Model MTS200 is shipped with factory set Ethernet configuration (IP,
gateway and subnet address) or DHCP. For DHCP to work properly there should be DHCP
server available in network.
2) Check the connection route from

Model MTS200 Ethernet port to end device
and configuration of intermediate Ethernet switches and gateways.

Model
MTS200 Ethernet port addresses of subnet and gateway should be configured as per
network domain architecture.
3) If the unit is directly connected to remote PC using RJ-45 cable, it is recommended to
connect unit through Ethernet switch or using cross RJ-45 cable configuration.
4) User should configure the IP address of all Ethernet outputs as per network domain
configurations where
mas

T-Sync
Model MTS200 device is to be installed. User can
configure IP address of Ethernet port using telnet connection with respective Ethernet NTP
port. It is recommended to Power recycle the unit after all Ethernet NTP ports are configured
with new IP address.
17.11 NTP client not synchronizing with GPS NTP output port
Following steps are to be checked for issues of NTP communication failure or NTP client time not
synchronizing with GPS NTP Server port.
1) IP address of GPS NTP port and NTP client device should be same network domain.
2) Please verify the Ethernet connection between GPS NTP port and NTP server device by
pinging the IP address of GPS NTP port. If IP address of GPS NTP port is not reachable,
NTP communication will be failed.
3) GPS NTP Server port IP address should be properly configured in NTP client device.
4) MTS200 internal ntp driver must have synchronized with GPS Receiver.
5) If Authentication settings are done in MTS200, then user need to configure ntp client device
with similar type of authentication if and only if authentication is required at client side. Refer
section 11.3.3.4 for details regarding NTP Authentication.
6) Various NTP parameters should be configured properly in NTP client device.
7) If ntp client device is a computer machine based on Windows or Unix based or Linux based,
please refer manual Appendix C for proper configuration and time synchronization method of
client device.
8) Please refer section 11.3.4 and manual Appendix C for understanding NTP client time
synchronization method.
17.12 Loss of time synchronization by NTP Client during GPS Unlock
If NTP client loses time synchronization when

Model MTS200 is in Unlock
condition and resume when
mas
TER
T-Sync
Model MTS200 comes in LOCK condition, check the
configured NTP stratum value in
mas
TER
T-Sync
Model MTS200 device. It should be less than
15 or applicable value depending on NTP hierarchical architecture arrangement as explained in
section 11.3.
17.13 Loss of time accuracy in NTP, IRIG-B, event outputs during Unit Power ON in
Unlock conditions
When

Model MTS200 comes in UNLOCK condition from LOCK condition during
normal operation, unit enters in holdover mode. Refer section 14 for technical explanation of
holdover mode.
