Connecting External Devices

Devices that can be connected to Eco4 include:
Storage devices
Alarms and relays
Ethernet networks
Dial-up modems
If you do not require any of the above devices to be connected to Eco4, move on
to 'Configuring Eco4' - Page 9.

Connecting storage devices

Images are recorded to the internal hard disk for instant playback and searching
by the operator. The capacity of the internal disk affects the amount of images
and time that can be recorded. For example, a Eco4 with a 40GB hard disk can
record for 8 days, while a 160 GB hard disk allows one month of recording.
The internal hard disk is a temporary storage device as the images are constantly
being overwritten after a certain period of time. If images need to be kept for
longer then external storage is required. The 50-way high density SCSI-2 port on
the rear of the Eco4 is used to connect to external storage, such as CD writers.
Images can be copied from the internal hard disk onto CDR disks for long term
storage. CD's are ideal for recording relatively small amounts of images such as
events, video clips, or incidents. These images can be played back on any PC with
a CD drive and DM Playback software installed.
Compatible CD writers include: Yamaha CRW2200SX, Yamaha CRW3200SX,
Yamaha CRW-F1SX, Plextor Plexwriter PX-W1210TSE and
Plextor Plexwriter PX-W4012TSE (recommended)

Connecting Alarms and Relays
Dry contact alarms can be wired directly to the alarm connection on the back on
the Eco4. There are 5 alarm inputs, one for each camera, and a global alarm
input.
The alarm connections are as follows:
(View from plug solder side)
The polarity of the alarms - normally open or normally closed, can be set in the
'Camera setup' menu.
The global alarm input is used to set or unset the schedule function.
An alarm trigger performs the following actions:
Set
Close relay 1.
Display the alarm camera on the main monitor.
Interleave record the alarm camera.
