5. Library Setup and Configuration Once installed you can use a PC to connect to the Tracker2 either the Windows configuration program otwincfg exe or a terminal emulation program of your choice such as Hyper Terminal or SecureCRT Note that the radio must be in data mode to power up the TNC board To use the command console connect at the proper baud rate 4800 baud is the default and press enter several times until you see a command prompt To use the Windows configuration program simply start the program select the COM port and set the radio to data mode The only setting absolutely required for normal APRS tracker operation is the callsign The defaults for all other settings should be reasonable but you should check on locally recommended settings particularly for the digipeater path Command Reference 1WIREWX Enables 1 Wire Weather Station mode The TAI8515 weather station should be connected to pins 8 data and 5 ground of the rear panel d sub connector ABAUD 1200 2400 4800 9600 19200 38400 57600 115200 Sets baud rate for the primary serial port rear panel d sub on the DR 135 Default is 4800 baud ALIAS lt n gt lt callsign gt Sets digipeater alias for slot lt n gt This will typically be a generic alias like WIDE No SSID is allowed in this field ALTITUDE on off Report altitude in position packet AMODE AUTO GARMIN KISS WS2300 Sets mode for primary serial port AUTO mode automatica

7. he KISS protocol defines an interface between a TNC and its host typically a PC This mode allows the Tracker2 to be used with PC based APRS programs like Xastir WinAPRS and UI View32 It can also be used with non APRS applications subject to the limitations of the Tracker2 s transmit and receive buffers Digipeater A digipeater acts as a simplex digital repeater receiving packets and retransmit ting them typically on the same radio channel The Tracker2 s digipeater function is designed specifically for APRS use and supports advanced features such as WIDEn N operation hop count limiting duplicate elimination preemptive digipeating and multiple aliases Weather Station The Tracker2 can be connected to several models of weather station including the Peet Bros Ultimeter 2000 series Dallas AAG 1 Wire Weather Station and LaCrosse WS 2310 wireless weather station to provide remote weather telemetry Command Console While the Tracker2 comes with a Windows based configuration program it can also be configured tuned and upgraded through a traditional console interface with command syntax similar to that of the classic TNC2 and its clones Keyboard to keyboard QSOs are supported through a converse mode as well as APRS messaging commands From The N3UJ CQM Document Library Installation Installation of the T2 135 is identical to that of the EJ 41U TNC described in the DR 135 manual Remove the radio s bottom panel
8. ithm allows the tracker to operate more efficiently by changing how often it transmits depending on its speed and turn rate When stopped or moving at a speed below the low speed setting the tracker will transmit at a fixed rate determined by the lower rate setting Above the specified high speed threshold the higher rate setting is used Between these two extremes the interval varies between the low rate and high rate specified separately with the INTERVAL command depending on the speed The lt low speed gt and lt high speed gt settings define these two limits For storage efficiency the speeds are represented in units of 32 centimeters second To convert from miles per hour multiply by 1 397 To convert from kilometers per hour divide by 1 152 Setting MPH Km h 5 3 6 5 7 10 Tee 11 5 15 10 7 17 25 17 9 29 40 28 6 46 60 43 69 80 57 92 100 71 115 lt low rate gt and lt high rate gt are specified in seconds lt angle gt indicates the change of direction in degrees that will cause an immediate transmission lt time gt specifies in seconds the minimum time required between transmissions regardless of speed or turns SQUAWK lt 0 255 gt seconds Transmits alternating tones for specified number of seconds May be used for testing or direction finding From The N3UJ CQM Document Library SWDCD on off Enable software data carrier detect mode Forced on for T2 135 STATUS lt 0 255 gt Interval between sta
