The DVR, model SLD240, is a storage media of digital video images, which uses hard disk drives
instead of VCR tapes to store video. It enables you to enjoy the extreme flexibility of digital image
archiving instead of clumsy tape management, and it is compatible with most multiplexers on the
market. With a wide range of comprehensive features, such as playback picture-by-picture, quick
search by time and event, an Ethernet connection for remote viewing, the upgradeable software of the
system, the expandable capacity of the hard drive, and much more, the DVR makes your applications
far more flexible and effective than ever before. The DVR is going to prove to be the timely substitute
for the Time-lapse VCR.

3.2 Hard Disk Drive Installation
The DVR is equipped with two compartments for hard disk drives. The unit usually comes with one hard
disk drive installed in the compartment HD1, which is default-configured as a master. If you need a
second hard disk drive, it should be installed in the compartment HD2 (Mobile). If there is only one
hard disk drive, and it is in the mobile compartment, please set the HD2 USAGE option to REC (Please
refer to Section 5.5) before proceeding to record. The jumper-settings arrangement of installed hard
disk drives for the system (Table 3.2 A. ) is shown in the tables below.

3.4 Updating System Software
If the system software of the DVR needs to be upgraded, please take the following steps to safely
update it.
Important: Before carrying out the following procedures, please ensure the SD card is working
and the software system file on the SD card is intact.
1. Turn off the DVR.
2. Insert the SD card into the built-in SD slot on the front of the unit.
3. Press and hold the Up and Down buttons simultaneously, and then turn on the unit.
4. Keep holding down the buttons until the DVR sounds a tone and display the message “ XXXXXX
BYTES READ” Now the DVR is updating the system software, which will take approximately 90
seconds to process.
5. Restart the unit when the device sounds a tone twice and displays the message “ PLEASE RESTART”
The process is complete.
(If you have followed the procedures 1-5 and the unit is not able to power on, please check if the SD
card you are using is functioning and the file is intact. After this has been completed, start
procedures 1 - 5 over again.)
6. Verify the version of the system software. (Please refer to Section 5.6 VERSION option)

Warning: Don’t interrupt the process while the unit is updating itself or insert an SD card that
contains no updated software. If these instructions are not followed, the system may
freeze.

4. BASIC OPERATIONS
This section shows you how to operate and manage the DVR.
4.1 Configure 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 th e hard disk
drives. Generally, the DVR comes with a built-in hard disk drive for continuous recording from one to four
weeks under most recording conditions. Table 4.1.2 shows the possible recording times based on an
80GB hard disk drive at certain refresh rates and the corresponding image quality. With one or more
hard disk drive(s) in operation, please calculate the necessary recording time using the table below. For
example, if the unit is set to record images with BEST quality at a 60 fps record rate, n ormally an 80GB
hard disk drive will be filled in 15 hours (See the gray area in the table). If a 240GB hard disk drive is in
use under the same refresh rate and picture quality, it will be filled in 45 hours (3 times the rate of an
80GB hard disk drive).
Set up the REC Time Mode when a multiplexer is connected
If a multiplexer is connected, for optimum image recording and playback, the record speed of the
multiplexer must be correctly adjusted to match the DVR and set the MULTIPLEXER option on the
setup menu to ON. This can be done by the method detailed below.
4.1.1 Multiplexer Setup
Connect the SW. OUT terminal in 9-PIN D-SUB connector on the rear panel of the DVR to the
multiplexer’s trigger contact. The DVR will provide the timing signal to the multiplexer.
Note: The DVR will only send out a timing signal while it is in RECORD mode.
In the multiplexer’s menu, set the recording mode to SYNC for recording in all DVR refresh rates except
60fps and 30fps. In SYNC mode, if the DVR changes the recor ding speed, the multiplexer will
automatically adjust the recording to match. Be sure to set your multiplexer’s timing signal to falling. If
you wish to record in 60fps or 30fps, put the multiplexer in real-time instead of SYNC. 60fps and 30fps
timing signals are constantly negative/falling.
