13.4. Combination With The Digital Video Recorder/ Multi-switchers (C-MS91D and C-MS161D)
The Digital Video Recorder has been designed with an emphasis on the synchronization with the TOA Multi-
switchers (C-MS91D, C-MS161D).
By synchronizing the Digital Video Recorder with the Multi-switcher, the following advantages – unavailable to
conventional systems using analog time-lapse VCRs – can be realized.
1. The Multi-switcher does not need to be operated when operating the Digital Video Recorder.
2. The Digital Video Recorder’s main menu screen or search screen can be easily displayed, facilitating
settings and search operations.
The combined Digital Video Recorder/Multi-switcher system is called a basic system in this manual.
Since the Multi-switcher has 2 VCR output terminals, hard disk space can be doubled by connecting two
Digital Video Recorders. This system is called an expansion system. The expansion system does not permit
the synchronization between the Digital Video Recorder and the Multi-switcher.
13.4.1. Basic System
Perform connections as shown in connection examples. (Refer to p. 43)
Set the Multi-switcher (C-MS91D and C-MS161D) and the Digital Video Recorder as follows:
13.4.2. Expansion System (Series Recording)
Perform connections as shown in connection examples. (Refer to p. 44)
The Digital Video Recorder settings are as follows:
• Operation
If the first Digital Video Recorder’s hard disk space becomes full, a signal is provided from the Disk Full Output
terminal. When the signal is received at the second Digital Video Recorder’s Recording Start Input terminal, its
Disk Full mode is reset, allowing recording to be started in the second unit.
Note
• Recording operation and Internal Timer Recording cannot be performed at the front panel of the Digital
Video Recorder set to Disk Full mode.
• Multi-switcher can be synchronized from the unit set to master through the RS-232C interface.Set
Communication Setting’s Switcher Synchronization to “TIME SYNC.”

Note
*1Use the Digital Video Recorder’s date/time display function for date/time display. If set at both the Multi-
switcher and Digital Video Recorder, characters overlap and cannot be seen clearly.
*2Recording Pattern, Motion Detection Pattern, Camera/ VCR mode selection, and Time Synchronization
switcher functions can all be controlled by the Digital Video Recorder. However, when syncronizing the
switcher's clock from the Recorder, set the Recorder's clock Time Synchronization setting to "MASTER."
Time synhronization cannot be performed if set to "SLAVE."
When only performing time synchronization, set the communication swither synchronization setting to
"TIME SYNC." Please note that in this mode Recording Pattern,Motion Detection Pattern, and Camera/
VCR mode selection functions cannot be controlled.
