blank. Chapter 3 Set Up Hardware Configuration 1. Install the antenna to the radio board. 2. Apply power to the radio via the 2-position .200” connector on the serial PC cable. Observe polarity. 3. Connect the diagnostic cable from the PC to JP2 (see Figure 1–1). Software Startup Using the AutoRADIO startup software, you can fine tune certain parameters in order to optimize performance.

On the following screen, click the Search Connected Radio tab, and the screen displays information pertaining to the connected instrument. Thermo Electron Corporation AutoRADIO User Guide 3-1 Set Up Basic Configuration Figure 3–2. Basic Configuration From the screen shown in Figure 3–2, you can load the default configuration or a previously saved configuration. You can also edit the following parameters: 1. Radio Network ID: Enter a number from 1–255 for the radio network. The network ID enables slaves to identify and communicate only with masters or repeaters within the same network. 2. Station Type a. Master Station: Designate this instrument as the master that maintains network timing synchronization and broadcasts data to all radios in its subnet or cell. b. Slave Station: Designate the instrument as a slave within the network that responds to a network master or a repeater radio. c. Repeater Station: Designate the instrument as a repeater within the network. A repeater radio acts as a repeater by relaying data from the master radio or from another repeater radio; it also acts as a slave in a network. The repeater is used to increase coverage or distance to route radio signals around natural or manmade obstructions. 3. Station Name: Enter a name that enables you to easily identify the installed location. You can enter a maximum of 23 characters. 3-2 AutoRADIO User Guide Thermo Electron Corporation Set Up Basic Configuration 4. Radio ID: Enter a number from 1–65535 which identifies the radio. The assigned ID should be unique for every radio within a radio network. The maximum number of radios in the network is 65535. 5. Subnet Address: For master and slave stations, this is the number assigned to all radios within a particular cell. For repeater stations, it is the number of the cell to which the radio is relaying data. 6. Parent Subnet: This field is only selectable if you have set the radio as a repeater. A repeater radio relays data from a master or a repeater radio that has a matching subnet number with its parent subnet. 7. Hopping Key: This field is only selectable if you have set the radio as a repeater. Enter a number from 1–50. The default setting is 1. It is very important that the hopping key is different for every repeater located in the same cell with the master. The different hopping key will ensure that only repeater transmits in any instance. Use these guidelines to help you set a hopping key: a. Within the master radio cell, select a unique hopping key (1–25) for each of the repeaters. b. Select a hopping key (1–50) for any repeaters in a subsequent cell. c. Repeaters in subsequent cells may have the same hopping key. 8. Turn off LED: Enable this power-saving feature by clicking the check box. The 3 status indicator LEDs will turn off if checked. 9. Password: Click this button to enter or change a password. The default password field is none. A password is not required to configure the radio; however, if one is used, store it in a safe place where it can be retrieved if forgotten. Contact Thermo’s engineering department if you need to reset the password. The radio configuration profile (filename.cfg) is needed for this task. 10. Uart Baud Rate: Select the baud rate of the data interface port, 115.2 Kbps maximum. 11. Data Bits: This selection applies to the data interface port. Thermo Electron Corporation AutoRADIO User Guide 3-3 Set Up Advanced Configuration 12. Parity: This selection applies to the data interface port. 13. Stop Bits: This selection applies to the data interface port. 14. Uart mode: Select between serial RS232 or 4-wire RS485. 15. You can now save this configuration by clicking the Save As button, or you can click the Advanced button to access additional parameters. Advanced Configuration Figure 3–3. 3-4 AutoRADIO User Guide Thermo Electron Corporation Set Up Advanced Configuration 1. Broadcast Retry: You can set the radio to attempt up to 8 retries. 2. Synchronization Timeout: You can set this field from 250–500 ms with 50 ms increments. This setting applies to the repeater and slave radios only. The repeater or slave radio will start the synchronization procedure and scan for the master once it is out of sync with the master for this amount of time. 3. Force a join with the specified parent subnet: This field is only available if the radio is set as a slave station. If not selected, the slave radio will try to talk to any repeater or master in a network. 4. Enable power save channel scan: This field is available if the radio is set as a slave or repeater station. If the radio loses sync with the master, it begins to continuously scan for the master signal. Enabling this feature allows you to set the radio to scan only at specified intervals (0–60 s). 5. Enable Deep Sleep Mode: This field is available only if the radio is set as a slave station. This feature causes the radio to power down once it has completed its transmission. Insert an RS232 space signal on RTS pin to bring the radio out of sleep mode. 6. Packet Size: Designate the size of the data packets used by the radio in its transmission. In noisy environments, it is often beneficial to use smaller data packet sizes to increase the chance that data is received at the other end. 7. Radio Transmit Power: Reducing the transmit power ensures that the radios do not overwhelm each other when used in close proximity. Follow these guidelines when setting radio transmit power: Table 3–1. Radio transmit power settings Thermo Electron Corporation Setting Power Level Used 10 dbm Low Pair or pairs of radios operating within the same or adjoining rooms 20 dbm Medium More than one pair operating within the same facility 30 dbm Full Normal operation extending beyond a facility AutoRADIO User Guide 3-5 This page intentionally left blank.
