Once device internal clock is synchronized with gps receiver, ntp driver will always maintain internal
clock accuracy with few hundred microseconds w.r.t gps receiver time in lock conditions and holdover
conditions (as per holdover ppm accuracy of internal rtc) during normal run of device.
Also, the GPS LOCK led will gl
ow “green” color and gps lock status will be updated on other outputs
as well.
All messages showing unit LOCK/UNLOCK status, position information, day of year, day, COM2
terminal time frame format are displayed in rotation in last line of LCD.

Model MTS200 device. When Power
is applied to the device, GPS LOCKED indication illuminates in RED color. If GPS Antenna is
connected, after few minutes, GPS will get Lock and will be indicated by GREEN indication on GPS
LOCKED led. The time taken to get GPS lock will depend on start mode of GPS receiver whether
GPS receiver is in Cold start or Warm Start or Hot start mode.

Model MTS200 device provides relay contacts on its terminal at back panel of unit for
Power, GPS Lost and Watchdog output. Factory set configuration for relay contacts for all three
mentioned outputs is C-NO terminal.
After device is Power ON, Power relay output is energized.
After time is displayed on device display, watchdog relay contact gets energized after 5 to 6 seconds.
Watchdog relay status indicates the healthy functionality of unit. If unit becomes unhealthy, the
watchdog relay output will be off after few seconds and watchdog LED in front panel will be ON. It will
maintain its output status till the unit regains its healthy status.
If device is in LOCK condition, GPS LOST relay will be in energized condition and GPS LOCK led on
front panel will be ON.
All other event outputs including standard event output and additional event outputs (optional) are ON
as per respective event time configured. Standard event output is configured at every 1 minute event
and 1 sec event ON period.
Factory set setting of all additional event outputs (optional) are set as 60 seconds event time with 50
milliseconds event ON period.
Time and date displayed on unit will be in I.S.T. format (UTC + 5:30 hrs)- Indian Standard Time
format and all other parameters such as gps lock status, gps parameters and other will be display in
sequence at 5 or configurable seconds interval. If the parameter on display
Once unit is Power up and time is displayed, unit will start transmitting serial NMEA frame on COM1
terminal located at back panel of unit. NMEA output communication settings will be at 9600, 8, N, 1.
NTP outputs will be at configured factory set factory IP address and will be active once NTP client
request are received on particular NTP port. IRIG-TTL output will be at TTL voltage level i.e. 0(low
level) and 5V(high level) and IRIG-AM (Amplitude Modulated) output will be available at 3.6Vpp.
8.4 Basic Normal Run Mode Operation
After unit is boot up completely and time is available on display, all the outputs of unit i.e. event pulse
outputs, IRIG, NTP and serial time outputs will be available as per unit clock.
MTS200 size unit display supports 20 x 2 lines LCD which displays parameters such as time with
local/UTC information, date with day of week, GPS LOCK/UNLOCK status, position information, day
of year, type of serial frame format on COM2 terminal, ntp pps offset value, configured timezone, DST
ON/OFF status.
Parameter such as Time is always displayed on First line of LCD display.
Other parameters such as Date, GPS LOCK/UNLOCK status and total satellites visible by receiver,
as position information, day of week, day of year, type of serial frame format on COM2 terminal, ntp
pps offset, timezone and dst information are display on 2
nd
line of display. These parameters are
displayed in rotation as per configured interval
or can be stopped by configuring parameter “Display
Update Rate” to 0 using front panel keypad.
During normal run mode of device, there are several messages displayed on LCD screen of unit as
per condition prevail. Below are messages which are available on display screen of unit.
Each Ethernet port Live / Not-Live status will be display on LCD screen. If RJ-45 cable is connected
