Chapter 6 6-6 ATP 3-09.02 16 February 2016 Note. For some HTUs, the screen will go blank even when the LOOP TEST has an entry greater than 0. The POWER light does not blink. This hybrid power-management mode occurs only when using AC power and an adapter. It is unlikely that the HTU will be powered by AC power in the field. If you are using AC power in the classroom, and do not want the student’s HTU screens to go blank, go into page 2 of the complimentary metal-oxide semiconductor screen (press CTRL + ALT + ESC keys during boot up). Change the power management setting to “AC DISABLED.” Enter 999 in the LOOP TEST field in SETUP. 6-20. The setting for power management must be set to “ENABLED” and LOOP TEST must be set to 0 when the class is completed to enable the HTUs to go into maximum power management when using a battery. Without power management, the internal battery will last 4 to 6 hours. PREPARATION FOR OPERATION 6-21. Before placing the FOS device into operation as a communications device, system operation parameters need to be established. These parameters are entered through the INITIALIZATION MENU selection (option J) from the MODE MEDE. INITIALIZATION MENU consists of the following screens: Required: SETUP, NET STATUS, MEMBER DATA, and MAP MODIFICATION DATA. Optional: MEMBER MONITOR, URN, SELF-LOCATION, SURVEY FORM HEADER DATA, and MESSAGE LEGALITY TABLE SETUP. 6-22. The SETUP, NET STATUS, MEMBER DATA, and MAP MODIFICATION are the minimum number of screens that must be completed when you first initialize the FOS. The FOS is not operational until the four required screens have data. 6-23. Local address and observer number information can be found in the current signal operating instructions (SOI). To ensure communications with other elements, member data (address, observer number, and device type) must be entered. Member data can be entered by selecting MEMBER DATA (option D) from the INITIALIZATION MENU. (See TB 11-7021-228-10-1 for detailed information on entering member data. Local SOPs will dictate the elements that will be entered into the member data table.) SECTION II – COMMUNICATIONS PROCESSING 6-24. The FOS provides data communications over a wide range of military communications equipment and communications security devices. This section explains how to establish communication. 6-25. The FOS SETUP file requires the FOS observer number, FOS address, unit name, and the unit reference number (URN). The operator must also enter the date, time, and the time zone. (Refer to procedure 2-4 in TB 11-7021-228-10-1 for more information.) 6-26. After entering the FOS setup information, the operator may enter up to four nets. Four nets are available if an external tactical communications interface module (TCIM) is connected to the LCU. The NET STATUS screen will display four nets only when the external TCIM has small computer system interface (SCSI) address set to 5. (Set the address before the external TCIM is turned on. Turn on the TCIM before the LCU boots up.) Only two nets are available for the HTU. The net list is displayed on the NET STATUS LIST. This list shows which net(s) are currently in an activated status. Information for the individual net is entered on the NET STATUS display. The NET STATUS display is accessed by selecting a blank or existing record from the NET STATUS LIST. If the entry in the CONNECTION field on the NET STATUS display is changed, a new set of default entries is displayed in the remaining fields. Enter all necessary information. Then observe the prompts at the bottom of the screen. The prompt, <D/A>=DE/ACTIVATE NET, initiates a command for terminating or activating the net. Press the A key to load net parameters into the modem, enabling communications for that net. Press the D key to terminate communications for that net. (Refer to procedure 2-5 in TB 11-7021-228-10-1 for more information.) 6-27. There is no requirement to enter a URN and unit identification (ID) for each nonmember when the FOS is being initialized. However, the operator must enter the information before transmitting or receiving
