Maintenance 5- 26 4.1 GENERAL DISCUSSION The 2888 radio is a half duplex transceiver intended for use as either a Master or a Remote Station Radio unit in a Wireless SCADA data transmission system. 4.2 MICROPROCESSOR OPERATION The microprocessor, U-203 is the "brain" of the 2888 radio. It enables a computer to communicate with the 2888 radio and enables the operator to "see" everything that the Remote "sees", such as diagnostics. The microprocessor also allows the operator to observe the operating parameters, frequency, power output, reverse power, PLL voltages, the power output level and the frequency offset. These and other operations may be performed locally or through the RF link. 4.3 FUNCTIONS OF THE 2888 RADIO The Alligator Model 2888 offers diagnostic parameters which aid the user in troubleshooting potential problems in the SCADA network. The Model 2888 also offers options which enable the radio to be a “smart” radio. It may also be configured for use in a variety of different configurations. The Alligator Advanced Diagnostics Software can read and/or modify all of the following parameters for each responding Model 2888 Radio. 4.3.1 Diagnostic Parameters Parameter Description Alarm Status Alerts the user that one or more of the diagnostic parameters are not within the safety limits. Received Signal Strength Indicator (RSSI) An indicator of a Remote’s signal strength. Forward Power The amount of power the carrier frequency is being transmitted. Reverse Power An indicator of the quality of the Remote Radio’s antenna. A reverse power reading greater than one-third of the forward power reading indicates that the antenna is degrading, or that cables and connectors are not properly connected to the radio. 4.0 Theory of Operation Maintenance 5- 27 Parameter Description Supply Voltage The recommended power supply to the Remote Radio should be no less than 11 V and no more than 16V, with 13.8V the nominal voltage. A power supply capable of supplying at least 2 amps is required for proper operation of the radio. PLL Voltages The voltage readings of the two Phase-Locked-Loops (PLL1 & PLL2). For safe radio operation, this voltage should be between 0.1 to 4 Volts. Internal Temperature Serves as a “thermometer” for the environment surrounding the radio. Also serves as a sign if something is wrong with the Remote Radio. Table 4.2 Diagnostic Parameters Descriptions 4.3.2 Alarm Limits and Conditions The Alligator Advanced Diagnostics Software provides the user with the capability to set the desired safety limits for each diagnostic parameter. The user can set high and low limits for Supply Voltage, PLL1 Voltage, PLL2 Voltage, Internal Temperature, Forward Power, and event (squelch, PTT, Time- out) counters. Should any of these parameters fall outside its safety limits, an alarm condition will be generated and displayed by the Remote Radio. An alarm condition will also exist if the Reverse Power (reflected power) reading exceeds 30% of the Forward Power reading, or if the VSWR (Voltage Standing Wave Ratio) reaches an unsafe value. 4.3.3 Operating Parameters The Alligator Advanced Diagnostics Software enables the user to configure each Remote Radio to operate in a certain configuration. Each Remote Radio can be configured to operate under any of the following configurations: Parameter Description PTT Dekey Time (0-255 msec) Whenever the 2888 Radio turns on its transmitter, the dekey time is the number of milliseconds the transmitter stay…
