T-Sync
Model MTS200 transmits NMEA time frame from COM1 terminal at rear panel of unit at
every 1 second at 9600 (baud rate), 8 (Data bits), N (NONE parity), 1 (1 stop bit). The NMEA-0183
$GPRMC serial time string contains time and date of position fix, speed and course information.
INFORMATION
The serial communication settings of COM1 terminal including type of frame,
baud rate, parity and stop bit are fixed and cannot be changed.

TER
T-Sync
Model MTS200 transmits T-format time frame from COM2 terminal at rear panel of unit
at every 1 second at 9600 (baud rate), 8 (Data bits), N (NONE parity), 1 (1 stop bit). User can change the
serial communication settings using keypad on unit front panel as explained in section 9 or console base
configuration utility as explained in section 9.2 or webserver as per section 13.4 or snmp as per section
13.3.
