    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”...

    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.

  • Page 22: Radio Tab

    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 +1.5/-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.

  • Page 23: Setup Radio Parameters Screen

    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.

    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.

    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.
  • Page 26 Figure 3-7 Serial PC Port Settings Screens COM Port The COM Port field allows the user to select the COM port number (1-4) for the Primary and Secondary COM port. Baud Rate The Baud Rate field allows the user to select the communication speed for the Primary and Secondary COM ports. Data Bits The Data Bits field allows the user to select the number of Data Bits (4 - 8) to transmit or receive over the Primary and Secondary COM ports.
  • Page 27 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.

    3.2.6 PORT STATISTICS The Port Statistics utility shows some of the statistics of the PC’s serial COM ports (Primary and Secondary). (A check in the check box indicates an active state).No entry is allowed in these fields. Figure 3-8 Serial PC Port Statistics Screen Baud Rate Baud Rate displays the baud rate of the transmitter.

  • Page 29: User Test

    The Framing Errors field shows the number of Framing Errors received since the port was last opened. 3.2.7. USER TEST The User Test Utility allows the user to test the functionality of the JSLM2. This utility makes diagnostic information available and gives the user the ability to change channels and transmit or receive a modulated signal.

  • Page 32 242-2110-XXX for VHF models. The DL-3282 Modem is part number 250-3282-002 and is available as Bell 202 or Bell 103 format. Combined with an interface cable (part number 697-3414-003), the transceiver and modem provide a reliable 300 baud or 1200 baud RS-232 serial Dataradio system. Setup: DL-3282 Modem: The DL-3282 modem does not require special programming for normal Bell 202 or Bell 103 format.
  • Page 33 +7.2 VDC or +12.5 VDC. If supply voltage exceeds +11.25 VDC, attention must be paid to the transmit duty cycles listed in the JSLM2 User Manual (001-2100-XXX). Failure to observe the maxi- mum duty cycle could result in premature transmitter failure.
  • Page 34 Clicking OK will close the Settings (or Radio, Frequencies) window and save current settings to local mem- ory. A Write must be performed to program settings to the JSLM2. Connections: Connection between the JSLM2 and DL-3282 is made with the interface cable (697-3414-003). Figure 1 Typical JSLM2 - Modem Configuration Connection 001-2100-XXX...
