Description of device terminal
The time synchronization module terminal is green 6-wire Phoenix terminal,
supporting GPS pulse time synchronization and IRIG-B time synchronization.
See table 7 for the terminal definition.

Under GPS pulse time synchronization method, IN1 and IN2 terminals are
pulse input terminals, TXD, RXD and GND terminals are serial port
connection terminal, in which TXD is sending line, connected to the receiving
line of opposite terminal and RXD is the receiving line, connected to the
sending line of opposite terminal and GND is grounding under RS232; TXD
connects to 485+ and RXD connects to 485- under RS485.
Under IRIG-B time synchronization method, IN1 and IN2 terminals are input
terminals, whether pulse time synchronization or level synchronization, IN1 is
positive input terminal and IN2 is the negative input terminal and GND
terminal is shielding grounding.
The selection of time synchronization method relies on the hardware jumper
and completed by coordinating with J5-J11 and J13 on the module. See table
8 for the specific use method.
