The table below shows optional modules, used for such as time synchronization, data transfer
of Modbus and IEC60870-5-103 connection.

IRIG-B000
IRIG-B000 module is used to receive the digital signal generated with an external clock; the
signal is in conformity to serial IRIG-B000 format. Note that the IRIG-B000 module is able
to receive digital signal (TTL) only (i.e., the reception of AM signal is not applicable). This
module is isolated using a photo coupler; the user should note A2 and B2 connectors are not
used. The peak value of IRIG-B000 signal should be greater than 3.5 volts; the IRIG-B000
module has the input resistor (about 3k ohm). Thus, the terminal resistor can be required
when the IRIG-B000 signal is delivered for several devices; the value of the terminal resistor
depends on the number of deliveries and the performance of the external clocks. For setting
of time synchronization, see Chapter 5.8.
