Refer to Figure 1-4. • External Speaker Jack • J104 provides repeater audio output to an external speaker. The local volume control adjusts the volume level of this speaker. • Speaker/Microphone Jacks • Indicates that the CW Identification is being transmitted on the lowest-frequency repeater.
INTRODUCTION AND OPERATION 1.12.4 POWER SUPPLY code and Home repeater number are the "address" of the mobiles in the system. Therefore, up to 1250 separate addresses can be assigned in a 5-repeater system and up to 5000 can be assigned in a 20-repeater system. An ID code may be assigned to an individual mobile or a group of mobiles as required. The 2000 Series Repeater Power Supply is a quad output 800W supply with power factor correction.
INTRODUCTION AND OPERATION 1.14.2 MOBILE DATA MESSAGE ORDER 1.14.3 ID VALIDATOR OPERATION Each repeater monitors all the time slots on the repeater data bus. If it detects its number in another time slot, it begins transmitting an additional data message to its mobiles. This message tells mobiles programmed to detect that ID code to go to that repeater to receive a call. This additional message continues for as long as the mobile is transmitting on the other repeater.

INSTALLATION Secondary protection (other than grounding) provides the equipment protection against line transients that result from lightning. There are two types of secondary protection, RF and Telephone Line. Use the same wire sizes as specified for coaxial cables for any ground connections required by the secondary protectors. The operating temperature range is -30°C to +60°C (-22°F to +140°F), i.e. the same as the repeater. The fan is thermostatically controlled by the internal temperature.
INSTALLATION For example, a high-speed diode reacts first, clamping a voltage strike within 10 ns, a heavy duty heat coil reacts next to reduce the remainder of the current surge, and a high-powered three-element gas tube fires, grounding Tip and Ring. 2.7.1 PROTECTION GUIDELINES Follow these guidelines for grounding and lightning protection. Each Repeater installation site is different; all of these may not apply.

SOFTWARE SECTION 3 SOFTWARE 3.1 INTRODUCTION Follow the computer instructions for loading the disk. The MS-DOS Revision 2.0 or later operating system is needed to run the programs. The computer needs to have RS-232C capability, for example, the Serial Card in slot "COM1" or "COM2". The Johnson Summit QX Repeater Program on 3.5 inch disk, Part No. 023-9998-297, uses an IBM personal computer to program the EEPROM Memory in the Main Processor Card (MPC).
SOFTWARE 3.1.6 COLOR OR MONOCHROME OPERATION out affecting programming. Since EEPROM memory is also reprogrammable, a new device is not needed if programming is changed. The programming software utilizes color for a color monitor and video card. However, with LCDtype displays, this may make some information hard to read because the contrast is poor. To improve contrast, a monochrome mode can be selected in the display mode from Utilities heading. 3.1.
SOFTWARE are also being loaded into conventional memory. Contact Customer Service for information on how these programs can be moved or disabled to make more space available. To make a programming disk, format a blank disk using FORMAT B: or FORMAT B: /S (use "/S" if it must be a bootable disk). Then copy the required program file or files to the programming disk. To do this, type COPY A:(filename.ext) B:(filename.ext). For example, to copy the file 2000pgm2.exe from drive A to drive B, type 3.
SOFTWARE 3.5 HELP F1 Help screens are available for most parameters and options in this program. Whenever a parameter or options clarification is needed, press F1 and if a help screen is available it will pop-up on the screen. Press Escape to exit the pop-up screen.
PULL DOWN MENUS SECTION 4 PULL DOWN MENUS 4.1 MENU DISPLAYS 4.2.1 LOAD The menus available are listed at the top of the screen (see Figure 3-2). Move the cursor with the arrow keys to highlight the menu name. Press Enter to view the menu and the arrow keys to scroll through the menu. Call up the highlighted selection by pressing Enter. Load reads information from a stored file. The program requests the filename to be loaded into the buffer.
PULL DOWN MENUS 4.2.4 NEW 4.2.6 DOS SHELL This menu selection erases all Site and Repeater information in the programmer and loads factory defaults. If the current data has been changed, selecting File -> New provides the opportunity to save the data before loading the defaults. DOS shell temporarily suspends the program and returns to DOS. Directories and other DOS commands can be performed. To return to the program from DOS, type EXIT and press Enter. 4.2.7 QUIT (ALT X) 4.2.
PULL DOWN MENUS • 4.3 EDIT Area This is the same as the area bit used when programming the mobiles. This bit is usually "0". • Sync Repeater None is used for LTR system repeaters. • Figure 4-5 EDIT MENU Select if the repeater is not connected to additional repeaters via the high speed data bus. This menu is used to create new files and set or change the repeater operating parameters. The filename for the repeaters in this file is shown in the lower left corner of the screen.
PULL DOWN MENUS • Power Source Use the arrow keys to move down the list. Use the Space bar to toggle through the parameters: Disabled, Active Low, Active High, for each alarm. This indicates the primary power source for the Repeater (AC/DC). If AC is selected and Battery Backup is installed, the transmitter goes to half rated power (max.) when AC fails. If DC is selected and AC fails, power output is unchanged. • • There are four input alarms that can be activated by external devices (see Section 6.
PULL DOWN MENUS • Alarm Description 4.3.4 REPEATER TYPE This is a text string (up to 15 characters) to describe the alarm. This test string is sent via Morse code if the alarm input is programmed with a Tx ID and an output is selected in the cross reference menu (see Figure 4-10). • This screen (see Figure 4-11) selects the repeater type (LTR signaling protocol and features): Frequency Band Transmit ID 800 MHz 800 MHz [-12.
