This box must be checked at all times.
Checking this option will tell the unit to copy all received data from the GPS
module's serial port to the serial port on the back of the Time Server. The copied
strings are the standard NMEA GPS data strings.
3.2.14 Serial TTL Level Outputs Checkbox
This box must be checked at all times.
Checking this option will enable the TTL level outputs of the serial port. These are found on Pins
7, 8, and 1. To receive the actual NMEA strings, the “Echo GPS Strings Checkbox” must be
checked. Pin 7 is the data from the GPS module, Pin 8 is data that will be sent to the GPS
module through the RS-232C port echo'd at TTL level. The data pins are duplicates of the RS-
232C data found on Pins 2 and 3, but are provided before conversion to RS-232C levels. Pin 1 is
the 1 PPS output. The 1 PPS output is a very narrow signal on the order of 1 uS in width, active
high.
3.2.15 Debug Output Checkbox
The debug output checkbox will tell the unit to output debug and operational information to the
serial port.
3.2.16 Unit Name

3.2.17 Password
The password field displays the current password. To change it, enter a new password, push Save
and then Reboot for it to take effect. Time Server passwords are limited to12 characters.
The default password is “tmachine”
3.3 Display Configuration
The time server front panel buttons are used to control and configure only the display and not the
time server engine. Display configuration is accomplished by editing parameters using a simple
menu system. Only four buttons are used to navigate the menu. The Mode button enters the
Menu. The Up and Down buttons move up and down through the menu items, and are used to
change parameter values. The TC button is used to save any changes and exit the menu system.
