current input - 4…20mA
3.7.4. Real time clock (RTC)
MT-021 Module is equipped with astronomical time clock (RTC).
The clock is a base for defining working cycles of module, timers and time stamps for
measurement results recorded in registers. Imprecise clock setting results in faulty time
stamping and subsequent loss of vital information. For that reason, it is recommended
to set the clock to UTC time instead of the local time zone of the module's placement.
CAUTION!
The clock setting has to be repeated if the module was turned off
for long time.
Setting the time is described in configuring mode documentation for the MTManager
program. There is also a method for setting the RTC remotely using SMS configuration
commands described in chapter Starting the module/Remote configuration via SMS.
3.7.5. USB port
MT-021 module is equipped with one USB port.
This port is intended for the local configuration of the module's parameters and readout
event logger. The port should be connected to an external PC computer with the
configuration program running (MTManager) or software for reading event logger (MT
Log Reader).
