SECTION 3 PROGRAMMING Attenuator Spectrum Analyzer JSLM2 Set-up Cable 6-15VDC Figure 3-1 JSLM2 Field Programming Software Setup 3.1 INTRODUCTION 3.1.1 GENERAL Section 3 describes the use of the Field Programming Software used to configure and test the JSLM2 transceiver. Mechanical adjustments for frequency, deviation and audio levels are described in Section 4 (Alignment and Troubleshooting). This information is designed for use by installation personnel.
Figure 3-2 JSLM2 Field Programming Software Start-up Screen 3.2.2 RADIO PARAMETERS The Setup JSLM2 Parameters screen allows the user to view and edit the JSLM’s programmable parameters (see Figure 3-3). The programmable parameters can be stored in a data file with the .DAT file extension by selecting “Save Data File” from the file menu. These programmable parameters are used by the Read/Write Parameters screen for programming into nonvolatile memory of the JSLM2. 3.2.2.
Figure 3-3 Setup JSLM2 Parameters - Settings Tab Comment The Comment field can be used as a notepad (customer name, location, technical information...) for text up to 40 characters in length (including spaces). Date Last Configured Date Last Configured shows the date the JSLM2 was last programmed. The date is taken from the operating system. No entry is allowed in this field. Mic Mute Mic Mute allows the user to enable or disable the microphone audio input.
Rx De-emphasis Since data equipment normally requires a flat audio response, the default value for Rx De-emphasis is disabled (unchecked). With Rx De-emphasis disabled, the JSLM2 provides a 300 - 2500 Hz +1/-3 dB flat audio response. When the Rx De-emphasis is enabled (checked), data output is passed through a 300 Hz - 3000 Hz filter and a 6 dB per octave de-emphasis response.
Radio Parameters Radio The Radio drop-down box shows the type JSLM2 (UHF or VHF). The Radio type is uploaded from the JSLM2 or from an opened file. No entry is allowed in this field. Figure 3-4 Setup Radio Parameters Screen Range The Range drop down box shows the frequency range of the JSLM2. The frequency range is uploaded from the JSLM2 or from an opened file. No entry is allowed in this field. Synthesizer Type Shows the synthesizer type for the JSLM2. No entry is allowed in this field.
Carrier Detect On Threshold Carrier Detect On Threshold indicates the RSSI level for a received carrier. The Carrier Detect On Threshold value should be greater than (a less negative number) the Carrier Detect Off Threshold value. Carrier Detect Off Threshold Carrier Detect Off Threshold indicates the RSSI level for a lost carrier. The Carrier Detect Off Threshold value should be less than (a larger negative number) the Carrier Detect On Threshold value. 3.2.2.
Default Freqs The Default Freqs button returns the Rx and Tx frequencies to default values. The default frequencies are based on radio type and range. Default Power The Default Power button allows the user to return the Tx Power to factory power output settings. 3.2.3 VERSION REQUEST Figure 3-6 JSLM2 Version Request Version Request displays JSLM2 hardware and firmware version information. 3.2.
Figure 3-7 Serial PC Port Settings Screens 3.2.5 PORT SETTINGS Port Settings are used to configure the user PC’s serial COM ports (Primary and Secondary). Port Settings can be used to test data links using the ASCII and HEX terminals (available in the Utilities menu). The JSLM2 Field Programming Software will override these settings when using any other screen to communicate with the JSLM2. NOTE: A modem is required to transmit serial data using this program. The JSLM2 is an analog signal device.
DTR Enable The DTR field allows the user to select whether the DTR (Data Terminal Ready) line of the RS-232 port is asserted when the port is open for the Primary and Secondary COM ports. Mode Mode allows the user to select the communications mode for the Primary and Secondary COM ports. See Table 32 for available modes.
Swap COM Ports Swap COM Ports allows the user to swap the Primary and Secondary COM ports. For example, if the Primary is COM1 and the Secondary is COM2, the Primary becomes COM2 and the Secondary becomes COM1 after a Swap COM Ports is issued. This utility is useful when more than one JSLM2 is connected to a PC since the programming screens all use the Primary COM port. By issuing a Swap COM Ports, the JSLM2 connected to the second COM port can be programmed without switching cables. 3.2.
Bytes Tx’ed The Bytes Tx’ed field shows the number of bytes (characters) transmitted since the port was last opened. Bytes Rx’ed The Bytes Rx’ed field shows the number of bytes (characters) received since the port was last opened. Framing Errors The Framing Errors field shows the number of Framing Errors received since the port was last opened. Dribble Bytes The Dribble Bytes field shows the number of extra (not expected) bytes (characters) received since the port was last opened. 3.2.7.
Diagnostic parameters include: Voltage - Supply voltage (in volts) Temperature - Internal case temperature (in Celsius) RSSI Level - Received Signal Strength indicator (in volts) RSSI Level - Received Signal Strength indicator (in dBm) Power Set: Transmitter power digipot setting Mod Balance Set: Transmitter modulation balance digipot setting Tx Dev Limit Set: Transmitter devation limit digipot setting Tx Dev Level Set: Transmitter deviation level digipot setting Front End Set: Displays receive front end di
3.2.8. ASCII / HEX TERMINAL The Terminal Screens allow the user to select an ASCII or Hexadecimal Terminal Screen for the Primary and Secondary COM ports that were configured in the Port Settings screen. The data is sent according to the port configuration (setup in the Port Settings screen). NOTE: A modem is required to utilize this feature.
SECTION 4 ALIGNMENT AND TROUBLESHOOTING 4.1 GENERAL 4.1.1 PERIODIC CHECKS This module should be put on a regular maintenance schedule and an accurate performance record maintained. Important checks are receiver sensitivity, transmitter frequency, modulation, and power output. It is recommended that module performance be checked annually even though periodic checks are not required by the FCC. Section 4 outlines these tests. 4.1.
4.2.3 TRANSMIT DEVIATION Transmit deviation is preset at the factory. It is adjustable utilizing the JSLM2 Field Programming Software. Select Parameters Settings/Transmit Deviation Level. The value is changed by: 1. Un-check the Default box 2. Highlight the value 3. Change the value a. Increment by 1 using the Arrow Up/Arrow Down keys b. Increment by 10 using the Page Up/Page Down keys After changing the Transmit Deviation Level, a Write must be performed to the JSLM2 transmitter.
PROBLEM No/Poor Transmit CHECK z Verify power supply voltage. z Verify power supply voltage can source 2000 mA minimum. z Verify proper programming including frequency and time-out-timer. z Check system VSWR, feedline loss, connectors, and antenna. z Check radio output power with wattmeter.
