4. BASIC OPERATIONS
This section shows you how to operate and manage the unit when it gets in the way.
4.1 Configuring Recording Settings
Recording Time settings (Recording Rate and Picture Quality Setting)
Recording time will vary depending on the image size, recording rate, and the capacity of hard-disk
drive. This unit ships with a 80GB hard disk for continuous recording from one to eight weeks under
most recording conditions. The table below shows recording times based on the 80GB hard-disk drive
at certain refresh rates and the corresponding image quality. With one or more hard-disk drives in
operation, please calculate the recording time using the table below in accordance with your
requirements. For a NTSC unit, for example, if the unit is set to record images with HIGH quality at a 60
fps record rate, normally a 80GB hard-disk drive will be filled in 12 hours (See the gray area in the
table). In a 2nd 80GB hard disk drive is added, under the same refresh rate and picture quality, both
drives will be filled in 24 hours.
Set up the REC Time Mode when a multiplexer is connected
For optimum image recording and playback when a Multiplexer is used, the record speed of the
multiplexer must be correctly adjusted to match the unit. Set the MULTIPLEXER option on the main
menu to ON. This can be done one of the two methods detailed below.
(1) If an Toshiba multiplexer is connected for use, you can program the REC time mode of the
multiplexer by referring to the table below (each refresh rate refers to one REC time mode).
(2) For a multiplexer other than Toshiba. Please, connect the SW. OUT terminal on the rear panel of the
DVR to the multiplexer’s trigger contact. The DVR will provide the timing signal (Negative/Falling) to
the multiplexer. Thus, if the DVR changes the recording speed, the multiplexer will automatically
adjust the record to match. The DVR doesn’t provide a 2-hour timing signal in NTSC or 3-hour
timing signal in PAL.
