Technical Data
Time Synchronization IRIG
Nominal input voltage: 5 V
Connection: Screw-type terminals (twisted pair)
Front Interface RS232
Baud rates: 115200 Baud
Handshake: RTS and CTS
Connection: 9-pole D-Sub plug
RS485
Master/Slave: Slave
Connection: 9-pole D-Sub socket
(external terminating resistors/in D-Sub)
or 6 screw-clamping terminals RM 3.5 mm (138 MIL)
(terminating resistors internal)
or fiber optic connection (ST plug)
In case that the RS485 interface is realized via terminals, the
communication cable has to be shielded. The shielding has to be fixed at
the screw that is marked with the ground symbol (rear side of the device).
Boot phase
After switching on the power supply the protection will be available in approximately 45 seconds. After
approximately 80 seconds the boot phase is completed (HMI and Communication initialized).
