CHAPTER 4
MENU SYSTEM
4.0 GENERAL
The TYMSERVE 2000 provides a menu system accessible via the front panel keyboard and
LCD display for setting the Internet address and other parameters. These parameters are stored in
EEPROM (-ACTS version also uses battery backed SRAM for some parameter storage) to
sustain these settings during loss of power to the Server.
4.1 TYMSERVE 2000 FRONT PANEL
The TYMSERVE 2000 front panel (shown in Figure 4-1) provides a 2 line by 40 character LCD
backlit display, a keyboard, and the power on/off switch. The main display screen shown in
Figure 4-1 displays the user's local time. If the timing source is lost, the word 'FLY' (-GPS,
-IRIG) is also displayed to indicate that the TYMSERVE is 'flywheeling'. The -ACTS version
displays call and phone line status on the front panel.
