10.4. 10BASE-T/100BASE-TX Terminal Connections
Use this terminal to remotely monitor or control cameras connected to the Digital Video Recorder, or search or
play back their recorded images on a PC web browser. When connecting a PC directly to the Digital Video
Recorder, use a network crossover cable. Use the straight-through cable for connection between them via a
switching hub.
10.3. Control I/O Terminal Connections
The control input and output terminals include: priority recording terminal, camera control terminal, remote
controller input/output terminals, control output terminal, and time synchronization input/output terminals.
(Refer to p. 14; Nomenclature and Functions.)
Note
Ensure that the cable is securely locked into the terminal after connection. (Refer to p. 24; Alarm input
terminal connections.)
10.3.1. Time synchronization input/output terminal connections
Two different methods are available to synchronize the time, one using both master and slave units, the other
using NTP. (Refer to p. 100; Date/time setting.)
Note
When synchronizing a single-channel Digital Video Recorder, set the synchronization interval to “5 seconds.”
(Refer to p. 100; Date/time setting.)
To synchronize the times of slave units with the time of the master unit, connect the slave units to the master
unit in a series via their input and output terminals. In other words, connect the input of slave number 1 to the
master unit’s output and the input of slave number 2 to slave number 1’s output, and so on.
